| Abstract: | Vehicle license plate locating is of vital importance in automatic LPR(license plate recognition) system. With the license plate feature, first, image preprocessing is adopted , which is then followed by mathematical morphology operations. Next, a simple license plate searching algorithm is designed to get coarse location. In the end , an exact location is obtained according to the characteristics of character edge. The results of the experiment show that the algorithm possesses advantages of fast locating speed and high percentage accuracy. |
