Method and system for haptic interaction in augmented reality

The present invention relates to a method and system for haptic interaction in augmented reality. More specifically, the present invention is to effectively remove noise in the actual image obtained through the image acquisition device for stable and smooth haptic interaction in augmented reality and to minimize the discontinuity of the force generated during the haptic interaction Haptic interaction method and system in augmented reality. According to an embodiment of the present invention, a marker detection unit which receives an image of a real environment including a marker and detects the marker included in the image, a marker position extraction unit which extracts the position of the detected marker, and the marker position extraction unit A visual rendering unit including a noise removing unit removing noise from the position information of the marker and a virtual object enhancer configured to augment and output the virtual object corresponding to the marker at the position of the marker; And a motion estimator for estimating the movement of the marker according to a time interval for haptic rendering based on the position information of the marker received from the noise removing unit, and corresponding to the position of the marker estimated according to the motion estimating unit. Augmented reality system including a collision detection unit for detecting whether a collision between the virtual object and the end point of the haptic device, and a reaction force calculation unit for calculating a reaction force to be provided through the haptic device in accordance with the determination of the collision detection unit And it provides a method for providing augmented reality for this.
