| 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. |
