文章首先简要叙述了基于＂资源三号＂（ZY-3）卫星三线阵TLC影像的严格几何成像模型,然后建立了针对外方位角元素的系统误差补偿模型与相机视向量几何检校模型。经地面系统检校后,采用地面高精度控制点数据对非同时相影像进行试验,并对影像平面精度进行分析评价。结果显示ZY-3三线阵TLC影像无控制点状态下外部定位精度优于6像元,内部几何变形优于1.5像元。

The paper mainly researches and analyses the geometric quality of three-line array CCD（TLC） imagery of ZY-3 satellite, and introduces the processing flow of geometric positioning relative to ground of three- line array CCD imagery. After a brief description of the strict geometric imaging model of three-line array CCD imagery of ZY-3 satellite, the paper establishes the error compensation model according to the exterior orientation angle elements and the geometric calibration of camera orthogonal. After the system calibration on the ground, by using different times imagery and high precise ground control points,a test is conducted,and the plane precision of the imagery is analysed and evaluated. The results show that without Ground Control Points,the external positioning accuracy of three-line array CCD imagery of ZY-3 satellite is better than 6 pixel, and the internal geometric deformation less than 1.5 pixel.
