Abstract: This article introduces the working principle of the unmanned surface vessel (USV) bathymetric system and the Huawei 3 USV bathymetric system. It explores the application of the USV bathymetric system in underwater topographic surveying, evaluates the internal depth measurement consistency of the system using the check line method and the overlapping profile method, and assesses the external depth measurement consistency through the overlapping profile method and DEM raster operations. By conducting comparative analysis, the reasons for depth measurement discrepancies between the two bathymetric systems are examined, providing a research foundation for the application of USV bathymetric systems in underwater topographic surveys of river channels in complex waters.
