Apparatus and method for recognizing position using camera
First Claim
1. A location awareness apparatus for recognizing a position using a camera, comprising:
- an image capturing means for photographing a position identification tag using a camera;
a distance measuring means for measuring a distance to a position identification tag;
an incident angle measuring means for measuring a photographing angle at a visual point of photographing a position identification tag by the image capturing means;
an image analyzing means for reading the photographed image from the image capturing means, and requesting location information corresponding to the read information to a position recognition server; and
a location recognizing means for estimating a current location using the distance to the position identification tag, which is measured by the distance measuring means, the photographing angle of the position identification tag, which is measured by the incident angle measuring means, and the location information corresponding to the read information by the image analyzing means.
