Development of an omnidirectional stereo vision system
Aliz-Eva Nagy, Szakats Istvan, Tiberiu Mariţa, Sergiu Nedevschi · 2013
Although stereo systems built up of omnidirectional cameras offer the possibility of providing information for a 360 grade field of view, the research in the field is still in an early stage compared to perspective systems. We provide in this study an extensive overview on existing techniques for camera calibration, stereo rectification, stereo matching methods and 3D depth reconstruction on omnidirectional images. A comparison of methods, together with a few ideas of improvement is presented, establishing an equivalency, and transformation between an omnidirectional and a perspective vision system.
