In this video I present my photogrammetry setup I use for indoor 3D props scanning.
My intention was to show not just what, but also why I use certain things.
I want you to learn from mistakes I made while building this setup so you can learn from them and build a better one.
I really hope this will give you get better understanding of camera setting, light behaviour and Depth of Field dependencies so you can use them in your advantage.
In details I show:
- inverse square rule for the light falloff
- Depth of Field dependencies
- short story of failures, lessons learnt and improvements introduced to make this setup working
- complete list of photogrammetry setup for 3D prop scanning
- how to finally connect everything together to start the scanning process
Since its a long one, I really hope it was worth the effort and someone finds it useful and helpful.
If you like it and want to see even more content like this one, please subscribe to my channel and leave the thumbs up.
Big thanks who did it already as it really helps me to move forward.
Stay safe and till the next one
Cheers!

One of the greatest tutorials I have ever seen. Didn’t even realize how long I was watching until it ended. Thank you keep up the good work
Thank you Leo, very appreciated
Hell yes,, this guy is a wizard
The BEST tutorial video I've ever watched!
THIS VIDEO IS RICH!
thank you

Blender guru put this video in his weekly emails
Omg, so coool. Didnt know. I am his big fan tho, this guy is awesome and has amazing talent to share his knowledge. His donut was the first thing I ever made in Blender :)
@@GrzegorzBaranArt Awesome!
Get this man a donut

Superheroes exist and they live among us.
Great video, and such a huge effort! Now you're a known pioneer of photogrammetry. Many thanks for making this content public! :)
Thank you for such kind words
Brilliant job, thanks for including the wrong decisions you made as well, this helps to realise we are all human :)
Thanks John, yeah, mistakes are usually the best way to learn, unfortunately the most expensive one too ;)
It also helps us NOT to buy the cheaper version of things that we think we might be able to get away with
Best tutorial I have seen!

BIG THANK YOU
very helpful video. very well and thoroughly explained.
Thanks, doing my best :D
I love your scientific approach to the subject
Cheers!
amazing... very thorough great job

Amazing video, thanks a lot.
Hey Timo! Big thanks
blender guru andrew price suggest me through me his newsletter....
awesome content sir...
subscribed your channel...
thank you sir for this amazing tutorial
hey, I am very happy to know you've found something useful in here .. and welcome to my channel :)
Thank you, amazing explanation. Lot's of people saying it's not possible to to photogrammetry without reference in the background - finally someone who can properly explain why this is mis-information and how to do it.
Thanks :)
This is a very honest video. You described all of your mistakes. Thanks for that. I am now trying to copy your setup.
Thank you and good luck. There is one thing I have changed since this time I made this video. I purchased even better remote flash transmitter - the one which supports TTL. It doesnt change much for this setup but it does when you ever use any Flash with TTL.. so for example if you plan to use part of this setup for Photometric Stereo and use the AD200 flash light as a source of light. SO basically I ended up wih the: PRO ST-III Plus 2.4GHz TTL Flash Trigger with High-Speed Sync & Bluetooth (X2T)
@@GrzegorzBaranArt Thank you very much. I've set up everything here provisionally and take pictures with my mobile phone in RAW format on a turntable. Next, I'll buy the camera and a lens. I also bought a tutorial on photogrammetry. But your video is better suited for studio recording.
Love it, I can't afford to get into this currently but glad you are here to share the topic. Thank you!
Thanks, bear in mind that it took me a few years to build this setup, so just be patient and purchase gear one by one picking those you need the most. So I guess.. camera first.. lens.. color checker.. tripod etc. Also its just the option, knowledge is the most important in here as allows you to adjust the workflow to the setup you have. If you know all 'why's you can scan even with you mobile. Cheers!
BIG THANK to you! Your videos are very well done and they should appear on Artstation learning and 80.lv.
Big thank to you too, trying to do my best and put as much effort as I only can to each one .. yeah.. would be great if they are shared.
Feel free to share links to them :) as every single share is a big help for this channel and helps it to grow.
WOW this video is Amazing. Well made!!
Thank you Bjorn, very appreciated
Great video. That said the software side of things might be the more problematic topic.
Thanks, no worries. Going to cover 'software' side next time :). Still not sure should I cover reconstruction process and automasking in a separate video or do quick preview in the one I am planning to make to cover atlas textures tho. Different apps have slightly different tools for automasking but if you know how it works its quite easy if the capture was well done.
Thank you so much for this detailed and complete guide!
You are welcome. I am really happy to know so many of you found here something useful :). Cheers!
Niesamowicie inspirujące, dziękuję! :)

I got on my own as far as camera, lens, software, small tripod, and realized I needed a turntable for the small things I want to do. This just filled in ALL the blanks I would have had to fight through to do the smaller things I want to try that are not nature. Nice.........
Glad to hear that. A good turntable can make the job much easier :)
Wow! you went through a lot, but the results were worth it
Genialne! Prawdziwe kompendium wiedzy. Ten film to czyste złoto. Widząc twoje zmagania z materią -polecam zainteresowac sie kupnem drukarki 3d. Np Ender 3 v2 - tania jak barszcz, a otwiera drogę do tworzenia tysiecy przydatnych narzędzi. // Epic! A real compendium of knowledge. This movie is pure gold. Seeing your struggles with the matter - I recommend that you buy a 3d printer. Eg Ender 3 v2 - dirt cheap, and opens the way to the creation of thousands of useful tools.
Dzieki wielkie :) Najpierw musze uzbierac na drukarke a mam jeszcze kilka projektow przez soba, ktore chce pchnac w pierwszej kolejnosci a moga mnie one sporo kosztowac.
great work, as always. onkly thing i would add, is to always try to extend centre column on the tripod as less as possible, since you only adding vibrations to the camera . i know it come handy, but stiil. your tripod is already probably on weak side with all stuff on top. but then again,, exposure times is short enough that shake is not intruduced..
Yeah, with the flash and such short exposure time all vibrations get frozen and never were the issue, especially that the capture is fully automated so I dont walk around adding additional floor vibration. Vibration become an issue with LED light being used or with significantly increased magnification levels. In this case the solution is to add more delay time between each shots to let camera calm down (optionally use electronic shutter with the LED light so we dont get any vibrations from the shutter movement).
Absolutely brilliant content! I’m sure I’ll be reviewing what you thought us soon. It was so easy to hit the subscribe button. Cheers for sharing

Cheers Daniel!
Great video! I love how you keep refining the process to streamline it. Would love to see more on substance designer towards the end.
Thanks Mike, appreciated :). Regarding the Substance part.. that was the plan since the beginning but after I found the video is one hour long I decided to split it into two parts.. one about prop scanning and the other one about scan usage. In the next one than I am going to present how to turn these scans easily into high quality atlas texture sets and how to scatter them across already existing materials but even how to create a totally brand new ones. I was researching this subject since months too and have got very promissing results.. which I am planning to share soon :). This is why I just mentioned this at the end of the video instead of turning it into a 1.5 hours long one :)
Cheers!
Great in depth video. Loving the MacGyver fixes you've come up with and hats off for showing your mistakes and learning process.

excellent tutorial as always, and what a ride, several months and hundrets of dollars later, i guess learning by burning holds true.
ever thought about buying a 3d printer ? this would propably save you a lot of money and open up a lot more possibilities, like printing the magnetic polirization holder yourself, or printing your prop holders instead of using toilet paper rolls
anyway, nice work !
Thanks a lot. Yeah, I was thinking about the printer but since company or corporation I have a very limited budget to spend on my research and have to prioritise things. The 3D printer is in queue of stuff to get at some point .. but there is still a few things I want to cover first.. dont wanna spoil it though :). Regarding the toilet paper .. .. finally I decided to use the alluminium foil cardboard roll ;P

Amazing video.
I'm excited to learn how you process your scanned 3D objects.
How do you create roughness maps for example. I hope we will get a workflow video soon.
Keep up the good work!
Thanks. This one is an example of how I used scans, created and modified roughness: th-cam.com/video/5rB7pqPXxSE/w-d-xo.html
I turned them into an Atlas texture and used this texture to generate material of ploughed earth :). I also presented details of how I created roughness using Substance Designer in one of my previous videos about surface.. it was the one about sand as far as I remember.
this is a great video ty for taking the time and effort to help others.

muchas gracias, muy bien explicado , muy completo
De nada, feliz de saber que :)
I wanted to scan something. I saw this video. I left the project. Besides that, it's a great tutorial.
Sorry to hear that Andrei, please dont give up. There are easier and cheaper ways to scan stuff which should be fine if you are fine with the lower level of output quality. I just presented workflow that guarantees top quality and shared experience and lessons learnt during my research. My aim wasnt to discourage anyone but rather help to understand all 'HOWs' and 'WHYs' those who want to give it a try or struggle trying.
@@GrzegorzBaranArt you did a great job. That was the best tutorial on scanning i have seen. One again, thanks for the video

You are welcome
Fantastic educational video, presented with style!
Thank you :)
Wow, we built a scanner at our Makerspace ourselves using the OpenScan System with a stepper motor and a turntable from Ikea which can hold quite a bit of weight. I still had always problems with the lighting. I never thought to use a ring light since we built the lights ourselves. Great job and amazing walkthrough!
Yeah, the light is definitelly a tricky subject and needs some calculations and supportive camera setting. This is why I suggested to shot a few test images before to make sure that we utilise dynamic range properly. And big thanks for kind words.. very appreciated :)
If your stepper motor and turntable from IKEA ends up being too small or not accurate enough, Iconasys has different size and capacity software-controlled photography turntables. iconasys.com/applications/photogrammetry-3d-models
Great work 👍😊
Thank you Peter
That was a fascinating video. I watched the whole thing from start to finish. Your use of ring flash to illuminate your subjects is something that had not occurred to me. Managing to keep the subject properly centred and securely held in place can be very time consuming. Working out the best way to maximise the available depth of field is another task that consumes a lot of my time when engaging in photogrammetry. Once all that is figured out, taking the photos themselves is fairly straightforward.
Cheers, hope this video was helpful to improve your photogrammetry workflow :)
Video nice
Cheers!
Awesome
Cheers!
Very good video!!!
Thank you Alexandre :)
Bravo, really enjoyed your journey with this project 👍
Glad to hear that
One thing I'd say is - don't be afraid to use full-frame cameras. I've tried with both sensor types and the full-frame cameras having physically bigger photosites is a big advantage in both lower noise and overall sharper image.
Also even something as old as the original Canon EOS 5D works very well if you have enough light and a sharp lens on it - I've done 3D scanning that way too with fantastic end results (I have a couple of those as just "banger" cameras to carry around for daily walk purposes). High resolution cameras help with more getting more detail, but that mostly applies to scanning very large objects (such as buildings), since with small objects you're likely to have way more resolution across all the angles than you'd realistically need anyway.
I think its not that simple. I used both cameras and currently I use a full frame one. Smaller sensor isnt always a disadvantage and has nothing with noise level in controlled lighting conditions. Smaller sensor usually offers higher physical resolution per same focal length. Since smaller sensor captures cropped image, it also get rid of all these side distortions like perspective one, or vignetting, which can be very significant if you dont use a very expensive and fancy lens and shot in wider focal lenght. These are noticeable when we deal with kit lenses.. I tested these but havent make a video about that yet.
So cropped sensor and full frame sensor are totally fine for purpose of props capture. Since full frame is simply physically larger, it allows more light to get in proportionally - but it matters in limited light conditions really which isnt really the case here.
Regardign image resolution: you are right that larger resolution is better as it allows us to capture more information per image. But in practice, more images under different angles are always better to less images but in higher resolution. So the choice between crop and full frame sensor isnt as obvious and if you deal with small subjects in controlled, indoor lighting environment, the crop sensor is a better solution. Full frame is a better for outdoor captures. I would say that in both cases, its really the lens which seems to be more important here, not the actual, physical sensor size.
So in my opinion, both: full frame and cropped one are fine.
Last but not least, images captured with high resolution cameras might very easily become a bottleneck for photogrammetry reconstruction - due to memory constraints and processing time. So for example, when I use a Sony A7R4 camera even with SONYs high quality flag lenses, I still dont use its full resolution 60Mpx matrix in full frame mode, but I use the cropped mode instead.
Ever tried reality capture? I used to work in metashape but it was just so slow. With reality capture i can align the images in less than 3min and do a 200mil poly mesh in an hour.
The only downside is that its perpetual licence is very expensive. But i convinced my boss to buy it and i'm using it for everything now.
Yes I did but not for private use. Reality Capture was way to expensive for me and I never was a big fan of subscription model they offered. I purchased the Metashape 5 years ago for 130USD and I still use it while getting all updates for free. As far as I know Reality Capture is still faster but not as much as it used to. Also reconstruction quality is totally comparable between RC and Metashape, not mentioning improved resource management so the Metashape doesnt need super strong PC anymore.
Regarding image alignment.. you can also align images in 3 minutes with the Metashape, it depends on the setting you chose and amount of images used.
I am working on a comparison video where I compare Reality Capture, Metashape, 3DF Zephyr and Meshroom since about a year. To be honest.. one of initial reasons I built the setup which is the subject of this video was to scan some props I can use in this comparison :). I might never finish this video tho as this is not the only one I am working on since over a year. Another one is the one which covers Photometric Stereo reconstruction.. its also an ongoing one :).
@@GrzegorzBaranArt Oh, you're aligning images in 3min? strange, i have to wait 10min for "matching points" and half an hour for "camera locations". i'm trying to align 300 cameras with the highest alignment settings and 80,000 points, and it's a model scan not a texture scan, maybe that's the problem.
What are your alignment settings?
Also would love to see that comparison video!
@@jvolto Not at all.. every software moves forward.. as I mentioned Metashape has changed a lot recently. And of course a lot depends on setting used. You can set the amount of points to 40million and it will take hours. But if you do that with the RC the result will be exactly the same.
Anyway, just for you I took the scan of the small soil lump you can see on this video when I talk about the dirt sitting on the platform. It was captured with 174 RAW images in 24Mpx and I processed directly these RAW files without any postprocessing. For reconstruction I used Metashape 1.7.2. I didnt mask any images. I used default high quality setting for the alignment with generic preselection active and default key point setting:
Accuracy: Highest
Key Point Limit: 40,000
Tie point limit: 4000
The full alignment took 2mins 32secs
But to compare I grabbed 3DF Zephyr Lite in version 5.019 and I processed the same images there with General setting with everything set by default. The image alignment took there
2 mins 12 secs
I used the PC config described in my video about bakers.. so nothing fancy. Hope that helps :)
thanks!
You are welcome :)
Thanks!
Thank you :)
excellent video with some great tips, should have subscribed ages ago ;-)
Thank you and welcome to my channel then :)
Thanks for video ^_^
Hey Alex, you are welcome :)
Great video! Instead of the Syrp Genie Mini one could also buy a Orangemonkie Foldio360. It's not battery powered. It can carry 5kg instead of 4kg and also has an app with the similar settings. It can trigger your camera remotely via infrared, but you need a simple IR extender because the flash light blocks the signal.
Mounting clams to it unfortunately won't be possible.
Big thanks. 'Orangemonkie Foldio360' looks interesting. I was considering different turntables but unfortunately didn't see this one. Big thanks for sharing, definitelly worth to consider as its way cheapper.
Iconasys makes nice software controlled photography turntables that sync with a DSLR camera too. (0.7kg-227kg) It automates the capture process and makes getting hundreds and hundreds of images super eays. iconasys.com/360-product-photography-turntables-and-software
This is a awesome tutorial.
I was wondering, can you do a tutorial on camera you reccomend for 3d prop? I'm going to start learning . Wondered what you reccomend though for out door shooting for 3d props?
Thanks :), I have something like this on my 'to do' list but for now I would suggest to watch some of my previous videos.
