The invention discloses a rail vehicle wheel set tread 3D image detection method, which comprises the following steps: (1) when a train approaches an incoming line sensor, acquiring a train incoming line signal, and entering a train receiving state; the speed measurement radar obtains the real-time passing speed of the train, the train number recognition mechanism obtains the number of the passing train, and the positioning device obtains the position of each wheel and starts the corresponding tread image acquisition equipment to acquire a wheel tread image; acquiring and combining each wheel on a single side through a plurality of pairs of tread image acquisition devices so as to obtain a wheel tread image covering a complete tread, and matching the acquired wheel tread image information with a vehicle number; and (2) processing the acquired image to form a 2D image of the wheel tread and a 3D image of a corresponding area, and analyzing and calculating the 3D image data to obtain the rim thickness, the Qr value and tread wear information. According to the invention, through coordination work of multiple groups of tread image acquisition devices, non-stop on-line real-time detection of the full-circumference tread of the wheel is realized.

    本发明公开了一种轨道车辆轮对踏面3D图像检测方法,包括:(1)当列车车辆接近进线传感器,获得列车进线信号,进入接车状态;测速雷达获得列车实时过车速度,车号识别机构获得本次过车的车号,定位装置获得每个车轮的位置并启动对应踏面图像采集设备采集车轮踏面图像;单侧每个车轮经过多对踏面图像采集设备采集组合从而获得覆盖完整踏面的车轮踏面图像,并将采集的车轮踏面图像信息与车号的匹配;(2)通过对采集的图像处理,形成车轮踏面的2D图像和对应区域的3D图像,通过对3D图像数据的分析计算可以得到轮缘厚度、Qr值、踏面磨耗信息。本发明通过多组踏面图像采集设备协调工作实现车轮全周踏面不停车在线实时检测。
