车载主动式红外线夜视仪系统Vehicle active infrared night vision equipment system

Driving at night time is small but the risk of a crash is great, because people's field of vision in the dark have been affected. But, don't worry, with the rapid development of automotive technology, will let the night into day, let your nighttime driving more easily.

Some car manufacturers are developing this let your nighttime driving becomes night vision system more relaxed, which BMW company after the study phase contrast and careful investigation, the BMW engineers choose infrared technology more innovative (FIR), is also the thermal cameras. To improve the safe use of imaging in the dark in a thermal imaging camera on. BMW believes that the efficiency of infrared technique for detecting pedestrians, animal, objects in the night and higher. Although the imaging display night vision instrument on the BMW is not clear, but by capturing the heat radiation body makes imaging shading highlight a very distinctive, dangerous and thus more easily identify

the front. In addition to the night, a good method of it is also against the fog.

The benefits of the driver BMW night vision system is when in non road when driving, through a narrow path, before entering the dark underground garage, significantly enhance the night driving comfort. Infrared technology using thermal cameras using human, animal, object sends the temperature, improves the image resolution. FIR intentionally did not show the full details of the traffic situation, avoid the main objects in front without your attention. In other words, be of no great importance details were removed, to avoid excessive distract the driver's attention. FIR in the control display dashboard central driver in image showing a high contrast image of the night. The driver simply viewing screen to obtain my goal, so the observation is like BMW night vision system is convenient to watch the rear-view mirror.

FIR allows the driver to see farther. As far as the covering range of the car in front of 300 meters. FIR can

see the distance is 2 times as far as the other system, the driver can earlier aware of hazards. In the 100km/h speed can be 5 seconds early find the target. FIR will not make you produce vertigo. FIR another characteristic is imaging the other approaching vehicle headlights, street lamp, traffic signal lamp, traffic sign of strong reflection etc. will make you have dizziness, installed between the FIR vehicles will not mutually interfere. Beyond the point of FIR technology, BMW still further function: it increases as the speed increases, the image on the road can also through the lens focal length change makes the long-range goal is amplified, make the target more clear.

Today, the new system is still not perfect, in the development of it BMW also took into account the driver eye observation vision, experiments show that combined with the real and the real image will cause the driver to feel impatient, it might not be the best solution. In addition, the camera BMW night vision system mounted on the front bumper of this position will be influenced by external factors, such as the road muddy, rain, easy to get
