A method to identify the location and orientation of an article is provided, the method comprising the steps of: obtaining an image of the article with the article having a known orientation and location relative to a camera; creating a X and Y template edge matrix from the image of the article; creating a plurality of sets of modified template edge matrices, each of the sets of modified template edge matrices being an X and Y template edge matrix with the article in a different orientation; capturing a digital visual image containing the article, the digital image being a matrix of pixels; creating X and Y article edge matrices from the matrix of pixels; quantifying difference between each of the sets of modified template edge matrices and the X and Y article edge matrices with the modified template edge matrices placed at a plurality of locations within the bounds of the article edge matrices; and identifying the location and orientation of the article as the orientation of the article represented by the set of modified template edge matrices at the location within the bounds of the X and Y article edge matrices with the minimal quantified differences between the modified template edge matrices and the X and Y article edge matrices. |
