摘要
本文以2018年甘肃省基础测绘临夏测区为例,尝试以天狼星无人机航测系统生产的高分辨率DSM、DOM为基础,进行大比例尺地形图测绘。经过航摄飞行、数据处理,生产获得DSM、DOM成果数据,然后通过大量外业检查点对其进行检核、统计和分析。结果表明:该系统生产的DSM、DOM成果精度在地貌相对简单的区域满足规范要求,而在地貌环境相对复杂的区域精度不能满足规范要求。
Taking Linxia surveying area of basic surveying and mapping in Gansu Province in 2018 as an example,this article attempted to produce large-scale DLG based on high resolution DSM and DOM by SIRIUS Pro aerial survey system.After aerial photography and data processing,DSM and DOM results data were obtained,Then it was checked,counted and analyzed through a large number of field checkpoints.The result indicated that:the accuracy of DSM and DOM results produced by this system could requirements of the specifications in areas with relatively simple landforms.However,the accuracy in regional relatively complex geomorphological environment could not meet the requirements.
