Abstract
A system and method for registering stereoscopic images comprising: obtaining at least two sets of stereoscopic images, each one of the at least two sets including at least two images that are taken from different angles, determining at least two groups of images, each one of the groups including at least two images that are respective images of at least two of the sets or are derived therefrom. For each one of the groups, calculating a respective optimal entities list and stereo-matching at least two images, each one being or derived from different one of the at least two groups and same or different sets, using at least four optimal entities from each one of the optimal entities list, thereby giving rise to at least one pair of registered stereoscopic images.
