%X 无人机航测技术以高精度、高分辨率、高采集速度等明显优势被广泛应用在测绘领域的各个方面。本文结合洞庭湖四口河道测量项目，对以耕地、密林、芦苇、草地等多层次、高密度植被覆盖为特征的陆域部分开展了相关技术的应用，并对其观测精度进行了检测分析。结果表明，精度符合相关规范要求，以无人机航测技术获取高分辨率的DOM与高精度的DEM数据，并对其进行融合生产DLG及其他一些产品，为洞庭湖四口水系的陆上河道测量提供了技术支撑。<br />
Unmanned aerial vehicle surveying technology is widely used in various aspects of surveying and mapping due to its obvious advantages such as high accuracy, high resolution, and high acquisition speed. In the measurement project of the four inlets channels in Dongting Lake, relevant technologies were applied to land areas characterized by multi-level and high-density vegetation coverage such as farmland, dense for-ests, reeds, and grasslands, and the observation accuracy was tested and analyzed. The results indicate that the accuracy meets relevant specification requirements. This paper obtained high-resolution DOM and high-precision DEM data using drone aerial survey technology and produced DLG and other products, which provided technical support for the onshore river channel measurement of the four inlets systems in Dongting Lake.
