Airborne lidar bathymetric systems can not only obtain water bathymetry data, but also obtain laser pulse waveform data containing bottom material information. With the innovation and application of airborne lidar bathymetry technology, its seabed sediment classification function has been continuously developed. The efficiency of seabed sediment classification based on airborne lidar bathymetry waveform data and combined with water bathymetry derived data has been continuously improved. Through the combination of multi-source remote sensing information, the accuracy of seabed sediment classification has also been improved. This article mainly discusses the current situation of airborne lidar bathymetry technology in seabed sediment classification, introduces the basic principles of airborne lidar bathymetry technology, analyzes the main problems in this field, and looks forward to the development trend of research on seabed sediment classification based on airborne lidar bathymetry technology.
