The difference between RV ar and vr

The principle is different: the main principle of vr is to build a virtual environment. The basic idea of ar is to add images, sounds and other sensory enhancement functions to the real-world environment in real time.

2. The purpose is different. The purpose of VR is to provide a fully virtualized three-dimensional space, so that users can be deeply immersed in it without being aware of it. The purpose of AR is to provide users with auxiliary virtual objects in the real environment, and its essence is only an extension of the real world in the user's field of vision.

3. AR augmented reality technology with different definitions is a technology to calculate the position and angle of the camera image in real time, and add corresponding images, videos and 3D models; Vr, also known as virtual technology, uses computer simulation to create a three-dimensional virtual world, providing users with visual and other sensory simulations, so that users have an immersive feeling.

4. Different implementation methods: VR head display technology provides different display images for users' left and right eyes by locating the user's position and using binocular parallax; AR technology realizes the interaction between virtual objects and real scenes by measuring the distance between users and objects in real scenes and reconstructing it.

5. Different technologies are used: vr is a collection of simulation technology, computer graphics man-machine interface technology, multimedia technology, sensing technology and network technology. Ar includes multimedia, 3D modeling, real-time video display and control, multi-sensor fusion, real-time tracking and registration, scene fusion and other new technologies and means.

Use:

1, ar uses: TV broadcasting field: through augmented reality technology, auxiliary information can be superimposed on the screen in real time when broadcasting sports competitions, so that the audience can get more information; Tourism and exhibition field: while browsing and visiting, people will receive the relevant information of passing buildings and watch the relevant data of exhibits through augmented reality technology.

2. Use of 2.vr: Interior design field: Using virtual reality technology, designers can build a decorated "virtual" room completely according to their own ideas, and can arbitrarily change their position in the room to observe the design effect, which not only saves time, but also saves the cost of modeling.
