无人机摄影测量在水体污染评估中的应用

Application of Unmanned Aerial Vehicle Photogrammetry to Water Quality Assessment

无人机摄影测量是一种快捷、准确的测量技术,在测绘与空间信息行业得到越来越广泛的应用。本文针对水库库区的水体污染现状,探讨利用小型无人机进行摄影测量,并采用多视图几何理论与光束平差方法,以及空三解算模型进行影像处理,从而测量评估水体中的特定污染物分布情况,并以广东省梅州市青溪库区水浮莲污染调查为例进行污染分布的研究,为水库治理提供依据。

UAV photogrammetry in surveying and mapping is a quick and accurate measurement technology.In this paper,for assessing the degree of pollution in reservoir,a small UAV photogrammetry system is used to investigate the area of water lettuce pollution in Qingxi Reservoir of Meizhou City.Related methods and test results have formed basis for the reservoir management.
