The principle of structured light 3 - D vision is introduced, and using projective and perspective transformations, the mathematical model of grid structured light based 3 - D vision inspection is established in homogeneous coordinate system in this paper. Based on the image feature analysis of grid structured light, a calibration method of grid structured light based 3 - D vision inspection is proposed, and experimental results are also presented. This method is easy, efficient and fast to carry out. It simplifies the calibration process while guaranteeing its accuracy.
