The improvement of license plate recognition technology is very convenient for parking lot managers and car owners, and it is essential to alleviate traffic congestion and intelligent vehicle management. For the owner, the intelligent license plate recognition system automatically captures the license plate information when driving into the parking lot and automatically authorizes the gate lift through the information transmission.
In particular, parking lots with heavy traffic flow can be accessed in the parking lot in just one second. However, some users believe that the recognition rate of the license plate recognition system should be 100%. In fact, due to various objective reasons, the recognition rate is difficult to reach 100%.
What are the reasons for restricting the recognition rate of intelligent ANPR systems?
In the practical application of the parking lot with the smart license plate recognition system installed, there are many reasons that restrict the system recognition rate:
1, The system cannot identify an unlicensed car.
2, In extreme weather conditions (storms, blizzards), the car's license plate is blocked. The glare from night car headlights can also have a major impact on the license plate recognition camera.
3, Motor vehicle lane separation is not standardized and car license plates are sometimes blocked by passing pedestrians.
4, The parking lot entrance and exit terrain restrictions, the installation of the smart license plate recognition system must be through the field site inspection combined with the actual needs of users, design a reasonable solution.
At present, there are more and more intelligent ANPR systems used in parking lots in various regions, including communities, units, commercial plazas, public security organs, schools, hospitals, hotels and other places. This kind of intelligent management equipment has begun to spread in our daily life and always guarantee people's parking safety.
