Electronic police anti-glare device and control method thereof

The invention relates to the technical field of intelligent traffic, in particular to an electronic police anti-glare device comprising a signal collecting and triggering module, a backlight detection module, a control module, a camera module, an intelligent light dimming and filling module and a power supply module. The power supply module supplies power for the other modules; the signal collection triggering module is used for collecting vehicle location information and illegal information and triggering signals; the backlight detection module implements the detection of backlight of the camera module and licence plate yin and yang situations resulted from the backlight; the camera module comprises an imaging unit, and licence plate algorithm software is set in the imaging unit; the control module controls the imaging unit exposure and the intelligent light dimming and filling module to flash and fill the light according to the triggering signals output by the signal collecting and triggering module and detection results of the backlight detection module. The invention further provides a control method of the device. Influence on image capture by various lights is avoided, the recognition rate of the licence plates is increased, energy is saved, and environment is protected.
