Abstract
A system and method for automatically acquiring a matrix of digital reference images containing landmarks relevant to recognizing and tracking objects in a digital video image is disclosed. In order to virtually insert a digital graphic having a correct pose in a stream of images, an indexed matrix of images of the landmarks in a venue is accumulated. The system and method allow for automated acquisition of new landmarks within a venue, and for the automated expansion of the reference matrix to accommodate reference images indicative of changed conditions within a venue and for reference images of new landmarks. When a landmark is recognized in an image, the graphic reference matrix is queried to obtain a preferred reference image to be used in making a virtual insertion.
