What is the Principle of the Rearview Camera System?
2 Answers
The principle of the rearview camera system is based on visual measurement rearview technology. It relies on a camera at the rear of the vehicle to display road condition information behind the car on the central display screen. The driver can move the square representing the vehicle body freely on the screen via the touchscreen. If the position is appropriate, the square will change from red to green. At this point, simply engage the reverse gear and control the vehicle speed to complete automatic reversing. Limitations of the rearview camera system: 1. Ice, snow, or mud covering the camera; 2. Dark environmental lighting; 3. Extreme conditions such as sun glare or headlights from a vehicle behind; 4. Deformation or damage to the rear of the vehicle; 5. Extremely high or low temperatures and significant temperature fluctuations.
Last time I got my car repaired, I specifically studied this. The reversing camera is essentially a small camera installed at the rear of the car, which can capture real-time footage of what's behind the vehicle. This camera is even more durable than a smartphone lens and isn't afraid of rainy weather. The captured footage is then transmitted via wiring to the central control screen with minimal delay. The most useful feature is the guidance lines—red, yellow, and green markers that act like game guides, directly showing you how far you are from obstacles. Some cars even come with a wide-angle function, allowing you to clearly see small stones near the wheels.
