Einrichtung zur Erfassung von Zeichen auf Objekten, insbesondere von Buchstaben und Ziffern auf Nummernschildern von Kraftfahrzeugen

摘要

Device for recognising characters, particularly letters and numbers on number plates of motor vehicles, in which a grey-scale image is analysed. First the characters to be recognised are separated out of the grey-scale image recorded by a video camera, and digitised and then converted in a character recognition process into digital characters, preferably coded in ASCII code, which can be easily processed further.
