Embodiment 1

[0097] refer to Figure 1-11 , a tunnel full-section high-speed dynamic health detection device based on active panoramic vision, including: tunnel inspection vehicle, active panoramic vision sensor, RFID reader, wireless receiving and sending unit, controller, station-level communication system or central monitoring Central server: the central monitoring center server constitutes a full-tunnel safety inspection network through the station-level communication system, and the station-level communication system receives information sent from the wireless receiving and sending unit configured on the tunnel inspection vehicle. The panoramic image of the tunnel cross section, and the panoramic image of the tunnel cross section is transmitted to the central monitoring center server through the full tunnel safety detection network in time;

[0098] The tunnel inspection vehicle is equipped with an active panoramic vision sensor, an RFID reader, a distance measuring wheel, a wireless ...

Embodiment 2

[0233] In this embodiment, the rest of the implementations are similar, the difference is that the storage capacity is increased on the controller on the tunnel inspection vehicle, and when the tunnel inspection vehicle is finished, the panoramic image of the inner wall of the tunnel is sent to the The central monitoring center server.

Embodiment 3

[0235] In this embodiment, other implementations are similar, except that the position of the active panoramic vision sensor is installed on the tunnel inspection vehicle, and the active panoramic vision sensor is arranged at the rear of the tunnel inspection vehicle.

Abstract

A tunnel disease full-section dynamic rapid detection device based on active panoramic vision comprises a tunnel detection vehicle, an active panoramic vision sensor, an RFID (radio frequency identification) reader, a wireless receiving-transmitting unit, a controller, and a station-level communication system or a central monitor center server; the central monitor center server comprises a full-directional vision sensor calibrating module, an active panoramic vision sensor calibrating database, a Zi-th distance tunnel section panoramic image data reading unit, a full tunnel section panoramic image base, a full-directional plane laser information analysis and point cloud data acquisition unit, a tunnel section panoramic image expansion and splitting unit, a tunnel suspected disease image pretreatment unit, a tunnel suspected disease image treatment unit, a tunnel disease image characteristic index extracting unit, and a tunnel safety status estimating unit. The invention provides a novel tunnel full-section high-speed dynamic health examination method, automatically detecting, judging and estimating various defects present in a tunnel to provide effective technical support for tunnel maintenance and completion acceptance inspection.

Description

technical field [0001] The invention relates to the application of panoramic laser light source, omni-directional vision sensor, digital image processing and computer vision technology in the detection of tunnel damage, in particular to a full-section dynamic rapid detection device for tunnel damage based on active panoramic vision. Background technique [0002] my country is the country with the longest operating mileage of railway tunnels in the world. Relevant investigations and studies have shown that a considerable number of tunnels have disease problems, which seriously affect the safety of my country's railways. [0003] At this stage, the traditional methods most used in the tunnel disease detection process mainly include visual inspection, drilling coring, water pressure testing and drilling sound waves. The non-destructive testing methods for tunnel lining and pavement mainly include ground radar method, rebound method, ultrasonic / sonic method, laser scanning metho...
