1、车牌识别系统的稳定性能:

　　随着车牌识别系统产品算法与业者的技术提升，畅荧智能小编认为，整合早就不是重要的话题，现阶段最需要注意的重点反而是“稳定度”。稳定度的定义是：在一个既定的车速范围内，不会让必须达到的准确度，因外在环境影响而产生过大的误差。

1. Stable performance of license plate recognition system:

With the improvement of license plate recognition system product algorithm and industry technology, Chang Ying smart Xiaobian believes that integration has long been not an important topic, but the most important focus at the present stage is "stability". The definition of stability is: in a given speed range, will not let the accuracy that must be achieved, due to the influence of external environment caused by excessive error.

　　2、软硬件架构:

　　车牌识别系统除了以上两点外，车牌辨识既然是“系统”，当中软硬件架构的好坏，当然会影响“呈现的结果”。至于什么样的软件跟硬件，适合什么样的环境，这就必须因环境而异，因为不同的应用环境，对于辨识率的要求未必相同，而这就必须靠经验累积。

2. Hardware and Software architecture:

License plate recognition system in addition to the above two points, license plate recognition is a "system", in which the software and hardware architecture is good or bad, of course, will affect the "presented results". As for what kind of software and hardware is suitable for what kind of environment, it must be different from environment to environment, because different application environment, the requirements for recognition rate may not be the same, and this must rely on experience accumulation.

　　3、系统实测识别率:

　　几乎每家都宣称拥有高辨识率，但为了避免事后因为双方对产品认知有差异，而将运作不良的责任互相推托，用户在采购车牌辨识系统时，不妨要求实地测试，而且测试时间最好超过两个礼拜，比较能判断辨识结果是否“言过其实”。因为系统现场是一个多变的环境，两个礼拜应该可以对于场域可能影响辨识率的情形，大约掌握了八成，如果只是测一天、甚至几个小时，是无法了解的。

3. System measured recognition rate:

Almost every claim to have a high recognition rate, but in order to avoid later because of the two sides of the product cognition difference, and the poor operation of the responsibility of each other, the user in the purchase of license plate recognition system, may wish to request field testing, and the test time is better than two weeks, can judge whether the identification results "exaggerated". Because the system site is a changeable environment, two weeks should be able to master about 80% of the situation that the field may affect the identification rate. If it is only measured for a day or even a few hours, it is impossible to understand.
