license plate recognition system < / a > precautions for purchase

I. stability of license plate recognition system

With the improvement of the product algorithm of license plate recognition system and the technology of operators, integration has long been an important topic. At this stage, the most important thing to pay attention to is "stability". The definition of stability is: within a given speed range, the accuracy to be achieved will not produce excessive error due to the influence of external environment

II. Measured recognition rate of the system

Almost everyone claims to have a high recognition rate, but in order to avoid shifting the responsibility for poor operation due to the difference in product cognition between the two sides, users may wish to require field testing when purchasing the license plate recognition system, and the testing time should exceed two weeks as far as possible, so as to judge whether the recognition result is "exaggerated". It is possible to know the environmental impact of the field for only a few hours or even two a week, because the system can not recognize the situation in a field

III. software and hardware architecture

In addition to the above two points, since license plate recognition is a "system", the quality of software and hardware architecture will certainly affect the "presented results". As for what kind of software and hardware is suitable for what kind of environment, it depends on the environment, because different application environments may not have the same requirements for recognition rate, which depends on experience accumulation
