| 摘 要： | 将数码相机应用于摄影测量有明显的优势,然而由于相片失真的因素,测量精度一直为业内人士所诟病.针对数码相机的测量精度问题,进行误差原因分析,研究镜头畸变误差和光线折射误差计算方法,并开展相应的误差试验.实验结果表明：在滤除镜头畸变误差和光线折射误差后,采用数码相机进行摄影测量相对误差小于1%,可以满足一般测量的精度要求.

| Abstract: | Digital camera is often used for photographic surveying,however,the accuracy has been criticized for a long time.The paper analyzed the reasons.Moreover,computing methods about camera lens distortion error and light refraction error are studied,and carried out experiments.The findings show that after filtering those two kinds of errors,the accuracy will be less than 1%,which meet the general need for the accuracy. |
