摘要
该文概述了利用PixelGrid软件集群系统,基于已有的地理信息对基础测绘更新项目中使用的卫星影像快速纠正,并用与已有DOM的套合差和外业点对纠正成果进行精度检测,最终获取了满足精度要求的正射影像底图。
In this paper, the application of Pixel Grid software cluster system to the rapid correction of satellite images used in the Basic Mapping and Renewal Project based on existing geographical information is summarized, and the accuracy of the results is measured by using the interface and outfield points of the existing DOM.Finally, a positive projective image bottom map is obtained which meets the requirements of accuracy.
