The invention belongs to the field of rail vehicle attitude detection, and particularly relates to a rail vehicle running attitude detection method and system. According to the rail vehicle running posture detection method and system, the characteristic that the distance between linear laser spots of two parallel laser beams on a rail is not changed and the property of a similar triangle are utilized, the calibration process is converted into the mode that the distance between the two laser spots only needs to be measured and input into the system, and then the detection result can be obtained; the calibration-free effect is achieved, the problem that due to the fact that an existing detection method is large in calibration difficulty, large-scale application cannot be achieved is solved, and real-time monitoring of the whole-process running posture of the railway vehicle is achieved.

    本发明属于轨道车辆姿态检测领域,尤其涉及一种轨道车辆运行姿态检测方法及检测系统。本发明的轨道车辆运行姿态检测方法及检测系统,利用两条平行激光束在轨道上的线形激光斑之间距离不变的特点和相似三角形的性质,把标定的过程转换为只需要测量两道激光斑间的距离并输入系统就可以得到检测结果,达到了免标定的效果,解决了现有检测方法由于标定难度大,无法大规模应用的问题,实现了对轨道车辆全过程运行姿态的实时监测。
