【Abstract】 The principle of structured light 3 D vision is introduced in this paper. Based on projective and perspective transformations, the mathematical model of the structured light is established in a homogeneous coordinate system. Also a calibration method is proposed using nonlinear least square. Finally,the vision system is established, and the experimental result is given.更多还原
