How to View the Guidelines in a Rearview Camera?
2 Answers
The method to view the guidelines in a rearview camera is as follows: 1. The red line indicates the warning line, which is 30cm away from the rear of the vehicle. When the vehicle approaches this line, it should not reverse further. 2. The yellow line indicates the deceleration line, which is 60cm away from the rear of the vehicle. The vehicle can continue to reverse, but the driver should slow down and check the distance. 3. The green line indicates the normal safety line, where the distance between the obstacle and the rear of the vehicle is still sufficient, and the driver can reverse with confidence. The guidelines in a rearview camera can be divided into two types: 1. Simulated wheel trajectory lines; 2. Simulated distance marker lines. Wheel trajectory lines: Represented by two vertical solid or dashed lines, they indicate the simulated trajectory of the two rear wheels and will deflect according to the steering wheel's rotation. Simulated distance marker lines: Represented by horizontal lines in green, yellow, and red (some may also be indicated by segments on the simulated trajectory lines), they show the distance between the rear of the vehicle and obstacles.
I've been driving for over a decade and am very familiar with using the guidelines on the reversing camera. Those colored horizontal lines on the screen indicate distance: green represents a safe distance of about two meters or more, yellow is the warning zone at approximately one meter, and red means danger when you're only 30-40 cm away from an obstacle. The most important line is the red one at the rear of the car - it corresponds to your bumper position; when it's about to touch the obstacle in the image, that's when you should stop. Many cars also have turning trajectory lines - just follow them when steering to predict the wheel path, which is super convenient. Never rely solely on the camera image; always check the actual distance with your rearview mirrors, and be extra cautious when the camera gets blurry in rainy conditions.
