What does a complete augmented reality system include?

A complete augmented reality system is realized by a set of closely connected, real-time working hardware components and related software systems. (Recommended study: phpstorm)

Augmented Reality technology is a technology that cleverly integrates virtual information with the real world. It widely uses multimedia, Three-dimensional modeling, real-time tracking and registration, intelligent interaction, sensing and other technical means can simulate computer-generated text, images, three-dimensional models, music, video and other virtual information and apply it to the real world. Two kinds of information complement each other to achieve "enhancement" of the real world.

Monitor-Based

In the AR implementation based on the computer display, the real-world image captured by the camera is input into the computer and generated with the computer graphics system The virtual scene is synthesized and output to the screen display. The user sees the final enhanced scene picture on the screen. Although it is simple, it does not bring much immersion to the user.

Optical see-through

Head-mounted displays (HMD) are widely used in virtual reality systems to enhance the user’s visual immersion. . Researchers of augmented reality technology have also adopted similar display technology, which is the transmissive HMD that is widely used in AR.

According to the specific implementation principles, it is divided into two categories: optical see-through HMD (Optical See-through HMD) based on optical principles and video see-through HMD (Video See-through HMD) based on video synthesis technology ).

The optical see-through augmented reality system has the advantages of simplicity, high resolution, and no visual deviation. However, it also has shortcomings such as high positioning accuracy requirements, difficulty in delay matching, relatively narrow field of view, and high price.

Video see-through

The video see-through augmented reality system uses a video see-through HMD (Video See-through HMD) based on video synthesis technology.
