I have been trying go make various rinky-dink camera based 3d scanners.
With varied success. The problem is it cant capture anything that moves. (Even a human trying to stand still is not enough)
123D catch works really well, if you do it right the result is incredible.
The problem is the object needs to be stationary. It does not work very well for humans since they move around.http://www.123dapp.com/obj-Catch/Sigurdr/1043522
Therefore, I have been trying to think up a rig to set up multiple cameras in different angles. (Cheaply)
The goal is to arc some pvc-pipes over an area that will allow for a t-posed full grown human to be captured from multiple angles at once.
I have found some really cheap cameras on alibaba, down to 10 dollars (!) per camera if I order in bulk.
The quality is good enough both for generating the mesh and texture.
Since all cameras look exactly identical, I will mount a cardboard plate in front of them with a strong, defined and unique pattern covering everything but the lens. This is also to provide clear and definite reference points for manual correcting.
The cameras in the pvc-arc is not to scale, and was modelled from the specs of a miniature camera.
Connection wize, it seems to be a challenge of usb power, bandwidth,confused drivers and IRQ issues to connect 30+ cameras via USB.
So, that might not be feasible to trigger them all at once.
The cameras in that price range usually do not have any option for remote triggering, so I would have to modify it by soldering all the shutter buttons to one circuit/button that can complete all the individual shutter circuits at once.
My questions have not been answered very well by the manufacturers, nor do I really know how to properly ask how the shutter button circuits work.
My technical english vocabulary is very limited, I am basically wondering how to find out if the shutter buttons usually are simple 2-wire circuits that needs to be closed to trigger the shutter.
I imagine its not a half press button, but if it is, how hard will it be to solder a simpler trigger to all those cameras?
What I mean by half-press, is the cameras where gently pressing the button will focus and fully pressing down will capture a photo.
Does anybody have any good suggestions for the type of solution I can use to trigger cameras like this? The quality
