The image acquisition system for train parts provided by the present invention includes: a line array camera and an area array camera arranged between two branch rails of a track and / or outside the branch rails for image acquisition of train parts; The first supplementary light source and the second supplementary light source that are connected to the line array camera and the area array camera to supplement light for the two respectively; The first controller for establishing a corresponding relationship between the number of images; the projection direction of the first supplementary light source is the same as the shooting direction of the lens of the line array camera, and the projection direction of the second supplementary light source is the same as the shooting direction of the lens of the area array camera. The above-mentioned system combines the advantages of line array cameras and area array cameras, and adopts images with better effects, which can observe key and small components from multiple angles, reduce detection dead angles, expand detection range, and improve the accuracy of abnormal detection of train parts. The invention also provides a system for detecting abnormality of train components.
Description
technical field [0001] The invention relates to the technical field of train image acquisition, in particular to an image acquisition system for train parts, and also relates to an abnormality detection system for train parts with the above-mentioned image acquisition system for train parts. Background technique [0002] Railway transportation occupies a relatively important position in the field of transportation due to its advantages of large transportation volume, fast speed, high safety and reliability. [0003] As the core part of railway transportation, trains may experience abnormalities in car body parts during operation. This seriously threatens the safe running of the train. Therefore, it is very important to detect the abnormality of train parts to ensure the safe operation of trains. [0004] At present, image acquisition is usually used to detect the abnormality of parts by analyzing the images of train parts. In the above detection process, images are usuall...
