Abstract

Evaluation of the effect of radial distortion for a holographic stereogram demands conducting an experiment which comprises rendering of a 3D obejc, acquisition of perspective images, rearrangement of the acquired images for hogel images and quality assessment of the observing image reconstructed from the holographic stereogram. We propose numerical implementation of this evaluation by a specially developed algorithm for modeling of all required steps. The modeling is done by using a numerical model of an optical engine for generation of radially distorted hogel images at various degrees of distortion. The distorted images are used to form the holographic stereogram and to make the numerically reconstructed images from the holographic stereogram which are observed by an observer at desired location. The reconstructed images are compared by using PSNR.

방사 왜곡이 홀로그래픽 스테레오그램에 미치는 영향을 알아보기 위해, 가상의 3차원 객체를 렌더링하고, 이 객체로부터 원근 투영 이미지를 획득하였다. 획득된 원근 투영 이미지를 재배열 하여 hogel 이미지를 만들고 복원되는 영상을 확인하기 위해 홀로그래픽 스테레오그램의 수학적 복원 알고리즘을 제안하였다. 광학 엔진에 의해 발생 할 수 있는 방사 왜곡을 포함하는 hogel 이미지를 왜곡 정도를 달리하여 만들고, 수학적 복원 알고리즘을 이용하여 복원 하였고, 복원된 영상을 PSNR을 이용하여 비교 하였다.
