无人机航测系统的海岛礁测绘应用研究

介绍了三型基于无人飞行器为平台的航测系统,分析了影响海岛区域无人机影像数据处理精度的因素,无人机航测系统在海岛区应用的技术特点。以该三型系统在我国某海岛区域进行了摄影作业,对实验数据质量、空中三角测量精度、正射影像精度等进行分析。实验结果表明,无人机低空航测系统在海岛区域大比例尺地形测绘或海图修测等领域具有良好的应用前景。

Research on UAV Photogrammetric Systems in Areas of Islands and Reefs

Three kinds of the unmanned aerial vehicle(UAV) photogrammetric systems are introduced,as well as the captured images based on these three kinds of UAV photogrammetric systems in some areas of islands and reefs. The factors that affecting the accuracy of UAV image data processing and the characteristics of UAV photogrammetric systems used in island areas are analyzed. Lastly,we processes the image data through image quality analysis, aerial triangulation and making digital orthophoto map. The experiment shows the UAV photogrammetric systems has a great application perspective in the field of terrestrial photogrammetry and chart updates in island areas.
