Abstract

Variation of the observer's viewing position is one of the major causes of image space distortion in the stereoscopic display. Especially, a large image distortion, which is caused by different depth direction positions of the observer's two eyes, is made by the observer's rotation movement in relation to the center of the screen. This is different from distortion of horizontal and depth directional movement of the observer. In this paper, we analyzed distortion of the image space due to the observer's rotation movement and showed the corrected result of distortion through simulation in the stereoscopic display. Finally, we showed that the distortion shape of the observer's rotation movement is different from horizontal and depth directional movement of the observer.

스테레오 영상에서 관찰자의 위치 변화는 왜곡 발생의 주요 원인이다. 특히, 디스플레이 장치의 중심을 기준으로 한 관찰자의 회전 이동은 관찰자 양안의 수평위치가 다르므로 수평, 전후 이동과는 다른 스테레오 영상의 왜곡이 크게 발생하게 된다. 본 논문에서는 전산모사를 통하여 관찰자의 회전이동에 의한 왜곡을 분석하였고 왜곡 보정결과도 보였다. 마지막으로 관찰자의 회전이동과 수평, 전후 이동의 왜곡형태를 비교를 통하여 두 이동에서 나타나는 왜곡의 형태가 다름을 보였다.
