What is the Difference Between 360-Degree Surround View and Rearview Camera?
3 Answers
360-degree surround view provides an ultra-wide perspective, while the rearview camera, also known as the reverse visible system or onboard monitoring system, serves a different purpose. The main differences between 360-degree surround view and rearview camera are as follows: 1. Imaging: The rearview camera is specifically designed for reversing and only displays the vehicle's front and rear conditions. In contrast, the 360-degree surround view captures a full circle of the vehicle's surroundings, showing road conditions all around. 2. System Differences: The 360-degree camera employs a fisheye panoramic imaging optical system with no central blind spots, offering 3 million pixels for high-definition output. The rearview camera system is widely used in various large, medium, and small vehicles for reversing or driving safety assistance. 3. Principle Differences: The rearview camera system uses a TFT true-color display with anti-magnetic treatment to eliminate signal interference and flickering. It can receive two video inputs simultaneously, play VCDs and DVDs without requiring a decoder. The 360-degree 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 in-car monitor.
The main difference between 360-degree surround view and reversing camera lies in the field of view. The reversing camera uses a rear-mounted camera that specifically displays the area behind the vehicle when reverse gear is engaged, helping drivers see rear obstacles. The 360-degree system combines feeds from four cameras (front, rear, left, right) to create a bird's-eye view of the entire vehicle, simultaneously showing all surrounding areas. This proves particularly useful in narrow-road encounters or parallel parking by displaying wheel positions and curb distances. Some advanced 3D 360 systems even allow perspective switching to view undercarriage details. However, installing 360 systems requires door panel removal for wiring, costing about 1,000 RMB more than basic reversing cameras. Experienced drivers may find reversing cameras sufficient, while beginners or large vehicle owners would benefit more from the comprehensive visibility of 360 systems.
Simply put, it's a difference in perspective. A reversing camera only solves the blind spot issue when backing up, acting like a dedicated camera for the rear of the car. The 360-degree panoramic camera is much more advanced, with cameras installed on the front, rear, left, and right sides. The onboard computer stitches these four images together to create a bird's-eye view from the top of the car. It's particularly useful when parking in tight spots like underground garages in shopping malls, where you can even see how many centimeters your wheels are from the curb. Nowadays, high-end models with 360-degree panoramic cameras can even recognize parking lines and perform automatic parking. However, opting for a factory-installed panoramic system is significantly more expensive than retrofitting a reversing camera later, and the wiring is more complex. For those who frequently navigate narrow roads in urban villages, the 360-degree panoramic system is definitely worth considering.
