基于无人船的水陆一体化测量技术研究与应用

Research and Application of Water and Underwater Integrated Measurement Technology Based on Unmanned Ship

海岛(礁)、近岸和码头等水陆结合部一直是海洋测绘的困难区域,且存在较大安全风险。针对传统地形测量方法难以满足水陆结合部测量需求和精度要求的问题,研制了一种基于无人船的水上水下一体化测量技术。利用该技术对码头、岛礁、水中建筑物等进行了一体化测量,并对获得的水上水下点云数据成果进行了精度分析,验证了该技术在实际工程中的有效性,具有一定的工程意义。

Land and water junctions such as islands(reefs),near shores and docks have always been difficult areas for marine surveying and mapping,and the measurement difficulty coefficient is high.In view of the difficulty of traditional topographic surveying methods to meet the measurement requirements and accuracy requirements of the land and water junctions,we developed a water and underwater integrated measurement technology based on unmanned ship.We used this technology to perform measurements on docks,islands,reefs and underwater structures,and analyzed the accuracy of obtained water and underwater point cloud data results.The results demonstrated the effectiveness of this technology in actual engineering.
