Problems solved by technology

[0003] Due to the complexity and diversity of road conditions, the brightness of different roads is not the same. When performing license plate recognition, it is often necessary to perform supplementary light operations on the recognition scenes where the light does not meet the requirements. The existing supplementary light for license plate recognition needs to be supplemented by manual switches. To achieve this, it is necessary to manually judge whether the supplementary light is needed, and then perform the connection and lighting operation of the supplementary light, and the supplementary light requires complicated wiring to realize the switch of the supplementary light, the operation is complicated, the operability is poor, and it cannot be automatically activated. Appropriate fill light according to road conditions

Abstract

The invention discloses an automatic light supplement method and system for number plate identification. The system comprises a light dependent resistor, a controller, a power supply chip, a light emitting diode (LED) supplement light and a power supply; the light dependent resistor is used for detecting environment luminance and transforming the detected environment luminance into a photosensitive voltage value; according to the photosensitive voltage value, the controller outputs a PMN signal to the power supply chip, and the power supply chip controls the light supplement luminance of the LED supplement light through the PMN signal; the LED supplement light adjusts the light supplement luminance through the control of the power supply chip, and light supplement is achieved; the power supply provides power for the system. According to the automatic light supplement method and system, the light supplement luminance can be automatically adjusted according to the environment luminance, and automatic intelligent light supplement is achieved.

Description

Technical field [0001] The invention relates to the technical field of license plate recognition, in particular to an automatic light supplement method and system for license plate recognition. Background technique [0002] With the development and progress of science and technology, it is more and more common to use cameras to monitor road conditions and vehicle condition information. During the monitoring process, the recognition of license plates is very important. License plate recognition is generally a pattern recognition technology that uses dynamic video or static images of the vehicle to automatically recognize the license plate number and license plate color. A complete license plate recognition system generally includes vehicle detection, image acquisition, license plate recognition, and so on. [0003] Due to the complexity and diversity of road conditions, the brightness of different roads is not the same. When performing license plate recognition, it is often necessar...
