Gadgets with infrared night vision used in the automotive industry
When driving at night, the road conditions are clearly identifiable within the distance in front of the car illuminated by the high beam, but there are always dangers lurking in the darkness ahead.
Despite advances in automotive lighting technology over the years, driving at night is still much more risky than during the day. It often happens that when you see someone changing tires on the side of the road, or pedestrians or animals crossing the road in the light, you are too late to meet and be caught off guard. General Motors has also conducted a questionnaire survey on drivers, asking them to rate the 30 or 40 electronic devices on the car according to their own preferences. The results of the survey show that most drivers have feelings for the car night vision system. A soft spot, wish they had it in their car. The reason is that airbags and ABS can only work in emergency situations in the car, while the car night vision system is an active device, which can prevent problems before they happen, and greatly improve the safety of cars driving in special weather.
According to the statistics of the U.S. National Highway Traffic Safety Administration (NHTSA), although driving at night only accounts for a quarter of the entire highway traffic, the fatal accidents that take place account for half. The accidents caused by night vision accounted for 70% (data in 2002)
But if you have a car infrared night vision device, then you have a pair of owl eyes wearing a telescope, because the night vision system on the car will help you see clearly the scene ahead that is outside the range of the headlights. So you have the foresight to discover the potential dangers in black eyes early, which greatly improves driving safety.
On the screen, the edge of the road, markings in the middle of the road, objects on the road and pedestrians preparing to cross the road can all be displayed. Therefore, the car night vision device can find more things than the headlights, and can have a panoramic view of everything within twice the distance of the high beam. But the nature of this "infrared imaging technology" determines that what you see is like a black and white TV image. However, the lack of image quality of the car night vision device gives more compensation in the field of view.
The biggest beneficiaries of night vision systems will be those driving cars at night, because the safety distance is greatly expanded, they can have greater braking and reaction leeway. The car night vision system cannot replace the visual information obtained by the eyes. It only provides you with further road condition information when it is dark, especially when you cannot see clearly. Although car night vision devices can provide 50 times more visual images than human eyes at night, we firmly oppose using ordinary car night vision devices as an aircraft blind landing system. Car night vision devices only expand the driver's field of vision beyond the range of the headlights. Therefore, before using the car night vision device, you must abide by the national traffic regulations and turn on the width headlights, otherwise it will not work safely.
