How to judge distance with reversing camera?

The method to judge distance using a reversing camera is: 1. Red line: indicates the warning line, which is 30cm from the rear of the vehicle. When the vehicle approaches 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 vehicle. 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 sufficient distance between the obstacle and the rear of the vehicle, allowing the driver to reverse with confidence. The function of the reversing camera is: it enables the driver to see the situation behind the vehicle on the display while reversing, preventing accidents caused by the driver's inability to see behind the vehicle, thus making reversing safer for the driver.
Regarding how to judge distance with a rearview camera, I believe safety should be the top priority. The rearview camera typically displays colored grid lines or contour lines on the screen: the red line indicates obstacles at a very close distance, usually within half a meter, requiring caution to avoid collisions; the yellow line is a warning zone, with a distance of about 0.5 to 1 meter; the green or blue line means there is still ample space to continue reversing. Combining the rearview mirror or radar warning sounds can enhance judgment—don’t rely solely on the camera, as it has blind spots, especially for low or small objects. When reversing, operate at a slow speed and be ready to stop to observe the surroundings. In rainy weather or at night when lighting is poor, image clarity decreases, so it’s advisable to clean the lens regularly. During practice, find an open area to test a few times and familiarize yourself with your car’s guiding line system to gain more confidence in parking.
