The invention relates to the technical field of wheel set measurement, in particular to a train wheel set size online image acquisition method. The method comprises the following steps: step 1, measuring train type speed of a system by a magnetic steel array; 2, according to the train speed, the collection interval time Tj is calculated; 3, the image acquisition device performs data sampling according to the interval time; and 4, the image acquisition system fuses the data in one acquisition period into a group of wheel set data. By means of the method, the running speed of the train can be measured under the low-speed condition, and the image speed can be collected under the low-speed condition of the train.

    本发明涉及轮对的测量技术领域,具体涉及一种列车轮对尺寸在线图像采集方法。本发明的方法包括步骤一、磁钢阵列测量系统列车形式速度;步骤二、根据列车速度,计算采集间隔时间Tj;步骤三、图像采集装置按照间隔时间进行数据采样,步骤四、图像采集系统将一个采集周期内的数据融合为一组轮对数据。本发明的方法可以在低速的情况下测量列车的运行速度,在列车较低速度下的图像速度的采集。
