    Camera calibration is the most basic part of the vision system. It uses the camera imaging principle to solve the internal and external parameters of the camera model, so as to better realize the application of the vision system in practice. Based on the analysis of the characteristics of camera calibration and the development of camera calibration at home and abroad, the calibration objects are divided into three-dimensional calibration method, two-dimensional calibration method, one-dimensional calibration method and zero-dimensional self-calibration method. This paper introduces firstly the origin and development of each camera calibration method, then analyzes the basic principle of each camera calibration method in detail, and summarizes the advantages and disadvantages of each calibration method. The development trend of calibration technology is predicted. In the case of complex scene and large amount of computation, the main research contents should be high precision, high efficiency and high robustness, so as to further expand the scope of application and enhance the practicability. At the same time, the cost of camera calibration should also be taken into account, to find a more suitable calibration method.
