摘要
冬季奥林匹克运动会的雪上项目建在高差悬殊、地形复杂、山高林密的区域,为了因地制宜,减少挖填方,控制资金,场馆设计需要精细准确的现状数据。本文以2022年冬奥会延庆赛区为例,利用无人机遥感、LiDAR技术获取现状数据,制作高分辨率数字正射影像及高精度数字高程模型,搭建实景三维场景,将规划设计方案制作三维模型,导入实景三维场景,进而开展辅助冬奥会规划决策的相关应用。本文成果不仅为冬奥组委会、业主和相关管理部门信息共享提供了切实的技术支撑,也为三维地理信息技术在山区大型工程中的应用提供了有效的方法借鉴,为山区冰雪项目的设计提供了参考。
The snow projects of Winter Olympic Games will be held in areas with complex terrains,high mountains and dense forests.In order to minimize environmental impacts,reduce cut and fill,and to control investment,the design work relies on fine and accurate data.This paper takes the Yanqing Zone of 2022 Beijing Winter Olympics as an example,using UAV remote sensing and LiDAR technology to obtain data.Then,high-resolution digital orthophotos and high-precision digital elevation models are produced to construct 3D scenes,with design model imported.The results of this paper provide practical technical support for the information sharing among the Winter Olympic Organizing Committee,owners and relevant government departments.This paper shows the potential of the application of 3D geographic information technology in large-scale projects in mountainous areas,and can be referenced for the design of mountain ice and snow projects.
