Determining pose for use with digital watermarking, fingerprinting and augmented reality
First Claim
Patent Images
1. A method comprising:
- receiving imagery captured by a device sensor, in which the device sensor comprises an image or video camera;
analyzing the imagery to decode digital watermarking therefrom, in which the digital watermarking comprises orientation attributes;
determining orientation information from the orientation attributes, the orientation information being associated with a capture position of the device sensor relative to an imaged subject;
providing the orientation information for use by an augmented reality (AR) system; and
using one or more configured processors, refining the orientation information determined from the orientation attributes with image homography, in which the orientation information is utilized as a starting pose for the image homography.

Abstract
Image recognition and augmented reality experiences utilize auxiliary data extracted from an image or video, or image fingerprints, or a combination of both. One claim recites a method comprising: receiving a plurality of imagery frames captured by a device sensor; identifying a plurality of key points in each of the plurality of imagery frames; resolving image pose by utilizing relative relationships of the key points between different frames of the plurality of frames; modifying imagery of at least one of the plurality of frames based on resolved image pose; and deriving a fingerprint from modified imagery. Of course other claims and combinations are provided as well.

9. A mobile device comprising:
-
a device sensor comprising an image or video camera; memory storing instructions; one or more processors configured by the instructions for; analyzing imagery captured by said device sensor to extract an encoded signal therefrom, in which the encoded signal comprises orientation attributes; determining orientation information from the orientation attributes, the orientation information being associated with a capture position of said device sensor relative to an imaged subject; providing the orientation information for use by an augmented reality (AR) system; and adapting the orientation information determined from the orientation attributes with image homography, in which the orientation information is utilized as a starting pose for the image homography. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)
