Today I'm going to talk about the Alpr system, which is different from the ordinary parking lot management system. The Alpr system have a special alpr camera which equipt with multiple LED lights that can fill the light automatically when it is run in a very dark underground parking lots, parking lots with insufficient light, and so on, these places undoubtedly make it difficult for alpr system to recognize license plate correctly, so the Alpr cameras of the system are specially modified, with a variety of functions ,that is whyu the price of alpr camera is much higher than ordinary cameras.
IF you Do not know, now I will tell you in detail.Some Alpr system only need a all-in-one machine to complete the whole process of license plate recognition.
Of course,There is another type of Alpr system, which has a high-definition smart camera, a ground sensor coil, a smart channel gate and a high-definition display screen, all the parts work together to finish a complete license plate recognition process.
We know that the Alpr system may encounter all kinds of bad weather, such as typhoon, sun exposure, hail, snow and so on, so the quality of alpr system must be high enough to be unaffected by the bad weather.
The revamped Alpr system can work at high intensity 24 hours a day and can withstand high temperatures.The machine can be used normally unless encounter system failure,virus and other system problems.
In addition to resisting high temperature and cold, the main job of Alpr camera is to check vehicle number plates. If this operation cannot be carried out, no matter how good the other parts of alpr system is, it is useless.Engineer know that deeply, so all the Alpr system used by the engineer has a high pixel, which can achieve 98% accuracy in the case of insufficient light and incomplete license plate, just like the function of "divine eye", that is why the cost of Alpr system is so high.
The value of a product to an enterprise depends on whether the product can bring benefits to the enterprise. A high-quality Alpr system can have the same capacity as "divine eye", so it can reduce the error rate of license plate recognition can improve the enterprise's benefits.
In the process of license plate recognition, the part of image reading is very critical, which is the priority among all priorities of the whole recognition process.
So a lot of the changes have been made to Alpr system to ensure it works in a efficient way.For example, in the dark underground parking lot, Alpr system is difficult to collect images.At this time, light is needed to be made up, but it is impossible for someone to make up the light for Alpr camera 24 hours a day, so the alpr system must can make up the light automatically.Therefore, the Alpr system for license plate recognition is equipped with several LED incandescent lamps to prevent various emergencies that lead to low light.
Every day, there are a large number of vehicles pass the license plate recognition barrier, the large number makes most managers dizzy before,because they had to record the license plate by pen and paper.But in this special Alpr system, there is also an intelligent system that can convert the image information into electrical signals, which can not only be stored conveniently, but also transmit the signal to the license plate recognition parking lot system quickly.
The useful part of the image information should be selected and processed, and the license plate number information should be transmitted to the database to officially complete the identification workflow . Alpr camera system have all the functions which ordinary cameras have,and they have a better performance than the ordinary one.
In a word, the Alpr system is equipped with cameras with built-in intelligent algorithm, LED incandescent lamp, good effect of low illumination and high frame rate, etc., which is the special feature of the special Alpr system
