摘　　要：使用倾斜摄影测量技术选取港口地区具有代表性的三块涉水条带状地形(如延伸入海的防波堤、LNG码头等)作为研究区开展对比研究,经过数据采集、空三解算后生成实景三维模型,通过对航线布设、像控点布设、空三解算精度、模型精细程度四个方面的综合对比分析,总结出适用于被大范围水域包围的条带状地形的数据采集方法。本研究具备较强的实操性,可得到高精度的实景三维模型,提高作业效率和模型精度,为类似的倾斜摄影测量技术应用场景提供新的技术支持和参考借鉴。UAV oblique photogrammetry is used to compare and study three typical wading strips at harbor,including the breakwater going toward sea,LNG wharf and etc.A real 3D model is built through the processes of data gathering and aerial 3D solution.And a comparative analysis is carried out from the aspects of air route layout,the arrangement of photo control points,the accuracy of aerial 3D solution and model fineness,which produces a data gathering method suitable for the strip terrain surrounded by large water area.This research has high practicality,supports high-precision of real 3D model,leads to improved efficiency and model fineness.In addition,the conclusion presents important references and technical assistance for similar scenarios where UAV oblique photogrammetry is applied.
