Assignee: DALIAN UNIVERSITY OF TECHNOLOGY
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 5:
6. A system for adjusting user field of view (FoV) in a three-dimensional VR scene, comprising:
a scene picture acquisition module configured to acquire two consecutive frames of scene pictures during a period of a user experiencing a VR scene by using a VR device;
a projected scene flow vector determination module configured to determine a projected scene flow vector on the basis of the two consecutive frames of scene pictures;
a virtual scene graph generation module configured to generate a virtual scene graph of the two consecutive frames of scene pictures;
a projected scene flow value calculation module configured to determine a projected scene flow value of the virtual scene graph on the basis of the projected scene flow vector;
a peripheral vision pixel determination module configured to determine a peripheral vision pixel of the virtual scene graph;
a projected scene flow average value calculation module configured to calculate a projected scene flow average value of the peripheral vision pixel on the basis of the projected scene flow value of the virtual scene graph; and
a user FoV adjustment module configured to dynamically adjust a user FoV on the basis of the projected scene flow average value, a maximum value of the projected scene flow average value corresponding to a smallest user FoV, and a minimum value of the projected scene flow average value corresponding to a largest user FoV.
