摘　　要：大型航天三线阵立体测绘相机是由具有独立镜头的三个线阵相机组成的,三个线阵相机保持一定的位置关系是大型航天三线阵立体测绘相机的特点。分析了角位移和线位移对大型航天三线阵立体测绘相机的高程测量精度和平面测量精度的影响,获得了大型航天三线阵立体测绘相机设计制造中的敏感因素,为保证大型航天三线阵立体测绘相机测绘精度的实现,降低设计制造难度和成本指明了努力的方向。The large-scale space three-linear array stereo-mapping camera is consisted of three independent three-linear array cameras. The positional precision must be kept among the three independent three-linear array cameras. This is the characteristic of the large-scale space three-linear array stereo-mapping camera. That the angle displacement and the line displacement affect the photogrammetric elevation and plane precision was analyzed. The sensitive factors of the large-scale space three-linear array camera making were presented. The way of carrying out the large-so_ale space three-linear array stereo-mapping camera mapping precision and cutting down the making difficulty and cost are given.
