号牌识别是智能交通系统实现的关键技术,在自动收费、车流监控、电子警察等方面有着广泛的应用。提高号牌识别率一直是非现场执法设备等智能交通系统的追求目标。本文从配色、字符、结构等号牌属性出发,根据号牌识别流程,分号牌属性对号牌识别结果进行了统计分析,根据分析结果对号牌生产与设计提供了建议。 Number plate identification is the key technology of intelligent transportation system, which has a wide range of applications in automatic charging, traffic monitoring, electronic police and so on. Increasing the number plate recognition rate has long been the pursuit of intelligent transportation systems such as off-site law enforcement equipment. Based on the attributes of number plate, such as color, characters and structure, this paper makes a statistical analysis on the identification results of number plate according to the identification plate identification process and the property of the number plate. According to the analysis results, suggestions are provided for the plate production and design.
