Claim Text:
1. A computer-aided method for enabling an augmented reality application resident on a computing device to identify a real world trigger item, the method comprising: capturing, by a processor, an image of a real world trigger item from a series of frames of a video based on geographical information associated, with a location where the video was captured; identifying indexed feature points of a known candidate trigger item stored in a database that match feature points of the real world trigger item; performing a geometric consistency evaluation of the feature points of the real world trigger item, including comparing an overall shape of a composite of individual tiles of the real world trigger item to an overall shape of each of the matching feature points of the known candidate trigger item; performing a weighted factor evaluation of the feature points of the real world trigger item, including identifying a required set of feature points for the real world trigger item and determining that the matching feature points of the known candidate trigger item include the required set of feature points; determining, by the processor, a percentage of the matching feature points of the known candidate trigger item relative to a total number of indexed feature points of the known candidate trigger item; determining whether the determined percentage is equal to or greater than a percentage threshold; in response to a determination that the determined percentage is equal to or greater than the percentage threshold, selecting an augmented reality scenario associated with the real world trigger; and presenting, by the processor, the augmented reality scenario onto a display of the computing device by overlaying augmented reality content onto the series of frames of the video.
