摘　　要：针对我国远海岛礁高分辨率立体测绘的实际困难,本文提出了一种利用轻小型无人机开展远海岛礁高分辨率影像获取与无控测图的测绘技术方法。该方法研究解决轻小型无人机远距离飞行与全航程监控、顾及远海岛礁特征的无人机航摄规划设计,以及无控测图等关键技术。通过远海海岛影像获取及处理实验,验证了其能满足远海岛礁航测成图的技术要求,可为我国开展远海岛礁测绘工程化应用提供新的解决方案。In view of the practical problems in high-resolution stereo mapping of offshore islands or reefs in China,this paper proposes a mapping technology method for high-resolution image acquisition and uncontrolled mapping by using small and light UAVs.This method studies and solves the key technologies,such as Long distance and full range flight monitoring,the planning and design of aerial photography considering the characteristics of remote islands or reefs,and uncontrolled mapping of small and light UAVs.Through several experiments of image acquisition and processing of offshore islands,it is verified that this method can meet the technical requirements of aerial mapping of offshore islands or reefs,and can provide a new solution to the engineering application of mapping of offshore islands or reefs in China.
