摘要：Camera calibration is a main feature in photogrammetric 3-D object restitution. Calibration parameters such as principal distance, principal point and lens distortion are usually determined by a self-calibrating approach, i.e. they are calculated simultaneously with the object reconstruction by a bundle adjustment based on the collinearity equations and additional correction functions. The adjustment results in the unknown parameters of the interior and exterior orientation and the 3-D object coordinates. The quality of the result depends on several influences, mainly on the image configuration. If the network geometry is not adequate to self- calibration, a priori knowledge about the camera parameters is required, e.g., obtained by testfield calibration. Besides, it can be of interest to transfer the interior orientation parameters determined by a self-calibrating bundle adjustment to another object reconstruction software. This paper reports on the investigation of several bundle programs used to camera calibration. The calibration models are described and the results of self-calibration are discussed
