Abstract:
A movement information calculating device includes a positioning sensor, a velocity sensor, an attitude sensor and processing circuitry. The positioning sensor is configured to calculate a position of the positioning sensor on a movable body. The velocity sensor is configured to calculate a velocity of the movable body. The attitude sensor is configured to calculate an attitude of the movable body. The processing circuitry is configured to calculate a center-of-gravity position and a center-of-gravity velocity of the movable body by using the position, the velocity, and the attitude, and calculate one of a turning center position and a pivoting position of the movable body by using the center-of-gravity position and the center-of-gravity velocity.
