Vision-based augmented reality system using invisible marker

A vision-based augmented reality system using an invisible marker, comprising:

• a visible-ray camera for capturing target object (TO) including an infrared marker (IM) drawn by an invisible infrared light-emitting material;
• an infrared-ray camera for capturing the IM included in the TO;
• and
• an image processing system for receiving an image of the infrared marker from the infrared-ray camera, receiving an image of the TO from the visible-ray camera, separating the image of the infrared marker and the image of the TO from each other, 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.

A vision-based augmented reality system using an invisible marker, comprising:

• an infrared-ray camera for capturing a target object (TO) having an infrared marker drawn by an invisible infrared light-emitting material;
• a visible-ray camera for capturing the TO;
• and
• 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 based on the tracked position and pose,
• wherein the image processing system separates an image of the visible-ray camera and an image of the infrared-ray camera from each other in receiving the image of the visible-ray camera and the image of the infrared-ray camera, and renders the virtual image on an image captured by the visible-ray camera.

A vision-based augmented reality system using an invisible marker, comprising:

• a visible-ray camera for capturing a target object (TO) including an infrared marker (IM) drawn by an invisible infrared light-emitting material;
• an infrared-ray camera for capturing the IM included in the TO;
• an optical axis converter for changing viewing point of at least one of the visible-ray camera and the infrared-ray camera;
• and
• an image processing system for rendering a virtual image using an image captured by the infrared-ray camera, an image captured by the visible-ray camera and IM;
• wherein the image processing system receives an image of the infrared marker from the infrared-ray camera, receives an image of the TO from the visible-ray camera, separates the image of the infrared marker and the image of the TO from each other, monitors position and pose of the IM associated with the infrared-ray camera, tracks position and pose of the TO based on position and pose of the IM, and renders the virtual image to the TO image.

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;
• a visible-ray camera for capturing the TO;
• 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 based on the tracked position and pose, and
• an output unit for displaying the rendered virtual image;
• wherein the image processing system separates an image of the visible-ray camera and an image of the infrared-ray camera from each other in receiving the image of the visible-ray camera and the image of the infrared-ray camera, and renders the virtual image on an image captured by the visible-ray camera.
