Photogrammetry Setup for Indoor 3D Prop Scanning

#photogrammetry #scanning #diy #photography #tutorial #turntable
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!

Love it, I can't afford to get into this currently but glad you are here to share the topic. Thank you!

[@GrzegorzBaranArt]

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!

[@Larry3D]

This is a very honest video. You described all of your mistakes. Thanks for that. I am now trying to copy your setup.

[@GrzegorzBaranArt]

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)

[@Larry3D]

@@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.

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!

[@HDEFMAN1]

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.

[@GrzegorzBaranArt]

[@izoyt]

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..

[@GrzegorzBaranArt]

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).

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!

[@GrzegorzBaranArt]

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 :)

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.

I've learned so much, you're a real pro! Are you excited about being able to use photogrammetry scans in Unreal Engine 5?

[@GrzegorzBaranArt]

Thank you, there are way more usage for scans then nanite systems in U5 but yeah.. thats something that is going to utilise scans better and make them way more common. Anyway, I want to focus on material aspect of them and in my new video I am planning to show how to turn a scanned prop into very high quality atlas texture set but also how to scatter them across already existing surfaces to create different variations of them. This way we can also create totally brand new, scan based materials from scratch :). Not mentioning that scans can be used as alpha stamps in zbrush.. or .. scaterred using physics simulation systems :D

[@grzegorz.lipski]

Great video Grzegorz! I learned a lot of new things from it :D Btw could you say in your opinion what's the minimum focal length for proper scans? I know it depends on many factors but I'm wondering is there a universal lens for indoor prop scanning like 35mm/50mm or better will be zoom?

[@GrzegorzBaranArt]

Thanks Grzegorz. The answer to your question is very complex as it depends on many things which I called in this video DEPTH OF FIELD DEPENDENCIES. This is why I wanted to share basics of it so everyone can make a concious choice while setting the camera for scanning. Basically it depends on the prop size, its complexity/form and its coverage in the cameras frame. Everything after follows it. Technically the closer you are to the subject, the better as you get stronger light, but if the prop is large, deep and complex.. you need to increase the distance to compensate light falloff since as I said in the video it depends on distance multiplication. So there is no the only one setting. This is why I suggest to a zoom lens for prop scanning. But if you ask me about numbers.. I would say that a zoom lens which covers range between 35-70mm would be enough. The soil lumps I scanned were captured with 50mm focal length (cropped sensor), gargoyle 42mm. Hope that answers your questio :D

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 !

[@GrzegorzBaranArt]

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

Brilliant summary! What is the practical lower size limit for subjects captured like this? Is depth of field the primary limitation and, if so, have you tried focus stacking in place of single images?

[@GrzegorzBaranArt]

Omg!!!! Hey Allan, welcome to my channel and veeeeeery big thanks for watching :). Regarding the subjects size limit.. actually there is no size limit and anything that can be captured with the camera as long as we can provide consistent light and if subject has solid enough surface (isnt too reflective or too transparent) can be used for photogrammetry reconstruction. I know that some folks managed to scan some insects in quite decent quality this way already (without image stacking). In theory image sharpness and surface readability are main constraints. So it doesnt matter if we capture a Statue of Liberty or a small insect.. same rules and expectations applies. If something gets out of focus, we simply need to capture a few additional images with each having enough overlapping space for photogrammetry software to find shared orientation points to combine data from coresponding images together. Technically there is no image limit for 3D processing.. we can process even 50.000 images if we want. I guess that focus stacking would complicate the process a lot and would increase overal capture time but if autmated its doable. I am not sure if focus stacking dont mess with actual data and doesnt blur it too much tho as sharpening is a bit fake. To be honest I would avoid focus stacking and rather capture more images from different angles with different focal points. I also believe that light can be a big challenge for micro captures as ring light has quite long minimum workig distance. So it wold probably need to be some kind of ambient light. So regarding the maximum magnification level for photogrammetry... I wouldnt risk shooting with microscopic objectives as the DOF seems to be too shallow and I would rather use a lens where I can push the apreture size to the diffraction's limit getting as long depth of field as possible. With subjects which has irregular shape, auto focus option might be also very useful. So I guess that 1:1 with macro lens is an easy peasy. Even 1:2.5 magnification with macro lens should be totally fine even if definitelly more challenging. I never achieved anything above 1:3 for standard macro lens but I guess that diffraction at this magnification level limits the effective DOF signifficantly and about 1:5 becomes a real issue. Also I have noticed that at magification levels above x2.5 we start seeing individual elemets substances are made of and in most cases they are half transparent and they might not have enough surface features photogrammetry software can use as navigation points for reconstruction, but it depends on an exact surface type. So as far as I know, its challenging but totally possible to scan small insects like wasps or ants in 3D using photogrammetry and get quite decent detail level. But I personally never did that before :) .. not to mention I am still not mentally ready to deal with insects :D.. they scare me. From the other side, it might be very interesting too see how close I can actually go to the subject with the photogrammetry and find out where is the actual limit :). Cheers!

@@GrzegorzBaranArt Hi Grzegorz! Thanks for this exhaustive answer - I didn't see this reply until now and we have made a lot of progress along the same lines you describe. We are also encountering a lot of the same difficulties you outline. Your videos remain a very valuable source of information and your work with textures is groundbreaking. Keep up the good work and if you ever get over your dislike of creepy crawlies, get in touch - I think there are opportunities for collaboration! All the best! Allan

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?

[@GrzegorzBaranArt]

Thanks :), I have something like this on my 'to do' list but for now I would suggest to watch some of my previous videos.
