Abstract
A localization device for visually determining the location of a vehicle includes a camera unit for capturing image data and a control unit. The control unit is configured to recognize at least one landmark in the captured image data and to determine a quality value for each landmark. The determination of the quality value involves multiple recognitions of the particular landmark. In addition, multiple quality values for one landmark can be determined for different observation positions or observation directions. The control unit is further configured to adjust the quality value of a landmark already contained in a map, based on a new recognition by the localization device. The control unit is configured to determine the position of the localization device based on the recognized landmarks in conjunction with the map. The control unit is further configured to determine the position of landmarks in relation to a global coordinate system.
