Abstract

A three-dimensional space-based gear shifting position recognition method, system, and medium are disclosed, comprising: real-time acquisition of the spatial position coordinates of a gear shift lever, the spatial position coordinates including lateral coordinate components, longitudinal coordinate components, and depth coordinate components; calculation of at least a weighted spatial distance between the spatial position coordinates and a preset reference coordinate for a certain gear; wherein the depth dimension weighting coefficient is greater than the lateral dimension weighting coefficient and the longitudinal dimension weighting coefficient; comparison of the weighted spatial distance with a preset gear engagement recognition threshold for the corresponding gear; and determination that the gear shift lever is engaged when the weighted spatial distance is less than the gear engagement recognition threshold. This invention, by introducing three-dimensional spatial coordinate detection (lateral, longitudinal, and depth components), overcomes the limitations of traditional two-dimensional planar projection, significantly improving the recognition accuracy and operational reliability under high-density gear layouts.
