License plate identification control system and identification control method thereof

Abstract

The invention provides a license plate identification control system. The license plate identification control system comprises a license plate identification device, a control device and a blocking device. The license plate identification device identifies license plate information which is connected to the control device. The control device controls motions of the blocking device according to the license plate information. The invention also provides a vehicle identification control method. The vehicle identification control method comprises following steps of: (A) carrying out light supplementation to shoot image information; (B) snapshootting a target image; (C) analyzing the target image; and (D) controlling vehicles to pass according to the analysis result.

Description

technical field [0001] The present invention relates to a recognition system and method thereof, and further relates to a license plate recognition system and a recognition control method thereof, which can reliably and stably control vehicle traffic through accurate recognition of vehicle information. Background technique [0002] In modern life, the number of cars is increasing day by day. Cars bring great convenience to people's lives, but also raise new questions, how to better manage vehicles. [0003] Almost in every corner of our lives, there are different parking management channels. For example, if you drive into a certain area, you need to pass through the barrier before you can enter. Therefore, managing the entry and exit channels of vehicles is the first step in vehicle management. [0004] Generally speaking, during the process of vehicle entry and exit, detection and identification must be carried out first to detect whether there is a vehicle entering or lea...

AI Technical Summary

Problems solved by technology

In the existing identification method, the license plate information is usually observed and recorded by the on-duty personnel. In this method, the usual problems are that the timing is not accurate, errors often occur, and the amount of payment is determined by the on-duty personnel.

However, the existing license plate recognition device also has some defects. In some special cases, there is also the problem of inaccurate recognition.

Faced with some harsh environments, such as when the license plate is blocked, the paint on the license plate is blurred, strong light, backlighting, rainy days, foggy days, etc., the recognition is inaccurate or the accuracy rate drops

[0008] On the other hand, the license plate recognition process first needs to take images. Light is an important factor affecting image clarity during the shooting process. However, in the existing image acquisition process of license plate recognition, most of them do not provide auxiliary light sources. For the adjustment of light Less, or, can't change the light to improve clarity

[0009] In addition, the traditional license plate recognition device uses photoresistors to supplement light. Since the working process of photoresistor elements is greatly affected by external environmental factors, there is great instability, so the process of supplementary light is unstable.

[0010] Usually, a blocking device is controlled by the license plate recognition result, therefore, when the license plate recognition is inaccurate or unstable, the control of the blocking device is inaccurate, thereby causing time delay or damage to the vehicle due to inaccurate recognition, reducing the Improve the efficiency of vehicle identification control
