Train part information collector

The utility model relates to a train component information collector comprising a supporting frame, a line scan camera arranged on the supporting frame, a laser and an area-array camera, wherein the line scan camera and the laser are parallel, the area array camera is located on the lateral side of the line scan camera, and the beam projecting range of the laser is located within the shooting range of the line scan camera and the area array camera. According to the train component information collector, the electronic components of the laser, the line scan camera and the area array camera are combined, automatic monitoring of component abnormality is achieved in an electronic mode, namely, human power is replaced by machine vision, and meanwhile brightness and depth information of detected components and detected positions is acquired, and the train component information collector is used as powerful complementing for single image component abnormality recognition and provides rich and objective data foundations for recognition of component abnormality.
