Embodiment Construction

[0022] The following definitions are used herein for the specification and appended claims. An "AR content creator" is a person who selects markers from a video image, where the markers are intended to be used by the AR client application in image recognition. When an AR content creator interacts with the AR content creation system (eg, enters markers into the system), the AR content creator is a user of the AR content creation system. The "tag database" is a database for storing tags. Since the marker database is mainly used for image recognition, the content of the marker database is any data that can help identify markers in image recognition. Furthermore, when individual markers are identified in a video image, each marker is associated with one or more virtual objects for enhancement with the video image. Accordingly, "marking database for storing marks" here means a database containing: (1) any data capable of assisting in the identification of marks in image recogniti...

Abstract

For an augmented reality (AR) content creation system with a tagging database, when a user requests the system to update the tagging database with the first sub-image of an image, the system calculates the feature richness used to rate the first sub-image and its relative tagging Suitability score for uniqueness of existing markers in the database. When the suitability score is less than the threshold, the image is searched for a second sub-image having a suitability score not less than the threshold and completely containing the first sub-image. Subsequently, the second sub-image, its suitability score and the suitability score of the first sub-image are presented to the user substantially immediately to suggest that the user use the second sub-image instead of the first sub-image as a new sub-image when updating the tagging database. markers in order to increase the feature richness or uniqueness of new markers.

Description

technical field [0001] The present invention relates to determining whether a sub-image selected from an image and proposed by a user of an augmented reality (AR) content creation system is suitable for use as a marker in an AR client application, and giving Users suggest more suitable sub-images. Background technique [0002] AR is a real-time view of a physical scene enhanced with computer-generated virtual objects such as text, images, sounds, etc. Currently, most AR client applications use real-time video images. The AR client application digitally processes the video image to add one or more virtual objects to it. When processing an image, the AR client application matches the image content to reference images stored in the system. This process is generally called image recognition. If a portion of an image is identified as a particular reference image, one or more virtual objects associated with this reference image are enhanced onto the image. Reference images ar...
