摘要

PURPOSE: A method for providing tangible markerless AR(Augmented Reality) and a system thereof are provided to update a key frame and use the updated key frame to estimate a page posture. CONSTITUTION: An image collecting unit collects an image about learning subject(S310). A feature point extracting unit extracts a feature point from a collected image(S302). When a recognized page is wrong, a page recognizing unit recognizes the current page(S304,S306). A page tracking unit tracks a page posture(S308). When the posture is correctly estimated, a key frame updating unit updates a key frame according to a user environment(S310,S312).
