摘要
Systems and methods are disclosed for determining three dimensional (3D) shape by capturing with a camera a plurality of images of an object in differential motion; derive a general relation that relates spatial and temporal image derivatives to BRDF derivatives; exploiting rank deficiency to eliminate BRDF terms and recover depth or normal for directional lighting; and using depth-normal-BRDF relation to recover depth or normal for unknown arbitrary lightings.
