Abstract: In car license plate recognition system, license plate location is the precondition of the whole recognition module. Now various methods are used in it, each of which has its own advantage. However, such problems as the quantity in calculation or the low correct location rate aren't solved. This paper uses mathematical morphology combined with its elemental calculation to realize the crucial procedure——license plate location in car license plate recognition. Experiment results show that such method can simplify the algorithm and has some correct location rate.
