Shape from active shadow motion

摘要: We propose an active vision technique for recovering object shape and absolute position information. The algorithm relies on the controlled motion of a point light source reasonable assumptions general objects. sequence shadow images created by illuminant is used to produce surface In this approach not at infinity rays are parallel. For case objects with `sharp' edges, our requires only solving linear system equations. provide sensitivity analysis as basis robust estimation depth values. Simulations experiments performed demonstrate efficacy algorithm.
