In order to improve the calibration accuracy and efficiency of the camera, a camera calibration method based on single two-dimensional image is proposed in this paper. Method of least squares is used to calculate the mathematical model between the world coordinate system and the computer image coordinate system, so that the problem that the Internal and external camera parameters and difficult to calculate directly and that the calculation accuracy is not high can be solved effectively. Calibration accuracy and reliability are guaranteed and also the calibration efficiency is improved in this method. Under normal circumstances, when there are three-dimensional world coordinates and its computer image coordinates of six known points in the space, then camera calibration can be realized. The calibration accuracy can be further improved if the number of space known point is increased. A large number of calibration image data is tested to improve that this calibration method has high accuracy and small amount of calculation, and improves the reliability and accuracy of the camera calibration. This method has theoretical significance and practical value.
