Benefits of technology

[0046]This invention, through the acquisition of detection data from a target sea area, preprocesses the data to obtain depth sounding data and corresponding positioning and attitude data. The detection data includes raw depth sounding data acquired by a lidar system and corresponding raw positioning and attitude data acquired by a positioning and orientation system. The depth sounding data includes depth sounding echoes from various water areas within the target sea area. Waveform decomposition is performed on the depth sounding data, and the target optical path slant range is constructed based on the results. Error correction is applied to the target optical path slant range based on the lidar's internal parameters and the positioning and attitude data, thereby constructing an initial point cloud. Three-dimensional filtering is then applied to the initial point cloud to obtain the target point cloud. This invention proposes a complete refined processing flow for lidar detection data based on lidar depth sounding data. Specifically, it involves waveform analysis of the depth sounding data, error correction of the target optical path slant range, point cloud construction, and final point cloud filtering. Compared to traditional acoustic methods, this invention can comprehensively cover various water areas and effectively avoid the cumbersome processing of multi-source data. This invention can efficiently achieve refined processing of detection data.
