Traditional calibration methods of structured light measurement systems are expensive and difficult to operate. In this paper, an accurate, low-cost, and easy-to-operate calibration method is proposed, where each projector pixel is considered as a line-of-sight in space, and an off-the-shelf LCD monitor is used to display the calibration pattern. Experimental results verify the accuracy and validity of the proposed method. (C) 2016 Optical Society of America
