摘　　要：随着无人机产业的飞速发展,无人机航测作为一种新型地形图生产方式已然成为一种不可替代趋势。文中基于飞马D200无人机航测系统,在以实际矿山生态恢复治理航测地形图生产的背景下,利用ArcGIS、CASS相结合和EPS三维测图系统两种成图方法进行应用比较研究。结果表明:两种方法都可以满足小区域大比例尺航测地形图的生产要求,但前者生产成本低,使用效率高,易普及,后者精度更佳,便于数据库生产和后期数据维护。With the rapid development of UAV industry,UAV aerial survey as a new type of topographic map production had become an irreplaceable trend.Based on the application of FEIMA D200 UAV,in this paper,two mapping methods of the combination of ArcGIS,CASS and EPS 3D mapping system were used to compare the application.Results showed that the two methods could meet the production requirements of large scale aerial mapping in the small area,but the former was the advantages of low production cost,high efficiency and easy to popularize,and the latter had the better accuracy,which was convenient for database production and later data maintenance.
