초록

다양한 사용자들이 증강 현실을 쉽게 제작하기 위하여 3차원 물체의 추적 및 인식이 가능하도록 하기 위한 물체 등록과정이 직관적이고 간단하여야 한다. 물체 등록에 활용될 수 있는 다양한 3차원 재구성 방법이 개발되었지만, 아직은 실험적인 단계에 있다. 본 논문은 증강 현실 저작 시 다양한 사용자들에게 다양한 환경에서 직관적으로 활용될 수 있도록 하기 위한 3차원 재구성 방법으로써 마커를 활용하는 마커 기반 탠저블 인터페이스를 제안한다. 본 논문에서 제안하는 인터페이스를 이용하여 사용자가 물체의 표면을 직접 접촉함으로써 물체 여러 표면의 3차원 기하학 정보를 획득한다. 이 인터페이스를 이용하여 단순히 그래픽적인 모델링을 위한 3차원 재구성을 하는 것이 아니라 물체의 특징점 정보를 제공함으로써 증강현실에 활용할 수 있도록 한다. 최종적으로 제안하는 방법을 통하여 증강 현실 응용을 보임으로써 제안하는 방법의 효용성을 확인한다.

In order to support simple authoring an application of augmented reality for diverse users, the process for the object registration comprised of tracking and recognizing the object should be accomplished intuitively and simple. Although many 3D reconstruction methods to be applied to the object registration have been developed, the methods have not beyond the experimental level yet. In this paper, we proposed a novel marker-based tangible interfaces for various users to manipulate the object with intuitive and simple approaches during an authoring applications fo augmented reality. The proposed method make use of marker as intuitive interface to obtain 3D geometric information of 3D reconstruction. 3D geometric information of an object surface is acquired by touching the object directly with the proposed tangible interfaces. The tangible interfaces not only support 3D reconstruction for graphical modeling but also offer features information which is used for augmented reality. Finally, we verify efficiency of the proposed method with demonstration of an augmented reality application using the proposed method.
