  • Publication number: 20240328790
    Abstract: There is provided an inertial measurement device that enables, in correcting a shake, appropriate shake correction in consideration of a time lag from observation timing of an IMU until motion of an actuator or the like is controlled, a method of operating an inertial measurement device, an imaging device, a display device, and a program. Detection results are combined and output by a plurality of inertial measurement units (IMUs) of an imaging device body, and angular velocity and acceleration in the future after a predetermined time are output from current angular velocity and acceleration of a main body unit. Future position and attitude of an image sensor are detected on the basis of the future angular velocity and acceleration, and the image sensor is driven such that a shake of the image sensor is absorbed on the basis of the position and attitude as a detection result, thereby correcting the shake of the image sensor. It is applicable to an imaging device.

  • Publication number: 20240310471
    Abstract: The present disclosure relates to an information processing device, an information processing method, and a program each capable of measuring a position and a posture by using sound without bringing discomfort to a user. A spread code signal emitted from each of multiple sound output blocks present at known positions, shifted to a frequency band that is not easily perceivable for a human sense of hearing, and based on a spread code to which spread spectrum modulation has been applied is received. The received spread code signal of a sound signal is reversely shifted. The own absolute position and the own absolute posture are calculated on the basis of the reversely shifted spread code signal, and angular velocity and acceleration detected by an IMU. The present disclosure is applicable to a game controller and an HMD.

  • Publication number: 20240175893
    Abstract: The present disclosure relates to an information processing apparatus, an information processing method, and a program capable of implementing highly accurate motion capture. The posture, speed, and position of the sensor unit are calculated by integrating the angular velocity and the acceleration detected by the sensor unit. Since at least one of the calculated posture, speed, or position of the sensor unit is obtained by integration, the accuracy decreases with the lapse of time, and thus an inference parameter for inferring at least one of the posture, speed, or position of the sensor unit is learned using only a value having a small error with an elapsed time shorter than a predetermined time. The present invention can be applied to a motion capture apparatus.
