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
Thank you :)
The quality of content on this channel is off the roof. I am glad people like you exist. Thanks.
Omg.. you've just made my day. Thank you soooooooooo much for kind words. Very, very appreciated
@@GrzegorzBaranArt
www.artstation.com/greenwood070 I followed you on artstation and press liked on pretty much all your tutorial pages. :)
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
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

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 :)
60mn of learning and pur sharing, no crap no usless talk! You are helping me a lot for my future setup....You are the best.
Cheers dude! Appreciated
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.
amazing... very thorough great job
Thanks :)
BIG THANK YOU
very helpful video. very well and thoroughly explained.
Thanks, doing my best :D
Thank you for sharing all this, especially the mistakes. It will prevent so much wasted time, money and resources from being wasted. I will watch this over... and over again. Much respect to you!

Amazing video, thanks a lot.
Hey Timo! Big thanks
Best 3d scanning tutorial out there!
Wow, thanks!
WOW this video is Amazing. Well made!!
Thank you Bjorn, very appreciated
YEESSSSSSS - they sent you a Peanut Slab!! Kiwi confectionery icon!
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 :)
Video nice
Cheers!
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.
All I can say, from the bottom of my heart is ...... GOD BLESS YOU Baran ! Lots of love to you Buddy !♥
This video, above all, was honest ! apart from being categorically informative, tightly cut & very well laid out, sequentially !
Keep up the good work.
Thank you, very appreciated
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!
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! :)

So much value in one video; I just can't believe it. Thank you!
Thank you David, very appreciated
Brilliant! Thank you👍
No problem 👍
I have watched this video at least four different times now.
This is the most accurate tutorial concerning 'void' photogrammetry I have ever seen and honestly, I have been working with photogrammetry since early 2015.
I tend to use standard Metashape as my software of choice, though I do use Meshroom for certain things.
This video is my singular reference when I run into problems or 'scans that don't track correctly'.
Nearly 99% of the time, I find I missed a step presented here, be it filtering alignment or DOF. Also, I tend to lean toward 'I am taking great pictures' vs. I am capturing data.
Truly GREAT video. Please keep the the amazing work!
Your shared work has helped me create some of the best scans I have ever produced.
I thank you for getting me passed some obstacles I just could not wrap my head around.
Thank you so much

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!
many thanks for tutorials , great help :)

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

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: czcams.com/video/5rB7pqPXxSE/video.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 video isn't a tutorial on photogrammetry, it's a complete walkthrough on perservation in the face of technical set backs
Cheers :D

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 :)
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
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 :)
I love videos that tell me what I need is the cheapest lens I can find
But my video doesnt tell that you need the cheapest lens you can find :D. I would rather suggest to get as good lens as you can afford.. just wouldnt be to crazy. Actually I made a comparison of results captured with different lenses and different focal lenghts.. copared one for £300 with the £3000 one.. just never published it. It should be included in my incoming book about photogrammetry though. There is a significant quality difference, but this is not a simple one and depends on many things. Its not always worth to get £3000 lens. Anyway, its a big subject hard to cover in a comment. Cheers!
Fajny filmik dużo wyjaśnia muszę go obejrzeć na dużym ekranie a nie na telefonie :)
Dzieki wielkie :)
Great video! Is it also possible to use the inner circle on the lens (rotated by 90°) when cutting own filter from foil?
I am not sure what you mean. Yes, you can rotate the filter on the lens full 360 degree. Yes you can cut your filter from the polarisation sheet same as I did. The thing is that to get full cross polarisation, one filter needs to be rotated 90 degrees to the other. Thats it. I shared some more details about cross polarisation and fliters in my video where I am trying to recycle polarisatoin sheet from the LED screen: czcams.com/video/A30QPbUPjCw/video.html
and also in my video fully dedicated to polarisation.
Hope that helps :D, CHeers!
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).
Thanks for video ^_^
