Abstract
A sensor calibration method includes: location information of a target detected by a radar is matched against map information to determine a calibration value of the radar, and then location information of a pixel of a target corresponding to the camera in a global coordinate system is determined based on calibrated radar measurement data so as to further determine a calibration value of the camera. In this way, for a roadside sensing system that includes the single radar and the single camera, manual field calibration is no longer required.
