What is the principle of a 360-degree panoramic camera in a car?
2 Answers
The principle of a car's 360-degree panoramic camera is to synthesize the images provided by 180-degree wide-angle cameras installed at the front, rear, and sides of the vehicle into a bird's-eye view displayed on the in-car monitor. The components of a car's 360-degree panoramic camera include a hardware system and a software system. Its function is to visually monitor the surroundings of the vehicle, making it easier for the owner to drive and park while avoiding inconveniences caused by blind spots. The functions of a car's 360-degree panoramic camera are: 1. Dashcam; 2. Surround-view panoramic display with automatic image switching; 3. Vibration-activated recording when the engine is off.
I've always been a car modification enthusiast, so I'm quite familiar with how 360-degree panoramic cameras work in vehicles. These systems typically have four small cameras installed at the front, rear, and beneath the side mirrors on both left and right sides. Each camera captures a wide-angle image that sometimes appears distorted, like a fisheye effect. The vehicle's processor then stitches these images together, using software algorithms to correct distortions and seams, creating a seamless top-down view. The system also adjusts brightness and contrast in real-time to ensure clear images on the display screen. While the principle sounds simple, it's incredibly helpful for avoiding scratches during parking and reversing, especially in tight urban spaces where it significantly reduces blind spots. Proper camera alignment during installation is crucial - otherwise the composite image might be inaccurate. I think this technology is becoming increasingly intelligent, even capable of integrating with parking sensors.
