摘　　要：传感器成像几何模型是摄影测量数据处理的关键问题。本文分析了CE-1立体相机成像几何原理、阐述了立体相机内定向以及根据探月卫星辅助数据计算外定向参数的原理和方法;提出一种快速反投影变换算法,建立了CE-1立体相机成像几何模型。通过对CE-1三线阵影像、激光高度计数据的配准实验,验证了本文的有效性。本文立体相机成像几何模型将用于探月数据后续摄影测量几何处理。Sensor imaging geometric model is the key to the data processing in photogrametry. The CE-1 stereo camera imaging geometric principle was analyzed in this paper. An approach was proposed which CE-1 Laser footprints was reversely projected to CE-1 image using their exterior orientation parameters obtained from satellite orbit and attitude data about time. It was showed that the CE-1 Three- Line-Array CCD image and laser altimeter data of the geometry registration experiments verified the effectiveness of this geometric model. The established stereo camera imaging geometric model could be used in lunar exploration data for subsequent CE-1 image geometry processing.
