1. A method for calibrating a sensor of an autonomous vehicle, the method comprising:
receiving, by the autonomous vehicle, a version of a calibration map, wherein the calibration map is a virtual representation of a calibration scene and includes a ground truth feature of a calibration target in the calibration scene, the calibration map is generated based on scene data from a detector in the calibration scene and is periodically updated so that a new version of the calibration map is generated based on new scene data from the detector;
determining, by the autonomous vehicle based on the version, whether the calibration scene has an error that would interfere with calibrating the sensor;
in response to determining that the calibration scene does not have the error, navigating in the calibration scene to allow the sensor to capture one or more features of the calibration target; and
calibrating the sensor based on the one or more features captured by the sensor and the ground truth feature.
