摘　　要：由于旋翼无人机航摄技术反应快速、成本低、工作量小、成图快、机动性强[1]等特点,近年来在大比例尺地形图测绘中得到了广泛的应用,随着该项技术在软硬件方面的不断完善,其在大比例尺地形图成图精度方面也有了很大的提高,可以满足1∶2 000地形图的成图要求。结合以Ecan-Umap无人机单兵智能化航测系统完成的咸阳市泾阳县祁家坡矿区测量项目,介绍四旋翼无人机在大比例尺地形图测绘的内外业全过程,包括控制测量、航空摄影、像控点布设及测量、影像畸变差纠正、空三加密、DOM/DEM制作、DLG生成等[2],最终经过对检查点的精度评定及误差分析,进一步验证四旋翼航摄无人机在小区域大比例尺地形图测绘应用方面的可行性。As the airphoto technology of rotary-wing drone features rapid response speed,low cost and work load,quick mapping produc-tion and strong motivated performance, it is widely applied in topo-mapping with large scale. With increasing improvement of the technol-ogy in hardware and software, its performance is improved in term of the large-scale topo-mapping precision and can satisfy requirement of 1 颐 2 000 topo-mapping. With description of Ecan-Umap drone independently fulfilling the aerial survey of Qijiabo mining area, Jingy- ang County, the whole process of the quadcopter drone in the large-scale topo-mapping is introduced including control surveying, airpho-to, distribution and surveying of image control points, correction of image distortion difference, aerial triangulation encrypt, DOM/DEM making, DLG production, etc. Finally, feasibility of application of the quadcopter airphoto drone in large-scale topo-mapping for a small region is further proved by precision assessment and error analysis of the inspected points.
