成果介绍

本发明公开了一种非接触的钢轨表面伤损检测方法及其装置，钢轨表面伤损检测方法包括：由里程计测量载体平台的里程数据，同时由GPS接收机测量载体平台的位置数据；同步控制电路根据里程数据和位置数据对IMU和线激光扫描仪进行同步控制，并输出同步信息给计算机；IMU测量载体平台的姿态参数，线激光扫描仪获取钢轨表面数据并传输给计算机；计算机根据里程数据、位置数据、姿态参数和钢轨表面数据计算出钢轨表面三维点云；根据钢轨表面数据定位伤损区域并进行特征提取，结合钢轨表面三维点云判定伤损信息；利用激光扫描获取钢轨表面轮廓信息，避免钢轨表面伤损对超声波或电磁信号回波的干扰，通过钢轨表面三维点云提高了伤损判断的准确性。
