Embodiment Construction

[0033] The present invention will be further described below in conjunction with accompanying drawing.

[0034] figure 1 A tunnel surface quality defect detection system according to an embodiment of the present invention is schematically shown. According to the tunnel surface quality defect detection system of the present invention, it can automatically collect and process the image information of the tunnel surface, identify the tunnel surface quality defects, and fill the tunnel with light in all directions, so that the collected image information is clearer, so that the detection results more precise.

[0035] Such as figure 1 As shown, the tunnel surface quality defect detection system described in this embodiment includes an imaging system 1 . The imaging system 1 is used for collecting and displaying image information of the tunnel surface. The tunnel surface quality defect detection system described in this embodiment also includes a supplementary light device 2, w...

Abstract

The invention relates to a tunnel surface quality defect detection system, and belongs to the field of tunnel engineering. The tunnel surface quality defect detection system comprises an imaging system for acquiring and displaying image information of a tunnel surface; a light supplementing device used for illuminating the surface of the tunnel and automatically balancing the brightness in the tunnel so as to ensure that the imaging system has sufficient brightness when acquiring image information; a signal processing system used for receiving and processing the image information of the tunnelsurface acquired by the imaging system and identifying the quality defect of the tunnel surface; and a central processing equipment used for controlling the signal processing system, the imaging system and the light supplementing device to work. According to the invention, the image information of the tunnel surface can be automatically collected and processed, the tunnel surface quality defect can be identified, and the tunnel can be supplemented with light in all directions, so that the collected image information is clearer, and the detection result is more accurate.

Description

technical field [0001] The invention relates to a tunnel surface quality defect detection system, which belongs to the field of tunnel engineering. Background technique [0002] In the field of tunnel engineering, the surface quality of the tunnel is directly related to the safety of running vehicles. [0003] Tunnel surface quality defect detection is mainly aimed at common tunnel surface diseases such as tunnel cracks, water leakage, and falling blocks. These diseases will bring great hidden dangers to the traffic safety of highways and railway tunnels. major traffic accidents. Therefore, the surface quality of the tunnel must be regularly tested in order to find potential safety hazards and repair them in time. [0004] Traditional tunnel surface quality defect detection often uses tools such as feeler gauges and ultrasonic instruments for manual detection, which is labor-intensive, low-efficiency, less auxiliary information, and has a high rate of false detection and m...
