Reconnaissance and attack method and system for accurately identifying and disposing underwater dangerous objects and integrated underwater vehicle

The invention discloses a reconnaissance and attack method and system for accurately identifying and disposing underwater dangerous objects and an integrated underwater vehicle, and belongs to the technical field of ocean safety. The method comprises the following steps: acquiring sonar image data of a target area; preprocessing the sonar image data, and eliminating noise and clutter; performing target feature extraction on the preprocessed sonar image data to obtain a clear target highlight area and a shadow area; detecting a detection target; performing preliminary classification and advanced recognition on the feature map subjected to target inspection to obtain an accurate target recognition result; and outputting an identification result, and then adopting a launching system carried on the aircraft to dispose the target. According to the invention, whether the target is the mine or not is judged through the position mapping relation between the target and the shadow in the acoustic image, and a positive
