Abstract

Abstract: Due to the limitations of objective factors such as object occlusion and aerial photography blind area in the data acquisition process of traditional tilt photography, which cause problems such as 3D model distortion, holes, texture rasping, etc., the method of laser point cloud and tilt photography multi-source data fusion is selected for fine modeling of ancient buildings, which can improve the visual effect and accuracy of 3D models and expand the application field of achievements. In this paper, taking the historical block of guangfu ancient city as an example, through the fusion of multi-source data such as tilt photography, airborne LiDAR, ground hand-held radar and UAV re-shooting, the 3D real scene fine modeling is carried out, and good experimental results are obtained.

Key words: oblique photography, multi-source data fusion, 3D modeling
