| 海岸线修测工作中，现场获取的无人机照片和视频是海岸线类型研判和内业处理的重要依据，也是海岸线修测工作的重要数据成果。本文以广东省海岸线修测工作为例，介绍了海岸线修测外业工作中无人机照片和视频的获取及预处理方法，并采用ArcGIS二次开发方式，构建了一套面向海岸线修测的无人机照片视频管理系统。该系统实现了无人机照片视频文件的批量自动入库、无人机照片位置和视频轨迹的自动提取、无人机单张正射照片的快速地理定位和无人机照片视频的快速查询浏览。最后，基于无人机照片视频位置与修测海岸线的空间关系，自动挂接每个岸段对应的无人机照片和视频，并批量导出满足要求的照片视频成果。 |
| 英文摘要: |
| The UAV photos and videos obtained on site are the important basis of coastline type judgment and interior work processing, and also the important data results in the work of coastline survey. Taking the coastline survey work in Guangdong Province as an example, this paper introduced the acquisition and preprocessing method of UAV photos and videos in the coastline survey, and constructed an UAV photos and videos management system by using the development of ArcGIS. The system realized the automatic storage of UAV photos and video files in batches, the automatic extraction of UAV photo locations and video tracks, the quick geographical location of UAV single orthophoto and the quick query and browsing of UAV photos and videos. Finally, based on the spatial relationship between the location of UAV photos and videos and the coastline, the UAV photos and videos are linked to each coastline section automatically, and can also be exported in batches. |
