  • Real-time acceleration sensor calibration apparatus for measuring movement of vehicle and acceleration sensor calibration method using the same
    Patent number: 10810861
    Abstract: Provided are a real-time acceleration sensor calibration apparatus for measuring a movement of a vehicle and an acceleration sensor calibration method, the acceleration sensor calibration apparatus including an acceleration sensor configured to measure a triaxial acceleration value, a gyroscope configured to measure a triaxial angular velocity value, an acceleration data calibrator configured to primarily transform a vector of the measured acceleration value using a gravity vector calculated based on the triaxial acceleration value and the triaxial angular velocity value measured by the acceleration sensor and the gyroscope, and a communicator configured to transmit information related to the movement of the vehicle to a server based on calibrated acceleration data.
