| 摘 要： | 对相机标定中常用的两种亚像素角点定位算法进行了比较,并对测试图像进行了角点定位实验。对于在实验中发现的直线拟合法的失效情形,提出了利用空间矩进行亚像素边缘提取后再进行直线拟合的改进方法。经用张正友标定法进行模拟相机标定,证明改进后的直线拟合法可明显提高标定精度。

| Abstract: | The paper compares the universal methods for subpixel corner detection used in calibration process and do an experiment with some images to test these methods.To the fault case when using line fitting,the paper gives a method that locates the subpixel edge by space moment before uses line fitting.By experiment with the improved method and Zhang calibration method we can see the notable improvement of calibration precision. |
