1. An encoding acceleration method of cloud VR (virtual reality) video, the method comprising:
obtaining a center point of a current frame as an identifier of the current frame, wherein the center point is determined according to a sensor data of IMU (Inertial Measurement Unit);
constructing one or more reference frame candidates for encoding of the current frame based on the center point of the current frame;
selecting a specific reference frame among the one or more reference frame candidates based on the sensor data of IMU;
selecting a prediction mode for encoding the current frame based on information included in the specific reference frame; and
encoding the current frame based on the selected prediction mode,
wherein the IMU includes at least one of accelerometers, gyroscopes, and magnetometers.
