A simple method for 3D shape reconstruction

To infer 3D descriptors of the scene one can use image(s) captured from camera(s). With respect to the illumination of the scene there are passive and active approaches. The later ones are particularly suitable for objects with no texture. The paper represents 3D reconstruction system with commercially available pair of cameras and video projector, as source of active illumination.. Furthermore, algorithms involved are simple and easily implemented. Practical reconstruction results along with systems;strengths and weaknesses are presented as well.
