The invention relates to a visual positioning device, method and equipment for a train in a tunnel and a medium. The device comprises a vehicle-mounted controller, a vehicle-mounted visual odometer, a train surface identification code, a trackside visual beacon, a trackside visual counter axle and feature points arranged in the tunnel according to a set distance. The vehicle-mounted visual odometer collects trackside visual beacons and feature points, and the trackside visual odometer collects train surface identification codes; the vehicle-mounted controller obtains the current speed and the relative displacement from the vehicle-mounted visual odometer, calculates the current position in the line according to the trackside visual beacon and conducts calibration and positioning, and meanwhile obtains the current position in the line from the trackside visual odometer and conducts calibration and positioning, so that continuous speed measurement and positioning of the train are achieved. Compared with the prior art, the method has the advantages that the redundancy and availability of the positioning system are enhanced, the cost is lower and the like.

    本发明涉及一种隧道内列车视觉定位装置、方法、设备及介质,该装置包括车载控制器、车载视觉里程计、列车表面标识码、轨旁视觉信标、轨旁视觉计轴和隧道内部按设定距离布置的特征点;所述车载视觉里程计采集轨旁视觉信标和特征点,所述轨旁视觉计轴采集列车表面标识码;所述车载控制器从车载视觉里程计获取的当前速度和相对位移,根据轨旁视觉信标计算当前在线路中的位置并进行校准定位,同时从轨旁视觉计轴获得当前在线路中的位置并进行校准定位,从而实现列车连续测速和定位。与现有技术相比,本发明具有增强了定位系统的冗余度和可用性、成本更低等优点。
