污染场地修复状况航测监控与三维可视化展示技术研究——以合肥市某污染修复场地为例

A research on aerial survey monitoring of the remediation status of a contaminated site and its 3D visualization display——A case study of a contaminated site under remediation in Hefei City

污染场地修复状况监控是一项涉及人、机、物、环等的复杂系统工程。针对污染修复场地监控面广、点多的特点,本文以某修复地块为例,采用无人机航测技术周期性采集场地视频、照片,结合修复地块等数据,经一系列数据标准化处理后,分别建立实景三维模型和修复地块数据库;基于Cesium开源GIS技术,搭建三维可视化展示平台,集成、发布及展示各项修复成果,为场地动态监控和数据三维可视化提供解决方案。

Monitoring the remediation status of a contaminated site is a complex system engineering involving the human,machine,material and environment.Considering the large area and many points to be monitored in a contaminated site under remediation in Hefei City,the UAV aerial survey technology was used to periodically collect the videos and photos of the site.After a series of standardized processing of the data including the attribute information of site,a realistic 3D model and a database of the remediated site were established respectively.Based on Cesium open source GIS technology,a 3D visual display platform has been built to integrate,release and display various remediation results,providing solutions for dynamic monitoring and 3D data visualization of the site.
