Abstract
En 中文
Interreflections introduced by points in a scene are not only illuminated by the light source used but also by other points in the scene. Interreflections cause inaccuracy and the failure of 3D recovery and optical measurements. In this research, a novel method for separating interreflections through parallel single-pixel imaging (PSI) is proposed, which can decompose interreflections into 1st bounce light, 2nd bounce light, and a higher order light component. PSI is used in obtaining the light transport coefficients of each camera pixel, and light transport coefficients are used in decomposing the intensity distribution of a projector and the component of interreflections. Results show that the proposed method can separate the interreflections of a real static scene in a concave surface.
