Abstract

The invention provides a slit detection device and a detection method. The slit detection device comprises a positioning template, an image acquisition device and an image processing device. The positioning template comprises multiple marking points, and is arranged on a to-be-measured slit part and used for positioning a to-be-measured slit position. The image acquisition device is arranged on the side face of the slit position and used for acquiring an image of a region where the positioning template is arranged. The image processing device is used for receiving the image acquired by the image acquisition device, processing the image, determining the image of the region where the positioning template is arranged, and calculating the slit distance in the template position according to the image of the region where the positioning template is arranged. The slit detection device and the detection method are suitable for field installation and maintenance and the slit distance can be monitored in real time.

Description

technical field [0001] The invention relates to the field of intelligent detection, in particular to a gap detection device and a detection method. Background technique [0002] During the construction of the railway track, gaps are prone to appear in the mortar layer between the railway track slab and the subgrade slab. It is necessary to accurately locate and measure the gap for real-time monitoring to ensure the safety and reliability of the railway track. [0003] The existing common gap detection methods are divided into contact type and non-contact type. The contact type is suitable for active measurement occasions with high precision requirements, and the non-contact type mainly uses photosensitive devices or images for measurement. For example, the patent with the publication number CN101915551A: "A Pipe Gap Detection Tool" discloses a method for detecting gaps using photosensitive devices, and the patent with the publication number CN105651194A: "A Non-contact On-li...
