摘要
分析了刀具柱面Data Matrix(DM)码几何畸变的原理与过程,利用透视投影的方法建立了柱面DM码的几何畸变模型并对其进行仿真.结果表明,该模型较好地模拟了DM码在刀具柱面的几何畸变状况.通过仿真分析,获得了在一定曲率柱面上标刻DM码的合适尺寸以及采集过程中相机的合适几何参数.
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.
