Augmented reality system

摘要

A book for use in an augmented reality system comprises a plurality of leaves, each side forming a page of the book, with each page comprising a fiduciary marker. The book also includes a cover having larger dimensions than the book's leaves. Thus, the cover's extremhities extend beyond the outer edges of the pages. The inside of the cover comprises a first high contrast pattern along at least a first such extremity. An entertainment device for use in the augmented reality system comprises input means to receive a video image of the book, and image processing means to estimate a position and orientation of the book from a fiduciary marker of the book captured in the video image, to estimate a position and orientation of the first high contrast pattern, and to distinguish between one or more leaves of the book being turned independently of the cover of the book.

主权项

1. An entertainment device for use in an augmented reality system, comprising:
input means for receiving a video image of a book; first image processing means for estimating a position and orientation of the book from a fiduciary marker of the book captured in the video image, and estimating a position and orientation of a turning leaf of the book captured in the video image; and second image processing means for estimating a position and orientation of a first high contrast pattern on an extremity of an inside cover of the book captured in the video image; and in which at least one of the first and second image processing means is operable to detect whether the position and orientation of the turning leaf and the cover of the book move in a corresponding manner; and at least one of the first and second image processing means is operable to distinguish between turning of the cover of the book and turning the leaves of the book independently of the cover of the book, in response to whether or not the position and orientation of the turning leaf and the cover of the book are detected to move in a corresponding manner.
