Abstract
The invention concerns a process and a device, which make it possible to reliably, with the least amount of computing power, recognize traffic signs and to display these as memory aids for an observer. Image data of an image sensor are analyzed and classified in an information processing unit, and on the basis of the results classification image segments and/or symbolic image representing data stored in a memory unit are recorded in a memory unit and are displayed by means of a display unit. In the further processing of the image data, extracted objects are separated and classified into traffic sign specific upper classes and lower classes. Subsequently, a synthetic image of a traffic sign is generated, stored in a memory unit, and displayed by means of a display unit.
