This paper surveys the developments of the last 10 years in the area of camera self-calibration. In order to solve this problem, researches have used the camera intrinsic constraints separately and in conjunction with the camera motion constraints or the scene constraints. Most of the self-calibration algorithms are concerned with unknown but constant intrinsic camera parameters. Recently, camera self-calibration in the case of varying intrinsic camera parameters was also studied. We present the basic theories behind the different self-calibration techniques and discuss the ideas behind most of the self-calibration algorithms.
