Mountain strip-shaped underground tunnel inversion detection positioning method and device

Abstract

The invention provides a mountain strip-shaped underground tunnel inversion detection positioning method and device, and belongs to the crossing field of geophysics subject theory and remote sensing technology, and the method comprises the steps: employing a thermal radiation model between a mountain and an air layer, combining DEM data, calculating solar radiation energy, and carrying out the iteration filtering of mountain background heat flow field energy; calculating the heat propagation energy of the mountain background in combination with the hyperspectral data; an underground target inversion model is adopted, background heat flow field energy of each layer of the mountain is filtered out in the infrared remote sensing image, and the optimal altitude of the strip-shaped underground tunnel in the mountain and a disturbance signal distribution image constructed by the heat flow field energy of the strip-shaped underground tunnel in each layer of the mountain are obtained; detecting a straight line in the disturbance signal distribution image by using a Hough transform detection method, and fitting to obtain a detection position of a tunnel according to a relevance principle of tunnel engineering design; the inversion detection positioning of the strip-shaped underground tunnel in the mountain environment is realized.
