초록

본 논문에서는 집적영상기술을 이용한 광학적 3D 영상 상관기의 구현 방법을 제안한다. 제안하는 방법에서는 참조 3D 물체와 신호 3D 물체의 요소 영상들이 렌즈 배열을 통하여 얻어지고 이 요소 영상들을 디스플레이 패널에 다시 표시하여 출력 평면에서 광학적으로 고해상도 출력 평면 영상을 얻는다. 이렇게 얻어진 참조 및 신호 물체의 출력 평면 영상에 대하여 상호 상관관계를 수행하여 3D 물체를 인식한다. 제안한 방법은 기존 방법과 비교하여 높은 해상도의 출력 평면 영상을 사용하기 때문에 정확한 3D 물체 인식이 가능하며, 실시간 3D 물체 인식 시스템을 광학적으로 구현할 수 있다. 제안하는 방법의 유용함을 보이기 위하여 광학 실험을 수행하고 그 결과를 보고한다.

In this paper, we propose an implementation method of 3D image correlator using integral imaging technique. In the proposed method, elemental images of the reference and signal 3D objects are recorded by lenslet arrays and then reference and signal output plane images with high resolution are optically reconstructed on the output plane by displaying these elemental images into a display panel. Through cross-correlations between the reconstructed reference and the single plane images, 3D object recognition is performed. The proposed method can provide a precise 3D object recognition by using the high-resolution output plane images compared with the previous methods and implement all-optical structure for real-time 3D object recognition system. To show the feasibility of the proposed method, optical experiments are carried out and the results are presented.
