APPARATUS AND METHOD FOR TRACKING AUGMENTED REALITY CONTENT
First Claim
1. A method of tracking augmented reality content, comprising:
- recognizing an augmented reality marker from an input image and calculating a position and posture of the recognized augmented reality marker;
calculating a position and posture of augmented reality content corresponding to the augmented reality marker by using the calculated position and posture of the augmented reality marker;
synthesizing the augmented reality content with the input image by using the calculated position and posture of the augmented reality content, and displaying the synthesized image;
updating the position and posture of the augmented reality content by using a 6-axis sensor when the augmented reality marker is not recognized in the input image; and
synthesizing the augmented reality content with the input image by using the updated position and posture of the augmented reality content, and displaying the synthesized image.

Abstract
Provided are an apparatus and method for tracking augmented reality content using a mobile sensor. The method includes recognizing an augmented reality marker from an input image and calculating a position and posture of the recognized augmented reality marker, calculating a position and posture of augmented reality content corresponding to the augmented reality marker using the calculated position and posture of the augmented reality marker, synthesizing the augmented reality content with the input image using the calculated position and posture of the augmented reality content, and displaying the synthesized image, updating the position and posture of the augmented reality content using a 6-axis sensor when the augmented reality marker is not recognized in the input image; and synthesizing the augmented reality content with the input image using the updated position and posture of the augmented reality content, and displaying the synthesized image.

5. An apparatus for tracking augmented reality content, comprising:
-
a marker recognizer configured to recognize an augmented reality marker from an input image; a calculator configured to calculate a position and posture of augmented reality content corresponding to the augmented reality marker using a position and posture of the recognized augmented reality marker; an image output unit configured to synthesize the augmented reality content with the input image by using the calculated position and posture on the augmented reality content, and display the synthesized image; and a 6-axis sensor configured to measure position and posture changes of the apparatus for tracking the augmented reality content, wherein the calculator updates the position and posture of the augmented reality content by using the calculated position and posture changes measured by the 6-axis sensor when the augmented reality marker is not recognized in the input image, and the image output unit synthesizes the augmented reality content with the input image by using the updated position and posture of the augmented reality content and displays the synthesized image. - View Dependent Claims (6, 7, 8)
