实景三维在城市国土空间监测中的应用
Application of real-world three-dimensional model in urban land and space monitoring
摘要
Abstract
This paper focused on the real-world three-dimensional(3D)model and urban land and space monitoring work in Baiyin District,Baiyin City,Gansu Province.It elaborated on the concept of real-world 3D model and its role in urban land and space monitoring.The study employed unmanned aerial vehicle(UAV)oblique photography technology to create city-level real-world 3D models and used Beijing-3 stereoscopic satellite imagery to generate terrain-level real-world 3D models.Based on the fused global real-world 3D model,urban land and space monitoring tasks were conducted,including the collec-tion of water networks,road networks,detailed space use,as well as the collection of building floor contours,heights,num-ber of floors,and other attribute information within urban areas.The results show that real-world 3D technology has broad applications in urban land and space monitoring and can provide essential data support for land space planning,implementa-tion,and urban assessments in natural resource management.关键词
