| 摘 要： | 简要介绍高分辨率卫星遥感影像的严格几何处理模型,提出较为严密的影像姿态角系统误差检校模型。通过对SPOT-5、CBERS-02B两种卫星遥感影像的试验证实模型的正确性和方法的有效性。对影像姿态角系统误差进行补偿后,可明显提高卫星遥感影像对地目标定位的精度,且优于影像姿态角常差检校的效果,目标点平面定位精度达到了±(2～3)像素的水平。

| Abstract: | The object positioning accuracy from high resolution satellite imagery is strongly relevant to image attitude data accuracy,but the attitude data have generally systematic errors and the object location becomes unreliable.The angular systematic error calibration model is stricter than constant angular error calibration model,based on the rigorous geometric processing model of high resolution satellite remote sensing imagery.The calibration model was tested on SPOT-5 and CBERS-02B images and both have proved its correctness.After compensating the angular systematic errors of images,the direct georeferencing accuracy can reach ±(2～3) pixels,which is much better than results of constant angular calibration. |
