Abstract: Multi-beam sounding technology provides a high-precision, high-efficiency and high-resolution 3D representation for seabed topography surveying, which is a necessary implementation of the national marine strategy. However, the complexity and uncertainty of the marine environment brings significant challenges to the collection, processing and analysis of seabed topographic information. The quality of 3D visualization depends on the advancement of data acquisition hardware, computer software and graphic processing algorithms. Hence, seabed topography demonstrates important theoretical significance and practical research value. This paper discusses the current status of research, advanced algorithms and accuracy assessment in the 3D modeling of seabed topography. Firstly, we outline the latest progress in domestic and international research on seabed topographic 3D modeling and modeling quality evaluation indicators. Then we analyze and compare the performance of three open-source algorithms under the data of a local area in the northwestern South China Sea. Finally, the promising development trends of seabed topographic 3D modeling are summarized.

Key words: multi-beam, seabed topography, 3D modeling, accuracy assessment
