Abstract: A throwing position acquisition method and apparatus, a computer device, and a storage medium. The method includes: acquiring image frames of a target video; acquiring a projectile position in each image frame; acquiring a trajectory starting point position of the target object based on the projectile position in each image frame; acquiring, based on projectile positions corresponding to at least one group of image frames in the image frames, a first height value corresponding to a case that the target object is thrown; and acquiring a throwing position of the target object based on the first height value and the trajectory starting point position of the target object.

Abstract: An object tracking method includes: obtaining at least one image acquired by at least one image acquisition device; obtaining a first appearance feature of a target object and a first spatial-temporal feature of the target object based on the at least one image; obtaining an appearance similarity and a spatial-temporal similarity between the target object and each global tracking object in a currently recorded global tracking object queue; based on determining that the target object matches a target global tracking object based on the appearance similarity and the spatial-temporal similarity, allocating a target global identifier corresponding to the target global tracking object to the target object; determining, using the target global identifier, a plurality of associated images acquired by a plurality of image acquisition devices associated with the target object; and generating, based on the plurality of associated images, a tracking trajectory matching the target object.
