The present invention relates to an azimuth calibration method and apparatus. The method comprises: obtaining information about an azimuth to be calibrated of a first device, and sending a calibration request to a second device; the second device performing azimuth calibration in response to the calibration request, and sending, to the first device, information about a calibrated azimuth obtained after the azimuth calibration; the first device receiving the information about the calibrated azimuth obtained by the second device after the azimuth calibration in response to the calibration request; and obtaining a preset relative azimuth between the first device and the second device, and then performing azimuth calibration according to the information about the azimuth to be calibrated, the information about the calibrated azimuth, and the preset relative azimuth. By means of the azimuth calibration method and apparatus, when azimuth calibration is performed on the first device, it is unnecessary to start the first device to move back and forth in the field. Information about the calibrated azimuth obtained by the second device after azimuth calibration is received, and azimuth calibration can be performed according to the information about the calibrated azimuth, the information about the azimuth to be calibrated of the first device, and the relative azimuth. The calibration process is simplified, and the calibration efficiency is improved.
