Title:
METHOD AND APPARATUS FOR DETERMINING RUNNING DIRECTION OF METRO TRAIN, AND TERMINAL AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2021/115268
Kind Code:
A1
Abstract:
Disclosed are a method and apparatus for determining a running direction of a metro train, and a terminal and a storage medium, wherein same belong to the field of artificial intelligence. The method comprises: at a metro train acceleration stage, acquiring first acceleration data collected by a linear acceleration sensor, wherein the first acceleration data comprises acceleration data of all directions under a terminal coordinate system; converting the first acceleration data into second acceleration data, wherein the second acceleration data comprises acceleration data of all directions under a world coordinate system; and determining the running direction of a metro train according to the second acceleration data within a target time range. The first acceleration data collected by the terminal is converted into second acceleration data, such that the attitude of the terminal is prevented from affecting the acquisition of an acceleration direction; and the second acceleration data within the target time range is comprehensively analyzed, such that the problem of the determined running direction of a metro train being inaccurate caused due to the instability of a single acceleration direction can be avoided.
