Abstract
In a method for detecting and tracking objects by stereo image evaluation a part of structure class images is initially generated from a recorded stereo image pair. Differences in brightness of selected pixels in the environment are determined for each pixel as digital values, which are combined to form a digital value group, with identical groups defining their own structure classes. Structure classes which lack a brightness change along the epipolar line are discarded. Corresponding disparity values are then determined for the pixels in the other structure classes and are collected in a disparity histogram with a given frequency increment. The pixel group that belongs to a given grouping point area of the histogram is then interpreted as an object to be detected.
