CE‐1三线阵立体相机和激光高度计主要用于获取月球形貌信息。CE‐1沿轨运动过程中，可同时获取高分辨率的三线阵扫描影像和高精度的激光测高数据。在分析立体影像与激光高度计数据不一致性的基础上，为提高定位精度，将激光测距数据引入三线阵立体影像光束法平差处理。本文提出一种改进的外定向参数模型，采用3阶Lagrange多项式模型（LPM）建立外定向线元素内插模型，采用四元数球面线性内插建立外定向角元素模型，并根据改进模型建立激光高度计数据与影像数据的联合平差数学模型。试验表明，本文立体相机和激光高度计数据联合平差模型是有效的。

CE‐1 carries two types of mapping equipments:CE‐1 Lunar laser altimeter and three‐line‐array stereo camera .Laser altimeter collects accurate laser altimetry data over the Lunar surface ,while stereo camera acquires high resolution three‐line‐array CCD images .By means of an inconsistency analysis of stereo image and laser altimeter data ,the CE‐1 Laser altimeter ranges are expected to be incorporated into the bundle adjustment as measurements to improve accuracy of CE‐1 image photogrammetric reduction .An improved exterior orientation model is proposed in which exterior orientation line element interpol ation model is established with the 3 order Lagrange polynomi al and the attitude interpol ation model is established using spherical linear interpolation of quaternion .Secondly , a bundle combined adjustment of CE‐1 stereo camera image and laser altimeter data is developed and implemented in this paper .experiment results show that the bundle combined adjustment model is effective .
