The invention discloses a false license plate recognition method based on an image processing technology, and the method comprises the following steps: S1, collecting vehicle image data, and obtaining license plate information data and vehicle type information data of the vehicle image data; s2, creating a new vehicle information database table, and importing the license plate information data and the vehicle model information data into the new database table by using an SQL (Structured Query Language) statement; s3, using an SQL statement to import license plate information data and vehicle type information data in the existing vehicle information database into the newly-built vehicle information database table; and S4, constructing a minimum perfect hash function comparison model, and comparing the license plate information data and the vehicle type information data in the new vehicle information database table by using an SQL (Structured Query Language) statement. According to the method, the minimum perfect hash function comparison model is constructed, so that efficient comparison of the license plate information and the vehicle type information can be realized, the search time and space of a database are reduced, and the comparison efficiency and accuracy are improved.
本发明公开了一种基于图像处理技术的虚假车牌识别方法,该方法包括以下步骤:S1、采集车辆图像数据,得到车辆图像数据的车牌信息数据和车型信息数据;S2、创建新的车辆信息数据库表,使用SQL语句将车牌信息数据和车型信息数据导入新的数据库表中;S3、使用SQL语句将已有的车辆信息数据库中的车牌信息数据和车型信息数据导入到新建的车辆信息数据库表中;S4、构建最小完美哈希函数比对模型,使用SQL语句对新的车辆信息数据库表中的车牌信息数据和车型信息数据进行比对。本发明构建最小完美哈希函数比对模型可以实现高效的车牌信息和车型信息的比对,减少了数据库的搜索时间和空间,提高了比对的效率和准确性。
