摘　　要：详细介绍了多波束探测系统的组成、多波束探测系统的测量工作原理,总结出测量数据具有显著的大数据量、高密度、离散性等主要特点,并对数据处理流程进行阐述。采用规则网法与Delaunay三角网两种方法分别建立海底三维模型,得出Delaunay三角网建立模型速度更快,细节展示更精准。最后通过不同建模算法的坐标中误差对比可知,Delaunay三角网建模精度更高。This article introduces the composition of a multi-beam sounding system in detail,explains the measurement working principle of the multi-beam sounding system,summarizes the main characteristics of measurement data such as significant large data volume,high density and discreteness,and introduces the data processing process in detail.Using the regular net method and the Delaunay triangular network method,this paper establishes a three-dimensional model of the seabed,and concludes that the Delaunay triangular network is faster to establish a model and more accurate to display details.Finally,by comparing the errors in the coordinates of different modeling algorithms,it can be seen that the Delaunay triangular network has higher modeling accuracy.
