摘　　要：水下测量是测绘工作的一个重要组成部分,利用水下测量技术可获取水下地形、河道纵横断面、水深等数据,保障水域施工、水下救援、河道疏浚等工作的正常开展。相较于传统的人工水下测量手段,搭载声呐设备的无人船水下测量系统以其测量速度快、人工成本低、安全系数高、精度高等特点迅速成为水下测量工作所使用的主流技术,并在很多项目中开展应用。在应用过程中发现,无人船测量环境较为复杂,一般的技术流程往往难以满足实际需要。因此,本文从单波束无人船的测量原理出发,结合实际案例,探讨单波束无人船在复杂水域地形测量中存在的问题及解决方式,形成无人船在复杂水域地形测量的技术流程。Underwater surveying is an important part of surveying and mapping work.Underwater surveying technology can be used to obtain data such as underwater terrain,river cross-section and water depth,to ensure the normal development of water construction,underwater rescue and river dredging.Compared with the traditional artificial underwater measurement method,the unmanned ship underwater measurement system equipped with sonar equipment has quickly become the mainstream technology used in underwater measurement work due to its fast measurement speed,low labor cost,high safety factor,and high accuracy.It was applied in many projects.In the application process,it was found that the unmanned ship measurement environment is more complicated,and the general technical process is often difficult to meet the actual needs.Therefore,based on the measurement principle of single-beam unmanned ships and practical cases,this paper discusses the problems and solutions of single-beam unmanned ships in complex water terrain measurement,and forms the technical process of unmanned ships in complex water terrain measurement.
