摘要

提出一套基于双目视觉系统的轮对踏面自动检测及等效锥度计算系统。系统采用激光光源，通过CCD相机获取镟修轮对的踏面图像，对图像采用灰度化、滤波、边缘检测、分割、膨胀、腐蚀等处理方法，获取踏面轮廓参数，采用Simpack与Microsoft Visual Studio软件相结合，改进并简化UIC 519计算方法，实现轮对的等效锥度计算。该系统提高了车辆轮对等效锥度的计算效率与精度，有助于优化镟修轮对检测流程，保障车辆运行安全。

Abstract

A system of automatic wheelset tread detection and equivalent conicity calculation based on binocular vision system was proposed, which used laser light source to obtain the tread image of the repaired wheel with the CCD camera. The method of gray processing, filter, edge detection, image segmentation, expansion and erosion was used to obtain the parameter of the wheel. With improving and simplifying the method of equivalent conicity calculation in the UIC 519 standard, the equivalent conicity calculation of the wheelset was realized by combining Simpack with Microsoft Visual Studio software. This system improved the calculation efficiency and accuracy of wheelset equivalent conicity, it helps to optimize the inspection process of the wheelset and ensure the saft of vehicle operation.
