How to make your license plate recognition system more stable
Today's parking lot or community and the gates of a large number of enterprises and institutions are using the entrance and exit system to manage them. Advanced equipment can certainly make your site more beautiful, and the intelligent era is coming. It needs to be more intelligent. The high-tech products installed on the back of advanced products can not be separated from the actual use of technical issues, first on the current license plate recognition system to do a simple technical description.
The license plate recognition technology is now more popular, and the 2nd and 3rd tier cities are also constantly being replaced. The advanced equipment must pay attention to the following issues:
1. The license plate recognition is based on the license plate of each vehicle. Vehicles can be identified and accessed as long as there are license plates. The current domestic identification technology is very mature. Even though the recognition rate is still 99.6%, there are still some vehicles. Will block in the door, how to solve this problem will be the industry is facing practical problems, but fortunately, the emergence of WeChat technology to solve this problem is to set up two-dimensional code at each entrance, when the vehicle does not have a license plate or can not identify Select the QR code to scan out the entrance.
2. The position of the camera gun is another technical problem for license plate recognition. When installing the camera gun, the technician will debug the camera gun. Here is a technical approach. First of all, adjust the shooting position of the camera gun. The second is to To adjust the shooting area inside the camera gun, the general situation to wait for the direction of the vehicle to enter and exit the front, start the camera gun shooting, this will obviously increase the recognition rate of the camera gun. Finally fixed the camera gun, can not easily shake, which will affect the normal identification status.
3, the role of fill light is very obvious, the general fill light will choose to automatically open at night, when the night falls, fill light automatically open, some current camera gun comes with fill light function, but the actual application seems to be not the effect Very good, the main reason is that the direct light to the license plate on the fill light is easy to cause exposure when shooting, a direct impact on the vehicle access, in fact fill light is only an auxiliary measure, the general commissioning light can not be directly on the license plate Instead, the light is reflected on the ground through the fill light, and the extra light of the fill light is reflected on the license plate. When the camera gun captures the license plate, the camera will be very clear and the license plate exposure phenomenon will not occur. This kind of practical application has greatly improved. License plate recognition recognition rate.
4. The improvement of export payment can truly reflect the role of license plate recognition. The use of license plate recognition is more and more widely used. Vehicles pass through the entrance and exit quickly, but because the exit requires some vehicles to pay, they can leave. This will also affect the vehicle's access speed. When the license plate recognition system is used, it can quickly charge. In order to make the license plate recognition system play its role, the current method of QR code scanning and payment will greatly assist the license plate recognition system to improve the time and efficiency of access. In the future, all license plate recognition systems will use the QR code payment mode to receive everyone. Welcome. This system can truly reflect the advantages of license plate recognition.
5, A drive into the district, B drive can leave the district, which is the license plate recognition in the use of the problem. When the card is swiped into the system, when the vehicle enters the community, the owner only needs to take the card away from the vehicle, and the natural vehicle parked in the community is safe. If there is no card, the vehicle cannot enter or exit the community. Therefore, the loss of the vehicle in the community rarely occurs. Every time the owner returns to the community, he will consciously bring the card home, so as to avoid losing the vehicle in the community. However, under the current situation of license plate recognition, how can we ensure that vehicles cannot be lost when they are in the community? In the future, face recognition technology will be added on this basis, so that the future license plate recognition system + face recognition technology can make the license plate recognition mode more perfect. The lock car function of Guangzhou Kema Technology Co., Ltd. can also be used to control the vehicle. As long as the owner drives the vehicle into the community, click on the lock car function on the Happy Housekeeper APP, so that the vehicle is locked into the community by the system. No one can This car out of the district, only the owner click on the unlock feature, the vehicle can normally enter and leave the community, so that parked in the community of vehicles more secure and reliable.
Technology will set up a difficult road. Only when these difficulties can be solved can the license plate recognition system be further improved. With the changes of the times, there will be an endless stream of new generations of products. How to allow users to have a better experience during the experience will be Make some backward products eliminated. Koma Guangzhou will provide you with high quality products.
