1. A method for detecting road users and obstacles as a function of camera images so as to determine their distance from an observer and to classify them, comprising the steps of: identifying regions within a two-dimensional camera image that is not resolved with respect to distance using a classifier designed for detecting road users and obstacles; marking and ranging, in a subsequent step, the identified regions using a distance-measuring sensor with respect to their distance from the observer; and subsequently type classifying the identified regions using a type classifier.
