The invention discloses a train positioning method, device and equipment in a subway tunnel and a storage medium, and the method comprises the steps: collecting environment data information in the subway tunnel, and obtaining a high-precision point cloud picture in the subway tunnel through calculation based on the environment data information; extracting target object features from the high-precision point cloud atlas to construct a structured point cloud atlas; acquiring target object features and first inertial navigation data acquired in real time when the train runs, matching the target object features acquired in real time with target object features in the structured point cloud atlas, and acquiring real-time position information of the train based on a matching result and the first inertial navigation data; and acquiring data information of the hectometer mark in the tunnel, which is acquired in real time when the train runs, and calibrating the real-time position information through calculation based on the data information of the hectometer mark to obtain the position information of the train. According to the technical scheme, the train positioning method is low in cost, high in precision and high in practicability.
