Problems solved by technology
[0002] In road tunnels, railway tunnels and cable tunnels, since the tunnels are located underground or in mountains, the tunnel wall is prone to water leakage, and at the same time, the cables laid in the tunnels will also experience high temperature and overheating. normal operation of the
At present, the main detection method is manual regular inspection, but manual inspection cannot accurately judge the operation status of the cable, and it is also difficult to analyze and extract the characteristics and area of the tunnel water leakage area, and the speed of manual inspection is slow and it is difficult to achieve rapid detection

The present invention belongs to the field of non -destructive detection technology, and a tunnel detection method based on the two -eyed vision is released, including the following steps: 1) Enter the temperature of high temperature alarm threshold temperature, and establish the infrared thermal image and visible light data that establish a normal without leakage wall surface.Model; 2) Take the infrared thermal image and visible light thermal image map of the wall of the tunnel; 3) The temperature statistics of the infrared thermal image is determined whether there is a high temperature area for high temperature alarm;Like the leakage area in the figure; 5) the leakage area of the infrared thermal image and the visible light thermal image extracting area is extracted as the final leakage area extraction figure;Water area.The present invention uses both infrared thermal imaging technology and visible light imaging technology to combine the advantages of the two to achieve better leakage area extraction effects.
Description
technical field [0001] The invention belongs to the technical field of non-destructive testing, and more particularly, relates to a tunnel detection method. Background technique [0002] In road tunnels, railway tunnels and cable tunnels, because the tunnel is underground or in a mountain, the tunnel wall is prone to seepage of water, and the cables laid in the tunnel will also experience high temperature and overheating, which will affect the tunnel. serious impact on normal operation. At present, the main detection method is manual regular inspection, but manual inspection cannot accurately judge the running state of the cable, and it is also difficult to analyze and extract the characteristics and area of the leakage area of the tunnel, and the speed of manual inspection is slow and it is difficult to achieve rapid detection. . SUMMARY OF THE INVENTION [0003] In view of the above defects or improvement requirements of the prior art, the present invention provide...
