How to judge distance with car reversing camera?

[DeValerie]

The method to judge distance using a car reversing camera is: 1. Red line: indicates the warning line, which is 30cm from the rear of the car. When the car reaches near this line, the parking space is just right and no further reversing should be done; 2. Yellow line: indicates the deceleration line, which is 60cm from the rear of the car. You can continue to reverse but should slow down and check the distance; 3. Green line: indicates the normal safety line, meaning there is still ample distance between obstacles and the rear of the car, so the driver can reverse with confidence. When the vehicle is shifted into reverse gear, the reversing camera system will automatically activate the camera at the rear, displaying the situation behind the car on the central control or rearview mirror's LCD screen. At this time, a border area will appear on the screen, and the lines forming this area are the auxiliary trajectory lines of the reversing camera, reminding the driver to adjust the direction in time.
