基于实景三维的城市空间综合治理平台建设

Construction of urban space comprehensive management platform based on real 3D

文章通过搭建统一的基于实景三维城市空间治理平台,采用“GIS引擎+虚幻引擎”双引擎架构解决GIS数据管理分析能力不足的问题,同时增强了精细场景的表现力;采用LOD多层级三维模型加载方法,减少渲染循环中需要处理的实体数据量,实现三维模型加载效率的提升;通过动态视频流技术加载倾斜模型,充分确保地理信息数据安全。以番禺区建设项目为例,在城市综合整治、三维辅助审批和城市品质提升等方面得到有效应用,为城市空间综合治理建设提供借鉴意义。

By building a unified three-dimensional urban spatial governance platform based on real life,this paper adopts the dual-engine architecture of"GIS engine+illusion engine"to solve the problem of insufficient GIS data management and analysis ability,and at the same time,enhances the expressive force of fine scenes.LOD multi-level 3D model loading method is adopted to reduce the amount of entity data to be processed in rendering cycle and improve the loading efficiency of 3D model.The skew model is loaded by dynamic video stream technology to fully ensure the security of geographic information data.Taking Panyu District construction project,as an example,it has been effectively applied in urban comprehensive improvement,three-dimensional auxiliary examination and approval and urban quality improvement,which provides reference for urban space comprehensive management construction.
