摘　　要：海洋强国是十八大以来我国重要的战略部署。海岸线作为海陆分界的重要依据,在海洋发展中起着不可或缺的作用。针对海岸线无人机倾斜照片利用效率低的问题,本文以2019年广东省海岸线修测项目为例,基于无人机定位定姿系统(POS)数据模拟无人机拍摄瞬时飞行状态,通过程序实现自动获取无人机可视域分析算法,可自动筛查、分析、计算无人机倾斜照片可视域,与海岸线要素进行空间叠加分析,为海岸线定位、定性、复核工作提供支持。The maritime power has been an important strategic deployment of our country since the 18th National Congress of the Communist Party of China.The coastline,as an important basis for the demarcation between the sea and the land,plays an indispensable role in the development over the ocean.To deal with the problem that the utilization efficiency of unmanned aerial vehicles(UAVs)on the coastline has been low,this paper performed a case study on the Guangdong Coastline Survey and Revision Project in 2019.Based on the POS data of the UAV tilt photographs,A set of algorithms for automatic acquisition and analysis of the UAV field of view was implemented through the program.Such UAV visual field algorithm automatically screens,analyzes,and calculated the UAV visual field.The visual field elements and coastline elements were then analyzed through spatial superposition to support the positioning,classifying,revising,and review of the coastline.
