| Abstract: | 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. |
| Keywords: | workpiece image distortion generation rectification control points pattern match |
