Virtual reality 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.
2, the principle is different
Vr is a computer-generated simulation environment, a multi-source information fusion, interactive three-dimensional dynamic visual scene and entity behavior system simulation, which makes users immersed in this environment. The main principle is to establish 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.
3. Different functions
Vr can realize human-computer interaction, and there are many kinds of perceptions, which can make people completely immersed in the virtual world, while ar technology must be combined with reality, with low intelligence, and cannot interact with people and make people forget reality.
