What Are the Reasons for the Low Recognition Effect of License Plate Recognition Camera in Parking L

Nowadays, most of the parking lots in the market adopt the license plate recognition system, and the license plate recognition parking lot has become a necessary demand for parking. However, when driving out of the parking lot, the owners of many communities will still encounter the situation that they drive in front of the road gate, but the license plate recognition camera does not recognize the license plate and have to return to re recognize it. Then, what are the reasons for the low recognition effect of parking license plate recognition camera? I. reasons for the parking lot gate system generally speaking, the system gives information, and the gate response is slow. It is necessary to consider whether the connection between the gate and the system is delayed. Second, the reason for the license plate recognition of its own products is to improve the recognition rate of the license plate.

First, the algorithm of the product must be powerful. Now the general parking lot cameras will have their own algorithm, but the license plate recognition camera will be affected under different environmental conditions, so the environment also has a great impact on the license plate recognition. III. reasons for the installation position of the license plate recognition camera in the parking lot. Attention should also be paid to the installation position of the license plate recognition camera. Generally, it is best to let the vehicle adjust the front of the vehicle before entering the recognition area, so as to shoot a high-definition license plate.

The horizontal angle of the camera should be kept between 15 degrees and 20 degrees, which is the most reasonable. The specific details need to adjust the angle of the license plate camera according to the on-site environment. IV. for reasons such as the buried position and distance of the ground induction coil, the distance between the ground induction coil and the road gate should not be too close. First, it is easy to hit the vehicle, second, it will affect the license plate recognition rate, and finally keep the distance at 2-3m. V. the reason for the speed of the vehicle is that the videos we usually see are actually composed of multiple pictures, which is also a well-known thing. The license plate recognition camera will select 16 frames from the continuously played pictures as the output picture, and then select different frames as the recognition picture.

So as to achieve the effect of video recognition; Therefore, there will be a situation. When the vehicle speed is too fast, it is easy to lose the frame and cannot be recognized. Therefore, we can see that the treatment method of most manufacturers is to add a deceleration belt. Vi. impact of weather and environment when the license plate recognition camera is used outdoors, too strong light will lead to the reflection of the license plate and reduce the recognition rate, while insufficient light at night will require supplementary light. In rainstorm, snow, storm and other weather, the recognition rate of most license plates will drop a little year-on-year.

For a parking lot system manufacturer, a good recognition rate is undoubtedly the basis for the success of an intelligent car parking system. Unlike other parking lot systems, the license plate recognition parking lot system is prone to failure to lift the bar of the gate or easy to be damaged due to the slow lifting speed if the recognition is wrong, unable to recognize or slow, This not only needs to be technologically advanced, but also overcomes some external factors.
