Vehicle calibration method and calibration device

The invention provides a vehicle calibration method and device, and the method comprises the steps: determining a first calibration model which comprises a first calibration workshop model, a first marker model and a first vehicle model, and the first calibration workshop model is a three-dimensional model of a first calibration workshop, the first marker model is a three-dimensional model of a first marker, and the first vehicle model is a three-dimensional model of a first vehicle; a sensor in the first vehicle model is calibrated in the first calibration model, or whether a first calibration parameter in the first vehicle model is accurate or not is determined in the first calibration model, and the first calibration parameter is a calibration parameter to be verified. The calibration rate and the verification efficiency of the calibration parameters can be improved.
