METHOD FOR CALIBRATING AN EYE-TRACKING SYSTEM, METHOD FOR ANALYSING THE BEHAVIOUR OF A PERSON BY MEANS OF AN EYE-TRACKING SYSTEM, AND EYE-TRACKING SYSTEM AND MOTOR VEHICLE COMPRISING SUCH AN EYE-TRACKING SYSTEM

摘要

The invention relates primarily to a method for calibrating an eye-tracking system (10), in particular in a motor vehicle. It is proposed that the calibration according to the invention is performed in such a way that firstly the eyes (3) of a person (2) are detected by means of a camera system (12), the viewing direction (22) of the person is determined on the basis of optically detected features, and a viewing path (24) is determined, which reflects the temporal course of the viewing direction (22) and any change to it. Viewing path bundles (26) of frequently used individual sub-paths of the determined viewing path (24) are then determined on the basis of the determined viewing path (24) by means of clustering viewing path bundles (24). The determined viewing path bundles (26) are analysed and in particular compared with reference values, wherein correction parameters are derived on this basis which are used for the purpose of data standardisation in the event of a later analysis of further detected viewing directions (122) and/or viewing paths (124).
