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 present application discloses a method, device, terminal and storage medium for determining the running direction of a subway, belonging to the field of artificial intelligence. The method includes: during the acceleration phase of the subway, acquiring first acceleration data collected by a linear acceleration sensor, the first acceleration data including acceleration data in various directions under the terminal coordinate system; converting the first acceleration data into second acceleration data, The second acceleration data includes acceleration data in various directions in the world coordinate system; according to the second acceleration data within the target duration, the running direction of the subway is determined. By converting the first acceleration data collected by the terminal into the second acceleration data, the influence of the terminal attitude on the acquired acceleration direction is avoided. By comprehensively analyzing the second acceleration data within the target duration, the instability of a single acceleration direction can be avoided. This caused an inaccurate determination of the direction of subway travel.

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...
