Embodiment Construction

[0029] In order to make the purpose, technical solution and advantages of the present application clearer, the implementation manners of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0030] The "plurality" mentioned herein means two or more. "And / or" describes the association relationship of associated objects, indicating that there may be three types of relationships, for example, A and / or B may indicate: A exists alone, A and B exist simultaneously, and B exists independently. The character " / " generally indicates that the contextual objects are an "or" relationship.

[0031] In related technologies, two methods are usually used to determine the running direction of the subway. One is to determine the running direction of the subway through the direction of instantaneous acceleration: when the user takes the subway, the acceleration sensor in the terminal can record the instantaneous acceleration, and the i...

Abstract

The embodiment of the invention discloses a subway running direction determination method and device, a terminal and a storage medium, and belongs to the field of artificial intelligence. The method comprises the steps that in the subway acceleration stage, acquiring first acceleration data collected by a linear acceleration sensor wherein the first acceleration data comprise acceleration data inall directions under a terminal coordinate system; converting the first acceleration data into second acceleration data, wherein the second acceleration data comprises acceleration data in each direction under a world coordinate system; and determining the subway running direction according to the second acceleration data in the target duration. By converting the first acceleration data collectedby the terminal into the second acceleration data, the influence of the terminal posture on the acquired acceleration direction is avoided, and by comprehensively analyzing the second acceleration data within the target duration, the problem that the subway running direction is determined inaccurately due to the fact that the single acceleration direction is unstable can be avoided.

Description

technical field [0001] The embodiments of the present application relate to the field of artificial intelligence, and in particular to a method, device, terminal and storage medium for determining a subway running direction. Background technique [0002] As a daily means of transportation, the subway can bring convenient and rapid rail transit services to people. [0003] Since the operation of the subway is directional, when taking the subway, people need to choose to take the subway in the corresponding running direction according to the destination station and the current station. However, at present, the running direction of the subway needs to be judged by humans. Correspondingly, when the running direction of the subway is wrong, the passengers need to perceive it independently and then transfer. Contents of the invention [0004] Embodiments of the present application provide a method, device, terminal, and storage medium for determining a running direction of a su...
