Abstract:
1. A method for producing tie points for use in stereo-matching of stereoscopic images, the method comprising: a) obtaining at least two sets of stereoscopic images, each one of said at least two sets including images that are taken from different angles, each one of said at least two sets including images taken at different time with respect to the images of the other sets; b) determining at least two groups of images, each one of said groups including at least two images of at least two of said sets or are derived from images of said sets; and c) for each one of said groups, calculating a respective optimal entities list including: whereby entities of the optimal entity lists are used as tie points for stereo-matching at least two images, each one being or derived from different one of said at least two groups thereby giving rise to at least one pair of stereo-matched stereoscopic images.
