通常，從技術上評價一個車牌自動識別系統從識別率、識別速度和后臺管理三方面做綜合評判，當然，一切都以系統正常穩定運營為前提。
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.
其中最重要的指標是識別率，而識別速度則決定了一個車牌識別系統是否能偶滿足實時實際應用需求；后臺管理體系則決定著這個車牌識別系統是否好用，還應注意考慮客觀因素的存在，比如車牌污損模糊、遮擋掩蓋、天氣情況等等意外。
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.
但是穩定的后臺需具備以下幾點要素：首先要有穩定存儲識別結果和圖像數據的功能，以防出現網絡差錯數據會丟失不方便時候人工排查；有效的自動對比和查詢技術，要求被識別的牌照號碼要從數據庫中的車牌碼自動對比或者提示報警及時；還要提供實時通信、網絡安全和遠程維護，以便數據動態及時交換，數據庫能自動更新，硬件參數設置和系統故障診斷。
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.
同時，車牌自動識別技術的提升也需要廣大用戶支持產品，能將使用問題及時反饋給設計公司，以便做出更好改進。
