knowing the time Tn_void for idle to pass through phase n, the time Tn+1_void for pass through phase n+1;
knowing the half-load time Tn_half required to pass through stage n, the time Tn+1_half required to pass through stage n+1; knowing that the time Tn currently required to pass through phase n is between Tn_void and Tn_half, the predicted time to pass through phase n+1 is:
Tn+1＝Tn+1_half+(Tn-Tn_half)*(Tn+1_void-Tn+1_half)/(Tn_void-Tn_half)；
calculating and adjusting the playing speed of the VR film according to the pose data information comprises the following steps:
the climbing section of the roller coaster adopts a traction mode, namely, 0-2 sections are of fixed duration, and a fixed video is played;
setting the playing speed of n to n+1 segments of videos: when the vehicle is half-loaded, the video playing speed is V0, the time required by n to n+1 sections is Tn+1_half, and then the playing speed of n to n+1 sections at the moment is:
V1＝(Tn+1_half/Tn+1)*V0。
5. an electronic device comprising a memory and a processor, the memory having stored thereon a computer program, characterized in that the processor, when executing the computer program, implements the method according to any of claims 1 to 3.
6. A computer readable storage medium, on which a computer program is stored, which computer program, when being executed by a processor, implements the method according to any of claims 1 to 3.
