The invention relates to a character similarity calculation method for radio frequency identification and license plate identification data fusion. The method comprises the following steps: a character identification error counting step of accumulating the number of characters wrongly identified as other characters in a license plate by license plate identification; a character recognition error statistics step of calculating statistics such as a mean value and a variance according to the character error count of license plate recognition; and a character similarity calculation step of calculating the similarity of the characters according to the same dosage of the character recognition errors of the license plate recognition. The calculated character similarity can accord with the actualsituation, the result of radio frequency identification and license plate identification data fusion is fully explained, a basis is provided for improving license plate identification, and the methodplays an important role in automobile electronic identification application in the field of intelligent transportation.

    本发明涉及一种用于射频识别和车牌识别数据融合的字符相似度计算方法,包括:字符识别错误计数步骤:累计车牌识别将号牌中一个字符错误识别为其它字符的数目;字符识别错误统计步骤:根据车牌识别的字符错误计数,计算均值和方差等统计量;字符相似度计算步骤:根据车牌识别的字符识别错误同剂量,计算字符的相似度。本发明计算出的字符相似度能够与实际情况相符合,充分解释射频识别和车牌识别数据融合的结果,为改进车牌识别提供依据,在智能交通领域汽车电子标识应用中,将发挥重要作用。
