Method for generating rotation direction of gyroscope and computer device

A camera for achieving a bullet-time photography effect, comprising:

• one or more processors;
• a memory;
• and
• one or more computer programs, the processors and the memory being connected by a bus, wherein the one or more computer programs are stored in the memory and configured to be executed by the one or more processors, which when being executed by the one or more processors, cause the one or more processors to perform a method for achieving a bullet-time photography effect, comprising:
• capturing a panoramic video using the camera rotating around a shooting target;
• obtaining an acceleration value of an IMU during the capturing, and determining the acceleration value as a first acceleration value;
• filtering the first acceleration value in a world coordinate system to remove a gravitational acceleration to obtain a fourth acceleration value in an IMU coordinate system;
• comparing acceleration components along an X axis, a Y axis and a Z axis of the fourth acceleration value to determine an axis corresponding to a maximum acceleration component;
• and determining a rotation direction of a gyroscope as:
• a direction of a rotation axis when the axis, corresponding to and in the same direction as the maximum acceleration component, rotates towards a camera;
• and
• generating images corresponding to the rotation direction of the gyroscope in the panoramic video on the basis of the rotation direction of the gyroscope.
