A Remote Sensing Detection and Positioning Method for River-bottom Tunnels Constrained by Boundary Heat Exchange

Abstract

The invention discloses a river channel remote-sensing detection positioning method under boundary heat exchange constraints, and is applied to the crossing field of thermophysics, remote sensing andmode recognition. The method includes obtaining an underwater target boundary heat exchange constraint model by analysis; performing simulation of a boundary heat exchange constraint model of an underwater tunnel in a river, and verifying boundary heat exchange constraint conditions by a simulation result; and taking an infrared image to be recognized for example, performing image preprocessing, roughly determining a suspected underwater target area and performing accurate positioning of an underwater target. The river channel remote-sensing detection positioning method under boundary heat exchange constraints realizes boundary heat exchange constraint simulation modeling in a river environment, and realizes accurate inversion of the underwater target through the boundary heat exchange constraint conditions, thereby realizing detection and positioning of the underwater target.

Description

Technical field [0001] The invention belongs to the cross field of thermophysics, remote sensing and pattern recognition, and more specifically relates to a remote sensing detection and positioning method for river bottom tunnels under the constraint of boundary heat exchange. Background technique [0002] There are a large number of underwater targets in the river and marine environment, such as underwater tunnels, submarines in the ocean, underwater sunken ships and underwater fish schools. These underwater targets are extremely important both military and economically, so how to accurately detect and locate the location of underwater targets is of great significance. Infrared remote sensing detects underwater resources and environment, and serves the exploration of underwater tunnels, underwater submarines, ocean and seabed resources, and seabed volcanoes and hot springs. Traditional detection methods require a lot of manpower, material and financial resources, and are not su...
