The automatic accurate target scoring system based on computer vision needs to correct the image of the target the combination of Hough transform and geometric correction. This article describes a geometric correction algorithm. Based on this, the Hough transform is used to detect the line. The control points which are used for the image correction are getting from the point of intersection of the straight line. The algorithm can carry out the image correction effectively and provide a great help for the post processing. Experimental results show that the algorithm is feasible and effective.
