What is the Principle of 360-Degree Panoramic View?

Car 360-degree panoramic cameras work on the principle of using four 180-degree wide-angle cameras installed on the front, rear, left, and right sides of the vehicle. These cameras simultaneously capture images of the vehicle's surroundings. The images are then corrected and stitched together by an image processing unit to form a 360-degree panoramic top-down view of the vehicle's surroundings, which is displayed in real-time on the central console's display device. Introduction: The 360-degree panoramic imaging system, also known as the satellite panoramic driving safety system, addresses the limitations of single rearview cameras used in traditional backup radar systems. These older systems only provide a view of the area directly behind the vehicle, leaving blind spots around the vehicle's perimeter. As drivers' demands for more comprehensive visibility have increased, the need for a 360-degree panoramic view around the vehicle arose, leading to the development of the 360-degree panoramic backup camera. The 360-degree panoramic camera offers the following features: Parking assistance; Expanded field of view for navigating narrow roads and oncoming traffic; Real-time route correction via the central console; Driving recording; Parking surveillance.
The 360-degree panoramic imaging system involves installing four cameras on the vehicle—one each at the front, rear, left, and right sides. These cameras simultaneously capture the surrounding environment. The footage is then transmitted to the vehicle's processor, where an algorithm stitches it together into a complete bird’s-eye view displayed on the screen, as if the car is wearing panoramic glasses. I’ve tried this feature—during the stitching process, it corrects lens distortion and overlaps, relying heavily on precise camera angle calibration and image processing chips. Some high-end models even simulate a 3D perspective and predict wheel trajectory lines, which is particularly useful for detecting curbstones and low obstacles, offering a significantly wider field of view compared to traditional rearview cameras.
This thing is simply a parking marvel. Four wide-angle cameras cover all blind spots around the car, and the data is processed to instantly generate a bird's-eye view. I rely on it for parking in old residential areas, and it gives me confidence when navigating narrow lanes. The most practical feature is the transparent chassis function, which uses virtual rendering to show what's underneath the car. However, the cameras need to stay clean in rainy weather, or the image will blur. Although the technology is complex, it's incredibly intuitive to use—beginners can instantly drive like pros.
Last time I drove my friend's car and experienced the 360-degree panoramic view. The image was as stunning as a drone's aerial shot. Cameras are hidden around the front, rear, left, and right of the vehicle, and the processor corrects the distorted images captured by the fisheye lenses before stitching them into a single picture. Sitting in the driver's seat, I could clearly see the distance between the wheels and the curb, avoiding tire scrapes. The system can even predict the turning path based on the steering wheel angle, making it feel like using a cheat code in a video game. Installation requires precise positioning; otherwise, dark shadows may appear in the stitched image. Nowadays, even entry-level domestic cars priced around 100,000 yuan come standard with this feature—absolutely amazing!
