AR is the abbreviation of Augmented Reality, which is translated into augmented reality in Chinese. AR is a technology to calculate the position and angle of camera images in real time and add corresponding images. In other words, AR is to present virtual information in reality and let people interact with it. AR can seamlessly connect real and virtual information through technical means. Construct a three-dimensional scene of things that don't exist in reality to show them and connect them with real life.

For example, Disney once launched a game called "Disney Unlimited". Users can interact with the characters in the animation with AR technology, making people feel that the characters in the animation are around you, but in fact the protagonist in this animation does not exist.
