摘　　要：对数学形态学中腐蚀和膨胀原理进行研究,提出针对常用的对称十字二维平面标定板图像的特征点提取算法。结合改进的Tasi两步法,选取经典的带一阶径向畸变的小孔摄像机模型,对MV-1300UC数字CCD摄像机进行标定。实验结果表明,该方法能够达到较高标定精度,平均标定误差为0.025 3 mm,且计算效率高,易于实现。Based on the erosion and dilation operations of mathematical morphology, a feature extraction algorithm was proposed to calibrate a 2-D plane graph. The common symmetric cross calibration plate was employed. The classical pinhole camera model with one order radial distortion was selected and the improved Tasi two-stage method was used to calibrate the MV-1300UC digital CCD camera. The error analysis of the calibration results shows that the proposed algorithm can reach relatively higher extraction accuracy, the mean error is 0. 025 3 mm and the calculation efficiency is high, also it is easy to realize.
