Title:
SENSOR DATA CALIBRATION
Document Type and Number:
WIPO Patent Application WO/2023/143132
Kind Code:
A1
Abstract:
During a sensor data calibration process, image data, radar data and inertial data at multiple moments during a movement process of a test device are acquired (S100); a motion trajectory of the test device is determined according to the inertial data and the image data, and the movement velocity of the test device under an image reference frame is determined according to the motion trajectory (S102); and the Doppler velocity in the movement process of the test device is determined according to the radar data, and the Doppler velocity and the movement velocity of the test device under the image reference frame are registered so as to calibrate sensor data (S104).
