Abstract

Abstract: In the acquisition of 3D real scene data of buildings, ground 3D laser scanning and UAV tilt measurement are frequently used technical means. The data types obtained by the two means are different, and the display effect and accuracy of space are also different, especially in obtaining the top and near ground data of buildings. This paper studies the processing of the top data of buildings and the near ground 3D laser scanning data are processed, and the point cloud and model data are transformed and matched. The methods of field survey and internal processing are introduced by data acquisition of a ancient gate, and the fusion accuracy is analyzed and discussed.

Key words: 3D laser scanning, point cloud, UAV, tilt photogrammetry
