Expressway tunnel detection vehicle system based on machine vision

Abstract

The invention provides an expressway tunnel detection vehicle system based on machine vision. The expressway tunnel detection vehicle system comprises a data collection system, a data processing and analysis system and a WEB display system. The data collection system comprises a detection vehicle body, a power supply system, a control system, an environment detection system, an image collection system and a laser scanning system. The power supply is equipped with a generator and an uninterrupted power source UPS. The control system employs an industrial control computer for control. The environment detection system employs a carbon monoxide detector and an anemograph. The expressway tunnel detection vehicle system is characterized in that the image collection system comprises a light source, a first image capturing device, a second image capturing device, a mileage positioned, an illumination detection device and a metal ball installed at the vehicle top; the first image capturing device captures tunnel lining apparent disease images; the second image capturing device captures tunnel whole course illumination images; the laser scanning system is an outline scanning device of a tunnel. The expressway tunnel detection vehicle system obtains tunnel diseases and driving environment data through continuous scanning of tunnel surfaces.

Description

technical field [0001] The present invention relates to an expressway tunnel detection system, in particular discloses a machine vision-based expressway tunnel detection vehicle system, which is a vehicle-mounted automatic detection technology, and adopts a combination of image processing and laser scanning to detect tunnel defects Compared with environmental health monitoring, the detection speed is faster, the accuracy is higher, and the cost of tunnel disease detection is greatly reduced. Background technique [0002] At present, my country has shifted from the large-scale construction of expressways to the stage of expressway use and management. With the rapid increase in the operating mileage of expressways, the structural maintenance of expressways will become increasingly heavy. In order to ensure the smooth flow of expressways and better serve the economy For construction services, it is required to shorten the maintenance operation time as much as possible, and the t...

AI Technical Summary

Problems solved by technology

At present, most of the highway tunnel diseases are still inspected manually, which not only has low efficiency and poor accuracy, but also seriously affects the normal traffic of the highway.

Traditional maintenance and inspection methods can no longer meet the current operating conditions of expressways. It is necessary to design an advanced maintenance machinery and construction method to shorten the time occupied by lanes for maintenance construction operations, reduce traffic congestion, and implement rapid maintenance to the greatest extent.
