Abstract:
A process for recognizing and displaying traffic signs, comprising:analyzing and classifying image data from an image sensor in an information processing unit, on the basis of the results of the classification, storing image segments and/or a symbolic image representing image data in a memory unit, and displaying this by means of a display unit, wherein in the framework of the analysis in the information processing unit it is determined whether the image data from the image sensor contains one or more objects which, with sufficient confidence, are traffic signs, and subsequently supplies these objects to a further processing and classification comprising: separating the image data of the objects, in the data processing, into traffic sign specific upper classes and lower classes, extracting, during the separation, appropriate class,specific characterizing data, supplying the class-specific characterizing data to separate classifications, replacing the class-specific characterizing data, if they have been correctly recognized with high confidence by the classification system, by appropriate image data representing the symbolic representation stored in a memory unit, or by the appropriate original image data originating from the image sensor, and synthesizing the image data resulting from this replacement into a synthetic image of a traffic sign, storing this image in the memory unit, and bringing it to display in the display unit.
