Problems solved by technology

Because the lighting brightness of the car lights is limited, and the driver's vision is also limited, resulting in a short visual distance
And when encountering the sudden strong light on the opposite side, there will be a blind spot, and you will be at a loss because you can't see the road conditions clearly
In addition, in bad weather conditions such as rain, snow, fog, etc., the viewing distance is closer, and the vision is blurred and easily fatigued.
All of the above situations make the driver nervous and prone to dangerous situations or traffic accidents

Abstract

The vehicular auxiliary night vision device includes front photosensitive video camera to take the image before the vehicle; band-pass filter in front of the lens of the front photosensitive video camera; infrared ray projector(s) installed in the front part of the vehicle; and the monitoring display to display the image before and after the vehicle. The power cords to the infrared ray projector(s), the front photosensitive video camera and the monitoring display are connected via control switch to the key switch of the vehicle, and the video output of the front photosensitive video camera is connected to the input of the monitoring display.

Description

technical field [0001] The invention relates to a motor vehicle night vision device. More specifically, it relates to a night vision device for motor vehicles that uses near-infrared imaging principles to facilitate drivers to observe road conditions. Background technique [0002] At present, when a motor vehicle is running at night, it is mainly illuminated by a near light or a high beam. Among them, the effective irradiation distance of the low beam is about 40m, and the effective irradiation distance of the high beam is about 100m, and the reflection distance from human eyes observing the road conditions to taking measures is about 70m. Because the illumination brightness of car lights is limited, and the driver's vision is also limited, resulting in a short viewing distance. And when encountering the sudden strong light on the opposite side, there will be a blind spot, and you will be at a loss because you can't see the road conditions clearly. In addition, in bad wea...
