The invention relates to a tread defect information detection system and method. The system comprises a three-dimensional information acquisition module, an image processing module and a tread defect detection module, wherein the three-dimensional information acquisition module is used for acquiring a plurality of pieces of first image information comprising the tread two-dimensional image information of an identical position of a train wheel from at least two imaging positions; the image processing module is used for processing the first image information acquired by the three-dimensional information acquisition module respectively to obtain a plurality of pieces of curved surface image information of the tread of the train wheel; the tread defect detection module is used for constructing the spatial curved surface information of the tread of the train wheel according to the curved surface image information, and comparing the constructed spatial curved surface information with preset tread curved surface information to obtain the defect information of the tread of the train wheel. By adopting the system, a plurality of images of the tread can be acquired simultaneously according to at least two imaging positions to obtain a spatial curved surface comprising the tread three-dimensional information, so that the tread detection accuracy is increased during tread defect detection with the spatial curved surface.
