摘要
GPS辅助航测技术的推广应用,降低了传统像片控制测量的作业成本,优化了传统空三加密工序的技术流程,从而有效缩短了航测法成图周期。本文以永城市1∶1 000地形图测绘生产为例,介绍了应用GPS辅助空三数据生产的作业流程、生产过程出现的有关问题,并对几种不同的布点方案应用GPS辅助光束法区域网平差的成果进行精度统计和分析。
The popularization and application of the GPS assisted Photogrammetry reduced the cost of the traditional photograph control survey,optimized the technical flow of the traditional spatial triangulation encryption,thus effectively reduced the Photogrammetry-based map production cycle.In this paper,by taking the Yongcheng city 1∶1 000 topographic mapping production as an example,we introduce the workflow of GPS assisted spatial triangulation encryption and the related issues during map production process,meanwhile,we also statistic and analyze the block-net adjustment results from several different layout scheme solutions of control point by using GPS assisted flux of light method.
