摘要 以日照—京博(日京)管道工程为例,从遥感数据采集、监测内容提取2个方面,开展无人机遥感技术在线型工程水土保持监测中的应用研究。首先,在航摄基础上,利用Agisoft PhotoScan软件处理航摄影像生成高精度的正射影像(DOM)和数字高程模型(DEM);然后基于DOM和DEM成果提取各类监测数据,并构建三维模型。结果表明,利用无人机遥感技术可获取研究区防治措施落实情况、位置、面积、体积等定性和定量数据,监测精度满足相关技术要求。无人机遥感技术应用于线型工程水土保持监测中优势明显,可提高监测工作质量和效率,提升监测信息化水平,为水土流失防治提供技术支撑。

Abstract Taking the pipeline project of RizhaoJingbo (abbreviation as Rijing) as an example, then a research of unmanned aerial vehicle (UAV) remote sensing technology applied in line monitoring was carried out. The contents include remote sensing data collection and monitoring content extraction. Firstly, the Agisoft PhotoScan software was used to process aerial photography image to obtain the highprecision Digital Orthophoto Model (DOM) and Digital Elevation Model (DEM) based on the basis of aerial photography. Secondly, a series of monitoring data were extracted based on DOM and DEM results. Finally, a threedimensional model was constructed. The results showed that using the UAV remote sensing technology can obtain the qualitative and quantitative data, including implementation of control measures, location, area and volume of the research area, and the monitoring accuracy can meet the technical requirements. The UAV remote sensing technology had obvious advantages in monitoring soil and water conservation of linear engineering. It can not only improve the quality and efficiency of monitoring work, but also improve the level of monitoring information,and provide technical support for soil erosion control measures.

水土保持监测是水土流失预防和治理的基础,是生态环境保护和修复的重要工作[1],是国家生态文明建设决策和考核的依据[2]。十九大以来,生态文明建设已经上升为新时代中国特色社会主义的重要组成部分,这对水土保持监测工作提出了更加严格的要求。传统监测手段以调查监测和地面观测为主,针对性强,但监测效率低、精度差[3],难以实现全域监测。卫星遥感影像一般适用于大尺度监测,影像质量易受云层、雾霾等影响[4],对生产建设项目水土保持监测,其影像分辨率不高,无法满足水土保持监测工作的精度要求[5]。……
