Abstract
A method and apparatus for detecting a movement direction of a target object are provided. The method comprises: acquiring a video sequence of the target object, and determining positions of the target object in a plurality of image frames of the video sequence; setting a plurality of base vectors within a coverage range of an image collection apparatus capturing the video sequence, wherein an angle between each of the base vectors and a reference vector set according to a specific scene being captured satisfies a predetermined condition; for each of the base vectors, determining a movement direction of the target object between each pair of adjacent image frames with respect to the base vector, and determining a general movement direction of the target object with respect to the base vector thereby; determining a movement direction of the target object according to the general movement directions of the target object.
