Viewing angle prediction method, device, and storage medium

An electronic device, comprising:

• one or more processors;
• and
• a storage apparatus configured to store one or more programs, wherein
• the one or more programs, when executed by the one or more processors, cause the one or more processors to:
• determine a current predicted viewing angle corresponding to a current to-be-downloaded clip in a panoramic video based on a head movement trajectory of a user viewing the panoramic video;
• acquire a target candidate viewing angle set corresponding to the current to-be-downloaded clip in response to detecting that a current head turning action in the head movement trajectory is an invalid action;
• and
• perform correction processing on the current predicted viewing angle and determining a target predicted viewing angle corresponding to the current to-be-downloaded clip based on the target candidate viewing angle set,
• wherein acquire the target candidate viewing angle set corresponding to the current to-be-downloaded clip comprises:
• acquire a panoramic video header file corresponding to the panoramic video, wherein the panoramic video header file comprises a candidate viewing angle set corresponding to each clip of the panoramic video, the candidate viewing angle set is determined based on a clip content feature corresponding to each clip, and/or an actual viewing angle of the user;
• and
• obtain the target candidate viewing angle set corresponding to the current to-be-downloaded clip based on the panoramic video header file.

A non-transitory storage medium, with computer-executable instructions stored thereon, wherein the computer-executable instructions, when executed by a computer processor, cause the computer processor to:

• determine a current predicted viewing angle corresponding to a current to-be-downloaded clip in a panoramic video based on a head movement trajectory of a user viewing the panoramic video;
• acquire a target candidate viewing angle set corresponding to the current to-be-downloaded clip in response to detecting that a current head turning action in the head movement trajectory is an invalid action;
• and
• perform correction processing on the current predicted viewing angle and determining a target predicted viewing angle corresponding to the current to-be-downloaded clip based on the target candidate viewing angle set,
• wherein acquire the target candidate viewing angle set corresponding to the current to-be-downloaded clip comprises:
• acquire a panoramic video header file corresponding to the panoramic video, wherein the panoramic video header file comprises a candidate viewing angle set corresponding to each clip of the panoramic video, the candidate viewing angle set is determined based on a clip content feature corresponding to each clip, and/or an actual viewing angle of the user;
• and
• obtain the target candidate viewing angle set corresponding to the current to-be-downloaded clip based on the panoramic video header file.
