Abstract
A method in a training phase includes acquiring a first image of an environment of a means of locomotion from a first position, using an optical sensor; acquiring a second image of the environment of the means of locomotion from a second position, differing from the first position, using the optical sensor; ascertaining features that represent the first image and ascertaining features that represent the second image using an algorithm for feature extraction; selecting those features of the first and the second image which do not meet a predefined rating criterion; and ascertaining significant similarities between the selected features of the first and the second image and storing references that represent the significant similarities. A method is performed in an execution phase that makes use of the stored features of the training phase.
