Night vision system cannot completely replace car lights and human eyes, it is just an auxiliary device.The image on the display screen is not clear, but by capturing the heat emitter, the contrast between the light and darkness of the image is prominent, and the obstacles are displayed more eye-catching.If the oncoming vehicle also activates the active night vision system during meeting, it may affect the imaging on the display screen.The camera and sensor of the night vision system are generally integrated in the front of the car and the windshield. In the event of a collision, it may cause damage.The current automotive night vision system mainly uses thermal imaging technology, also known as infrared imaging technology.The principle is: Any object emits heat, and objects with different temperatures emit different amounts of heat. Humans, animals, and moving vehicles emit more heat than their surroundings. The night vision system can collect this information, and then transform it into a visible image, which can clearly present the objects that were originally invisible at night, and increase the safety of driving at night and car wsah clean.
