Abstract
본 논문에서는 가변형 패럴랙스 배리어와 DDC 통신을 이용한 시점 추적형 3D 디스플레이 시스템을 구현하였다. 가변형 패럴랙스 배리어는 4개의 서브 배리어로 구성되며, 관찰자의 위치를 추출하기 위하여 웹 카메라를 이용하였다. 웹 카메라로 부터 추출된 관찰자의 좌표 값은 DDC 통신을 통해 모니터의 전면부에 장착된 가변형 패럴랙스 배리어를 시점에 맞게 전기적으로 이동시키게 된다. 실험을 통해 고정형과 가변형 패럴랙스 배리어 시스템의 성능을 비교하였다. In this paper, we introduce an eye-tracking 3D display system using variable parallax barrier and DDC communication. A barrier of variable parallax barrier composed of 4 sub-barriers and a commercially available web camera is utilized to implement the eye-tracking system. The coordinates of a viewer is extracted from the web camera transfer to 3D display via DDD/CI communication. The variable barrier attached to the LCD moves electrically according to the right eye position for 3D images. This system is compared experimentally with the commercial parallax barrier methods.
