Title:
情報処理装置および情報処理方法、並びにプログラム
Document Type and Number:
Japanese Patent JP7347431
Kind Code:
B2
Abstract:
The present disclosure relates to an information processing apparatus, an information processing method, and a program, the information processing apparatus and the information processing method making it possible to appropriately combine observation values of a plurality of sensors according to the noise characteristics of the plurality of sensors and a condition for the observation values.An Allan variance is calculated as the characteristics of each of the plurality of sensors. A time window length for an Allan variance is specified as a condition used when the observation values of the plurality of sensors are combined. A weight for each of the plurality of sensors is calculated such that a sum of the Allan variances for the specified time window length is smallest. The respective observation values of the plurality of sensors are combined using a sum of products of the observation values of the plurality of sensors and the weights each calculated for a corresponding one of the plurality of sensors. The present disclosure is applicable to a multi-IMU.
