My grandfather was a photogrammetrist back in the 60's until he retired in the late 80's, He died when I was young but it's amazing to think that he spent half his life working with the same mathematic formulas they use for measuring photos to print models in this video lol
This is unreal technology. Going to be using this for scanning objects for my college game project. Can’t thank you enough for showing this.

Very helpful thanks
You prolly dont care at all but does anybody know of a trick to get back into an instagram account?
I stupidly forgot the login password. I appreciate any assistance you can give me.
This is by far the best video about meshroom. There are tips here that Google has a hard time finding. I am impressed.
Awesome, i know exactly where that first statue is, one of my favourite spots in Prague. I go to the cafe in the National gallery and that restaurant to the right all the time :)
Awesome video. I am loving photogrammetry. My favourite hobby and will definitely give meshroom a try
Woooo... I just discovered last month!!! Awesome software!!!
Thank you for the video. I was new to the topic and tried to read up on it, but your video was just perfect to get into it. Especially the hint that you can make ideal photos on cloudy days has helped - on cloudy days it is not lacking here with me anyway...
Awesome video! Would be nice if you do a live tutorial on 3d reconstruction of more problematic objects, like ones with shiny and flat surfaces without texture. I.e. like reverse engineering old injection molded parts with glossy surface and flat color, or something like this.
Thank you for making this photogrammetry tutorial. Very informative and helped me.
this looks very promising, can't wait to try it out this weekend!
Did you try it out!! Just curious
Awesome work. Great tips and I can vouch for many of your tips from my own experience getting Meshroom finally working this week.
Thanks! Will try the software again sometime.
Great video!! Thanks for introducing Meshroom to us and a tutorial on how to use it for photogrammetry :) I was going to start doing this soon with Autodesk ReCap, but this might be a good alternative as well.
so good for new beginners! thank you!
This is going to be awesome for my 40k conversion projects
great video. i always use photogrammetry but now also use projected light scanning. but the texture maps is the main reason for photogrammetry.
Awesome, thank you for your great work!
Excellent - very much worth a visit.re-visit! Thanks!
Just as usual, beautiful video, incredibly made
imagine drone preprogrammed photo sequence shots. you can get some nice details of sculptures now.
I did this with a local cathedral (with permission, of course). My results then weren't great however, so I may have to try reprocessing the images with this software.
I'd imagine a cathedral with all it's arches and stuff would also be a very complex model to photogrammetry.
*+Acerbjorn* - Look up "Lofotkatedralen", it's not the gothic type :p
There is a Litchi software for DJI drones that can do that. You just set the waypoints and camera angle and it should work (but be careful if you use that)
@@logitech4873 you either need a better camera or fly closer. If you used Photoscan or even RealityCapture, you will not see improvements in other software.
Very cool. thank you for letting us know about this program. I've not been super happy with photogrammetry since 123d Catch was taken down and this looks like it may get me back in to it again!
It has advantages, but also disadvantages. This is why we combine different scanning techniques for perfect results. Great video and great progress in the software!
What other scanning techniques do you normally use?
@@mageenderman Well, I dont work with photogrammetry, but I have read that they also use laser scanning. Its the most precise way to scan a object and the results are outstanding. Here is a video by Konami scanning Schalke 04 stadium and showing previews from the game: th-cam.com/video/qAkUF4Kbgxk/w-d-xo.html
This makes me excited to try photogrammetry again.
Me Too... Absolutely!!
Thanks for explaining this. I have Meshroom already but hadn’t got it working properly yet.
Thanks a lot it's exactly what i was looking for.
This reminds me of the "Building Rome in A Day". Great video! :)
This is the most amazing thing I've seen in at least 24 days. Now I don't know if I want to 3d print something or put it in Unity... or whether I want to mod my house into GTA5... or build a rig that automatically rotates the camera around an object.
how can u make mod for gta from 3d file?
@@talharoxen you mean putting the 3d model into GTA? You use the mod tools, I forget which one you use to export to rockstar format but it should be easy to find.
There's 5 or so tools in total that help you mod, it's not as easy as a Bethesda game but it's not that hard thanks to lots of documentation and community support.
@@polydynamix7521 Thanks. I will try to find them. always wanted to make and mod cars in gta
Great vid - this gets at what 3D printing is really useful for - graduating beyond Thingiverse downloads.
Thanks for updating this :-)
Oh wow, I've recognized the accent and the statue of Dvorak, then I found the video about your printing farm. Great job you're doing there! I wish I could visit the farm one day and film interview with you!
you're asking basically the daddy of the whole maker scene for an interview :-) he's a legend for sure...
great video for more advanced scanning!
Thank you very much for your review!
Best photogrammetry tutorial
This is awesome. Planning on getting a prusa very soon.
Great video! well explained and easy to follow. I want to know if you recommend this software to process aerial images, like the ones taken with a drone. I know there are other options, but I want to know if you know about some project using Meshroom with aerial images.
Holy cow that is awesome!
What a time to be alive!
This was very good explanation of the mesh program I definitely give it a try since it has been updated.
Can't wait to play with this! Can I create 3d assets for use in Blender by exporting the resulting mesh and a UV maps texture image?
Nice video👌🏽 What about making a 3D scan of a part that you wish to have in real life size? Also can those 3D scans be used with other programs to edit the scan or ad additional shapes? And what 3D printing program would you recommend to be used for a good quality print?
this is Awesome thank you for taking the time to make this video
Buen tutorial, didactivo y claro al explicar!
Amazing. Thanks for sharing. Just looking for something like this.
Thanks Josef always sharing your knowledge ;D !
Dannng thoses shoot, so pleasant to watch
TIP for photogrammetry 3 tutorial - about making whole model of the object - including a bottom (or sole).
If it's a small object you could use armature wire to hold it up so that you could see under it. In any case, try to put the model on a base that is smaller than the model.
Love this !
Awesome, will have to give this a try soon. Great work guys
4:19 - the main thing I learned was that you can graffiti bushes! 😂
Great vid thanks! I'm trying it out now! 😃
Thanks for this tutorial. I will give it a try
Have fun! Once you try it, you'll see photogrammetry opportunities everywhere :)
Thank you for this tutorial!!!
I look forward to prusa’s insight on the new iPhone lidar capability to do this
Great video! Just a small correction: Wikipedia is another website. Many sites have wikis, but Wikipedia is something else. 😉
The live reconstruction might be fun if you have some sort of file syncing tool. Take pictures on your phone and have the model already processing by the time you get home.
Would this work with a water fountain?
Or will the water movement spoil the end image?
Anyway great technology!!
Thank you Jo
Going to scan my MK3 and print out a pocket sized version. :P
how did it turn out?
why not just print a new one
This looks really cool
Awesome video, very informative
It was amazing!
How well explained! Subscribed..I would like to see a next video with a drone capture of an urban space.
Love it!
Joseph I really admire all of your work. Do you know of any convincing articles on the market/need for photogrammetry that I can share with colleagues to help them understand the potential demand for this technology? Some of it's potential is understood by your subscribers, but it seems sometimes people need to read a higher-level article in HBR or something like that to appreciate it's importance and potential. Also the art of manual re-meshing is an important topic. Have you covered that in other videos?
Note: Always take note of what focal length you're shooting at - take not of what lens, focal length, camera type and settings you're using. If your scan comes out wrong it can help you when having to enter metadata manually if a problem occurs. It's especially important to make a note if you're using a smart phone camera because often vital data such as focal length is not recorded in the metadata - which is some cases makes the pictures unusable if you can't figure out the focal length and enter it manually.
I can strongly recommend people using the following trick: Import the photos into a program like Photoshop or GIMP and add a mask around your object removing detail in the background. You can also zoom in if you couldn't get close enough to the object in the first place. Remember to retain all metadata while exporting your photos.
Thank you!
Great Video,Thankyou..
Wow, uprime videl sem thumb asi pred 3 tydnama nebo kdy a az ted sem se k tomu zase nahodne dostal a koukam ono to ma pres mega sheldnuti a je to cech :D ... no nic, tohle pokud se mi vysledek podari dostat az do UE4 tak to bude super. Diky moc za info ohledne meshroom!
Hi Josef, would love to see that 3d sculpting episode! (especially with Blender and 3d printing in mind).
Blender 2.8 all the way!
Somedody might suggest a blog, forum or fb channel where to talk about meshroom, and ask suggestions? I tried some attempts but i can't get a mesh done, and I don't know where is the problem:( thanks! This is a very well done video and thanks :)
What if there was a add-on camera the attached to print head to reconstruct an object on the print bed? You already have a machine that can move across the axis.
You place an object on the bed choose scan the printer takes as many pictures as needed then you choose size and print a copy.
Next step x-ray.
I bet you can also take in-game screenshots to effectively "export" asset 3d models from games that dont allow you to access such data.
I tried it and it sucks, game graphics are not that close to reality... :/
@@4WDJUSTY How many shots did you take?
you might be interested in GL Intercept github.com/dtrebilco/glintercept here is one possible application (note this guide is quite outdated): brian-horning.com/google-earth-to-obj-using-glintercept/
I did that with an ingame item from csgo. Worked quite well actually. Used 120 shots or so!
You can also take screen shot of google map (3D buildings) make a model, and sell it for 15 USD (yes some people actually do that)
Better than spending £350 per year for autodesk recap pro subscription! Liked and subbed.
Just when my modelling abilities were starting to improve, this comes along and makes modelling obsolete. I've wasted my life. It is rather cool though. Can't wait to try it!
Hey they're not obsolete! For mechanical parts, CAD is still the best option. And for organic shapes, you'll be really happy to know basic modeling when working with photogrammetry meshes, they almost always need a bit of editing/clean up before printing :)
@@Prusa3D It's good to know I'm not worthless just yet lol. It's funny you should mention CAD, as I recently started using CAD to design machines, and have also sucessfully made game assets from CAD models. All of the metal targets in my FPS game are actually real-world products that I produce. The game models are just slightly reworked CAD models.
i am amazed
I've used PG on old footage from movies or documentaries...
Comparing the models made from old footage with models made of the same scene with newer footage reveals subtle changes in shape.
Besides buildings and construction, it is fun to see a hillside 'heave' during the rainy season and 'shrink' by the end of summer.
Sure, it's only a few feet out of thousands of cubic yards, but is can be measured!
Similar things are seen with Grand Canyon footage; old fly overs and newer ones show lots on interesting 'shifts' in form.
Are volcanologists using this?
Very cool. Thank you
Is there any way to use this technology with an older mac? i have a MacBook Pro (13-inch, 2017, Two Thunderbolt 3 ports)
All Photogrammetry programms ive tried wont work with my system.
Very grateful for any tips, or programms that i could use
Yes meshroom is great! I tried to use meshroom at work to create a reference model of a complex assembly, but management was too stupid to understand why it was necessary. Let's just say the original documentation was useless for building something with thousands of parts. A 3D model of the entire assembly could've been built with photogrammetry in a couple of days, then distributed to every assembler for reference. NASA did something similar for their space craft where they always built two of everything. Photogrammetry is a much more affordable alternative to this.
Great video
Thank you!!
It’s art dude !
Perfect!
AMAZING
Dangit! Im on an Amd Radeon 580 and i cant do this! i hope there is a work around or update that can make it compatible with Amd graphics cards.
I need to try this :) Have you tried a turntable on a white background? Turntable would allow the (easier) use of camerastand and keep the distance and the tilt angle to the object fixed. Combine this with steppermotor on on turning table and you could also get the turning rate controlled. Like 10°per turn.
Non-white background worked better for us, but we've seen some people have success with white bg and a turntable. :) Though the environment was very controlled, strong flash overexposing the white, cross polarizing the light to reduce glare etc. Partially covered at 3:42 -Mikolas
@@Prusa3D Yes, looked further on this and there are methods to make this work using random/uneven pattern on the turntable to help the program on the positioning and having dark background.
Amazing!! Hello from Brazil!
Hi!
the WOW at the beginning though
Glad someone else also loves Dvorak! Got a favorite symphony?
Hi great video! Does the software model match the actual colours seen by eye accurately? And what happens if one photo show the arm to be light red but is slightly darker in another photo because of uneven lighting - how does the software cope with this? I am thinking of using photogrammetry for artwork sculptures, so colour accuracy is a must.
Judging just subjectively by looking at our scans, it does look pretty accurate. If the lighting is somehow uneven, it will get baked into the texture (e.g. part in shadow will have darker color).
However, this is something that you could fix fairly easily. The texture is a normal image file, that you can open in a photo editing program, like Photoshop.
Then you can apply color corrections, if necessary. And de-lighting texture is a very common problem in the computer graphics industry, so there are tons of tutorials and softwares, that handle it - www.gamefromscratch.com/post/2019/07/09/De-LIghter-Free-Texturing-Tool-By-Agisoft.aspx
- Mikolas
@@Prusa3D Many thanks for your reply! I hope to shoot sculptures indoors so to get even lighting will use bounce white lighting off the white walls. This should give me fairly good colour accuracy and consistency in all shots. I hope :) Yeah I use Lightroom and Capture 1 so can colour correct. Thanks again!
Does the EinScan include the colors of the object scanned? Additionally, inside the video, you are showing the size of the STL and OBJ file from the GOlem and Angel, but is that in MB ? or in GB ?
Noob question!!! How can i put a design on a constructed image? I would like to get the 3d design of a motorcycle and play around with colors etc to see how it looks like
Skvělé video :-D
Mám ale problém s tím, že když vložím fotky do meshroomu, ukazuje mi to u nich oranžovou značku s nápisem no camera instrinsic parameters. Už jsem zkusil přidat do databáze camerasensors další objektivy, ale problém přetrvává. Nevíte někdo, jak to opravit? (fotím mobilem xperia x compact)
Nice, thanks!
Yay!!! ❤❤❤😍
Can photogrammetry be used in place of laser scanning for as-built documentation for process facilities?
I wonder is it possible to for meshroom to process a folder of images without drag and drop for different projects
Hello, thank you so much for tutorial. I do have some questions though, and if it's possible some kind of modifications to this model. The issue with my model is that, well, it's a full size mannequin with old ethnological outfit. I need to create a small printed 3D model from the mannequin, something like palm-sized model, using of course the method of photogrammetry, just like you did what that statue of Antonin Dvorak.
I was thinking of placing my DSLR on a tripod and use additional studio lights which are controlled by a trigger from the DSLR. Then, placing the mannequin over a lazy Susan base (made from something more sturdy than a plywood, probably steel lazy Susan), and using the same technique like you - rotating every 10 degrees for a full circle. The background is going to be white canvas (used for photoshoots of real models) made as infinity wall (without a corner behind the mannequin)
My dilemma - is this way of rotating is efficient and reliable? I noticed that you don't recommend rotating the model, but instead rotating the camera. I'm going to use the same light and photo settings, and there aren't any glossy or transparent surfaces. Thank you.
This is just my experience, but I had better luck with rotating the camera, mostly because the camera matching is a lot easier with a few recognizable features in the distance (buildings, in the case Antonin Dvorak).
With lazy Susan, white background and studio lights, you might get very good results too. I did just a few tests with this method, so I don't want to discourage you from trying it just because I didn't get good results.
- Mikolas
@@Prusa3D Cheers, huge thanks for helping me!
I've tried Meshroom because I wanted to do a tutorial on it but I found it complicated and really had trouble getting good results. These days I use Reality Capture. It's not free but pretty cheap.
I’ll have to see if there is an update of Meshroom since I last used it. In Win7 it kept crashing.
Love it.
