Machine visual line scanning device and system and inspection vehicle

Abstract

The invention relates to the technical field of scanning detection, in particular to a machine visual line scanning device and system and an inspection vehicle. The machine visual line scanning devicecomprises an installing part, and a line scanning camera, a first light source and a second light source which are installed on the installing part. The installing part is used for fixedly installingthe machine visual line scanning device. The line scanning camera is installed on the installing part and used for collecting images of a tested object. The first light source and the second light source are arranged on the installing part and can rotate relative to the installing part so that the illumination ranges of the two light sources can at least be partly overlapped. At least part of theoverlapped area is located in the view range of the line scanning camera. By arranging the first light source and the second light source, by adjusting the relative angle of the two light sources, the illumination ranges of the two light sources are overlapped, and therefore speckles are eliminated, the scanning regional brightness is improved, the collected images are clearer, and the detectionreliability is improved.

Description

technical field [0001] The invention relates to the technical field of scanning detection, in particular to a machine vision line scanning device, system and inspection vehicle. Background technique [0002] During the long-term operation management and line maintenance of railway tracks, it is necessary to regularly detect or identify some defects and visible features on the track, including rail welds, cracks on the top surface of rails, skewed and missing fasteners, cracks on track plates, The separation gap of the mortar layer of the track slab, the invasion of foreign objects on the track, the cracks on the inner wall of the tunnel and water stains, etc. [0003] In the field of railway rail transit technology, machine vision line scanning technology has been developing faster and faster. Compared with traditional manual road inspection methods, machine vision line scanning technology is becoming more and more popular due to its fast, accurate and intelligent characteri...
