Active triangulation methods assume that points in a scene are only illuminated by the sources of light. However, this assumption is valid only when the light is reflected at one time from a single convex surface. Actual objects often include concave surfaces where points reflect light between themselves. In the presence of these inter-reflections, active triangulation methods produce erroneous estimates of shape. In this paper, an approach is proposed to recover the shape of a specular object in the presence of inter-reflection, with prior knowledge on the shape information of specular object or not. Both simulation and experiment results proved that the proposed approach was effective.
