摘　　要：提出一种基于结构光视觉传感技术的轮对踏面擦伤检测新方法。通过结构光扫描轮对踏面,在踏面上产生相应的变形光,利用视觉传感技术提取结构光变形曲线,通过滤波、二值化、分割、差影等图像处理方法获得踏面一个扫描行的数据。轮对旋转一周,结构光视觉传感器采集轮对一周整个踏面视觉信息,通过对数据矩阵进行处理,得到了轮对踏面擦伤结果。A new method for inspecting scuffed wheel tread was introduced.This method makes use of constructional ray vision sensibility technology.Scanning a wheel tread by constructional ray,the ray of deformation on the tread will be produced.The ray of deformation is then treated to generate a line of scanned data for the tread.Having turn the wheel set a complete revolution,the constructional ray vision sensor obtains vision information on all points of the circumference of the wheel tread,and so,through processing the information above,the scuff condition on wheel tread can be found.
