Abstract

In a method for determining a depth map from stereo images, the disparity for a pixel is determined from a discrete quantity of predefined disparity values that are distributed over the entire predefined disparity value range. The distribution has at least two different distances between different pairs of adjacent disparity values. In this method, it is possible that only those disparities for which a more precise determination is required, will be more precisely calculated.
