The invention provides a train wheel set size detection method and a corresponding train wheel set size detection device, and the measurement precision and robustness are effectively improved. The invention discloses a method for detecting the size of a train wheel set. The method comprises the following steps of: 1, detecting the arrival of a wheel by using a wheel detection module arranged at the front part; 2, controlling a vision measurement module to project laser by using an electrical control module, continuously collecting multiple frames by using a camera, and acquiring multiple frames of laser light bar wheel images corresponding to each wheel by using a data processing module; step 3, inputting multiple frames of images acquired by each wheel into the trained laser light bar wheel image quality evaluation CNN network for reasoning calculation to obtain a quality evaluation result of each frame of image of the wheel; and step 4, selecting an image of which the quality meets the requirement for each wheel, calculating wheel set geometric dimension parameters according to the visual model, and taking the wheel set geometric dimension parameters as a final result.
