1. A method for analyzing a target in a stereo image by displaying the stereo image using a cascade structure, the method comprising: generating a plurality of first-level structure maps based on the stereo image, each first-level structure map being based on an individual tolerance level of a first relevant feature, rule or model of the stereo image, each first-level structure map of the plurality of first-level structure maps including a representation of the target divided according to an individual first division level such that the first-level structure maps include separate, respective first representations of the target divided according to separate, respective first division levels; and at least partly integrating the plurality of first-level structure maps to generate a structure map of a first-level target analysis result including a representation of the target, wherein the at least partly integrating includes performing mutual correction of the plurality of first-level structure maps to determine a division level, of the first division levels, that is associated with a representation of the target, of the representations of the target, having a greatest level of accuracy based on a feature of the target, to generate a structure map of the first-level target analysis result that includes a representation of the target divided according to the determined first division level.
