Problems solved by technology

[0003] However, the existing technology has the following defects: when the license plate is defaced, blurred, blocked, or the weather is bad (snow, hail, fog, etc.), the recognition rate will be lower or cannot be recognized. The system has no processing mechanism, so the correct recognition rate is not high

Embodiment Construction

[0046] like figure 1 Shown is the flow chart of Embodiment 1 of the license plate recognition method of the present invention, the license plate recognition method includes:

[0047] A. When a vehicle is detected passing by the scene, the video image of the license plate of the vehicle is collected. In this step, the scene can be detected by one or more devices among buried coils, infrared detectors, radars, and cameras. Is there a vehicle passing by. In addition, the video image of the vehicle can be collected through DVR and camera;

[0048] B. Process the collected video image, and judge whether the license plate number can be automatically recognized from the processed video image, if not, then perform step C; if so, then perform step E, in this step, need to explain The most important thing is that when the video image of the license plate is collected, the automatic recognition of the system is given priority to identify the license plate number to save time. However,...

Abstract

The invention discloses a vehicle license plate recognition method and system. The vehicle license plate recognition method comprises the steps that A, when the situation that a vehicle passes on the site is detected, a video image of a license plate of the vehicle is acquired; B, the acquired video image is processed, whether a license plate number can be automatically recognized through the processed video image or not is judged, if not, the step C is executed, and if yes, the step E is executed; C, the acquired video image is sent to an operating terminal; D, the received video image is displayed by the operating terminal, and a license plate number input by an operator according to the displayed video image is received; E, the license plate number is recorded and stored. The invention further provides the vehicle license plate recognition system. By the implementation of the technical scheme, the vehicle license plate recognition method and system increase the correct recognition rate of the license plate numbers and are more reasonable in practical application.

Description

technical field [0001] The invention relates to the technical field of image recognition, in particular to a license plate recognition method and system. Background technique [0002] The vehicle license plate number is the unique "identity" of the vehicle, and the automatic license plate recognition technology can realize the automatic registration and verification of the vehicle's "identity" without any modification of the vehicle. Vehicle License Plate Recognition (VLPR) refers to a technology that can detect vehicles on the monitored road and automatically extract vehicle license plate information (including Chinese characters, English letters, Arabic numerals and license plate colors) for processing. License plate recognition is one of the important components of modern intelligent transportation systems, and it is widely used. Based on digital image processing, pattern recognition, computer vision and other technologies, it analyzes the vehicle images or video sequenc...
