An information fusion technology based train wheel set tread damage online detection and recognition method comprises the steps of 1 image acquisition, 2 image pre-processing, 3 preliminary damage detection, 4 accurate damage positioning and 5 damage judgment, wherein the step 4 is that an infrared image processing result and a gray image processing result are subjected to data fusion, a tread image is marked and positioned, damaged texture and area are obtained through morphological processing, morphological processing is conducted on tread cracks to obtain the length of the cracks, and the step 5 is that features of a tread damage region are extracted and selected, a BP neural network is designed and trained, the defects of the BP neural network are classified, and reference is provided for operation situation analysis of wheels, locomotives and lines according to train wheel set tread damage information recorded by a terminal processing unit. The information fusion technology based train wheel set tread damage online detection and recognition method has the advantages of being comprehensive in detection, high in automatic degree, high in detection speed and detection accuracy and the like.
