The invention discloses an on-line wheel tread image detection device for real-time recording of wheel tread conditions; as a wheel rotates, images of wheel tread during one circle of rotation can be taken, so that viewing and subsequent image processing can be facilitated; and during the subsequent image processing, all single images taken by a camera are automatically spliced into a complete image by an image automatic splicing technology. An image detection module can automatically locate and automatically recover the image detection device through an automatic push device. Two light sources are arranged, when a front light source and a side light source act on the wheel tread, uniform illumination is generated, and influence caused by uneven illumination due to an irregular shape of the wheel tread can be overcome. The camera is laid out as follows: the camera is located in the center of the front light source, so that distortion of the taken images is smallest, and the subsequent image processing can be facilitated. The invention also discloses a flaw detection system and a train using the on-line wheel tread image detection device.
Description
technical field [0001] The invention relates to the technical field of railway detection, in particular to a train, an online wheel tread image detection device and a flaw detection system. Background technique [0002] In the maintenance process of railways, the detection of train wheels is an important part. [0003] At present, when inspecting the tread of a wheel, the images of the tread of the wheel are usually taken manually by a camera, and the obtained images are separated images one by one, which is inconvenient for viewing and subsequent image processing. [0004] Therefore, in view of the above situation, how to detect the wheel tread image for easy viewing and subsequent image processing has become an important technical problem to be solved urgently by those skilled in the art. Contents of the invention [0005] In view of this, the present invention provides an online wheel tread image detection device, which is used for real-time recording of the wheel trea...
