测绘无人机在2022冬奥会国家高山滑雪中心工程中的应用

Application Research of Surveying and Mapping UAV in the National Alpine Skiing Center of 2022 Winter Olympics

2022年冬季奥运会延庆赛区,承担多项重大奥运赛事。其中,国家高山滑雪中心承担着最精彩、最惊险的雪上竞速和竞技比赛项目。这些项目要求雪道海拔高,路线长,拐弯急,落差大。最终选址位于燕山群峰之中的小海坨山,其南麓山坡地形符合雪上竞速的严苛标准,但其复杂多变的高山山地地形和落后的交通条件,给工程施工带来极大的困难。如何配合施工,高速高效地完成这些高标准雪道、索道和配套设施的施工任务,是摆在参施测量人员面前的技术难题。本文通过研究对比各种测量手段,采用了测绘无人机低空航摄技术及相关摄影测量软件,较好地完成了国家高山滑雪中心工程山地地形模型的快速获取和快速更新任务。

The 2022 Winter Olympics Yanqing Division has undertaken a number of major Olympic events.Among them,the National Alpine Ski Center is responsible for the most exciting and thrilling snow racing and competitive events.These projects require high altitudes on the slopes,long routes,sharp turns,and large gaps.The site is located in the Xiaohaituo Mountain in the Yanshan Mountains.The southern slope of the mountain meets the criteria for ski racing,However,the complex and varied alpine terrain and backward traffic bring great difficulties to the construction.How to cooperate with the construction,high-speed and efficient completion of these high-standard snowways,ropeways and supporting facilities construction tasks is a technical problem in front of the measurement staff.This paper compares various measurement methods through research,The low-altitude aerial photography technology and related photogrammetry software of the UAV are used to quickly complete the rapid acquisition and rapid update of the alpine model of the National Alpine Ski Center.
