Xi'an, September 9 (Reporter Mei Yilong) The reporter learned from Northwestern Polytechnical University on the 26th that the joint scientific research team composed of the university and the Xi'an Institute of Optics and Fine Mechanics of the Chinese Academy of Sciences and other scientific research institutions has broken through the key technology of multi-quadrant angle optical guidance with longer detection distance, higher accuracy and stronger anti-interference ability, and successfully developed the "Leader" deep-sea optical intelligent guidance system.

According to reports, the joint scientific research team recently carried out the sea trial verification of the "Navigator" deep-sea optical intelligent guidance system at the Beihai Marine Technology Center of the Ministry of Natural Resources of China. Different from the traditional visual guidance technology, the team uses the self-developed area array detector to capture the light intensity of the guidance signal of the recycle station, establish a mathematical model of the declination angle of the guide lamp, and input the measured declination angle data into the self-developed intelligent optical guidance system, and use the intelligent search algorithm to complete the three-dimensional pose solving of the recycle station. The system has an ultra-high detection frequency, which can realize the code identification of the recovery device at the same time, thereby effectively avoiding the misdirection and induction of the underwater unmanned underwater vehicle.

It is understood that the joint scientific research team took the operation ship and carried out the guided recovery sea trial operation in the deep-water area, and benefited from the high-speed and accurate three-dimensional pose solving ability of the "Navigator" deep-sea intelligent optical guidance system, successfully obtained the coordinates of the recovery station, guided the underwater unmanned underwater vehicle to correct the course in real time, successfully completed the guidance and recovery, and successfully verified the high-frequency coding detection ability of the system. The team used differential satellite positioning equipment to verify the coordinates of the solved recovery station, and the sea trial reached the predetermined goal.

In this sea trial, the joint scientific research team successfully verified a new high-frequency multi-quadrant angle measurement optical guidance technology, which provides reliable optical guidance equipment support for deep-sea/shallow sea unmanned underwater vehicles, solves the energy supply and data transmission needs of underwater unmanned vehicles, and helps underwater unmanned underwater vehicles expand from shallow sea operations to deep sea operations, from short-term work to long-term residence, from point domain exploration to wide-area development, from single operations to cluster collaborative operations, effectively ensuring "deep-sea access, deep-sea exploration, and deep-sea development." "The mission is efficient, safe and sustainable, which has contributed to the "maritime power" strategy. (End)
