摘要
简述了摄像机标定的原理,介绍了Harris算子和Forstner算子的基本原理。针对摄像机标定模板的角点检测问题,提出了一种简便而精确的角点提取算法。该算法结合两种算子的优点,明显提高了角点坐标提取的精度,并且通过实验验证了该算法的有效性和准确性。
It briefly presents the calibration principles of a camera. Aiming at the comer detection probtem ot camera calibration template, it describes a simple and accurate comer extraction algorithm, proposes the basic principles of the Harris operator and Forstner operator, and further improves the two algorithms by combining their advantages. The experiment shows that the algorithm obviously improves the accuracy of comer extrac- tion algorithm.
