Aiming at the need to measure the full profile of wheelsets in the maintenance workshop,this paper integrates factors such as environment,working conditions,cost,and demand,and adds a wheelset profile acquisition device for laser sensing method to the existing wheel lathe measurement equipment.Considering the problem that the profile collection position does not exceed the axis during measurement by the wheelset measuring machine due to the different lifting heights of the wheelset axle,which will cause errors to the profile measurement data,this paper proposes an image-based wheelset profile acquisition device.Adaptive centering method for the algorithm reflects the robustness to changes in the surface texture of the object and greatly increases the accuracy of the detection of small targets such as lasers.The average detection time for each piece is 1.01 s,meeting the real-time requirements,which realizes fast and accurate adaptive adjustment of the profile collection device under the influence of different lighting conditions,improves the accuracy of profile detection and provides a foundation for the layout of wheelset turning plans.
