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.
Claims9
A mirror comprising:
- a reflecting portion mounted to a stand;
- a camera, a center of a lens of which aligns with a top edge of the reflecting portion;
- a driving apparatus to adjust a location of the reflecting portion on the stand, for changing a height of the mirror;
- a processing unit;
- and
- a storage unit connected to the processing unit, the camera, and the driving apparatus, and storing a plurality of programs to be executed by the processing unit, wherein the storage unit comprises:
- a region detection module analyzing the image to locate a suitable region therein;
- a first location determination module to obtain a first midline between a reference line in the suitable region and a top of the object in the suitable region;
- a second location determination module to obtain a second midline of the image;
- a comparison module to compare the first and second midlines to determine whether the first and second midlines overlap, and output a comparison signal upon the condition that the first and second midlines do not overlap;
- and
- a control module directing the driving apparatus to move the reflecting portion relative to the stand according to the comparison signal.
An adjustment method for a mirror, the adjustment method comprising:
- capturing an image of an object by a camera mounted on the mirror, the lens center of which aligns with the top edge of the mirror;
- analyzing the image to locate 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 first and second midlines overlap, and outputting a comparison signal when the first and second 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.
