Assignee: SONY GROUP CORPORATION
Field: Measurement (Instruments)
Classification: CPC G | IPC G

Claim 0:
1. An information processing device, comprising
circuitry configured to detect a stationary attitude measurement value; and
a central processing unit (CPU) configured to:
calculate a gravity direction from information of acceleration in the stationary attitude measurement value;
calculate a component related to autorotation of earth in an angular velocity of the stationary attitude measurement value as an autorotation component of a sensor coordinate system with reference to the circuitry based on the gravity direction, absolute direction, and information of latitude;
calibrate the circuitry based on:
the stationary attitude measurement value that is a measurement value detected by the circuitry and information related to an arrangement of the circuitry in a stationary attitude, and
the autorotation component of the sensor coordinate system with reference to the circuitry.
