Spatio-temporal Editing Method and Application in Virtual Reality Video

VR, as a new media video game expression form, differs in its temporal and spatial order from the real world. Through cognitive psychology experiments, data on eye movements and head movements were collected, factors affecting presence and continuity were analyzed, and a spatio-temporal editing design method based on regions of interest (ROI) and transition effects was studied. Then, develop a ROI visualization analysis system, and use successive over relaxation optical flow algorithms to efficiently calculate texture, motion, and depth of field. The experimental results show that continuous editing will inhibit spatial presence and weaken the psychological experience of spatial fusion; the significant position deviation before and after editing and the double significant position design will enhance behavioral exploration and at the same time weaken temporal continuity. Finally, the application practice was carried out through spatio-temporal editing design, which verified the effectiveness of the design method.
