Summary

Far-infrared detection technology extends the detection range up to 300 meters,Far-Infrared Detection: Extending Vision Up to 300 Meters Articles far beyond the reach of traditional high beam headlights. This advanced system, integral to the Night View Assist, uses thermal imaging to identify pedestrians and other critical objects, ensuring a safer driving experience. Equipped with a 24-degree viewing angle and protective features, the system converts thermal data into clear images displayed on the car's dashboard. This technology is particularly effective in highlighting pedestrians, even in complete darkness, and provides real-time alerts to drivers.

The Core of Night View Assist

The Night View Assist system is centered around a far-infrared (FIR) camera positioned at the front of the vehicle. This camera covers a 24-degree viewing angle and is protected by a glass shield that can be heated and cleaned, ensuring optimal performance in various weather conditions. The FIR camera captures thermal radiation from objects, which is then processed by a computer to generate black-and-white images displayed on the car's central dashboard.

Key Features

  • Detection Range: Up to 300 meters, far exceeding the range of automotive high beams.
  • Thermal Imaging: Captures heat signatures, making it effective even in complete darkness.
  • Protective Shield: Heated and cleanable glass shield to maintain clarity.
  • 24-Degree Viewing Angle: Wide coverage for comprehensive detection.

Enhanced Pedestrian Detection

One of the standout features of the far-infrared detection system is its ability to focus on pedestrians. Human bodies emit heat, making them appear prominently in FIR images, even in dark environments. The system can detect pedestrians within a range of approximately 100 meters.

Image Processing and Alerts

The image processing software analyzes the data to identify human contours and bright circular objects, such as heads. When a pedestrian is detected, the system highlights them with a yellow marker on the central display. If the pedestrian is deemed to be in potential danger, such as moving closer to the road, the marker turns red, and an audible warning is triggered. In Audi models equipped with a Head-Up Display (HUD), warning signs also appear on the windshield.

Customizable Settings

Drivers can customize the warning settings, including markers, sounds, and image contrast, through the MMI system. However, the system has limitations; for instance, it may not highlight pedestrians if the ambient temperature exceeds 28°C.

Technological Advancements and Industry Impact

The far-infrared detection system is a product of Huizhou Desay SV Automotive Electronics Co., Ltd., formerly Siemens VDO Automotive Electronics. Established in 1986 and acquired by Desay Group in 2010, the company has become a leading player in automotive electronics, partnering with major car manufacturers globally.
