Problems solved by technology

In the field of transportation, machine vision has been widely used in the rapid detection of road pavement and railway tunnels, but less in road tunnels. The fundamental reason is that compared with road pavement and railway tunnels, road tunnels have different cross-sectional dimensions, Tunnel lighting is complex, and the detection process is greatly affected by traffic flow, driving trajectory, and road bumps, which also increases the research difficulty of machine vision technology in the rapid detection of road tunnels

Embodiment 1

[0036]figure 1 It is a schematic structural diagram of a tunnel intelligent detection vehicle provided in Embodiment 1 of the present invention. Such as figure 1 As shown, the tunnel intelligent inspection vehicle includes a fixed bearing system 1, a visual acquisition system 2, a vehicle speed measurement system 3, a safety warning system 4, and an electrical control system installed inside the vehicle body. The above hardware is integrated on a vehicle chassis to form a An intelligent tunnel detection system. The tunnel intelligent inspection vehicle provided in this embodiment is based on machine vision and robot technology. Sensors such as digital cameras, laser three-dimensional scanners, and encoders are integrated on the inspection vehicle, and it is equipped with related mechanical and electrical devices. Under this condition, the information of the vehicle and the tunnel lining surface is collected in real time. The technical solution provided in this embodiment rea...

Embodiment 2

[0046] This embodiment provides a detection method for a tunnel intelligent detection vehicle, and the tunnel intelligent detection vehicle is the tunnel intelligent detection vehicle provided in Embodiment 1. For the tunnel intelligent detection vehicle, refer to the specific description of Embodiment 1, and details will not be repeated here.

[0047] see Figure 1-5 In this embodiment, before starting the detection, power is supplied to each electrical component of the tunnel intelligent detection vehicle, and the visual acquisition system 2, the vehicle speed measurement system 3 and the safety warning system 4 are in working state through the electrical control system. First, carry out data acquisition work on the left tunnel: before the inspection vehicle enters the tunnel, rotate the mounting bracket 2-1 to the left working position through the rotary drive 2-5, and open the door of the sliding compartment 1-3 and the data acquisition software. When the detection vehicl...

Description

technical field [0001] The invention relates to the technical field of traffic engineering, in particular to a tunnel intelligent detection vehicle and a detection method thereof. Background technique [0002] At present, the detection of highway tunnels needs to be completely or partially closed to traffic. Manual or artificial instruments are used to detect tunnels with the help of climbing vehicles. This detection method has low work efficiency, high risk, and high missed detection rate, and it is difficult to count and analyze the development of diseases. The trend, and more importantly, the informatization management of detection data cannot be realized, which hinders the transformation of highway maintenance to intelligence and informatization. The newly promulgated "Technical Specifications for Highway Tunnel Maintenance" (JTG_H12-2015) in 2015 added new items for frequent inspection of tunnels, and the frequency of inspections has also increased significantly, and en...
