摘要
卫星摄影测量是一种高效的地理空间信息数据获取手段,在全球的基础测绘中发挥着重要作用。本文回顾了笔者亲历的我国卫星摄影测量发展的两个阶段,重点对线阵推扫影像进行空中三角测量平差的理论进行了介绍,并以天绘一号工程实践为依据,表明了我国自主的理论创新,线阵立体影像单航线平差无控定位精度也能够达到框幅相机静态摄影影像理论水平。
Satellite photogrammetry is a new means of obtaining geospatial information data,and it plays an important role in the global basic surveying and mapping.In this paper,the author reviewed the two stages of the development of satellite photogrammetry from personal experience in our country.Then,the theory of aerial triangulation adjustment for linear array push-broom image is mainly introduced.Finally,based on the engineering practice of TH-1 satellite,it is shown that through our independent theoretical innovation,the high location accuracy without ground control points(GCPs)can be achieved using single strip linear array stereo images,which can also reach the theoretical level of frame camera images.
