6:24 I'd fine-align again after deleting the floor. One object has a floor, the other does not. This might confuse the aligner. Also, because these are 2 different objects, each might have an ever so slight scaling deviation from the other. I suspect this is where the 0.2mm error came from

Really great you taking your time to explain things, the item could be hung on fishing line and then do all photos in one hit.Quite keen to try this method.
Hi, the part is not allowed to move during the individual pictures you take. So in all pictures the parts has to remain in the exact same position. Otherwise the photogrammetry process will not work.
@@Holocreators You're obviously smarter than the average bear. So please forgive me if I sound pretentious. I like David Butcher's idea. And it beg's the question... Why should the part not be allowed to move? Would it be so that the object maintains some point of reference to where it sits, in relation to the camera? If so... then wouldn't the surrounding objects (to which the main object is resting on) become part of the main object? Yes. They would.

The object being photographed is the ONLY true point of reference. The object's background, OR WHATEVER IT'S RESTING ON in any photo is irrelevant, since it gets edited out anyway. So... why would anything extra, connected to the main object, be necessary? Why would having your camera shot conform to an x/y axis, in relation the object's center, be necessary when either x or y is not a constant? Because the ONLY REQUIRED points of reference are with the object. Anything else is irrelevant. And, then again... I could be wrong. My apologies if I've missed something. Thank you taking time & making the effort to post this. Much appreciated.
@@Seemsayin Hi, I am no scientist and I don't know how photogrammetry software really works. The way I understand it is that in a first step the position from where the photos were taken needs to be calculated. That is easier when the object remains stationary, because then the background can also be used for the camera position calculation. But photogrammetry software gets better and better and it could be that its now also possible to have the object aswell as the camera move. As long as the object itself doesn't change.
Brilliant! It seems like a lot of work (and it is somewhat), but if you only have needs occasionally for a part that is unavailable or prohibitive in price, this is amazing! Thank You very much, very much!
Damn this is awesome, now i can 3d print anything i want, i just had this idea of scanning something and converting it to stl 3d model from pics, didnt think this was actually this affordable.
Hi Martin, yes you can. The Scans can look rough sometimes and cutting away unwanted elements just in meshlab can be not enough. Then you should probably also open the scans in blender and do some more cleanup there. But then you can scale it and export and 3d print it. Have a wonderful day. Kind regards. Swann
Taking all those photos looks a little tedious. Curious to see if it's possible to record a video instead, then convert the video to a bunch of images and use those instead. I'm impressed at how good the scan turned out 👍
As my siblings, and I, disposed of the belongings from my parents last house ... I was able to grab an antique (probably early 1900’s) globular, store display, dispensing jar made of glass. Our family over the generations have used this as a cookie jar. As I was cleaning it, it soon became clear that the cover that now exists was not the cover it originally had. To my best guess the original cover may have been glass, or possibly even a shaped steel sheet. The top of the jar has threads that suggest that it may have gently screwed on. Yes the worst case scenario is to strip the aluminum cover of its paint and repaint it to match the base of jar (presuming it came with the original jar) but then the threads of the actual jar would still be ignored. Questions: Would it be possible to get this jar scanned to both get: • The essence of these threads for reproduction of a new lid? • Would it also be possible to get a scan to capture the glass design with the thought to handing the scan to a glass craftsmen to reproduce a likeness it in a new cover? I am a person with multiple disabilities. The skills needed to produce a new cover for this antique are beyond my skill set. In the past I have tried to contact Minneapolis/St. Paul, Bloomington Minnesota area maker studios and all I have gotten is dead silence. Is there a ‘correct’ way to contact a Maker Studio to connect with a maker who might have the time to work with me on this project? OR is there a company in my area that help with this project?
hello, scanning the threads of the jar is possible with this technique. But you have to take very high resolution images. The scan will then only be a starting point to analyze the thread pitch. this will need to be reconstructed inside a cad software to create a new lid. this new lid can then be 3d printed. I could do all of this for you, the price would be probably around 300-400 EUR. For a more accurate estimate please send me a picture of the jar and needed lid to info@holocreators.com
@@Holocreators Thank you for a response. Your the first company that has actually made a response to my inquiries. I will send a separate response independently of this channel.
What an excellent video, I have absolutely no need of this tech, it just looked interesting and indeed it was, were I 40-50 years younger I may have had a go at it, well made, well explained, well done.
Thanks. Yes I am planning to do a structured light video soon. What kind of tips and tricks are you expecting on that topic? Then I can include that in the next video.
This is an awesome video! But I have scanned a test model before and I didn't have to combine the top and bottom angles, it combined automatically in Meshroom. I think that's only the 2021/2022 update though. Great video!
Out of curiosity, at 4:40 when you're scaling your photogrammetry model, why did you calculate a scaling percentage instead of using the "target size" measurement to input your 76.2mm? It seems like that would give you better accuracy, as there's no rounding of the scaling factor. I mean, obviously the results speak for themselves when compared to the professional scan, but I found that step odd.
I saw your video only today , congratulations , great work I would like to understand how photogrammetry works , I am sure that this video will be useful to me.
At 4:58 you use a comma instead of a full stop entering the scaling 10.917. Is that the reason there is an exclamation mark in a triangle box on the right corner of the screen? Very informative video, thanks.
I think it is a big minus at Meshroom, the program only runs on specific graphics cards. "Meshroom requires an NVIDIA GPU card with a CUDA compute capability >= 2.0 for the MVS part. "
Something that I think should be mentioned at the beginning is the requirements for hardware. You MUST have a NVIDIA graphics card. I have an I-5 and use internal graphics. After going through all of the steps and starting the conversion I finally figured out that It error ed out in step 7. I can understand that they built the software to use a specific hardware minimum, but many of us do not have it and I don't like wasting a couple of hours to find this out. [13:49:26.570938][warning] Could not determine number of CUDA cards in this system [13:49:26.568939][warning] No CUDA-Enabled GPU.

@@Holocreators Thanks. I'm not even sure what the minimum card would be. It's been a long time since I added a video card to my builds as the internal graphics meet my needs.
@@Holocreators I have tried a number of other "free" programs, and feel that Meshroom looks very good.. I just ordered a refurbished NVIDIA card from NewEgg for $30 to try this out. Thanks for what you did with the video, would be great to update with what the minimum hardware would be to get at least a fair result.
@@Holocreators Thanks. I will let you know how this works. The card I ordered is a GeForce GT 730. I have been doing a lot of research and this card seems to meet the minimum requirements. Here is a link to the minimum hardware from Meshroom. meshroom-manual.readthedocs.io/en/latest/install/requirements/requirements.html
This is nice but easier way is to take photos from top, all sides and bottom and then measure diameter of bottom circle and then make new part in Fusion 360 (non commercial version) then save in stl file format and open and finish editing in FreeCad and save also in STL and then open in slicer.
In reverse engineering discipline, it is not very important to be accurate on the surfaces.If there are not drawings(which is assumed,because if they are available, then you can just re-create the part, not need to scan it).And as far as the hole sizes and locations, you can check with caliper and readjust the scan, after you convert it into solid geometry on you CAD program(like SpaceClaim).....This, what you are showing here is very useful information for the industry. Can save a lot of money and time!
I find it very interesting, but it is not clear to my why scanning that object is more efficient than rebuilding it from scratch in a cad program. Seems to me that with some proper measurement tools dimensions can be taken more swiftly than doing all these steps as described in this video and the video about making the step or stl file
Hi, really depends on the part. Freeform organic surfaces are really hard to model in cad. But you are right, this particular part you could have properly solely created in CAD. But I guess you came here for the 3d Scanning ;-)
Very good video. Given you have only a Galaxy S6, but get quite amazing photos for indoor shooting, I wonder what the lighting looks like? Seems like proper studio lighting. Can you please tell us more?
could you scan a motorcycle engine with this method? or would this be a too large geometry for the software? the engine does have a lot of unique points so tracking wouldnt be the issue i believe
Hi Thomas. You can scan a motorcylce engine with this technique. But it would probably be not detailed enough. Especiall the cooling ribs on the engine block will be difficult to reconstruct.
Hands down one of the most beautiful tutorials I have ever seen. Will this work with organic shapes - i want to do a 3d print of my dog ? Any suggestions ? Thank you :)
hi, thanks for your reply. dogs are notoriously difficult to 3d scan. i have done it before. for that i would recommend a hand 3d scanner. you should search for something like artec 3d scan. once you have the file 3d printing is easy. any 3d printing company can do it, i always like to use shapeways
@@Holocreators thank you so much. Unfortunately the prices of this company are way way way out of my budget - i mean 13 - 14 K euro. Thats spicy. Thank you and all the best
I have a plastic part for a car I need replaced. It is no longer available new or used. It is the cover for the electric power seat controls. I have one in good condition, I need the one for the other side which is a mirror of the one I have. Can the one I have be scanned, then mirrored and then 3d printed? If so, who can do it for me as I have no intention of getting a 3D printer and being on the ATF watchlist...
You can't get a 3d printer when being on an ATF watchlist? Thats wild. But to answer your question. We can 3d scan your car part, mirror it and send you the files or 3d print it for your. Please send me an email to info@holocreators.com
Excellent video. It looks like picture-taking (200 pics in your case) is no doubt one of the longest processes in this project- would it be possible to use the Burst function on my iphone camera and use a slow sweeping motion (instead of incremental as you're demonstrating) to make the process a little faster? This should also allow taking of more pics for a better dataset. Of course, all of this is null if the pics are fuzzy. If one found themselves doing this on a repeated basis, a jig is in order- may be my next project :)
Hello and thank you. I think the burst function should also work. Just check the pictures afterwards so they are alle in focus and not blurry. Kind regards. Swann
@@tallcypress I'd avoid the burst function. With photogrammetry you rely on the sharpness of the images. To get perfect results a tripod and shooting one photo at a time is what i recommend.
A turn table is often used to help with this. A steady tripod will also help to keep the distances similar. Then you can lock the focus on the camera so that things stay in focus. You'll probably find that taking pictures from further away helps things stay in focus better, especially with a good camera and a telephoto lens, since the differences of height on the details of the part will be small compared to the distance between the part and the camera, so it will remain in the depth of focus. If you have a decent DSLR camera, you can also use timed exposures or a simple remote to take pictures at regular intervals as you turn the part.
good morning, I dont think this could replace a dental scanner. Inside the mouth there is little room to do photogrammetry. Maybe if you had a very small camera, you could give it a try though.
when you install an extra plugin for sketchfab you should be able to import obj files into it. obj is the file format in which meshroom exports the files
@@Casey-tm6tv Thank you, this could help with the registration of the images. also you should always place a ruler in the scan to make scaling easier later on
Yes you could get a better result that way. But make sure to have an even background then. Like a grey screen. Otherwise the photogrammetry software (meshroom) will be confused because the object in front is turning but not the details in the background!
@@Holocreators thanks for the reply, i'm off to the store to buy some of the greenest fabric available... I have some experience in studio photography and fabrication, trying to get into 3d modeling and printing on my own. This would help a lot.
Could you make a bigger yellow plate or "Studio-green" - and remove that in photoshop, and then dont need to 3d-scratch that off later on, so you only have the core object ?
I'm a senior 3d modeler. not sure how useful are those 3d scanners right now, but i can model a cleaner piece of 3d model using my 3d modeling software than the results that you are showing in about 1/4 of the time.
I had a Galaxy Note 10 which had a ToF sensor (time of flight, similar to a Lidar scanner) , imagine the possibilities if that ToF became mainstream on smartphones
Just brilliant! I tried to scan my all black and shiny Earphones but at the first time it didnt worked at all. But a simple trick made a huge difference. I created a thin layer of flour around it and everything just worked fine. Now I can create my own ear hooks without spending an insane amount of money on Apple Beats. :D Thank you for your tutorial. (Danke Digger!). Maybe you can give this advice to noobs like me for the next tutorial of that matter. (:
Amazing tutorial, it at least let me know that I can keep using Meshroom and save money for better PC hardware. Even though 3DF Zephyr's price is still tempting.
hello, when I use meshroom, I get an error on the second node called feature extraction. and it seems to stop the whole process after that... what do I do???
Awesome tutorial! Loved the presentation style! I wonder if there`s any free or low budget combo i could arrange to improve precision and use this workflow you showcased for GD&T purposes.
I've tried this method, but for me it wasnt very successfull. I have gotten an old car plastic part which i wanted to scan with meshroom, it did, but because of the part is black, the images doesnt give back the true geometry when its processed by meshroom, i tried painting it yellow or something brighter, but that only solved some of the problem. Do you have any recommendations how could i improve my scanning or the results?(after the meshroom process some part of the plastic is missing, i dont know why).
I agree with the horse ;-) . Paint it bright white and add tracking markers. Also the object needs to be well lit so the scanning works well. Use diffuse lighting like in my video please.
Thanks for the great info. 2 questions 1) Can you suggest any similar workflow for a Model wearing a dress. 2) which software is used for the final slow motion rotation of product. Awaiting reply Thanks for all.
Hi, with a dress it can be much more difficult depending on the fabric, just give it a try. unfortunately I don't remember the software anymore i did the rotation with, almost 2 years ago ;-) but Freecad can do such turntable animations. you just let it turn and run a screen recording tool (OBS) at the same time.
Hello I need to create my own characters in scale HO (1:87) Can I scan a person with this technology? and How I reduce to scale 1:82 in the software? thanks
Hi, just4funtrains, yes you can scan a person with this process, if the person holds really still. Please check this video at 4:10 I explain how to do rescaling. Kind regards- Swann
Hi, meshroom provides the files in the format OBJ. Obj can easily be imported into maya or blender. 3dxlm is a dassault systems file format. so you might be able to convert the obj to an stl. then import that stl to solidworks which is a dassault systems product and maybe from there you can do the export to 3dxlm.
What I'd like to know is how to do accurate room-scale 3D scanning (scanning the interior of a room or series of rooms) without having to spend thousands on a specialized device like Leica or Matterport. I got an occipital structure sensor for a few hundred, but the quality I'm lookin for just isn't there. The deviation error can be up to a full inch off, and the iPad memory limits you to about 15 seconds of scanning time before maxing out.
Photogrammetry is not so well suited for room scanning. It can be done, with many individual scans stitched together but its a lot of work. I would highly advise to rent a laser scanner for this task. In Germany you can rent a Faro Focus 70 for 200EUR for one day. Thats enough time to scan an entire house from the inside and the data quality is superb.
Well scanning rooms is very difficult, specially in a precise way, since you have to be at multiple distances from the object, and there is little to reference it (like plane wall with no detail). If you try adding markers that appear in multiple images, it will be easier for the software to produce a good model. Markers can be anything from precise dots (white inside, black around) which are perfect, to crosses you can draw on walls, to furtiture (that actually helps as it has form and colours a scanner can corellate). Of course this means setup, and time consuming. This is why you pay money for good scanners that are professionally used, because they accelerate your work and bring you money back. Also by being more precise, you spend less time correcting errors and have a professional work to deliver to your client, or if it's you that are working withe the files, you work with confidence and fast
So long as my models stay on my computer and aren't collected. 3d models are kinda valuable these days. Also wondering if you could use video frames. Say you take a video and pull every 100th frame and use that as a picture. And would like to see how it compares to Googles augmented reality scanner which a lot of phones are capable of using now.

photographed is the ONLY true point of reference. The object's background, OR WHATEVER IT'S RESTING ON in any photo is
irrelevant, since it gets edited out anyway. So... why would anything extra, connected to the main object, be necessary?
Why would having your camera shot conform to an x/y axis, in relation the object's center, be necessary when either x or y is
not a constant? Because the ONLY REQUIRED points of reference are with the object. Anything else is irrelevant.
And, then again... I could be wrong. My apologies if I've missed something.
Thank you taking time & making the effort to post this. Much appreciated.
@@Seemsayin Hi, I am no scientist and I don't know how photogrammetry software really works. The way I understand it is that in a first step the position from where the photos were taken needs to be calculated. That is easier when the object remains stationary, because then the background can also be used for the camera position calculation. But photogrammetry software gets better and better and it could be that its now also possible to have the object aswell as the camera move. As long as the object itself doesn't change.
@@Holocreators Ya see? I knew there was something I was missing. Thanks for your reply.
This is a great video that does an excellent job of demonstrating the two methods of 3D scanning Thanks for the tutorial Swann
Glad it was helpful!
Brilliant! It seems like a lot of work (and it is somewhat), but if you only have needs occasionally for a part that is unavailable or prohibitive in price, this is amazing! Thank You very much, very much!
Thank you for the kind words. Have a wonderful weekend.
Damn this is awesome, now i can 3d print anything i want, i just had this idea of scanning something and converting it to stl 3d model from pics, didnt think this was actually this affordable.
Hi Martin, yes you can. The Scans can look rough sometimes and cutting away unwanted elements just in meshlab can be not enough. Then you should probably also open the scans in blender and do some more cleanup there. But then you can scale it and export and 3d print it. Have a wonderful day. Kind regards. Swann
Amazing tutorial. Thank you! Something I always wanted to try. Keep the vids coming! 👍🏻👏🏻👏🏻
Thanks Jean. :-)
I’m never going to do this, but that was an incredibly well made and informative video, well done 👍

Great video of how to get up and running quickly! I find a lot of other videos bore me, thanks for the great content!
This one isnt boring? I feel like I'm in hs social studies.
Glad you enjoyed!
Great job, very interesting. Good luck for the future
Thank you very much!
Thank you for your effort in this production
My pleasure!
Taking all those photos looks a little tedious. Curious to see if it's possible to record a video instead, then convert the video to a bunch of images and use those instead. I'm impressed at how good the scan turned out 👍
Good point! But make sure its a high resolution video without camera shake or you will not get a good reconstruction. I have tried it.
So a lot of diffused lighting would be good for this.
Yes you need a lot of diffused light for the best possible scan. Light is your friend.
This took my, kinda high end 5 years ago, pc like 2 days to complete. Only just importing to mesh lab. Will update.
curious. but two days seems pretty long
Excellent tutorial, really useful and well done. Thank you and congratulations for the great job!

As my siblings, and I, disposed of the belongings from my parents last house ... I was able to grab an antique (probably early 1900’s) globular, store display, dispensing jar made of glass. Our family over the generations have used this as a cookie jar.
As I was cleaning it, it soon became clear that the cover that now exists was not the cover it originally had. To my best guess the original cover may have been glass, or possibly even a shaped steel sheet. The top of the jar has threads that suggest that it may have gently screwed on.
Yes the worst case scenario is to strip the aluminum cover of its paint and repaint it to match the base of jar (presuming it came with the original jar) but then the threads of the actual jar would still be ignored.
Questions:
Would it be possible to get this jar scanned to both get:
• The essence of these threads for reproduction of a new lid?
• Would it also be possible to get a scan to capture the glass design with the thought to handing the scan to a glass craftsmen to reproduce a likeness it in a new cover?
I am a person with multiple disabilities. The skills needed to produce a new cover for this antique are beyond my skill set. In the past I have tried to contact Minneapolis/St. Paul, Bloomington Minnesota area maker studios and all I have gotten is dead silence. Is there a ‘correct’ way to contact a Maker Studio to connect with a maker who might have the time to work with me on this project? OR is there a company in my area that help with this project?
hello, scanning the threads of the jar is possible with this technique. But you have to take very high resolution images.
The scan will then only be a starting point to analyze the thread pitch.
this will need to be reconstructed inside a cad software to create a new lid.
this new lid can then be 3d printed.
I could do all of this for you, the price would be probably around 300-400 EUR. For a more accurate estimate please send me a picture of the jar and needed lid to info@holocreators.com
@@Holocreators Thank you for a response. Your the first company that has actually made a response to my inquiries. I will send a separate response independently of this channel.
What an excellent video, I have absolutely no need of this tech, it just looked interesting and indeed it was, were I 40-50 years younger I may have had a go at it, well made, well explained, well done.
Thank you very much.
Great video! Would be great to see also some tips and tricks on structured light scanning.
Thanks. Yes I am planning to do a structured light video soon. What kind of tips and tricks are you expecting on that topic? Then I can include that in the next video.
@@Holocreators how to setup with micro dlp projectors and mobile phone for structured light scanning
@@normanonyxdagang7440 That sounds like a fantastic idea. I will look into it. :-)
This is an awesome video! But I have scanned a test model before and I didn't have to combine the top and bottom angles, it combined automatically in Meshroom. I think that's only the 2021/2022 update though. Great video!
Great tip! I didn't know Meshroom had this function. Yea the video is already a little dated.
Btw image size matters
Bigger images better detailed scans
I shoot mainly with 108 MP or upscale 12 mp photos
yes I agree. more pixels more accuracy.
Out of curiosity, at 4:40 when you're scaling your photogrammetry model, why did you calculate a scaling percentage instead of using the "target size" measurement to input your 76.2mm? It seems like that would give you better accuracy, as there's no rounding of the scaling factor. I mean, obviously the results speak for themselves when compared to the professional scan, but I found that step odd.
Hi Andrew, no particular reason, it's just one workflow that worked for me, if "target size" works better, then please use that
Thank you for this clear, concise video!!!
Glad it was helpful!
Thanks for such a great detailed explanation!
Thank you Imad.
I saw your video only today , congratulations , great work I would like to understand how photogrammetry works , I am sure that this video will be useful to me.
Thanks and welcome
Please mention also something about software/hardware compatibility...Mac/Windows, Intel/AMD, Nvidia/whatever else
well, I am sure you'll find that information on the website of the software companies.
I agree - see my comment on the need for an NVIDIA card
@@woodwaker1 I added it to the pinned comment
Great video, straight to the point, no messing around. +1 sub
Thank you, much appreciated.
At 4:58 you use a comma instead of a full stop entering the scaling 10.917. Is that the reason there is an exclamation mark in a triangle box on the right corner of the screen?
Very informative video, thanks.
That was an error when typing it in. But i think the software autocorrected.
The exclamation mark has nothing to do with it though. That is a polygon issue
EXCELLENT video my friend!

I think it is a big minus at Meshroom, the program only runs on specific graphics cards. "Meshroom requires an NVIDIA GPU card with a CUDA compute capability >= 2.0 for the MVS part. "
Hi Per, yes thats unfortunate. You could look into other software for photogrammetry like reality capture.
Something that I think should be mentioned at the beginning is the requirements for hardware. You MUST have a NVIDIA graphics card. I have an I-5 and use internal graphics. After going through all of the steps and starting the conversion I finally figured out that It error ed out in step 7. I can understand that they built the software to use a specific hardware minimum, but many of us do not have it and I don't like wasting a couple of hours to find this out.
[13:49:26.570938][warning] Could not determine number of CUDA cards in this system

Thanks David, I wrote your findings into the pinned comment. I wasn't aware of these hardware requirements.
@@Holocreators Thanks. I'm not even sure what the minimum card would be. It's been a long time since I added a video card to my builds as the internal graphics meet my needs.
@@Holocreators I have tried a number of other "free" programs, and feel that Meshroom looks very good.. I just ordered a refurbished NVIDIA card from NewEgg for $30 to try this out. Thanks for what you did with the video, would be great to update with what the minimum hardware would be to get at least a fair result.
@@woodwaker1 yea correct, can't edit the video though, thats just an amazing amount of work. But I will put it later on the blog
@@Holocreators Thanks. I will let you know how this works. The card I ordered is a GeForce GT 730. I have been doing a lot of research and this card seems to meet the minimum requirements. Here is a link to the minimum hardware from Meshroom. meshroom-manual.readthedocs.io/en/latest/install/requirements/requirements.html
This is nice but easier way is to take photos from top, all sides and bottom and then measure diameter of bottom circle and then make new part in Fusion 360 (non commercial version) then save in stl file format and open and finish editing in FreeCad and save also in STL and then open in slicer.
Yes you are right, but freeform surfaces you will not be able to create this way.
Love what you're doing on this vid, thank you for the candid breakdown.
thank you, very much appreciated
Inefficient placement of the Dyson fan.
haha, thanks. It's my friends. Was quite hot that day in the office ;-)
Clear, detailed and very useful. Big thank you.
thank you
In reverse engineering discipline, it is not very important to be accurate on the surfaces.If there are not drawings(which is assumed,because if they are available, then you can just re-create the part, not need to scan it).And as far as the hole sizes and locations, you can check with caliper and readjust the scan, after you convert it into solid geometry on you CAD program(like SpaceClaim).....This, what you are showing here is very useful information for the industry. Can save a lot of money and time!
Thank you Jiri, I agree when there are no drawings and complicated surfaces then Reverse Engineering is a great technology
Excellent video. Great detail and thank you. Did this video remind anyone else of BCC? lol
Thank you.
Excellent tutorial/info! Thank you for sharing.
thank you :-)
YOU ARE A GOD... NO QUESTION ABOUT IT
Thank you
I find it very interesting, but it is not clear to my why scanning that object is more efficient than rebuilding it from scratch in a cad program. Seems to me that with some proper measurement tools dimensions can be taken more swiftly than doing all these steps as described in this video and the video about making the step or stl file
Hi, really depends on the part. Freeform organic surfaces are really hard to model in cad. But you are right, this particular part you could have properly solely created in CAD. But I guess you came here for the 3d Scanning ;-)
Very good video. Given you have only a Galaxy S6, but get quite amazing photos for indoor shooting, I wonder what the lighting looks like? Seems like proper studio lighting. Can you please tell us more?
Hello, for lighting I used two soft boxes. They make nice even lighting and you can get them on amazon.
Thank you, this will help in replacement parts for my RC planes
Hi, glad it was helpful. Have a great day.
@@unsp0k3nst0ry winds are not much of issue, mostly front cowling and such
It would help to see the scanned models actually printed out.
The part was indeed 3d printed in metal: www.classicindex.eu/images/0_galerie/Technik/3D/Beispiele/Tankgeber_kompl.jpg
could you scan a motorcycle engine with this method? or would this be a too large geometry for the software? the engine does have a lot of unique points so tracking wouldnt be the issue i believe
Hi Thomas. You can scan a motorcylce engine with this technique. But it would probably be not detailed enough. Especiall the cooling ribs on the engine block will be difficult to reconstruct.
Hands down one of the most beautiful tutorials I have ever seen. Will this work with organic shapes - i want to do a 3d print of my dog ? Any suggestions ? Thank you :)
hi, thanks for your reply. dogs are notoriously difficult to 3d scan. i have done it before. for that i would recommend a hand 3d scanner. you should search for something like artec 3d scan. once you have the file 3d printing is easy. any 3d printing company can do it, i always like to use shapeways
@@Holocreators thank you so much. Unfortunately the prices of this company are way way way out of my budget - i mean 13 - 14 K euro. Thats spicy. Thank you and all the best

I have a plastic part for a car I need replaced. It is no longer available new or used. It is the cover for the electric power seat controls. I have one in good condition, I need the one for the other side which is a mirror of the one I have. Can the one I have be scanned, then mirrored and then 3d printed? If so, who can do it for me as I have no intention of getting a 3D printer and being on the ATF watchlist...
You can't get a 3d printer when being on an ATF watchlist? Thats wild. But to answer your question. We can 3d scan your car part, mirror it and send you the files or 3d print it for your. Please send me an email to info@holocreators.com
Thankyou! Straight forward and to the point! Excellent tutorial :)
happy it helped
Excellent video. It looks like picture-taking (200 pics in your case) is no doubt one of the longest processes in this project- would it be possible to use the Burst function on my iphone camera and use a slow sweeping motion (instead of incremental as you're demonstrating) to make the process a little faster? This should also allow taking of more pics for a better dataset. Of course, all of this is null if the pics are fuzzy. If one found themselves doing this on a repeated basis, a jig is in order- may be my next project :)
Hello and thank you. I think the burst function should also work. Just check the pictures afterwards so they are alle in focus and not blurry. Kind regards. Swann
Thanks Swann. Looks like someone had the same idea: th-cam.com/video/m7ee4jLk_As/w-d-xo.html
@@tallcypress I'd avoid the burst function. With photogrammetry you rely on the sharpness of the images. To get perfect results a tripod and shooting one photo at a time is what i recommend.
A turn table is often used to help with this. A steady tripod will also help to keep the distances similar. Then you can lock the focus on the camera so that things stay in focus. You'll probably find that taking pictures from further away helps things stay in focus better, especially with a good camera and a telephoto lens, since the differences of height on the details of the part will be small compared to the distance between the part and the camera, so it will remain in the depth of focus. If you have a decent DSLR camera, you can also use timed exposures or a simple remote to take pictures at regular intervals as you turn the part.
I am a dentist looking something which I can use as intraoral scaner does my cell phone can replace it
good morning, I dont think this could replace a dental scanner. Inside the mouth there is little room to do photogrammetry. Maybe if you had a very small camera, you could give it a try though.
Can these be transfered to sketch up. I do stereos and would like to be able to scan trunks so I can build boxes to fit tighter
when you install an extra plugin for sketchfab you should be able to import obj files into it. obj is the file format in which meshroom exports the files
@@Holocreators thanks for the response, now I have to try it
Can you recommend another method of scaling now that Autodesk killed Netfabb basic?
Hi, is the old version not working any more? github.com/3DprintFIT/netfabb-basic-download/releases
Couldn't you add a reference object to the scan? like a gaugeblock sitting right beside it.
Yes you can. Great idea. I'll do it next time.
@@Holocreators something i saw online on someone's setup is that they lined the base of the box with newspaper
@@Casey-tm6tv Thank you, this could help with the registration of the images. also you should always place a ruler in the scan to make scaling easier later on
Would the phone scan be better with the latest multi lens phones? What is the driver, picture resolution?
newer phones have better cameras so yea the quality will improve, for best quality always use dslr cameras
Would a small welder's turntable, a tripod, some lights and an object of known size at known distance make this even better?
Yes you could get a better result that way. But make sure to have an even background then. Like a grey screen. Otherwise the photogrammetry software (meshroom) will be confused because the object in front is turning but not the details in the background!
@@Holocreators thanks for the reply, i'm off to the store to buy some of the greenest fabric available...
I have some experience in studio photography and fabrication, trying to get into 3d modeling and printing on my own. This would help a lot.
@@mindbreak666 It doesn't have to be green. Dark grey is good too.
Could you make a bigger yellow plate or "Studio-green" - and remove that in photoshop, and then dont need to 3d-scratch that off later on, so you only have the core object ?
Hi Torben, yes that is be possible. You would need to post process (mask) the pictures then.
Do the red dots and crosses all over the object have any meaning in the scanning process? Is it easier for Meshroom having these specific markings?
Putting targets or markers on the object can result in a better scan. But its not guaranteed.
I'm a senior 3d modeler. not sure how useful are those 3d scanners right now, but i can model a cleaner piece of 3d model using my 3d modeling software than the results that you are showing in about 1/4 of the time.
thank you for your input
I had a Galaxy Note 10 which had a ToF sensor (time of flight, similar to a Lidar scanner) , imagine the possibilities if that ToF became mainstream on smartphones
it will take only a short time i think
Have you tried Lidar on newer iPhones or iPads?
yes LIDAR works great, especially for larger parts. This tutorial will work with photos only.
Just brilliant! I tried to scan my all black and shiny Earphones but at the first time it didnt worked at all. But a simple trick made a huge difference. I created a thin layer of flour around it and everything just worked fine. Now I can create my own ear hooks without spending an insane amount of money on Apple Beats. :D
Thank you for your tutorial. (Danke Digger!).
Maybe you can give this advice to noobs like me for the next tutorial of that matter. (:
Thank you. I happy that this worked for you. Flour is a great idea, I tend recommend a specialized scanning spray also.
Amazing tutorial, it at least let me know that I can keep using Meshroom and save money for better PC hardware.
Even though 3DF Zephyr's price is still tempting.
i use meshroom to this day as my default 3d viewer. its so versatile.
Great Great Great Content and video !!!! ❤️❤️❤️
thank you
hello, when I use meshroom, I get an error on the second node called feature extraction. and it seems to stop the whole process after that... what do I do???
Could be that you have the incorrect graphics card in your system. I think it needs to be an nvidea chip.
Awesome tutorial! Loved the presentation style! I wonder if there`s any free or low budget combo i could arrange to improve precision and use this workflow you showcased for GD&T purposes.
Hi Ralph, sorry I don't know how to help you there.
I've tried this method, but for me it wasnt very successfull. I have gotten an old car plastic part which i wanted to scan with meshroom, it did, but because of the part is black, the images doesnt give back the true geometry when its processed by meshroom, i tried painting it yellow or something brighter, but that only solved some of the problem. Do you have any recommendations how could i improve my scanning or the results?(after the meshroom process some part of the plastic is missing, i dont know why).
Paint contrasting dots all over it and rescan. It works for Hollywood
I agree with the horse ;-) . Paint it bright white and add tracking markers. Also the object needs to be well lit so the scanning works well. Use diffuse lighting like in my video please.
Thanks for the great info.
2 questions
1) Can you suggest any similar workflow for a Model wearing a dress.
2) which software is used for the final slow motion rotation of product.
Awaiting reply
Thanks for all.
Hi, with a dress it can be much more difficult depending on the fabric, just give it a try. unfortunately I don't remember the software anymore i did the rotation with, almost 2 years ago ;-) but Freecad can do such turntable animations. you just let it turn and run a screen recording tool (OBS) at the same time.

Hello I need to create my own characters in scale HO (1:87) Can I scan a person with this technology? and How I reduce to scale 1:82 in the software? thanks
Hi, just4funtrains, yes you can scan a person with this process, if the person holds really still. Please check this video at 4:10 I explain how to do rescaling. Kind regards- Swann
can you also export as an xlm or can you convert stl to xlm? would be cool to open the scans in maya or blender for 3d modelling
or in unity
Hi, meshroom provides the files in the format OBJ. Obj can easily be imported into maya or blender. 3dxlm is a dassault systems file format. so you might be able to convert the obj to an stl. then import that stl to solidworks which is a dassault systems product and maybe from there you can do the export to 3dxlm.

What I'd like to know is how to do accurate room-scale 3D scanning (scanning the interior of a room or series of rooms) without having to spend thousands on a specialized device like Leica or Matterport.
I got an occipital structure sensor for a few hundred, but the quality I'm lookin for just isn't there. The deviation error can be up to a full inch off, and the iPad memory limits you to about 15 seconds of scanning time before maxing out.
Photogrammetry is not so well suited for room scanning. It can be done, with many individual scans stitched together but its a lot of work. I would highly advise to rent a laser scanner for this task. In Germany you can rent a Faro Focus 70 for 200EUR for one day. Thats enough time to scan an entire house from the inside and the data quality is superb.
Well scanning rooms is very difficult, specially in a precise way, since you have to be at multiple distances from the object, and there is little to reference it (like plane wall with no detail). If you try adding markers that appear in multiple images, it will be easier for the software to produce a good model. Markers can be anything from precise dots (white inside, black around) which are perfect, to crosses you can draw on walls, to furtiture (that actually helps as it has form and colours a scanner can corellate). Of course this means setup, and time consuming. This is why you pay money for good scanners that are professionally used, because they accelerate your work and bring you money back. Also by being more precise, you spend less time correcting errors and have a professional work to deliver to your client, or if it's you that are working withe the files, you work with confidence and fast
@@luisfilipelopes2900 I absolutely agree with Luis

So long as my models stay on my computer and aren't collected. 3d models are kinda valuable these days. Also wondering if you could use video frames. Say you take a video and pull every 100th frame and use that as a picture.
And would like to see how it compares to Googles augmented reality scanner which a lot of phones are capable of using now.
Yes you can also do photogrammetry from video frames. But I would recommend taking still photos. Much better quality.
