Abstract:
1. An augmented reality system, comprising: a video source, the video source residing at a location and producing an image; at least one encoded marker residing within the image, wherein the encoded marker is formed to store data within a matrix surrounded by a substantially opaque frame; a marker detector, coupled to the video source, adapted to derive encoded data from the marker residing within the image; a database; and a localization processor adapted to receive data from the marker detector and to generate data regarding location and orientation of the marker, the localization processor retrieving information from the database that is related to the location and orientation of the marker, the localization processor making the information retrieved from the database available to a user, wherein the frame of each marker is formed so as to have an exterior edge string and an interior edge string, the tracker calculating relative lengths of exterior and interior edge strings to establish the presence of a marker within an image.
