Analysis of Space Roundness with Converged Stereo Camera for Realistic 3D Content Production

Abstract

It is necessary to match the viewpoint of the camera with user’s viewpoint during stereoscopic image production. In this matching process, distortion occurs as a result of optical errors. Accordingly, sweetening process is needed to reinterpret the geometric element of an image and minimize eyestrain. Particularly, the phenomenon of space roundness which occurs in converged image contents by the convergence method, causes eye-strain according to the viewing position. In addition, the paradoxical effects meaning the difference in spatial information caused by the combination of different depth information during CG/real 3D image synthesis can occur. This paper presents an effective method for 3D synthesis by understanding the cause of roundness in the process of synthesizing real stereo images with the convergence method and the CG object. The proposed method is applicabale for high-quality 3D stereoscopic images production by predicting and interpreting inconsistency in spatial structure relation between CG and real images.
