What is ar navigation

AR navigation, also known as "augmented reality navigation", is an innovative map navigation interaction method. Its principle is to capture real images in real time through cameras, combined with map navigation guidance information and vehicles and roads recognized by visual AI. , pedestrians and other scene objects, generate a virtual 3D navigation guidance model, and integrate and overlay it on the display screen to create a more intuitive navigation experience. AR navigation significantly reduces the cost of reading traditional 2D electronic maps for drivers, and assists users in making faster and more accurate action decisions in various key scenarios such as turns, forks, and lane changes.

The operating environment of this tutorial: HarmonyOS 2 system, HONOR V30 mobile phone.

AR navigation is also called AR HUD (Augmented Reality Head-Up Display), which can display route navigation, driving assistance, traffic reminders, business district introductions and other information on mobile phone screens, car screens, and even windshields . The full English name of AR is Augmented Reality, and Chinese means augmented reality. Therefore, the combination of AR and navigation can also be understood as augmented reality navigation.

AR navigation (AugmentedReality Navigation, augmented reality navigation) is an innovative map navigation interaction method. Its principle is to capture the real picture in real time through the camera, and then combine it with the map navigation Guidance information and scene targets such as vehicles, roads, and pedestrians recognized by visual AI generate a virtual 3D navigation guidance model, which is integrated and superimposed on the display screen to create a more intuitive navigation experience. In this way, drivers can learn more comprehensive and realistic road condition information through AR navigation, which can better assist drivers in driving and make some preparations in advance.

ar navigation is an Android mobile car navigation system designed with augmented reality technology (AR) using the GPS and camera in the mobile phone. The user can directly navigate through the camera. The virtual route guidance is intuitive and easy to understand. In addition to relieving the driver of the burden of mapping the map and surrounding roads, the driver will not miss the vehicle condition and affect driving safety when visually viewing the navigation screen.

ar navigation significantly reduces the cost of reading traditional 2D electronic maps for drivers, and assists users to make faster and more accurate action decisions in various key scenarios such as turns, forks, and lane changes.

Taking the merging problem that novice drivers often face as an example, AutoNavi AR Navigation will intelligently provide guidance at the right time based on dynamic and static data such as navigation planning, current positioning, vehicle speed, road conditions, and image recognition of lanes. When a lane change and merging reminder appears, the user can just follow the arrow while ensuring safety.

AR system has three outstanding characteristics:

1. Information integration between the real world and the virtual world;

2. It has real-time interactivity;

3. It adds positioning virtual objects in the three-dimensional scale space. AR technology can be widely used in military, medical, construction, education, engineering, film and television, entertainment and other fields.

Augmented reality technology includes new technologies and methods such as multimedia, three-dimensional modeling, real-time video display and control, multi-sensor fusion, real-time tracking and registration, and scene fusion. Augmented reality provides information that is different from what humans can perceive under normal circumstances.

Expand knowledge: The difference between VR and AR in navigation

AR focuses more on the actual navigation experience, while VR focuses more on the immersive navigation experience.

AR navigation is a real-time dynamic picture. It is necessary to turn on the mobile phone camera at the scene to collect real-time pictures. It has an enhanced effect on the real scene and effectively solves the problem of disorientation of some users. Large indoor and outdoor scenes such as shopping malls, hospitals, government centers, courts, stadiums, parks, parks, transportation, etc. are more inclined to AR navigation.

VR navigation is a static picture, and the scene can be arranged in advance for shooting. Users can browse VR panoramic images online and offline. VR panoramic navigation can deploy navigation all-in-one terminals and mobile terminals, but the on-site layout environment will change later. , the panorama needs to be retaken and uploaded. Due to its immersive and private characteristics, VR pays more attention to the user's sensory experience and is mostly used in exhibition halls, art galleries, and games.
