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.

If a controller determines the calculation of a measured vehicle body velocity is possible, the controller calculates the measured vehicle body velocity as an estimated vehicle body velocity to conduct update processing for a K table and an AB table. If the controller determines the calculation of the measured vehicle body velocity is impossible, the controller extracts a conversion coefficient from the K table based on a detected running state while extracting a sensitivity coefficient and an offset coefficient from the AB table based on the temperature by a temperature sensor. The vehicle mounted apparatus calculates an axle pulse-based vehicle body velocity from the extracted conversion coefficient while calculating an acceleration-based vehicle body velocity from the extracted sensitivity coefficient and offset coefficient. The vehicle mounted apparatus calculates the estimated vehicle body velocity by weighting the calculation values of the axle pulse-based vehicle body velocity and the acceleration-based vehicle body velocity.
