摘要: 由于传统倾斜摄影在数据采集过程中,存在物体遮挡、航摄盲区等客观因素限制,造成三维模型扭曲、空洞、纹理拉花等问题,选择采用激光点云与倾斜摄影多源数据相融合的方式进行古建筑物精细化建模,可改善三维模型的视觉效果与精度,扩展成果应用领域。本文以广府古城历史街区为例,通过对倾斜摄影、机载激光雷达、地面手持雷达及无人机补拍等多源数据进行融合,实现了三维实景精细化建模,获得较好的试验效果。

关键词: 倾斜摄影, 多源数据融合, 三维建模

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
