摘　　要：受现今轨道和姿态测量以及姿态控制精度的限制,与传统三线阵立体测绘相比,采用线面阵CCD阵列(LMCCD)测绘体制可提高全球无地面控制点立体测绘精度。详细介绍了LMCCD立体测绘体制下的传感器配置、时间延迟积分(TDI)工作方式及狭小空间线路板连接和LMCCD同步控制方法。经测试该相机能有效削减测轨、测姿误差,满足无地面控制点1:50 000比例尺地图应用要求,性能还可进一步改进提高。Traditional three line array stereoscopic mapping is constrainted by orbit determination precision, attitude determination and control precision. Compared with it, the line-matrix CCD array （LMCCD） camera structure can improve the global stereo mapping precision without ground control points （GCPs）. The related subject in detail, which included sensor configuration of stereo mapping of LMCCD, TDI working mode, PCB connecting method in narrow space, time scale generation and LMCCD synchronous control was described. The tests indicate that the LMCCD mapping camera can effectively reduced orbit and attitude measurement error. It meets the requirements of 1：50 000 scale maps without GCPs, and the performance can be improved in future application.
