What is the difference between 360-degree panoramic navigation 2D and 3D?

[McRose]

360-degree panoramic navigation 2D and 3D differ in accuracy, definition, and three-dimensional effect. The specific differences are as follows: 1. Accuracy: Traditional 2D navigation still has significant drawbacks, such as inaccurate navigation and unclear intersections. In contrast, 3D navigation provides drivers with a clearer 3D scene restoration in complex intersections and overpass areas. 2. Definition: 2D navigation uses raster maps, displaying the map in slices; 3D map navigation uses vector maps, which are drawn by the terminal, offering richer map functionalities. 3. Three-dimensional effect: 3D maps are drawn using vector technology on the front end, with more refined rendering effects. They can achieve three-dimensional buildings, shadows, and sky rendering. During navigation, they also provide a noticeably better three-dimensional effect and support multiple perspective switches and rotations.

I'm quite familiar with 360-degree panoramic navigation, especially having helped many friends with car repairs. The 2D mode is like a bird's-eye view from above, displaying a flat circular image on the screen that clearly marks the distance between the vehicle and obstacles. It's straightforward and easy to understand, making it ideal for quick boundary judgment during parking or reversing in narrow spaces. The 3D mode is more complex, adding depth simulation for a stronger three-dimensional effect, making surrounding objects appear as if they're truly standing there. This helps better identify steps or low-lying objects, though it can sometimes distort distances, making judgment less intuitive and consuming more system resources. Essentially, the core difference between 2D and 3D lies in view presentation: 2D emphasizes layout, while 3D focuses on realism. The system stitches images from multiple cameras, with different software algorithms at play. For driving, it's recommended to use 2D mode regularly and switch to 3D for complex turns or blind spots. Remember, performance varies by brand, and hardware upgrades might enhance the experience. Above all, safety comes first—don't just focus on flashy visuals; ensuring clear visibility of road details is key.
