Night vision in cars

According to published data, the Automotive night vision system can reduce the accident rate by 35% at night

Automotive night vision is one of the newest technologies used in luxury and modern vehicles. The Automotive night vision system is able to provide a better image by analyzing the temperature of the elements around the car. The night vision technology was first used in military weapons during the Second World War, but with the end of the war and the spread of technology in various fields, the automotive industry also use some. Today, Night Vision can be seen in luxury cars like the new DS products. Night vision systems use an infrared sensor typically in the grille to look for warm objects in the roadway. The sensor is a video camera that captures the infrared spectrum just above visible light. The sensor outputs the moving image to a dashboard display. Increasingly, that’s coupled with sophisticated algorithms that detect humans and large animals, and most recently, that sound an alert. This is the case for all night vision technologies.

How does the Night Vision system work in cars?

The most important part of night vision technology in cars is NVD lenses; they can transform the three primary colors of red, green, and blue (RGB) into a single color. The NVD lenses mechanism is in the form of a three main color, display, brightness or darkness, so the image we see from these lenses is in such a way that different objects and elements based on the illumination they produce and they separated from each other by brightness. The more colorful the pigment is, the lighter the NVD lens reflects. That’s why NVD lenses can be very efficient at a time when the road is completely dark and there is no light; however, they can display objects and elements based on the color they reflect, but if we only want these lenses in automotive night vision systems, we will surely get into trouble. Because some light in the environment can distract all the images released by NVD lenses, the experts in the field in the automotive industry have been trying to connect these lenses to Thermographic cameras. These cameras can display the temperature reflected by the animals or humans and objects. This makes the driver able to identify animals and pedestrians from the rest of the elements on the road. The combination of NVD lenses and thermographic cameras in Automotive night vision systems allows the absolute darkness to examine all the elements of the upcoming path separately. In the new DS cars, the night vision system is located behind the logo of the Front and the image is displayed on the small screen in front of the driver. The engineers of DS company also made it possible to automatically detect animals and pedestrians by new driver assistance technologies.

According to published data, the Automotive night vision system can reduce the accident rate by 35% at night, but it’s currently just seen in luxury and modern cars and It is not massively used in the automotive industry. Since feedback has been very positive about the use of the night vision system in cars, we expect to see this technology spread across cars in the next decade.
