Automated Generation Control Points for Geometric Rectification of Workpiece Image

大型工件视觉图像畸变校正控制点的自动生成是提高畸变校正准确率的有效手段。文章应用图像分析处理和模式识别方法,提出一种畸变控制点自动生成算法。该算法从网格模板图像中自动提取网格交叉点,按照行列对交叉点进行编号,实现图像畸变校正。实验证明,该算法计算速度快、提取准确,校正精度高,能够提高工件的定位精度。

Automated generation of control points is useful to enhance geometric rectification＇s veracity.In this paper an automated recognition and computation algorithm are proposed for control points,which can automatically recognize intersections of image and number these intersections in sequence.Experimental result shows that the method is simple,exact and valid for improving the workpiece positioning accuracy.
