Intelligent night-vision control method and system

Abstract

The invention provides an intelligent night-vision control method and further provides an intelligent night-vision control system. The intelligent night-vision control method comprises the steps thatnight-vision control signals are received, wherein the night-vision control signals comprise the night-vision switch turning-on signal, the dipped headlight turning-on signal or a high beam turning-onsignal; an infrared lamp is lighted on in response to the received the night-vision control signals, and a front image of a vehicle is collected; the collected front image of the vehicle is processedto obtain an analog video with a preset visual range; and the analog video is output and displayed. Real-time screen image displaying can be provided for a driver and is equivalent to the visual effect when a high beam is turned on, but other drivers cannot be hindered, the response time of the driver during driving under the harsh climates such as rain, snow, haze and night is increased, and theactive safety performance of the vehicle is improved.

Description

technical field [0001] The invention relates to an intelligent night vision control method and system, in particular to an intelligent night vision control method and system realized by using infrared lamps. Background technique [0002] According to statistics from the U.S. National Highway Traffic Safety Administration, driving at night only accounts for a quarter of the entire highway traffic, but 70% of traffic accidents occur at night. The irradiation range of the low beam of the headlights of ordinary cars is only 30 meters away, and all the places where the light does not directly irradiate, the driver is difficult to see clearly, or cannot see at all. Although the high beam can be improved, it can only be used in rare cases because it affects the sight of drivers in the opposite lane. Vehicle-mounted night vision systems are active safety devices that can greatly improve the safety of vehicles driving in special weather. However, the current development costs of veh...

AI Technical Summary

Problems solved by technology

The illumination range of the low beam headlights of ordinary automobiles is only 30 meters away, and all the places where the light does not directly irradiate, the driver can hardly see clearly, or cannot see at all

Although the high beam can be improved, it can only be used in rare cases because it affects the sight of drivers in the opposite lane

Vehicle-mounted night vision systems are active safety equipment, which can greatly improve the safety of vehicles driving in special weather. However, the development cost of current vehicle-mounted night vision systems is relatively high, and many users are unwilling to install vehicle-mounted night vision systems.

[0003] Therefore, how to design a high-performance, low-cost, and high-reliability active night vision system to solve driving safety problems when the field of vision is poor such as rain, snow, haze, and night has become an urgent issue to be solved.
