Ship bottom target identification method and system

Abstract

The invention discloses a ship bottom target identification method and system. According to the method, a mode of combining three-dimensional sonar and an underwater robot is adopted. When the underwater robot is placed, the three-dimensional sonar guides the underwater robot to the position near a suspicious target, the underwater robot is controlled to dive to the position of the depth of the suspicious target, and close-range optical imaging identification and confirmation can be performed on the suspicious target through an underwater camera. Simultaneously, in the system, the three-dimensional sonar is installed on an identification ship through a cradle head, the sonar can move along with the identification ship, a monitoring area of the system is broadened, and accordingly detection is performed on a suspicious ship on the sea surface without being limited to the positions of ports, dams and ship locks and the like. Simultaneously, the sonar can be driven by the cradle head to rotate, the detection area of the sonar is broadened, and thoroughness of bottom detection of the suspicious ship is guaranteed.

Description

technical field [0001] The invention relates to a method and a system for identifying a target at the bottom of a ship. Background technique [0002] As the international strategic situation changes, hostile conflict patterns are also constantly evolving. The occurrence of the "9.11 Incident" has completely changed the traditional way of terrorist attacks, and the characteristics of diversification and concealment have become increasingly prominent. Maritime security has become an important part of international anti-terrorism operations. River dams and ports are important water conservancy and military facilities in my country. There are many ships passing by, so their protection is becoming more and more important. At present, although such areas have perfect land and water security inspection measures, the security inspection methods for the part of the ship below the water surface are extremely scarce. After terrorists control civilian ships, once underwater explosives...
