基于高精度Mesh的院落自动截图方法
An automatic screenshot method of courtyards based on high-precision Mesh
摘要
Abstract
Courtyard photos are an important component of digital building archives and play a key role in identifying and managing housing safety risks.Existing methods,primarily on-site photography and manual screenshots,generally suffer from large work-loads,low efficiency,unclear images,and inconsistent formats.Based on practical experience,this study proposed an automatic courtyard screenshot method based on high-precision mesh and integrated it into a two-dimensional(2D)and three-dimensional(3D)unified system.The method was applied in the refined management and governance of key areas in the urban-rural interface of Fangshan District,Beijing,to produce a"one image,one record"dataset for courtyard houses.The results show that the method generates comprehensive,clear,and accurate courtyard images,which improves work efficiency and provides important data support for achieving digital,intelligent,and refined management of houses.关键词
