Title:
REAL-TIME ACCELERATION SENSOR CORRECTION DEVICE FOR MEASURING VEHICLE MOVEMENT, AND ACCELERATION SENSOR CORRECTION METHOD USING SAME
Document Type and Number:
WIPO Patent Application WO/2019/172461
Kind Code:
A1
Abstract:
The present invention may provide a real-time acceleration sensor correction device for measuring vehicle movement and an acceleration sensor correction method, the device comprising: an acceleration sensor for measuring a three-axis acceleration value; a gyroscope for measuring a three-axis angular velocity value; an acceleration data correction unit for performing primary conversion of an acceleration value vector measured using a gravity vector calculated on the basis of a three-axis acceleration value and a three-axis angular velocity value which are measured by the acceleration sensor and the gyroscope; and a communication unit for transmitting vehicle movement-related information to a server on the basis of corrected acceleration data.
