Description
Technical Field
The patent relates to an information intelligent detection experimental device for tunnel lining diseases, in particular to an intelligent detection simulation experimental device for tunnel lining diseases based on image recognition, which is used for developing, improving and effect testing a machine vision detection system for tunnel lining diseases.
Background
In recent years, the construction and research of tunnel engineering such as roads, railways, urban rail transit and the like in China have been rapidly developed, and the development and application of an informatization, scientific and convenient maintenance and detection system of tunnels have been gradually emphasized for many years.
Common tunnel defects include the following: water leakage of the tunnel, corrosion of the lining, cracking damage of the lining, frost damage of the tunnel, damage of the tunnel portal, cracking damage of the whole ballast bed, damage of accessory structures and the like. According to a plurality of tunnel disease experiences, lining structure breakage and water leakage are main factors influencing tunnel safety (the Chinese highway journal of 2015 5 month, 5 th, 28 th volume, the research review of Chinese tunnel engineering 2015).
The digital photography-based measuring method can be divided into two categories of deformation measurement and feature identification. The digital photography deformation measurement mainly takes displacement observation as a target, displacement is calculated according to the coordinate change of a target image measuring point, then strain calculation is carried out, and the deformation characteristic of the target is analyzed on the basis; the digital photographic feature recognition mainly aims at separating feature objects, and is to separate features interested by research or technical personnel from images, such as crack image detection of a circuit board, automatic identification of a license plate number in a road traffic system, structural composition of rock-soil materials, identification of cracks of concrete materials and the like (the digital photographic measuring method and application of rock-soil deformation, the book of Li Yuan province).
The items of tunnel detection generally include tunnel convergence value, vault subsidence value, surface subsidence value, and other diseases such as: and (5) detecting lining cracks and water leakage conditions. Wherein, the deformation detection (convergence value and settlement value) and the disease detection are the more important of the detection, the former belongs to the category of 'deformation measurement', and the latter belongs to the category of 'feature recognition'. The digital photogrammetry method related by the invention is 'feature recognition'.
The traditional tunnel engineering detection means mainly include contact measurement and total station non-contact measurement. The convergence value is mainly measured by using a convergence meter, and the settlement value is measured by using a level gauge, a steel ruler and the like. The total station non-contact measurement method has certain reliability as a mature technology, but has the following defects: the measurement precision is not as good as that of the traditional measurement means, and the accuracy of the data is also influenced by the operation of operators, so that manual errors exist, the errors of the instruments and errors caused by other influences of the field environment.
In recent years, non-contact measurement methods based on digital image measurement technology have been developed rapidly. For example, the development and application of the informatization and intelligent detection technology of tunnel lining diseases at home and abroad and the advantages and disadvantages of various technologies are comprehensively introduced and compared in the current situation and analysis and comparison of tunnel disease rapid detection technology in the 3 rd stage of 2016 (road and vehicle transport).
At present, intelligent information detection of various tunnel lining diseases is generally completed by an intelligent system based on image recognition, and comprises the following steps: the device comprises an image acquisition device, a fixing and moving device of the image acquisition device, an information transfer device and a rear-end information collection and processing system. The system has a rudiment scheme applied to engineering, and scientific research institutions such as universities and enterprises optimize and improve the system. For example, in volume 45 of 2018, volume 3 of a shield tunnel lining disease identification method based on deep learning, a rapid mobile tunnel scanning detection system is described, which can move in a tunnel, acquire an image of a lining surface and transmit the image to a rear computer for processing. A novel shield tunnel water leakage disease image recognition algorithm based on a full convolution network is provided in the sentence of the book 36, volume 12, 12 th, of the report on rock mechanics and engineering, 2017. The article entitled "research on model test of influence factors of definition of image of tunnel lining", which is added in volume 36 of journal of rock mechanics and engineering, 2017, describes a simple simulation experiment device for acquiring images of tunnel lining surfaces based on computer vision in a laboratory. The device pastes the information paper printed with the characteristic image on the bent thin wood board and fixes the bent thin wood board on an experimental wall, places equipment such as a camera, a light source, an industrial computer and the like on a movable trolley, and utilizes the movement of the trolley to construct the relative movement of the camera and the observed image.
The development and application of the technology in universities and enterprises are verified by verifying the effectiveness of the manufactured system through field actual application or manufacturing a physical model. Although the two modes are closest to the practical application environment, scientific research personnel are required to transport all manufactured equipment to a tunnel engineering site, manpower and material resources are consumed, time is wasted, the tunnel site environment is complex and severe, environment variables are difficult to control one by one, and specific reasons are difficult to judge if an experimental result does not reach an expected target, so that the laboratory research device for the tunnel disease image recognition system is provided. The method aims to create an experimental environment similar to the field environmental condition for researchers in a laboratory, and facilitates the research of the researchers in developing, improving and researching the digital image measuring system in the laboratory.
