本文对高分辨率遥感卫星传感器严格成像模型进行了深入研究。分析了星载线阵CCD传感器严格成像模型的一般建立方法与过程,针对SPOT 5 HRS/HRG、ALOS PRISM、资源三号TLC等典型的高分辨率遥感卫星传感器特点,分别给出了3种改化的严格成像模型;设计了基于光束法区域网平差的模型验证方法。利用登封遥感实验场区域的3种卫星影像及相关辅助数据,对严格成像模型的正确性进行了验证。结果表明3种改化模型可有效实现卫星影像的平差定位。

We present an in-depth study on the rigorous imaging model of high-resolution remote sensing satellites. After a brief analysis of the generally established method and process of developing the rigorous imaging model of a spaceborne linear array CCD sensor, three improved rigorous imaging models are proposed for the SPOT 5 HRS/HRG, ALOS PRISM, ZY-3 TLC, and other typical high-resolution remote sensing satellite sensors. We also propose the design of a model validation method based on the bundle block adjustment. The correctness of the rigorous imaging improvement models is verified using three types of satellite images and ancillary data over the Dengfeng remote sensing test field. Experimental results confirm that the three improvement imaging models are correct and applicable for effectively realizing geopositioning and block adjustment of the satellite images.
