摘　　要：内距尺是保证铁路机车行车安全的重要量具,由于其体积较大,受人眼视觉疲劳、视角等因素的影响产生误差较大,为提高轮对距检测精度,保证机车运行安全,本文提出了运用机器视觉技术进行内距尺刻度的识别。实验证明:该方法能有效避免人为因素的读数误差,提高了铁路检测的效率。Internal distance scale is an important measuring tool to ensure the safety of railway locomotive running.Due to its large size,it has a large error due to the influence of human eye visual fatigue,Angle of view and other factors.In order to improve the detection accuracy of wheelset distance and ensure the safety of locomotive running,machine vision technology is proposed to identify the scale of internal distance scale.Experimental results show that this method can effectively avoid the reading error of human factors and improve the efficiency of railway detection.
