Abstract
The present application is applicable to the field of video processing, and provides a method for generating a rotation direction of a gyroscope. The method comprises: obtaining an acceleration value and an angular velocity value of an IMU in real time, taking the acceleration value as a first acceleration value, and estimating an attitude from the IMU to a world coordinate system; converting the first acceleration value from an IMU coordinate system to a world coordinate system to obtain a second acceleration value; in the world coordinate system, filtering a second acceleration, and filtering out a gravitational acceleration to obtain a third acceleration; converting the third acceleration into the IMU coordinate system to obtain acceleration components in the X axis, the Y axis and the Z axis of a fourth acceleration; and determining the rotation direction of the gyroscope according to the acceleration components.
