What is the Principle of a Car 360-Degree Panoramic Camera?

[VonDaniel]

The principle of a car 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 functions of a car 360-degree panoramic camera include: 1. Dashcam; 2. Surround-view panoramic display with automatic screen switching; 3. Vibration-activated monitoring recording when the engine is off. The components of a car 360-degree panoramic camera consist of hardware and software systems, and its purpose 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.

As an automotive technology expert, I fully understand the working principle of 360-degree surround view cameras. The system installs multiple fisheye cameras around the vehicle body - such as on the front grille, rear bumper, and under both side mirrors. These cameras capture wide-angle views but produce distorted images. The onboard processing unit then uses software algorithms to correct and stitch the images: first eliminating lens distortion-induced curvature, then seamlessly combining different viewing angles into one bird's-eye view simulation from above the vehicle. The entire process resembles drone cinematography, updating in real-time to display the vehicle's surroundings. This relies on advanced image processing technology to help drivers eliminate blind spots, especially during low-speed maneuvers or parking. Some systems further integrate sensors to enhance precision and ensure complete coverage. Maintenance is straightforward - simply clean the camera lenses regularly for optimal clarity. In summary, this system perfectly integrates hardware and software to deliver safer, more intuitive driving.

I've always relied on 360-degree cameras to assist with parking, which essentially work by capturing surrounding images through distributed cameras. When I park in tight spaces, cameras in four positions (such as the front, rear, and both sides of the car) operate simultaneously. The wide-angle lenses capture a broad view but are prone to distortion. The embedded chip in the system quickly processes the images: algorithms correct the distorted parts, then stitch all the footage into a single bird's-eye view displayed on the screen. This allows me to see details around the car in real time, such as wheel positioning and obstacle distances. In fact, it also involves image fusion technology to prevent misalignment or overlapping of the footage. I use it during city driving to reduce the risk of scratches, and although rain may cause image blurring, as long as the cameras are clean, it's fine. Overall, this design enhances convenience and confidence.

From a safety perspective, 360-degree panoramic cameras eliminate blind spot risks. The principle involves installing multiple cameras at various corner points to capture fisheye images, which the system then corrects for distortion and stitches together to form a continuous top-down view. I rely on it to monitor the rear situation when reversing, effectively preventing collisions with people or objects. This real-time processing makes the surrounding environment clear at a glance.
