摘　　要：针对LMCCD相机摄影特点，在三线阵EFP光束法平差理论的基础上，分析了LMCCD影像光束法平差理论的关键技术点，并利用模拟数据和天绘一号卫星影像进行试验验证。试验结果表明，LMCCD影像EFP光束法平差，实现了平差中三角锁之间的固定联接，解决了航线模型的变形，能有效提高卫星影像无地面控制点条件下的定位精度。According to the photography characteristics of the LMCCD camera, the key technical points for the bundle ad- justment method of LMCCD image is analyzed based on the EFP bundle adjustment of the three- line array, and the test is con- ducted using simulation data and TH - 1 satellite image. The result of the experiment shows that the EFP bundle adjustment of LMCCD image can implement the adjustment of the fixed connection in the triangulation chain, solve the deformation problem of the route model, and effectively improve positioning accuracy of satellite image without ground control points.
