摘要
利用低空无人机摄影系统采集的影像数据制作数字线划图是目前编绘各种比例尺地形图的主要手段,由于生产技术和要求的不同,如何快速高效的制作符合精度要求的线划图是重中之重。据此,文章结合一个实际案例,分析了Sky Photo-Map3D在制作1∶1 000高精度数字线划图的主要过程及成果精度,为以后各领域线划图的快速制作提供参考。
Producing Digital Line Graphic（DLG）with the image data collected by low altitude UAV is now the main method for compiling various scale to pographic maps.Due to the difference in production technology and requirements,how to quickly and effectively produce DLG to meet the accuracy requirements has been a top priority.On the basis of actual cases,this article analyzes the main process and the accuracy of results of using SkyPhoto-Map3D to produce a 1∶ 1 000 high-precision DLG,aiming to provide a reference for the rapid production of DLG in various fields.
