| 摘 要： | 在摄像机自标定过程中，可根据Harris的检测算法提取对角点。该算法简单有效，非常稳定。在图像旋转、灰度、噪声影响和视点变换的条件下，与其他算子相比，是最稳定的一种点特征提取算子。为了获得亚像素级的角点坐标．需要引入迭代算法进行优化。试验证明该方法可大幅度提高摄像机的标定精度。

| Abstract: | According to the Harris algorithm extract corners before proceed camera self-calibration.The algorithm is simple,effective,stable.It is a stablest extract algorithm of corners feature at conditions such as image rotating grey and noise influence and sight alternating,compared with other algorithm.Inorder to obtain the coordinates of the corners on a sub-pixel level,it needs to put an iterated method.It is tested that the accuracy of the camera calibration is enhanced largely. |
