Abstract
Nonideal stereo videos do not hinder viewing experience in stereoscopic displays. However, for autostereoscopic displays nonideal stereo videos are the main cause of reduced three-dimensional quality causing calibration artifacts and multiview synthesis artifacts. We propose an efficient multiview rendering algorithm for autostereoscopic displays that takes uncalibrated stereo as input. First, the epipolar geometry of multiple viewpoints is analyzed for multiview displays. The uncalibrated camera poses for multiview display viewpoints are then estimated by algebraic approximation. The multiview images of the approximated uncalibrated camera poses do not contain any projection or warping distortion. Finally, by the exploiting rectification homographies and disparities of rectified stereo, one can determine the multiview images with their estimated camera poses. The experimental results show that the multiview synthesis algorithm can provide results that are both temporally consistent and well-calibrated without warping distortion.
