无人船在海洋水下地形测量中的应用和数据处理

Application and Data Processing of Unmanned Vehicle in Underwater Topographic Survey

水下地形测量是测量江河、湖泊、水库、港湾和近海水底点的平面位置和高程,用以绘制水下地形图的测绘工作。通过使用无人船搭载单波束测深仪、多波束测深仪、ADCP声学多普勒流速剖面仪、水质仪等多种数据采集设备进行海洋水下地形测量,可有效解决传统作业方式效率低下,受地形环境等因素限制较大的情况,能够满足传统测量方式难以完成的作业和工期要求。本文结合项目实际,通过无人船在海洋水下地形测量中的应用和数据处理研究,建立了完整的技术流程,得到符合精度要求的海洋水下地形测量成果数据。

Traditional underwater topographic survey mainly uses RTK,charter boat and kayak.Unmanned ship carries single-beam bathymeter,multi-beam bathymeter,ADCP acoustic Doppler velocity profiler,water quality meter and other data acquisition equipment to carry out underwater topographic survey,which can effectively solve the inefficiency of traditional methods of operation and greatly restricted by topographic environment,and can meet the requirements of operation and time limit that traditional methods of measurement are difficult to complete.In this paper,based on the actual project,through the application of unmanned ship in underwater topographic survey and data processing research,a complete technical process is established,and the results of underwater topographic survey in line with the accuracy requirements are obtained.
