Abstract
Disclosed is a sediment classification method and system based on bottom echo information of a deep-sea multibeam water column, falling within the technical field of seabed sediment classification. Multidimensional features of seabed multibeam time series are extracted by using multibeam water column data, and multidimensional features of seabed spots are constructed by fusing an angle response curve; double-waveform spectrum comparison of original sample point waveform with seabed measured point waveform is performed, and two groups of corresponding waveforms are matched by using Cosine Similarity to expand original sample points; and the reliability of classification results is improved. In the present disclosure, the transformation from hard to soft classification is realized, and the seabed habitat inversion of complex mixed sediment in a deep sea is further realized.
