Calibration method for structured light based panoramic sensor with planar mirror

摘要

System calibration is one of the most important steps during SL (structured light) measurement that largely affects measurement results. To a panoramic SL system, the existing calibration methods, mainly adapted from general SL system, may fail when the common FOV (field of view) of the projector and camera is narrow. A calibration method using a planar mirror for omnidirectional SL system is proposed in this paper. Experimental results validate the effectiveness of this method.
