Abstract

The embodiment of the invention provides a locomotive wheel diameter detection method. The locomotive wheel diameter detection method comprises the following steps: projecting a first ray of light to a locomotive wheel tread to form a light-sectioning curve; acquiring a light-sectioning image comprising the light-sectioning curve; utilizing an image segmentation method to analyze the obtained light-sectioning curve image, so as to obtain the locomotive wheel diameter.

Description

technical field [0001] The invention relates to the field of mechanical detection, in particular to a method for detecting the diameter of a locomotive wheel. Background technique [0002] The wheel is one of the key components of the locomotive running system. The wheel is the part on the locomotive wheel that is in contact with the rail. Its main function is to ensure the running and steering of the locomotive wheel on the rail. During the locomotive running, the working status of the locomotive wheels will directly affect the safety of the locomotive. Therefore, the wheels are often used as one of the important parts of the daily maintenance of the locomotive. [0003] The daily maintenance of locomotive wheels mainly includes the inspection of locomotive wheel dimensions and defect detection of locomotive wheels, among which, the inspection of locomotive wheel dimensions includes the detection of locomotive wheel diameters, the measurement of locomotive rim thickness and...
