Infrared night vision system for use in the automotive industry
Driving at night, the road is clearly recognizable from the distance in front of your car illuminated by your high beams, but there are always dangers lurking in the dark glimpses ahead.
Despite the considerable advances in automotive lighting technology over the years, nighttime driving is still much riskier than daytime. It is often the case that when you spot someone changing a tire on the side of the road in the light, or a pedestrian or livestock crossing the highway, it is already too late to be caught off guard. General Motors has also conducted a questionnaire survey of drivers, for the car on the thirty or forty kinds of electronic devices, so that they are based on their own preferences of the degree of scoring, the results of the survey showed that the vast majority of drivers on the car night vision system, hope that their cars can be fitted with this equipment. The reason is because like ** airbags and ABS only in the car in case of emergency can play a role, and car night vision system belongs to the active ** equipment, can be prevented in advance, greatly improve the car in special weather driving ** sex.
According to the U.S. National Highway Traffic and Safety Administration (NHTSA) statistics, although night driving in the entire highway traffic accounted for only a quarter of the fatal accidents occurred but accounted for half. And night vision ** caused by the accident accounted for 70% (2002 data)
But if you have a car infrared night vision, then you are equal to grow a pay a telescope owl eyes, because the car's night vision system will help you see clearly selected in the front light illumination outside the scope of the front view, so you have foresight, can be found as early as possible to see the potential dangers in the black, thus improving the safety of the car too much.
On the screen, the edge of the highway, the middle of the road markings, objects on the highway, as well as pedestrians on the side of the road ready to cross the highway can be displayed. As a result, automotive night vision is able to spot more than headlights and can take in everything up to twice the distance of high beams. But the nature of this infrared imaging technology is such that the picture you see looks like a black and white TV image. However, the lack of image quality in automotive night vision is more than compensated for in the field of view.
The biggest beneficiaries of night vision systems will be those nighttime automobile drivers, who can have more leeway to brake and react due to the greatly expanded safety distance. An automotive night vision system is not a substitute for visual information obtained with your eyes; it simply provides you with information about road conditions farther away when it's dark, especially to help when you can't see clearly. Although automotive night vision devices can provide visual images more than 50 times that of the human eye at night, we are strongly opposed to the use of ordinary automotive night vision devices as an airplane blind landing system. Automotive night vision devices simply extend the driver's field of vision beyond the range of headlight illumination. Therefore, before using automobile night vision devices, you must comply with national traffic laws and turn on the headlights, otherwise it will not be safe.
Night vision for police and military systems requires the purchase of specialized night vision equipment.
