IMAGE PROCESSING METHOD FOR DETERMINING DEPTH INFORMATION FROM AT LEAST TWO INPUT IMAGES RECORDED USING A STEREO CAMERA SYSTEM

摘要

An image processing method for determining depth information from at least two input images (A1, A2) recorded using a stereo camera system, wherein the depth information is determined from a disparity graph taking into account geometric properties of the stereo camera system, characterized by the following method steps for determining the disparity graph: transforming the input images (A1, A2) into signature images (B1, B2) using a predefined operator; - calculating the costs (C) on the basis of the signature images (B1, B2) using a parameter-free statistical rank correlation measurement for determining a cost space for predefined disparity levels in relation to at least one of the at least two input images (A1, A2); carrying out a correspondence analysis (D) for each point in the cost space for the predefined disparity levels, wherein the disparity to be determined in each case corresponds to the lowest costs; and determining the disparity graph from the previously determined disparities.
