Provided is an information processing device including: a storage device having a program stored therein; and a hardware processor, wherein the hardware processor executes the program stored in the storage device to: acquire first data for a dimension of position relating to an object represented in a generalized coordinate system; acquire at least second data for a dimension of acceleration from a plurality of inertial sensors attached to the object; and convert the second data into third data for a dimension of acceleration represented in the generalized coordinate system on the basis of the first data.

Information processing device, information processing method, and storage medium

A posture estimation device includes an acquisition part acquires information of angular velocities and accelerations from a plurality of sensors that detects angular velocities and accelerations and that are attached to a plurality of locations on an estimation object, a conversion part that converts information acquired by the acquisition part into information of a standard coordinate system from a sensor coordinate system, an integrating part that calculates an orientation of a reference area of the estimation object as a part of a posture of the estimation object by integrating the converted angular velocities, and a correction part, assuming a representative plane passing through a reference area included in the estimation object, corrects the converted angular velocities of the reference area so that a normal line of the representative plane and an orientation of the reference area calculated by the integrating part approaches to directions that are perpendicular to each other.

Posture estimation device, posture estimation method, and storage medium

In an apparatus for reducing vehicle aerodynamic drag equipped with an air jet device installed at upper and lower positions of a rear of a vehicle and each having a vibrator connected to a diaphragm disposed in an enclosed region and adapted to be driven based on a drive signal to vibrate the diaphragm to jet/suck air through an orifice formed in the region, a vehicle traveling condition is detected, the drive signals for the respective air jet devices are determined independently of each other based on the detected traveling condition, and the vibrators of the respective air jet devices are driven based on the determined drive signals to reduce aerodynamic drag acting on the vehicle.
