System and method for searching and positioning missing person by underwater robot

Abstract

The invention provides a system and method for searching and positioning a missing person by an underwater robot, and the method comprises the steps of carrying out the large-range searching operationin a disaster region in a cableless operation mode through employing autonomous detection and a side-scan sonar and a processing system control cabin of the side-scan sonar, and obtaining the underwater position information of suspected missing persons with different confidence rates. In a cabling operation mode, fine search is carried out in each suspected area according to the target confidenceof the suspected missing person from high to low, personnel on the ship observe underwater optical and acoustic images uploaded to a mother ship in real time, and fine missing person search operationis carried out through man-machine cooperative judgment. The invention is an efficient and multi-method matched detection means, the underwater condition can be detected under the severe and complexwater body condition, so people in distress can be positioned in time through the means of area investigation, man-machine cooperation, chemical reagent sniffing tracking and the like, and a foundation is laid for further rescue.

Description

technical field [0001] The invention relates to a system and method for searching and locating missing persons by an underwater robot, belonging to the field of underwater detection and rescue. Background technique [0002] With the continuous development of the economy, the efficient use of energy and resources has gradually become a hot topic of discussion. my country has a vast territory and is especially rich in water resources. Using water resources for shipping, production, and power generation has become a very common way. Among the many water resource utilization methods, sea routes connect various countries and regions and have the function of communicating with the world; as a branch of hydraulic engineering, dams have the functions of flood control, water storage, water supply, and power generation. However, various shipping accidents and dam collapse accidents occur from time to time around the world. When accidents occur, people are often lost in distress. Howev...

Problems solved by technology

However, various shipping accidents and dam collapse accidents occur from time to time around the world. When accidents occur, people are often lost in distress. However, the uncertainty of waters and the complexity of hydrological conditions will cause turbidity and visibility in nearby waters. Inferior problems, underwater cameras are difficult to perform long-distance search work, and ordinary underwater light vision is no longer suitable for emergency rescue situations
