An Improved Camera Calibration Method

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 method 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.
