Problems solved by technology
However, the above two existing methods have the following defects: the underwater optical detection method is easily affected by the turbidity of water quality, and cannot accurately obtain the specific information of the underwater vibration source, and the image processing process of this method is cumbersome, which limits its application Underwater information perception ability in turbid and dark environment
The underwater acoustic detection method is easily affected by the acoustic multipath effect and various environmental interference noises, which makes this method unable to accurately perceive the information in the underwater environment.
[0003] Therefore, the existing underwater optical detection methods and underwater acoustic detection methods cannot accurately detect underwater vibration source information due to the influence of the external environment.
