I am currently working on a research project on 3D scanning (3D scanning of objects) with an Xbox360 camera, do you have any idea about the best mark of the camera?
Artec Micro has up to 10 microns accuracy and 0.029 mm resolution.
it's an ultra-high-precision metrology-grade desktop 3D scanner, ideal for quality control, reverse engineering, jewelry, as well as medical/dental objects. Excels at capturing small objects with complex and intricate surfaces.
I worked in the domain of photogrammetry from aerial imagery and as far I can tell, the image quality is less important than the algorithm/program used for calculating the model. Maybe this helps your consideration.
