The invention provides a license plate recognition, parking charging transaction and consensus method, and belongs to the technical field of license plate recognition. The invention relates to the technical field, in particular to a method comprising the steps that N vehicle pictures are collected according to a vehicle, and N is a positive integer and is larger than or equal to 2; identifying that the license plate number value in the ith vehicle picture is pi, wherein i ranges from 1 to N; the occurrence frequency j of the corresponding license plate number values pi in the N vehicle pictures is counted, the value of j ranges from 1 to N, and the number of the license plate number values pi is ranked according to the size; the license plate number value P with the highest occurrence frequency is calculated, the license plate number value P with the highest occurrence frequency serves as the license plate number of the vehicle, and P is one of pi. Aiming at the technical problem of low license plate recognition efficiency in the prior art, the license plate recognition accuracy can be improved, and convenience is brought to vehicle owners.

    本发明提供了一种车牌识别、停车计费交易和共识方法,属于车牌识别技术领域。本发明涉及技术领域,尤其涉及包括:根据一车辆被采集到的N张车辆图片,N为正整数,N≥2;识别出第i张车辆图片中的车牌号码值为pi,i取值为:1至N;统计N张车辆图片中对应的车牌号码值pi的出现次数j,j取值为:1至N,并进行大小排序;计算出现次数最高的车牌号码值P,将出现次数最高的车牌号码值P作为所述车辆的车牌号码,其中P为pi中的一个。针对现有车牌识别效率低的技术问题,它可以提高车牌识别准确率,为车主带来方便。
