What is the purpose of the night vision feature in the Audi A8?

I am researching the Audi A8 and came across the night vision feature. What does it do and how does it work?

The night vision feature in the Audi A8 uses infrared technology to detect and display potential hazards such as pedestrians or animals on the road ahead of the vehicle. It works by projecting infrared light onto the road and using a camera to capture the reflected light. This allows the driver to see objects that may not be visible with just the headlights alone.
