Smart bayonet anti-glare device and control method thereof

Abstract

The invention belongs to the technical field of road traffic smart checkpoints, and in particular relates to an anti-glare device for a smart checkpoint, including a backlight detection module, a vehicle distance detection module, an automatic dimming and supplementary light module, a control module, a camera module, a trigger module and a power supply module; The module includes an imaging unit, in which the license plate algorithm software is embedded; the backlight detection module, the vehicle distance detection module, and the trigger module collect corresponding information and output it to the control module, and the control module controls the start and stop of the vehicle distance detection module according to the received information. The brightness of the light-emitting unit of the electric light source and the exposure amount of the imaging unit in the dimming supplementary light module also disclose a control method of the device. Through the collection and processing of specified information, the phenomenon of backlight and glare is effectively eliminated, and the whole process is automatically processed, which is convenient, fast and accurate, and effectively solves the problems and hidden dangers caused by backlight and glare.

Description

technical field

[0001] The invention belongs to the technical field of road traffic smart checkpoints, and in particular relates to an anti-glare device for a smart checkpoint and a control method thereof. Background technique

[0002] In the actual application of the existing smart bayonet, the phenomenon of backlight and glare interference is very serious. The incentives come from two aspects. One is the backlight interference caused by sunlight, car lights and other ambient light directly hitting the capture camera, and the other is When the supplementary light flashes during the capture, it will cause glare interference to pedestrians, drivers and passengers. When the backlight phenomenon occurs, halos and spots are formed on the license plate picture captured by the camera, so that the image is not clear, the license plate cannot be recognized, and it also affects the service life of the camera; when the glare phenomenon occurs, it will cause pedestrians and drivers.
