A method for detecting and locating underwater heat sources based on layered filtering of water bodies

Abstract

The invention discloses a method for detecting and locating underwater heat sources based on layered filtering of water bodies, which belongs to the cross field of marine science, thermophysics and pattern recognition, and aims to perform layered filtering on water bodies, and determine the filtering by optimal criteria The depth accurately reflects the specific position of the underwater heat source. The invention comprises the thermal radiation simulation step of the underwater heat source in the water body, the step of acquiring the infrared image of the underwater target through actual measurement, the layered filtering step of the water body, and the detection and positioning step of the underwater heat source. The present invention constructs the thermal field model of the layered ocean water body, and further establishes a simplified underwater heat source including the thermal field model of the underwater vehicle. The results of the thermal field model of the underwater heat source in the water body can prove that the thermal radiation of the water body is Layered distribution; through the obtained infrared image and the layered theory of water body thermal radiation, the underwater heat source is detected and positioned by the method of water body layered filtering, which improves the accuracy of detection and positioning.

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...
