How to Judge Left and Right Distance with Rearview Camera?
2 Answers
When the vehicle is shifted into reverse gear, the rearview camera system automatically activates the camera located at the rear of the car, displaying the rear view on the central control or rearview mirror's LCD screen. At this point, a border area will appear on the screen, and the lines forming this area are the trajectory lines for the rearview camera assistance. These lines can be considered as a simulation of the reverse parking result, with their trajectory mimicking the wheel path under current conditions, reminding the driver to adjust the steering in time. More details are as follows: 1. Red trajectory: Indicates a warning line, with a distance of 30cm from the rear of the car. When the car reaches near this line, the parking space is just right, and no further reversing is allowed. 2. Yellow trajectory: Indicates a deceleration line, with a distance of 60cm from the rear of the car. You can continue to reverse, but pay attention to slowing down and checking the distance. Green trajectory: Indicates a normal safety line, where the distance between obstacles and the rear of the car is still sufficient, allowing the driver to reverse with confidence. 3. Green trajectory: Indicates a normal safety line, where the distance between obstacles and the rear of the car is still sufficient, allowing the driver to reverse with confidence.
I've been driving and reversing for several years, and the left and right distances on the reversing camera mainly rely on those auxiliary lines. The vertical line in the middle of the screen represents the vehicle's central axis, while the lines on either side indicate the extension of the left and right edges of the car's rear. Typically, the screen is divided into color zones: green indicates a safe distance, yellow serves as a warning, and red means dangerously close. If you want to check for obstacles on either side, such as nearby cars or walls, observe which line they appear outside of to gauge the approximate distance: if they're outside the left line, it means they're closer to your left side; similarly, outside the right line means closer to the right. The reversing image has a distortion effect, making objects appear slightly farther than they actually are, so I recommend practicing parking more to get familiar with it. Combine the rearview mirror and radar sensors to improve accuracy. Never rely solely on the camera—get out and check a few times to develop a sense of distance. This method is quite practical and helps prevent scratches.
