Problems solved by technology

However, the existing road tunnel fire monitoring methods use video surveillance cameras to obtain video (visible light) images, and "bright spots" will appear in the accident images collected under strong light environments such as tunnel fire accidents, and it is impossible to effectively obtain tunnel fire accident images. The location information of the occurrence makes it difficult to determine the scale, specific location, number of casualties and other specific accident information of the tunnel fire accident based on visible light images, which makes it difficult to effectively carry out rescue work, resulting in poor monitoring of road tunnel fires

[0066] The laser radar unit can be realized by a laser radar probe and other structural units, and is used to obtain the three-dimensional scanning image or cloud point image of the t...

Embodiment 2

[0078] On the basis of the first embodiment, this embodiment discloses a fire monitoring method for a road tunnel based on image fusion.

[0079] Such as Figure 4 As shown, the road tunnel fire monitoring method based on image fusion is implemented based on the road tunnel fire monitoring system in Embodiment 1, and specifically includes the following steps:

[0080] S1: Obtain visible light images of tunnel fire accidents;

[0081] S2: Obtain a thermal imaging image and a three-dimensional scanning image at the corresponding position where the visible light image is obtained;

[0082]S3: Through image fusion processing, firstly, the thermal imaging image is fused into the visible light image to obtain the corresponding color fusion image, and then the 3D scanning image is fused into the color fusion image to obtain the corresponding 3D color fusion display image, and the fusion processed The 3D color fusion display image is used for fire monitoring in highway tunnels; the ...

Abstract

The invention particularly relates to a highway tunnel fire monitoring system and method based on image fusion. The system comprises a camera unit used for acquiring a visible light image of a tunnel fire accident; an infrared scanning unit used for acquiring a thermal imaging image of the tunnel fire accident and the surrounding environment; a laser radar unit used for acquiring a three-dimensional scanning image of the tunnel fire accident and the surrounding environment; and an image fusion display unit used for fusing the thermal imaging image into the visible light image and then fusing the three-dimensional scanning image into a color fusion image to obtain a three-dimensional color fusion display image containing information such as temperature, distance, coordinates and the like for highway tunnel fire monitoring. The invention also correspondingly discloses a highway tunnel fire monitoring system and method. According to the highway tunnel fire monitoring method, accident information images can be effectively acquired in severe environments such as low visibility and strong light, so that important rescue guidance can be provided, and the monitoring effect of highway tunnel fire monitoring can be improved.

Description

technical field [0001] The invention relates to the technical field of tunnel safety management, in particular to a road tunnel fire monitoring system and method based on image fusion. Background technique [0002] In recent years, with the improvement of national infrastructure, the number of road tunnels has increased. The traffic flow inside the highway tunnel is relatively large, and there is a big difference between the lighting inside the tunnel and the outside of the tunnel, which leads to tunnel fire accidents such as collisions and scratches during driving inside the tunnel. At the same time, due to the particularity of the tunnel, the efficiency of accident rescue inside the tunnel is low. At the same time, it is difficult for external vehicles to obtain the tunnel road condition information at the first time. Once an accident occurs in the tunnel, the casualties and losses will be even more serious. Therefore, the safety monitoring of highway tunnels is particula...
