摘要：
This article, in view of the non-metric digital camera characteristic, analyses the error sources. Then this paper has founded the mathematical model of the camera calibration. puts forward the adoption of the multi-images iteration method to calculate the coefficients of the DLT and distortion parameters in groups by three-dimensional ground control points, and it also performs the comparative experiments with commercial software "Australias" and "V-STARS". The precision of camera calibration are confirmed by the experiments of resection and forward intersection, and the satisfactory effect is obtained.
