摘要: 研发了一种适合于大范围1∶500的无人机测图方案,围绕平面和高程点位中误差在5 cm以内这一核心目标,从无人机的平台稳定性、空中精准定位飞控、空三与三维建模及模型与影像结合的多视角测图等方面进行了设计。在广州马沥村的应用表明,本文研究的无人机倾斜摄影方案可以满足1∶500高精度的三维测图,并具有较高的效率。

Abstract: This paper presents a plan for 1:500 large scale topographic mapping based on UAV. To control the root mean square error of the point in plane and elevation direction within 5 cm, several improvements have been made for UAVs, including platform stability, accurate positioning and control in flight, aerotriangulation and three-dimensional modeling, as well as image combined multi-view mapping. The application in Mali Village of Guangzhou indicates that, the UAV oblique photography plan shows great potential in the 1:500 three-dimensional mapping in terms of accuracy and efficiency.

Key words: unmanned aerial vehicle, oblique photography, large scale topographic mapping, real three-dimensional scenes, multi-view combined mapping
