What is the Difference Between a Rearview Camera and a 360-Degree Panoramic Camera?
2 Answers
The differences between a rearview camera and a 360-degree panoramic camera are as follows: 1. Different Imaging: (1) A rearview camera is specifically designed for reversing, providing a view primarily of the front and rear of the vehicle, with limited visibility on the sides. (2) A 360-degree panoramic camera offers a comprehensive view of the surroundings, allowing the driver to see all around the vehicle in a 360° rotation. 2. Different Systems: (1) The 360-degree panoramic camera employs a fisheye-style panoramic imaging optical system, ensuring no blind spots in the center and delivering high-definition output with 3 million pixels, balancing wide field coverage and resolution requirements. (2) The rearview camera, also known as a parking assist system, reverse visual system, or onboard monitoring system, is widely used in various large, medium, and small vehicles for reversing or driving safety assistance. 3. Different Principles: (1) The rearview camera system provides clear visibility even at night through infrared technology. Professional vehicle-mounted probes feature enhanced anti-magnetic, shockproof, waterproof, and dustproof performance. The onboard display uses TFT true color, with anti-magnetic treatment to eliminate signal interference and flickering. It can receive two video inputs simultaneously, play VCDs and DVDs without a decoder, and includes automatic level switching and automatic on/off functions for reversing. (2) The 360-degree panoramic camera synthesizes images from four 180-degree wide-angle cameras installed on the front, rear, and sides of the vehicle into a bird's-eye view displayed on the onboard monitor. It is particularly suitable for large SUVs and MPVs, effectively eliminating blind spots during parking and providing an aerial view of the driving environment, enhancing overall driving safety as a high-tech automotive safety device.
The reversing camera is a rear-mounted camera on the car. When shifting into reverse gear, the central display shows the rear view, mainly helping you see if there are any obstacles behind while reversing to avoid hitting walls or other vehicles. The 360-degree panoramic view system is different—it uses four cameras (front, rear, left, and right) to stitch the images into a bird's-eye view of the entire car. At low speeds or when parking, it provides a full view of the surroundings, making side-wheel positioning or front bumper blind spots clearly visible. Technically, the reversing camera only requires a simple single-camera system, is easy to install, and comes standard on most cars. The 360 system relies on multiple cameras and software stitching, requiring algorithms to correct distortions, making it more complex and prone to dirt or malfunctions, thus needing regular maintenance. In terms of advantages, the reversing camera is affordable and practical but only addresses rear visibility. The 360 system offers comprehensive coverage, preventing scrapes or low obstacles and boosting parking confidence. As someone who frequently tinkers with cars, I think the 360 system suits beginners or city driving, though retrofitting older models can be costly but worthwhile.
