Method of positioning by using image
First Claim
1. A method of positioning by using image, using an image-collecting device with a known angle of view to gain a digital image, a pixel matrix of the digital image being defined as the known angle of view and a gap between every two adjacent pixels of each horizontal line and each longitudinal line being an equally divided angle of the known angle, a displaying objective shown on a image sensor and having a datum point of computing of a position angle, a camera lens having a principal axis directing to the datum point such that a calculating unit can compute an angle formed between the displaying objective and the principal axis.

Abstract
A method of positioning by using image uses an image-collecting device with a known angle of view to gain a digital image. A pixel matrix of the digital image is defined as the known angle of view and a gap between every two adjacent pixels of each horizontal line and each longitudinal line is an equally divided angle of the known angle. A displaying objective is shown on an image sensor and has a datum point of computing of a position angle. A camera lens has a principal axis directing to the datum point such that a calculating unit can compute an angle formed between the displaying objective and the principal axis.
