多旋翼无人机航测系统在高原地质灾害中的应用
|
摘要
多旋翼无人机航测系统以其机动灵活、高效快速、精细准确、作业成本低、适用范围广、生产周期短等优势逐渐成为传统摄影测量的有力补充。多旋翼无人机航测系统在德钦县民族小学后山滑坡群进行高空间、高分辨率的遥感探测,获取高分辨率影像,采用Agisoft Photo Scan软件进行数据处理,利用生成的大比例尺数字正射影像图(DOM)和数字高程模型(DEM)辅助对比分析,实现高原山区地质灾害区域的变化监测,为滑坡的预防、预测和评估提供基础数据和技术保障。
The aerial photogrammetry system of multi rotor unmanned aerial vehicle( UAV) for its flexibility,fast and efficient,accurate,low cost,wide application range,short production cycle has become a powerful complement to traditional photogrammetry system. The aerial photogrammetry system of multi rotor unmanned aerial vehicle carries out high spatial and high resolution remote sensing for landslide groups in the mountain behind national primary school of Deqin County and acquires high resolution images. Agisoft Photo Scan software is used for data processing,and using the largescale digital orthophoto map( DOM) and digital elevation model( DEM) to compare and analyze.It can realize the monitoring of the change of geological disaster area in plateau mountain area,and provide basic data and technical guarantee for landslide prevention,prediction and evaluation.
