Tunnel detection device based on digital panoramic photography and detection method thereof

Abstract

The invention belongs to the technical field of tunnel quality detection and discloses a tunnel detection device based on digital panoramic photography and a detection method thereof. The tunnel detection device based on digital panoramic photography comprises a detection vehicle which runs along the central line of a tunnel, a cone reflector fixed at the center of the front end face of a vehicle head of the detection vehicle, a magnetic compass fixed at the center of the cone reflector, a CCD (charge coupled device) camera fixed at the vehicle head of the detection vehicle, an incremental rotary encoder fixed on a rotating shaft of a rear wheel of the detection vehicle in the sleeving manner and a pulse counter arranged on the detection vehicle, wherein the conical surface of the cone reflector faces the forward direction of the detection vehicle; the CCD camera is positioned in front of the center of the cone reflector; a lens of the CCD camera horizontally faces the cone reflector; the input end of the pulse counter is electrically connected with the incremental rotary encoder; the output end of the pulse counter is electrically connected with the control end of the CCD camera; the CCD camera is electrically connected with an industrial control computer.

Description

technical field [0001] The invention belongs to the technical field of tunnel quality detection, and in particular relates to a digital panoramic camera-based tunnel detection device and a detection method thereof. Background technique [0002] With the rapid development of the economy, the construction of highway tunnels in our country is increasingly favored by people. With the increasing number of tunnels, the construction technology of highway tunnels in our country has also been greatly developed. However, after a long period of tunnel operation, tunnel leakage, lining cracking, lining deformation, and uneven quality of the road surface usually occur, which affect the safety of vehicles passing through the tunnel. In order to ensure the safety of driving, it is necessary to regularly detect the comprehensive condition of the tunnel. [0003] In the past, in the process of comprehensive inspection of tunnel quality, for problems such as tunnel leakage, lining cracking ...
