Vision-based augmented reality system using invisible marker

A display device, comprising:

• an infrared-ray camera for capturing a target object (TO) having an infrared marker drawn by an invisible infrared light-emitting material;
• an image processing system for monitoring position and pose of the IM from an image of the infrared-ray camera, tracking position and pose of the TO based on the position and the pose of the IM, rendering a virtual image on the TO. and
• an output unit for displaying the rendered virtual image.

A method for vision-based augmented reality using an invisible marker, comprising the steps of:

• (a) capturing target object (TO) including an infrared marker (IM) drawn by an invisible infrared light-emitting material using a visible-ray camera;
• (b) capturing the IM included in the TO using an infrared-ray camera;
• (c) obtaining an image of the visible-ray camera and an image of the infrared-ray camera separately, monitoring position and pose of the IM associated with the infrared-ray camera, tracking position and pose of the TO based on position and pose of the IM, and rendering a virtual image to the TO image.
