| 摘 要： | 数码相机的检验是近景摄影测量中经常碰到的问题。最常用的主要还是基于共线方程的后方交会法。但由于普通数码相机存在较大的镜头畸变，内方位元素也未知，所以仅用单片进行后方交会求取有关参数时，法方程可能会出现病态现象，从而影响最后的检验结果。文中对此现象进行了讨论，并给出了一些实用的解决方法。

| Abstract: | Digital camera calibration is one of the main problems in close-range photogrammetry.The main method is resection based on collinearity equation.However, due to obvious lens distortion of ordinary digital camera, and inner orientation parameters are unknown, when we solve parameters by resection with single image, the normal equation may be sick, so as to affect the final results.This paper discussed this phenomenon and gives some practical solutions. |
