摘要
无人机倾斜摄影测量系统作为一项新兴的测量技术,可以快速准确获取航测区域内的地理信息数据。近年来无人机倾斜摄影测量技术在工程测量、房产测量、地籍测量等方面得到了广泛的应用。本文以黑龙江某地区抽水蓄能电站为例,简单介绍了无人机倾斜摄影测量技术在水库库容量算过程中的应用,生产的点云数据经过数据组织、抽稀简化、噪声去除等处理后,应用GIS技术,自动计算水库库容量。通过与传统方法对比分析,结果显示无人机倾斜摄影测量技术在水库库容量算中不仅缩短了工作周期,也提高了量测精度,为今后水库库容量算提供了一种新的计算方法。
Taking a Pumped Storage Power Station in Heilongjiang province as an example,this paper introduces the application of UAV tilt photogrammetry technology in the calculation of reservoir capacity.The production point cloud data is processed by data organization,thinning and simplification,noise removal,etc.,and the reservoir capacity is automatically calculated by using GIS technology.Compared with the traditional method,the results show that the UAV tilt photogrammetry not only shortens the working period,but also improves the measurement accuracy,which provides a new calculation method for the reservoir capacity in the future.
