How does the backup camera work in the Audi A7?

I am trying to understand how the backup camera system works in the Audi A7. Can someone explain the technology behind it and how it helps with parking and reversing maneuvers?

The backup camera in the Audi A7 uses high-resolution cameras and sensors to provide a clear and accurate view of the surroundings. It also utilizes advanced algorithms to detect obstacles and provide guidelines for safe parking and reversing.
