The Stereoscopic Analyzer — An image-based assistance tool for stereo shooting and 3D production

Abstract

The paper discusses an assistance system for stereo shooting and 3D production, called Stereoscopic Analyzer (STAN). A feature-based scene analysis estimates in real-time the relative pose of the two cameras in order to allow optimal camera alignment and lens settings directly at the set. It automatically eliminates undesired vertical disparities and geometrical distortions through image rectification. In addition, it detects the position of near- and far objects in the scene to derive the optimal inter-axial distance (stereo baseline), and gives a framing alert in case of stereoscopic window violation. Against this background the paper describes the system architecture, explains the theoretical background and discusses future developments.
