| Abstract: | The theory and process of geometrical distortion of Data Matrix (DM) code on tool cylinder were analysed. And the distortion modeling and simulation of DM code image were induced based on the perspective projection. The result shows that the model can better simulate the distortion of DM code on the tool cylinder. Through simulation analysis, appropriate size of DM code marked on certain curvature tool cylinder and appropriate geometric parameters of camera in acquisition process were obtained. |
