摘　　要：在资源三号测绘卫星全色影像立体定位严格几何模型的基础上,提出运用罗德里格矩阵建立姿态角常差检校模型,根据少量地面控制点求出姿态角常差构成的矩阵后,使影像定位精度得到显著提高。同时与利用线性化的姿态角常差改正模型进行了比较,并总结了各自的优缺点。In this paper, Rodriguez Matrix is proposed to establish constant angular error calibration model on the basis of the rigorous geometric model of ZY-03 in stereo positioning by panchromatic images. Once the constant angular errors are eliminated by using a few GCPs, the positioning accuracy will be significantly improved. Meanwhile, the model with the use of linearization is compared, and their advantages and disadvantages are summarized respectively.
