Abstract
A method for adjusting a mirror. The method includes using a camera to capture an image of an object, locating a suitable region in the image, obtaining a first midline between a reference line in the suitable region and a top of the object in the suitable region, obtaining a second midline of the image, comparing the first and second midlines to determine whether the two midlines overlap, outputting a comparison signal upon the condition that the two midlines do not overlap, and directing a driving apparatus to move the mirror to adjust a height of the mirror according to the comparison signal.
