METHOD, APPARATUS AND SYSTEM FOR DETERMINING NORMAL AND REFLECTANCE PARAMETERS USING SEQUENTIAL ILLUMINATION

摘要

A method, apparatus and system for the determination of normal and reflectance parameters using sequential illumination and recorded depth information include illuminating a scene using a light source such that every other frame of the scene recorded by a camera is illuminated by the multiplexed light source. Depth data of the scene is recorded concurrent with the recording of the scene by the camera. A light source contribution image for the scene is determined using a difference between recorded images containing the light source illumination and recorded images not containing the multiplexed light source illumination. Finally, the normal and reflectance parameters are determined using the recorded depth information and the light source contribution image.
