Abstract

Abstract: Aiming at the problem of real 3D modeling of towering ancient pagodas, a unmanned aerial vehicle (UAV) three-phase loop shooting video homogeneous frame modeling method is proposed. A small multi-rotor drone equipped with a single-lens camera is selected, and three phases of high, medium and low are arranged to capture video around the towering ancient pagoda and perform even frame processing. The Chengtian temple pagoda in Xingqing district, Yinchuan city, Ningxia, is selected as the test object for example modeling and compared with the widely used UAV photo-photographic oblique photography modeling method in 3 aspects: modeling efficiency, modeling air-three quality and overall model quality. The results show that the modeling effect of the method is better than the three-dimensional modeling effect of UAV oblique photography. On the basis of optimizing the acquisition process and simplifying the equipment conditions, the integrity of the model is guaranteed, and the modeling efficiency and modeling quality are improved.

Key words: towering ancient pagodas, UAV, three-phase loop shooting, video homogeneous frame, 3D modeling
