Abstract
The systems and methods may allow mobile computing devices to identify real world trigger items and to cause augmented reality scenarios associated with a real world trigger item to be presented on a display of the mobile computing device. A lookup scheme may identify indexed feature points of known candidate trigger items stored in a database. A number of evaluations occur between the indexed feature points to the feature points found in the real world trigger item. A determination that the feature points of a candidate trigger item matches the feature points of the real world trigger item is made when a confidence threshold is met or exceeded based on at least the look up scheme, weighted factor evaluation, variable threshold evaluation and potentially a geometric consistency evaluation to declare a positive match.
