Research and Realization of 3D Scene Modeling in Chemical Industry Park

针对化工园区大气监测数据的可视化问题,研究化工园区三维建模的方法,实现基于GIS遥感数据和传感器监测数据的、可远程Web登录的、逼真的化工园区三维可视化信息管理系统。对于楼房等简单对象,采用基于GIS数据的快速建模;对于化工装置等复杂对象,采用3dsMax和无人机倾斜摄影技术相结合的方式建模;在可视化方面,采用基于Cesium的网页前端开发技术。通过结合使用以上的建模方法,减少了大量简单对象建模的重复工作,提升了复杂对象的建模效率,降低了化工园区三维场景建模的难度。

Aiming at the visualization of atmospheric pollution monitoring data in chemical parks,the method of 3D modeling in chemical industry parks is studied,and a remote-web-login and realistic three-dimensional visual information management system based on GIS remote sensing data and sensors' monitoring data is realized.For simple objects such as buildings,rapid modeling based on GIS data is used;for complex objects such as chemical devices,3ds Max and UAV tilt photography are combined to model;in terms of visualization,Cesium-based web front-end development technology is adopted.By adopting the above modeling methods in combination,not only the repetitive work of modeling a large number of simple objects is reduced,but also the modeling efficiency of complex objects is improved. Overall,the difficulty of modeling the 3D scene of chemical industry parks is reduced.
