Abstract
Range-images of the Time-of-Flight (TOF) camera are affected by errors owing to the scattered light inside the camera body (flare light) and by the indirect (diffuse) light. The 3D images are distorted because the errors of the range-image depend on the surfaces’ reflectivity. The presented algorithm, based on a modified TOF camera, computes a correction vector that corresponds to the average effect of the diffuse and flare light. The enhanced range-image is obtained by subtracting this vector from the recorded vector image. In this manner, the range-image distortions in the dark regions are reduced.
