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 aerospace three-line array stereo mapping camera is composed of three linear cameras with independent lenses. The three linear cameras maintain a certain positional relationship which is the characteristic of the large aerospace three-line array stereo mapping camera. The influence of angular displacement and line displacement on the height measurement accuracy and plane measurement accuracy of large aerospace three-line array stereo camera was analyzed. The sensitive factors in the design and manufacture of large aerospace three-line array stereo camera were obtained. In order to ensure the space flight three- Realization of the accuracy of the camera mapping, design and manufacture to reduce the difficulty and cost indicate the direction of efforts.
