What is the Principle of Panoramic Reversing Camera?
4 Answers
The principle of panoramic reversing camera is as follows: Four cameras record all videos around the vehicle body, which are then connected to the control host (core) via connecting cables. The control host processes the images captured by the cameras—stitching and correcting them—to restore the real images around the vehicle body. Below is a related introduction to panoramic reversing cameras: 1. Function: Panoramic bird's-eye parking assistance is more intuitive. Whether it's front-first parking, rear-first parking, or side parking, it ensures accurate positioning, improves parking efficiency, and effectively prevents scratches during parking. 2. Composition: The panoramic reversing camera system consists of two core components: cameras and an image processor.
I recently researched this, and the panoramic imaging system actually relies on the coordinated work of four wide-angle cameras on the car body. There's a fisheye camera installed at the front, rear, and under each side mirror, like giving the car four compound eyes. When you turn the steering wheel, the central control screen stitches these four images together in real time. The key lies in the image processor, which first eliminates lens distortion and then seamlessly combines the top-down perspective images into a bird's-eye view. Some car models can even simulate a 360° rotating effect, similar to the street view mode on satellite maps. Interestingly, the cameras are prone to getting dirty with mud and water in rainy weather, causing the images to blur. Last time, my neighbor's car had a green screen issue with the imaging system, and upon inspection, it turned out to be a loose wiring connector in the trunk. These small details really affect the user experience.
Ever used the panorama feature on your phone? It's pretty much the same principle. The car just hides four ultra-wide-angle lenses under the front/rear bumpers and side mirrors, each covering a 180° field of view. When you shift into reverse, the onboard computer instantly captures four video feeds, uses distortion correction algorithms to flatten the curved images, then stitches them together like a jigsaw puzzle to form a complete top-down view. Smarter models can overlay reversing trajectory lines or even automatically detect obstacles marked with red boxes. I've noticed that high-pressure car wash jets can easily misalign the cameras, causing stitching errors in the image. A friend cheaped out with aftermarket lenses, only to get snowy static in nighttime imaging—OEM compatibility matters.
Imagine yourself flying above the car looking down: The panoramic system uses four fisheye cameras to capture images, then an image processor corrects distortion and seamlessly stitches the separate views into a single top-down perspective. The key lies in calibration matching—before leaving the factory, checkerboard calibration boards are used to adjust the four-camera position parameters. Interestingly, retrofitting older vehicles with panoramic systems required drilling holes and wiring, with poor installation often resulting in black borders. Newer models now utilize AI algorithms to optimize stitching seams and even feature self-cleaning camera functions during rainy weather. Some owners complain about inaccurate parking guidance lines, which typically requires recalibration of wheel speed sensor parameters.
