3D reconstruction of specular objects with occlusion: A shape-from-scattering approach

Abstract

In this paper, we propose a method to measure specular objects regardless occlusion. The main contribution of this paper is that we have shown that the scattering of incident and specular reflection enable us to measure occluded surfaces. We locate objects in a tank filled with participating media, irradiate a laser beam to the objects, and observe the scattering of incident light and specular reflection. Occluded reflecting points of the laser are estimated from the peak pixel; scattering light that has local maximum intensity. Experimental results with a metallic specular plate demonstrate that our method can estimate the 3D position of occluded reflecting point.
