摘　　要：简述Harris角点检测算法的原理、算法的执行流程和黑白棋盘格亚像素坐标求取的基本方法。通过实验检测出了黑白棋盘格中的角点,得到了角点坐标,并运用二次曲面拟合法得到了角点的亚像素坐标。简要分析Harris角点检测算法中各参数对检测结果的影响,给出了参数设置的一些心得。实验结果可以用于摄像机的标定。The principle of Harris comer detection algorithm, the execution flow of the algorithm and the basic ways of getting the sub-pix- el coordinate in black white checkerboard are presented in brief in this paper. All the comers needed in black white checkerboard are detected and all the coordinates of corners are calculated through the experiments. Sub-pixel coordinates of corners are calculated with quadric surface fitting. A brief analysis of the influence of the parameters in Harris corner detection algorithm to the test results is given in the paper. Some ad- vices of parameters setting in the algorithm are given as well. The result of experiment can be used in camera calibration.
