The invention provides a railway freight car speed measuring method, a railway freight car speed measuring system, a railway freight car speed measuring device and computer equipment, and the method comprises the steps: responding to a magnetic steel trigger signal, and controlling a dual-laser transmitter to transmit a laser signal; receiving the laser signal based on double laser receivers, and converting the laser signal into a receiving signal; the double-laser transmitter and the double-laser receiver are arranged on the two sides of a railway track. Calculating the speed of the train based on the received signal; and segmenting the train scanning image based on the receiving signal and the speed to obtain an image of each carriage. According to the method provided by the invention, the accuracy of speed measurement of the railway freight train can be improved so as to meet the requirement of carriage linear array scanning image cutting.

    本发明提供了一种铁路货检测速方法、测速系统、装置及计算机设备,所述方法包括响应磁钢触发信号,控制双激光发射器发出激光信号;基于双激光接收器接收所述激光信号,将所述激光信号转换为接收信号;所述双激光发射器与所述双激光接收器设置于铁路轨道两侧;基于所述接收信号计算列车的速度;基于所述接收信号和所述速度对列车扫描图像进行分割,得到各节车厢图像。本发明提供的方法能够提高铁路货运列车测速的准确性,以满足车厢线阵扫描图像切割的需要。
