What's the Difference Between 2D and 3D in Car 360-Degree Surround View?
3 Answers
Generally speaking, surround view systems aren't categorized as 2D or 3D - they're all technically 3D, with the main difference being the level of depth perception. Here's relevant information: 1. Surround View Parking System: The 360-degree surround view parking system displays a real-time, seamless stitched bird's-eye view of the vehicle's surroundings (with ultra-wide angles) on the car's display screen. It helps drivers understand blind spots around the vehicle, enabling more intuitive and safer parking assistance. Also known as the panoramic parking imaging system (different from segmented "surround view" displays currently on the market). 2. Function: The 360-degree surround view assist system allows drivers to see the vehicle's surroundings more clearly and compensates for human visual blind spots.
I've pondered this issue before. The 2D version of 360-degree panoramic imaging is like stitching together the footage from four fisheye lenses into a flat map. While it provides a clear view of the surroundings, the image feels flat and lacks depth. Later, I experienced the 3D version and found that it uses software to construct the images into a three-dimensional model, almost like creating a virtual figurine of the car. The most noticeable difference is when viewing the front of the car: the 3D version shows the protruding shape of the bumper, while the 2D version only displays a distorted, stitched-together flat image. Nowadays, many cars can even display the position of the wheels when turning, which is particularly useful for passing through narrow roads. New drivers no longer need to get out of the car to check the distance.
I remember once driving a friend's newly bought SUV, when shifting into reverse, the screen suddenly switched from 2D to 3D effect. The biggest difference was the significantly enhanced three-dimensional sense—the 2D view was like looking down at a map, with obstacles appearing flat. In contrast, the 3D display could even show the thickness of speed bumps on the ground, making it crystal clear where the wheels were about to roll. One time while reversing in the neighborhood, the 3D perspective clearly revealed a stone pillar hidden in the blind spot behind the car, something the flat 2D view couldn't display due to the height difference. When choosing a car, it's advisable to pay special attention to the realism of the 3D simulation—some models have overly fake renderings that aren't practical.
