Title:
VIEWING ANGLE PREDICTION METHOD AND APPARATUS, DEVICE, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2024/099314
Kind Code:
A1
Abstract:
A viewing angle prediction method, comprising: on the basis of a head movement trajectory of a user viewing a panoramic video, determining a current predicted viewing angle corresponding to a current clip to be downloaded in the panoramic video (S110); if it is detected that a current head turning action in the head movement trajectory is an invalid action, acquiring a target alternative viewing angle set corresponding to said current clip (S120); and on the basis of the target alternative viewing angle set, performing correction processing on the current predicted viewing angle, and determining a target predicted viewing angle corresponding to said current clip (S130). The beneficial effect is that the predicted viewing angle deviation caused by overlarge head turning amplitude of a user due to non-video factors can be solved, so that the accuracy of viewing angle prediction is improved.
