Abstract

When examining current process of object tracking and search, objects were tracked by extracting them from image that was inputted through fixed single camera and objects were recognized through Zoom function to know detailed information on objects tracked. This study proposed system that expresses information on area that can seek and recognize object tracked as augmented reality by recognizing and seeking object by using multi camera. The result of experiment on proposed system showed that the number of pixels that was included in calculation was remarkably reduced and recognition rate of object was enhanced and time that took to identify information was shortened. Compared with existing methods, this system has advantage of better accuracy that can detect the motion of object and advantage of shortening time that took to detect motion.

현재의 객체 추적과 검색의 과정을 보면 고정된 단일 카메라를 통해 입력받은 영상에서 객체를 추출하여 추적하고, 추적된 객체의 구체적인 정보를 알기 위해 줌(Zoom) 기능으로 객체를 인식하는 과정이었다. 본 논문은 다중카메라를 이용하여 객체를 추적하고, 인식하는 것으로써 추적된 객체에 대해 검색인식가능한 영역에 대한 정보를 증강현실로 나타내는 시스템을 제안한다. 제안 시스템의 실험결과를 보면 연산에 포함된 픽셀 수가 현저히 줄어들고, 객체의 인식률이 향상되고, 정보 확인 시간도 단축되었다. 그리고 기존 방법과 비교하여 객체의 움직임을 검출하는 정확성은 물론 움직임 검출에 소요되는 시간도 단축되어 개선된 성능을 보였다.
