Hi
I’m setting up a body scanner with 50 cameras (canon T6 18-55mm), 10 towers with 5 cameras each tower, but I’m not getting good results. I am taking the photos indoors (lens at 18mm) without having a uniform background (capturing some furniture). what would be the best way for me to get good results?
thank you
Dear Tuqbatera, I di a research on photogrammetric volume for making a full body reconstruction, my advice is that you use at least 150 cameras depends on how fine you want to have your reconstruction. for example I construct a volum of 100 camera s and still I had holes on top of the head , at the section of the underpants the legs. the tips of the hands were not great. I coul show you some examples if you wish.
show me please
Hello,
you can find some showcases of full-body scan rigs also on our website or YouTube channel, for example:

whish is great and somehow pretty expensive, there are so many projects out there:

Never forget you need at least 80% of the same images of the body in order to be able to reconstruct almost perfectly an entire body. And if uou have the money you need more camera for the faces and the hands. so you could put 50 cameras of 50 mpx only for the face and the head. You can also use a telephoto or zoom to get more precise details of the face.
You can see that if there is not enough camera on top you will get holes.
this is the structure i’m doing, but it’s 3 cameras up and two down, monday I’ll start calling and start testing
My two cents, 50 cameras is not enough. We made a rig with 60 and it was the bare minimum, it worked but there was banding due to low overlap. 80 is realistically where you would really want to start and then the sky’s the limit from there. I would also suggest not to angle your cameras when using so few. Just aim for good over lap.
Just try this, take a first exposure have your model turn 35 degree o the left or to the right in the exact same position and expression you will have 100 cameras. Try to reconstruct a cloud point. It might not be exactly precise , but it might you see a full body that will help you imagine what you could get with 100 cameras. If it works you could have your model on a turntable and do it three times or four times. https://www.iconasys.com/360-product-photography-turntables-and-software/platinum-series-xl-360-photography-turntable/
That’s not the way to do full scan body but that’s how you could try to with less cameras
