The invention provides a train positioning method and device, electronic equipment and a storage medium, and relates to the technical field of rail transit, and the method comprises the steps: obtaining a to-be-processed image, collected by image collection equipment on a train, of the same inner side surface of a tunnel in the train entering process, converting the to-be-processed image into a binary image, and storing the binary image in a storage medium; an advertisement screen is arranged on the same inner side surface of the tunnel; determining the current positioning detection state of the to-be-processed image based on the number ratio of the target pixel points to all the pixel points in the central vertical line direction in the binary image; when the current positioning detection state changes relative to the positioning detection state corresponding to the previous frame of image of the to-be-processed image, determining a target boundary of a target advertisement screen passed by the head of the train; and determining target positioning information of the train based on the advertisement screen position information, the size and the target boundary of the target advertisement screen. According to the technical scheme, the low-cost train pull-in positioning method is provided, and the equipment cost of train pull-in positioning can be reduced.

    本发明提供一种列车定位方法、装置、电子设备和存储介质,涉及轨道交通技术领域,该方法包括:在列车进站过程中获取列车上的图像采集设备采集的隧道同一内侧面的待处理图像,并将待处理图像转换为二值图像,隧道的该同一内侧面布设有广告屏;基于二值图像中中心垂线方向上目标像素点与所有像素点的数量占比确定待处理图像的当前定位检测状态;在当前定位检测状态相对于待处理图像的上一帧图像对应的定位检测状态发生变化时,确定列车的车头驶过的目标广告屏的目标边界;基于目标广告屏的广告屏位置信息、尺寸和目标边界,确定列车的目标定位信息。本发明的技术方案提供了一种低成本的列车进站定位方法,能够降低列车进站定位的设备成本。
