The influence of gossip we license plate characteristics of license plate recognition rate

About parking system of license plate recognition technology difficulty, the last time we have been analyzed, this time we want to discuss is: foreign license plate recognition rate is high, the mature technology, and the introduction of license plate recognition and development of our country for several years, although has obtained the good results, but the overall effect is why there are gaps?This gap in addition algorithm, the characteristics of the license plate in China will also affect the recognition rate.1. Foreign car license plate, such as Europe and the United States, is generally composed of English letters and Arabic numerals, more easy to recognize, but our country is made up of Chinese characters, letters, Numbers, increased difficulties of identification.
2. Foreign license plate specification in both size and more uniform in the ordering of the characters, convenient video recognition.Due to the special national conditions in our country, different vehicle types provisions of the specifications of the different formats, such as military, government car, the police car, it will also affect the license plate recognition.
3. Foreign license plate color usually only license plate background and characters of two kinds of color, and color contrast is strong, easy to identify;License plate color has a variety of color composition in our country, such as blue black white plate, yellow bottom plate, and the license plate, etc., these will have an impact on license plate recognition.
4. Because of roads, the environment in our country, the license plate is vulnerable to pollution, can also on the road, it also brought difficult to identify.

after the above analysis we can see that in our country, the recognition rate is not only received the influence of the algorithm, some ideology also affected the recognition rate, how surprising conclusions.
