Abstract

We have studied depth conversion of a reconstructed image by means of recombination of the elemental images in the integral imaging system for 3D display. With the recombination, depth conversion to the pseudoscopic, the orthoscopic, the real or the virtual as well as to arbitrary depth without any distortion is possible under proper conditions. The conditions on the recombinations for the depth conversion are theoretically derived. The reconstructed images using the converted elemental images are presented.

3차원 영상 재생을 위한 집적결상법에서 기본영상의 재조합을 통한 재생영상의 깊이변환에 관하여 연구하였다. 렌즈 배열 또는 카메라 배열 등을 통하여 획득된 영상 배열을 적절한 조건 하에서 재조합하여 재생함으로써 재생영상의 깊이에 대해 도치(pseudoscopic) 영상 또는 정치(orthoscopic) 영상, 허상, 실상 뿐만 아니라 임의의 깊이로의 왜곡 없는 변환이 가능하다. 본 논문에서는 각 변환에 대한 재조합 조건을 이론적으로 유도하고 실험을 통하여 확인하였다.
