1. noun night vision system to explain
is a night vision system for military purposes from car driver assistance systems. With the help of this support system, the driver’s ability to anticipate higher in the process of driving at night or in low light, it can provide a more comprehensive and accurate information to the driver to potential danger or issue an early warning.
2. Characteristics of night vision system
night vision systems allow the operator to identify the test dummy dressed in light clothing street a distance of about 210 meters, about 41 meters earlier than the xenon headlights. In a pedestrian dressed in black, it may be about 92 meters ahead. This means that the use of night vision assist system can be night driving safety by 125% or more. At the same time, due to take full advantage of the potential hazard information also enables the driver to psychological pressure during the night while driving greatly alleviated, and thus make the process more comfortable and relaxed driving.
In the night vision system can be a potentially dangerous situation night lights outside the irradiation range is displayed on the windshield, so that the wide field of vision of drivers to avoid traffic accidents . Night vision system can help the driver see the situation in front of the car will glare at night.
night vision systems can not replace the lamp, it is only an auxiliary device. As the night vision system is expensive in the United States only as an option of luxury cars sold.
The new developments can provide greater field of view, and will not let the reverse of the vehicle was dazzling. As a result of Night View Assist system, you can see the traffic signs in advance not shine lights the darkness of the past, corners, pedestrian, car, missing goods or other things can be dangerous on the road. In this way, the driver can brake in time or take avoiding action. In addition, this system can reduce the driver at night driving stress and fatigue, see beauty, which can react quickly and correctly in a pinch.
equipped with a night vision system for a vehicle equipped with the auxiliary two additional infrared headlamp can shine a distance of approximately 200m in front.
Since the auxiliary headlamp night vision systems operate outside the visible wavelength range, and therefore does not affect human sight. In the inside of the windshield, an infrared camera can record a small front of the vehicle environment, driving and display it inDisplay on the instrument panel driving cabin.
When the vehicle speed exceeds 15km per hour, the driver can start the night vision assist system. The headlamp open, then simply pressing a button on the dashboard, the display shows the speed of 8 inches usually camera image is switched to a state. Road conditions ahead of the vehicle with a clear grayscale images appear in front of people.
3. The night vision system works
Principle
It is a night vision system invisible infrared converted into visible light. 0 degrees above absolute object must radiate energy. The lower the temperature, the longer the wavelength. When the temperature is generally as infrared. When the temperature is about 800 degrees, radiation to visible light, a red-hot iron is why one can see the light. Infrared is invisible, at night there is no visible light, but infrared radiation is still, at different temperatures and the surrounding trees, the radiation of infrared wavelengths are also different. Because infrared radiation is very weak, it is converted into visible light is weak.
