Abstract
A method is provided for generating a three dimensional frame. The method comprises the steps of: retrieving information that relates to a plurality of images of a target captured by two image capturing devices; determining data that will be applied for analyzing objects of interests included in the captured images; calculating disparity between groups of corresponding frames, wherein each of said groups comprises frames taken essentially simultaneously by the two image capturing devices; determining an initial estimation of a disparity range for the frames included in the groups of the corresponding frames; evaluating a disparity range value for each proceeding group based on information retrieved on a dynamic basis from frames included therein, and changing the value of said disparity range when required; and applying a current value of the disparity range in a stereo matching algorithm, and generating a three-dimensional frame for each proceeding group of corresponding frames.
