Abstract
Aiming at the corner detection for calibration board of chessboard pattern in the camera, a kind of cor-ner detection algorithm has been put forward based on the image pixel distribution. Firstly, the even zone points are removed by estimating the number of similar points around the pixel point 8 . Then the upper matrix of diago-nal is extracted according to the feature of height symmetry in chessboard pattern image to determine whether the central point is the corner candidate. At the end, through the calculation of the selected corner candidates getting the coordinate in average and the final angle point is obtained. The experimental result shows that the method can solve the testing problem of the chessboard angle points in a better way.关键词
