摘　　要：以提高相机标定效率和自动化程度为目的,提出一种相机自动标定方法.传统相机标定需要手工标识,工作量大、效率低.使用自制标定模板,应用特征点检测技术代替手工标记,实现自动检测标记点并自动排序,标定精度和原算法基本一致,而且可靠性好,实用性较强,简化了标定过程.An automatic camera calibration method based on conventional camera calibration is proposed. The camera calibration method is studied in order to improve the efficiency and automation grade of camera calibration. The conventional camera calibration needs marking the marker point by handwork with a high workload, low efficiency and unwarranted precision. The new meth- od uses home-made calibration template and detects marker point automatically instead of handwork, which can detect and sort the feature points automatically. Experiments demonstrate that this new method has the same calibration precision as original one, but has steady reliability, strong practicability, and predigests the camera calibration course.
