A Study on 3D Modeling of Building Based upon Photogrammetry

摘要

This article has analyzed three-dimensional city building modeling demand based on photogrammetry and the photogrammetric method in the building's three-dimensional reconstruction and the three-dimensional urban building data updating aspect superiority. It has also discussed three-dimensional urban building modeling method, the workflow and the technology based on the photogrammetry, and finally achieved high accuracy in three-dimensional reconstruction of both wide range city buildings and a single complex building.
