Embodiment Construction

[0039] A system for identifying holes in the waterproofing panels of laid sections of tunnels, such as figure 1 As shown, the system includes a car 101, on which a power supply module 102, a distance measuring module 103, an image acquisition module 104, an image processing module 105, a hole identification module 106, a hole marking module 107 and a car steering module 108 are integrated; wherein:

[0040] The trolley 101 can be adsorbed to the surface of the installed tunnel waterproof board, and move circularly, longitudinally or stop along the tunnel waterproof board;

[0041] The power supply module 102 is used to supply power to the trolley 101, distance measuring module 103, image acquisition module 104, image processing module 105, hole recognition module 106, hole marking module 107 and car steering module 108 in the system;

[0042] The distance measuring module 103 is used to record the number of wheel rotations of the trolley 101, and calculate the d...

Abstract

The invention discloses a system and a method for recognizing holes in the surface of a paved waterproof board of a tunnel. The method comprises the following steps of: acquiring data information in the surface of the paved waterproof board by using a digital imaging technology; accurately positioning holes in the surface of the waterproof board through a digital image processing and mode recognition technology; and marking at the same time. By utilizing the system and method provided by the invention, full automatic detection and recognition are realized, the holes in surface of the paved waterproof board are marked, thus the defects of heavy labor intensity, low safety, low work efficiency and accuracy of a recognized result in an artificial recognition method are overcome, the work efficiency is greatly improved at the same time, and the waterproof property of the waterproof board is greatly increased.

Description

[0001] technical field [0002] The invention relates to a detection device for a hole in a waterproof board, in particular to a system and method for identifying the hole in a waterproof board in a section of a tunnel that has been laid. Background technique [0003] Waterproofing of tunnel engineering has always been a technical problem. Water leakage is one of the common diseases of tunnels. The long-term effect of tunnel water leakage will greatly reduce the service life and functions of various facilities in the tunnel, and deteriorate the operating conditions of the tunnel. The current waterproof and drainage structures of tunnels in my country mostly adopt composite lining waterproof and drainage structures. Pouring the secondary lining structure. The waterproof board is sandwiched between the primary support and the secondary lining to form a composite lining structure. Among them, the waterproof board plays a very important role in the waterproofing of the st...
