摘要
针对资源三号影像无地面控制的对地目标定位研究的不足,该文从资源三号成像传感器的成像机理出发,通过对焦平面坐标系内CCD探元系统误差的分析,提出一种基于CCD探元系统误差补偿的资源三号影像对地目标定位方法。试验结果表明,在无需对资源三号成像传感器进行在轨几何定标的情况下,该方法可以有效消除定位结果中的系统误差,提高资源三号影像无地面控制对地目标定位精度。
Aiming at the insufficiency of studying the object positioning without ground control for ZY- 3 images, the paper analyzed the systematic errors of CCD detectors in a focal plane coordinate system according to the imaging mechanism of ZY-3 satellite sensors, and proposed an object positioning method for ZY-3 images based on the compensation for the systematic errors of CCD detectors. Experimental results showed that the systematic errors of object positioning could be effectively eliminated under the circum- stances that there is no geometric calibration of ZY-3 satellite sensors, which improved the object positio- ning accuracy without ground control points for ZY-3 images.
