The invention discloses a train positioning method and speed detection method based on sleeper/fastener model identification, comprising the following steps: firstly, creating a full-field equipment positioning data graph, and then creating feature data of fasteners mounted on sleepers; and the whole-field equipment positioning data graph and the fastener feature data are bound to form a reference database, the reference database is imported into a vehicle-mounted computer of the train, and the vehicle-mounted computer receives sleeper photos shot by a high-speed camera of the train and carries out comparison calculation to obtain position information and speed information of the train. The structure is simple, a large number of sensors are not needed, and investment cost is reduced; the positioning and detection precision is high, the high-speed camera can provide enough photos, and the vehicle-mounted computer carries out data processing in real time.

    本发明公开了一种基于轨枕/扣件模型识别的列车定位方法及速度检测方法,首先创建全场设备定位数据图,然后创建安装在轨枕上的扣件特征数据,再将全场设备定位数据图和扣件特征数据进行绑定形成参考数据库并导入列车的车载计算机中,车载计算机接收列车高速相机拍摄的轨枕照片并进行对比计算,以得出列车的位置信息和速度信息。结构简单,不需要布置大量传感器,降低投资成本;定位及检测精度高,高速相机可以提供足够数量的照片,车载计算机实时进行数据处理。
