CLASSIFICATION TECHNIQUE FOR ASSESSING A VISIBILITY DEGRADATION IN IMAGE DATA UNITS

摘要

The present invention concerns a classification technique for evaluating a visibility degradation in image data units (Pi). Image data units (P1, P2, P3, P4) concerning the environment (3) of a vehicle (1, 1') are gathered from a vision sensor (2, 2'). At least a share of the image data units (P1, P2, P3, P4) contains image information which is subject to a visibility degradation based on at least one vision degrading influence (5, 6, 7, 8). The invention suggests various methods and devices for automatically creating filter rules based on an artificial intelligence approach and provides a classification device (4) that can estimate a visibility degradation of newly gathered image data units (P*) by attributing a rank parameter (R*), thereby allowing to judge the reliability of vision sensor data.
