Latest Patents

Wenxue Xu holds a patent for an "Identification method of seabed weak echoes by airborne LiDAR bathymetry and system thereof." This invention provides a novel approach to identifying seabed weak echoes in airborne LiDAR bathymetry. The method involves dividing sea area laser pulses into surface-seabed pulses or seabed-undefined pulses based on preprocessed data. It utilizes a two-stage local maximum method to determine potential seabed echo positions of ALB waveforms and pre-generates seabed points. Furthermore, it defines an ellipsoid neighborhood related to density and extracts spatial features of a pre-generated point cloud. A BP neural network is constructed to identify seabed points in the pre-generated point cloud, optimizing the identification result based on a laser pulse echo sequence and point cloud density. This patent showcases his innovative approach to enhancing marine surveying techniques.
