| 摘 要： | 从单线阵推扫式传感器的成像机理出发，利用6个卫星轨道开普勒参数和3个传感器姿态角建立了推扫式卫星遥感影像坐标与其地面点在地心坐标系下的坐标关系式，即构像方程。按照所建立的构像方程，对某地区一景SPOT-5影像进行对地目标定位，获得了实地上83．392m的平面精度；利用单个地面控制点对卫星轨道开普勒参数和传感器姿态实施调整后，目标定位精度提高到14．217m。试验证实，所建立的构像方程是正确的,在卫星遥感对地目标定位中有较好的应用前景。

| Abstract: | Sensor models are of particular importance to stereo measurements and image rectification. There have been so many researches on satellite camera models. In general, sensor models for satellite imagery can be categorized into two groups: physical and mathematical models. In this paper, according to the physical imaging process, we developed the geometric collinearity equation of pushbroom sensor with the Kepler parameters of the satellite orbit and the attitudes of sensor. By testing the sensor models on a SPOT-5 imagery, the accuracy of object location is 83.392 m. Then the authors adjust the Kepler parameters and attitudes by using one single GCP, the planimetric precision reaches 14.217m on the ground. Thus, the validity of the geometric model has been verified. |
