Underwater heat source detection and location method based on water body hierarchical filtering

Abstract

The invention discloses an underwater heat source detection and location method based on water body hierarchical filtering, and belongs to the crossing field of marine science, thermal physics and pattern recognition, the method is used for hierarchically filtering the water body, filtering depth is determined through an optimal criterion, and a specific location of the underwater heat source is accurately reflected. The method comprises a step for thermal radiation simulation of an underwater heat source in a water body, a step for actually measuring and acquiring an infrared image of an underwater target, a step for hierarchically filtering the water body and a step for detecting and locating the underwater heat source. According to the invention, a thermal field model of a hierarchical ocean water body is established, a thermal field model of a simplified underwater heat source including an underwater vehicle is further established, and a result of the thermal field model of the underwater heat source in the water body can prove that thermal radiation of the water body is hierarchically distributed; according to the acquired infrared image and the hierarchical theory of the water body thermal radiation, the water body hierarchical filtering method can be used for performing detection and location of the underwater heat source, and precision of detection and location is improved.

Description

technical field [0001] The invention belongs to the cross field of marine science, thermophysics and pattern recognition, and in particular relates to an underwater heat source detection and positioning method based on water body layered filtering. Background technique [0002] The "21st Century Maritime Silk Road" in my country's "One Belt, One Road" strategy spans a vast ocean space. The national ocean strategy in the new era urgently needs the support of advanced and powerful ocean detection technologies. In recent years, offshore oil exploration, ocean chemistry and marine Industries such as biology provide huge business opportunities for the marine economy. The traditional use of ships to explore marine organisms requires a lot of manpower, material and financial resources, and is not suitable for large-scale searches of underwater organisms. my country's oceanic land is being seriously invaded by many coastal countries, and most of the Nansha islands and reefs have bee...
