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 geometry is the key issue in photogrammetry data processing. This paper analyzes the imaging principle of the CE-1 stereo camera, expounds the principle and method of the directional orientation of the stereo camera and the calculation of the outer orientation parameter based on the lunar satellite auxiliary data, and proposes a fast back projection transformation algorithm and the CE-1 stereo camera Imaging geometric model. The effectiveness of this paper is validated by the registration experiment of CE-1 three-line array and laser altimeter data. In this paper, three-dimensional camera imaging geometric model will be used for lunar data follow-up photogrammetry geometric processing.
