基于多源数据融合的三维实景重建及研究

Research and Reconstruction of 3D Real Scene Based on Multi-source Data Fusion

随着“数字地球”“实景三维中国”“智慧城市”建设的发展,无人机航摄技术、贴近摄影测量技术、LiDAR技术、倾斜摄影技术、SLAM等被越来越多地用于构建实景三维,但单一技术在三维重建上都存在局限性,尤其在建筑物精细建模方面,如纹理贴图遮挡、模型精度低等。本文以三维建模项目为基础,探讨多源数据融合的关键技术,并提出基于多源数据融合的三维重建技术方案。

With the introduction of“Digital Earth”,“Real 3D China”and“Smart City”,UAV aerial photography technology,closein photogrammetry technology,LiDAR technology,oblique photography technology,SLAM and so on have been more and more used in the construction of 3D real scene,but the single technology has limitations in 3D reconstruction,especially in the fine modeling of buildings,such as texture mapping occlusion and low model accuracy.Based on the 3D modeling project,this paper discusses the key technologies of multi-source data fusion,and proposes a 3D reconstruction technology scheme based on multi-source data fusion.
