Abstract: A sensor calibration method and apparatus are provided Location information of a target detected by the radar (110) is matched against map information to determine a calibration value of the radar (110), and then location information of a pixel of a target corresponding to the camera (120) in a global coordinate system is determined based on calibrated radar measurement data, so as to further determine a calibration value of the camera (120). In this way, for the roadside sensing system (200) that includes the single radar (110) and the single camera (120), manual field calibration is no longer required, which can effectively improve calibration efficiency of sensors in the roadside sensing system (200). This method improves an advanced driving assistance system ADAS capability of a terminal in automatic driving or assisted driving, and may be applied to a vehicle network, for example, V2X, LTE-V, and V2V.
