Title:
INFRARED IMAGING DETECTION AND POSITIONING METHOD FOR UNDERGROUND TUBULAR FACILITY IN PLANE TERRAIN
Document Type and Number:
WIPO Patent Application WO/2015/101061
Kind Code:
A1
Abstract:
An infrared imaging detection and positioning method for an underground tubular facility in a plane terrain. Demodulation processing is performed on an original infrared image formed after stratum modulation is performed, of the underground tubular facility according to an energy diffusion Gaussian model of the underground tubular facility, so as to obtain a target image of the underground tubular facility. The method comprises: obtaining an original infrared image g formed after stratum modulation is performed on an underground tubular facility; setting an initial value h0 of a Gaussian thermal diffusion function according to the original infrared image g; using the original infrared image g as an initial target image f0, and performing, according to the initial value h0 of the Gaussian thermal diffusion function, iteration solution of a thermal diffusion function hn and a target image fn by using a single-frame image blind deconvolution method based on a Bayesian theory; and determining whether an iteration termination condition met, and if the iteration termination condition is met, determining the target image fn obtained by means of iteration solution this time to be a final target image f; and if the iteration termination condition is not met, continuing the iteration calculation. By means of the method, the infrared image of the original underground tubular facility is clearer to display, and the real structure of the underground tubular facility can also be inverted.
