无地面控制点条件下, 卫星摄影测量研究与工程实践是世界各国在该领域中所面临的研究难点之一。本文介绍了在无地面控制条件下光学卫星摄影测量的研究发展和工程实践历程, 并对中国“天绘一号”卫星获取的影像实测结果进行分析, 结果表明, 中国在无地面控制条件下的卫星摄影测量研究与工程实践已居于国际领先地位。

The study on the satellite photogrammetry and engineering practice without ground control points are the diffi culties to all researchers in this fi eld. This paper introduces domestic and international research activity in optics satellite photogrammetry without ground control points, and analyzes the images from Mapping Satellite-1. The result shows that China plays an international leading role in the study on satellite photogrammetry and engineering practice without ground control points.
