| titleOfInvention | Method, system and application of seabed gas plume processing in multi-beam water column data |
| abstract | The invention belongs to the technical field of marine surveying and mapping and marine detection, and discloses a method, system and application for extracting seabed gas plumes in multi-beam water column data. The gas or gas-liquid mixed water body will produce a larger gas flow than the normal water body environment. Acoustic impedance, which provides the possibility to use the scattering information of the water body to identify the gas plume. Analyze and extract multi-beam raw data, use the extracted ship position coordinates and heading, survey ship attitude information and other information to calculate and obtain various multi-beam WCIs and perform 3D reconstruction based on their spatial references to construct 3D points based on water body acoustic scattering information cloud model. Using imaging methods to achieve WCI noise reduction, filtering, and binarization to initially separate the plume part data from the overall water body point cloud; introduce Kmeans and local anomaly factor data mining algorithms into water body information processing to ensure plume flow as much as possible On the basis of preservation, further denoising can improve the extraction effect of plume flow. |
