Development of UAV Low-altitude Remote Sensing Technology and Its Application in Industry

本文主要针对无人机低空遥感技术发展现状及行业应用进行综合性论述。其中,无人机低空遥感的主要特点从航摄效率、影像分辨率、数据处理、主要缺点等4个方面进行论述,遥感影像处理主要流程包括影像预处理与影像重叠度计算、空中三角测量、影像生产与制作、质量检查。行业具体应用方面,则以大比例尺地形图测绘、国土资源监测、应急监测等方面进行论述。文章最后对无人机遥感应用进行展望并给出行业发展的一些建议。

This paper mainly focuses on the comprehensive discussion of the status quo of UAV low-altitude remote sensing technology and industry application. Among them, the main features of UAV low-altitude remote sensing are discussed from four aspects： aerial photographing efficiency, image resolution, data processing, major shortcomings. The main processes of remote sensing image processing include the calculation of image preprocessing and image overlap, aerial triangulation, image production and production, quality inspection.Specific industry application is discussed from the large-scale topographic mapping, land resources monitoring, emergency monitoring and so on. Finally, the article forecasts the application of UAV remote sensing and gives some suggestions for the development of the industry.
