通常,从技术上评价一个车牌自动识别系统从识别率、识别速度和后台管理三方面做综合评判,当然,一切都以系统正常稳定运营为前提。
Generally, a license plate recognition system is evaluated from the three aspects of recognition rate, recognition speed and background management, and of course, everything is based on the normal and stable operation of the system.
其中最重要的指标是识别率,而识别速度则决定了一个车牌识别系统是否能偶满足实时实际应用需求;后台管理体系则决定着这个车牌识别系统是否好用,还应注意考虑客观因素的存在,比如车牌污损模糊、遮挡掩盖、天气情况等等意外。
One of the most important indicator is the recognition rate and recognition speed, determines whether a license plate recognition system can even meet the real-time application requirements; the backstage management system determines the license plate recognition system is easy to use, should also pay attention to consider the existence of objective factors, such as car brand, defaced fuzzy masking, weather conditions and so on occlusion accident.
但是稳定的后台需具备以下几点要素:首先要有稳定存储识别结果和图像数据的功能,以防出现网络差错数据会丢失不方便时候人工排查;有效的自动对比和查询技术,要求被识别的牌照号码要从数据库中的车牌码自动对比或者提示报警及时;还要提供实时通信、网络安全和远程维护,以便数据动态及时交换,数据库能自动更新,硬件参数设置和系统故障诊断。
But the stable background need to have the following elements: first of all have stable recognition results and image data storage function, to prevent the emergence of network error data will be lost is not convenient when artificial; effective automatic comparison and query technology requirements identified the license number license from the database code automatic alarm or contrast in a timely manner; to provide real-time communication, network security and remote maintenance, so that the dynamic data exchange in a timely manner, the database can be automatically updated, parameter setting and fault diagnosis hardware system.
同时,车牌自动识别技术的提升也需要广大用户支持产品,能将使用问题及时反馈给设计公司,以便做出更好改进。
