What is the principle of a 360-degree panoramic camera in a car?

[LeahRose]

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.

As an ordinary office worker who has been driving for over a decade, I find the panoramic camera system to be a real lifesaver. Technically, it works by installing four cameras around the car - front, rear, left, and right - that simultaneously capture video footage. The vehicle's computer then combines these images to create a bird's-eye view panorama. It's incredibly convenient to use, especially when making turns or parking in congested traffic, as it clearly shows pedestrians and other vehicles around me, helping avoid accidents. The system also automatically corrects image distortions, such as those caused by camera angles, through software processing. I remember initially worrying about response time, but the real-time processing is remarkably fast with virtually no lag. While not inexpensive, the enhanced safety and convenience make it worthwhile, and I believe all new cars should come equipped with this feature.

From a safety perspective, having driven for many years, I believe the principle of surround-view cameras can significantly reduce risks. Multiple wide-angle cameras are deployed around the vehicle body to cover all blind spots. An image processor synthesizes real-time footage to output a seamless view without blind zones. The software employs pattern recognition to eliminate stitching seams, ensuring a coherent display. This is particularly crucial during reversing or turning maneuvers, effectively preventing collisions with pedestrians or obstacles. The system boasts high stability with rare errors, though regular maintenance for lens cleanliness is required.
