System and method of image augmentation

摘要

A book for use in an augmented reality system comprises a first page on a first leaf of the book comprising a first fiduciary marker for indicating the orientation of the book to a recognition system, and a second page on a second leaf of the book comprising a second fiduciary marker for indicating the orientation of the book to a recognition system and also page marker for indicating the page number of the second page to the recognition system, wherein the orientation of the page marker is ambiguous without reference to a fiduciary marker, and the page marker is positioned on the second page closer to an edge of the page than the second fiduciary marker so as to become visible to the recognition system before the second fiduciary marker, as the book is turned to the second page; meanwhile, an entertainment device comprises a video input for receiving captured video frames comprising an image of the book, a fiduciary marker recognition processor operable to recognise the first fiduciary marker printed on the first page of the book and operable to estimate an orientation of the book based upon the recognised first fiduciary marker, and a page marker recognition processor operable to recognise the page marker printed on the second page of the book with reference to the estimated orientation of the book as based upon the recognised first fiduciary marker printed on the first page of the book.
