A Car Licence Plate Reader (CLPR) using fuzzy inference and neural network algorithm has been developed in Industrial Technology Research Institute (ITRI) and installed in highway toll stations to identify stolen cars. It averagely takes 0.7 second to recognize a car licence plate by using a PC with 80486-50 CPU. The recognition rate of the system is about 97 %. The techniques of CLPR include vehicles sensing, image grab control, optic pre-processing, lighting and Optic Character Recognition (OCR). The CPLR can be used in vehicle flow statistics, the checking of stolen vehicles, automatic charging systems in parking lots or garage management and so on.
