How to Determine the Distance in a Rearview Camera?

[McReagan]

Methods to determine the distance in a rearview camera are: 1. When the car image occupies the entire rearview mirror, the distance is 3 meters; 2. When the car image occupies two-thirds of the rearview mirror, the distance is 5 meters; 3. When the car image occupies half of the rearview mirror, the distance is 9 meters; 4. When the car image occupies one-third of the rearview mirror, the distance is 12 meters; 5. When the upper edge of the rear bumper of the car in front is visible at the lower edge of the front windshield, the distance is 1 meter. Important notes include: 1. When reversing, if the center of another car's wheel is visible at the lower edge of the left middle window, the left side is approximately 0.8 meters from the left car; 2. When reversing, if the center of the wheel is visible in the middle of the right middle window, the right side is approximately 1 meter from the left car; 3. When reversing, if the rear end of the bumper above the rear tire aligns with the parking line in the rearview mirror, the rear of the car is approximately 0.2 meters from the parking line.
