Geometrical analysis of puppet-theater and cardboard effects in stereoscopic HDTV images

摘要: A fundamental element of stereoscopic image production is to geometrically analyze the conversion from real space images by binocular parallax under various shooting and viewing conditions. This paper reports on this analysis, particularly setting optical axes three-dimensional (3-D) cameras, which has received little attention in past. First, we identified conditions for that maintain linearity during images. We then clarified, geometrical terms, also puppet-theater effect cardboard occur. The results showed parallel camera configuration, are kept each other, does not produce as apparent magnification (lateral magnification) a target dependent distance. However, toed-in where distance, may effect. shown be likely occur both configurations defining phenomenon ratio depthwise reproduction (depth magnification). Lastly, relationship between analysis those subjective evaluation experiments. need closer examination using many more
