摘　　要：在CCD相机应用于城市规划、古建保护等领域中,为保证量测结果的精度,需要通过相机校正确定畸变差、内方位元素等参数。本文利用移动控制架提供的多层面、立体控制点,通过单片后方交会方法进行相机检校。结果表明,基于移动控制架的相机校正方法是可行的,结果精度良好。In recent years, close range photogrammetry was applied into the fields of city planning and ancient buildings protecting. The calibration of CCD camera was important to get an ideal result. In the paper, the focus items to be calibrated were interior elements and optical distortion. To keep the accuracy of the calibration result, the paper put forward calibration method based on an active control frame. 93 control points were established in the active control frame. The objects together with the control frame were taken in the same photos. Based on spatial resection method, the calibration of CCD camera could be finished. The results of calibration from different photos showed that it was a feasible method for provi- ding high accuracy to satisfy certain requirements.
