1. A throwing position acquisition method, performed by a computer device, the throwing position acquisition method comprising:
acquiring image frames of a target video, the target video being a video comprising a thrown target object;
acquiring a projectile position in each image frame, the projectile position being a position of an image corresponding to the target object in each image frame;
acquiring a trajectory starting point position of the target object based on the projectile position in each image frame, the trajectory starting point position being a starting point position of a projectile trajectory obtained 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, the at least one group of image frames respectively comprising at least two image frames; 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.
