ABSTRACT

In recent years, computer vision has been widely studied and applied. Camera calibration is the first step in image processing and an indispensable step to obtain three-dimensional information from two-dimensional images. The quality of the calibration results directly determines the quality of the image and the system accuracy of computer vision. Therefore, the study of camera calibration methods has important theoretical significance and practical application value. Aiming at the problems of camera calibration, and combined with the research results in recent years, several common problems and improvements of camera calibration are summarized and compared, and their advantages and disadvantages are briefly analyzed here in this paper.
