1. A method for aligning a calibration device with a vehicle based on a wheel aligner, wherein:
the wheel aligner comprises at least one image sensor and a computer communicatively connected to the at least one image sensor;
the method comprises the following steps:
controlling, by the computer, the at least one image sensor to image a vehicle-mounted target on the vehicle, and processing the obtained image to determine a position of the vehicle;
controlling, by the computer, the at least one image sensor to image a reference target on the calibration device, and processing the obtained image to determine a position of the calibration device; and
determining, by the computer, an adjusting mode of the calibration device based on the position of the vehicle and the position of the calibration device, so that the calibration device is aligned with the vehicle according to an anticipated position or direction;
wherein the at least one image sensor comprises at least one first image sensor and at least one second image sensor; and wherein:
the step of controlling, by the computer, the at least one image sensor to image a vehicle-mounted target on the vehicle, and processing the obtained image to determine a position of the vehicle comprises: controlling, by the computer, the at least one first image sensor to capture a first image from the vehicle-mounted target on the vehicle, and processing the first image to determine the position of the vehicle; and
the step of controlling, by the computer, the at least one image sensor to image a reference target on the calibration device, and processing the obtained image to determine a position of the calibration device comprises: controlling, by the computer, the at least one second image sensor to capture a second image from the reference target on the calibration device, and processing the second image to determine the position of the calibration device;
wherein the wheel aligner comprises a bracket; and the at least one first image sensor and the at least one second image sensor are mounted on the bracket;
wherein the at least one first image sensor is disposed at both ends of the bracket, and the at least one second image sensor is disposed at middle of the bracket; and
the reference target on the calibration device is disposed on the side of the calibration device departed from the vehicle and facing the bracket.
