Claim 0:
1. A method for adjusting user field of view (FoV) in a three-dimensional virtual reality (VR) scene, comprising:
acquiring two consecutive frames of scene pictures during a period of a user experiencing a VR scene by using a VR device;
determining a projected scene flow vector on the basis of the two consecutive frames of scene pictures;
generating a virtual scene graph of the two consecutive frames of scene pictures;
determining a projected scene flow value of the virtual scene graph on the basis of the projected scene flow vector;
determining a peripheral vision pixel of the virtual scene graph;
calculating 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
dynamically adjusting 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.
