The invention discloses an underwater composite bionic detection system and a detection target fusion recognition method. The system includes an underwater laser detection module, an artificial side line sensing module and an electric-field detection communication module. Information collected by the laser detection device is utilized for close-range high-accuracy ranging, orientation and underwater-target imaging; water flow and water pressure information collected by the artificial side line device is utilized for obtaining relative speed and depth of a vehicle and locating an underwater vibration source; the electric-field detection communication device is utilized for obstacle detection and underwater communication, and through information fusion of sensing units of the three types ofdetection systems and information interaction among multiple vehicles, the fusion recognition method based on a deep neural network is finally used for providing a guarantee for executing a complex task through cluster control of the underwater vehicles. A high-precision autonomous-detection function of the underwater vehicles is realized through collaborative information obtained by the differentdetection systems, and a new idea and way are provided for marine cluster detection of the underwater vehicles.
Description
technical field [0001] The invention belongs to the technical field of underwater vehicle detection, and in particular relates to an underwater composite bionic detection device and a detection target fusion recognition method. Background technique [0002] As the shortage of land resources becomes more and more obvious, countries around the world pay more and more attention to the research and development of oceans. Among them, underwater vehicles have been widely used in underwater target search and marine resource detection. In practical applications, how to improve the performance of underwater detection systems in complex underwater environments is a key issue. At present, the traditional single underwater detection methods such as sonar and electromagnetic field have very large limitations due to the influence of their physical field characteristics. In recent years, researchers have been inspired by the way fish obtain information underwater, and simulate the percep...
