What Is the Charm of the Popular License Plate Recognition Parking Lot System - Tiger Wong Technolog

With the rapid development of the Internet, the parking lot system is gradually updating from generation to generation. The traditional parking lot system architecture has long been thrown out of the sky. The current intelligent parking lot system can not meet people's living needs. With the application of license plate recognition technology to the parking lot system, the parking problem has been greatly improved, Compared with other card swiping or Bluetooth remote card reading parking lot systems, it has different charm, which is also the reason why it is very popular. Let's take a look at the charm of the popular license plate recognition parking lot system.

Charm 1. It can be recognized from a large angle in the parking lot. Compared with the electronic police and other scenes, the recognition from a large angle is the biggest difference between the parking lot and other scenes, and it is also the biggest bottleneck of the license plate recognition technology in the parking lot environment. It is difficult for the license plate recognition system to capture the rectangular license plate in the conventional proportion under the large angle of the parking lot. The license plate imaging deformation caused by the large angle is one of the recognized technical difficulties of license plate recognition. The difficulties are as follows: 1. Difficult license plate location: due to the angle taken by the license plate recognition camera, the license plate image is often not rectangular, Therefore, affine deformation must be made first to correct it into a rectangular image.

Therefore, it is not easy to extract license plates from such a complex external environment. 2. Image correction is more difficult: image correction uses directional high pass filtering (directional differentiation) to determine the direction of motion blur. Then the fuzzy scale is calculated by using the correlation principle. Charm 2. The recognition speed is quite fast. For the license plate recognition camera, the farther it is, the smaller the pixel is, and the closer it is, the larger the pixel is. Compared with other scenes, the lane of the parking lot is shorter, and the recognition of the current license plate recognition system is real-time.

It is a typical contradiction to support the recognition of license plates with large pixel width while ensuring the recognition speed. Generally, if the license plate pixel width is too large, the recognition speed must be slow. If the recognition speed is fast, the license plate pixel width is required to be within a certain range. Charm III. The matching rate of vehicles at the entrance and exit of the parking lot is quite high. The architecture and internal recognition algorithm of the license plate recognition system are also constantly improved and improved.

It is particularly noteworthy that some technologies extended and developed based on the hardware platform of license plate recognition, such as video speed measurement, vehicle type recognition, vehicle local feature recognition and comparison equivalence technology cooperate with license plate recognition to achieve the best vehicle matching rate at the entrance and exit of the parking lot, which is also a feature only available in the parking lot environment. Charm IV. parking charges are more strict. For the artificial cash charging method, on the one hand, it has high labor intensity and low efficiency. Another main disadvantage is that it causes great loopholes and cash loss in finance. Using the license plate recognition car parking management system, the system has a client and a management end.

The management end can provide rich report statistics functions. The fees charged by the toll collector per shift need to match the fees displayed by the system, so as to eliminate cheating and protect the interests of the parking lot manager. Charm v. blacklist and white list functions can be added. A major feature of the community parking lot is that the vehicles in and out every day are basically fixed. Therefore, for this part of vehicles, the white list function of the license plate recognition system can be used.

After importing the white list in the license plate recognition system, the vehicles in the white list function list can be automatically opened and released. You can also add a blacklist to the vehicles you don't want to put in. License plate recognition system was first applied in intelligent transportation, mainly used to detect vehicle violations on the road. Now this technology is applied to the parking lot system, which not only improves the management efficiency of the parking lot, but also improves the intelligent level. Although the recognition technology can not be 100% recognized, it can also reach more than 98%, It has obvious advantages over the parking lot without license plate recognition before.

It is believed that it will not be difficult to realize 100% recognition in the near future. Tigerwong parking equipment supplier has focused on parking equipment for many years! If you have any questions about the parking system, welcome to consult and communicate.
