Automatic location checking of digital camera control point

In order to simplify the tedious work of controlling the manual measurement control point in the field camera, and to improve the accuracy of the camera calibration, this paper proposes a method: To obtain the initial parameters of the camera inspection by the uniform measurement of the image square coordinates of a small number of control points, it is possible to use the dynamic template matching to realize the high precision automatic locating and checking of The experimental results show that the accuracy of this method is similar to that of the manual measurement and inspection.
