What is AR technology also called?

AR technology is also called virtual reality technology. AR technology is a technology that calculates the position and angle of camera images in real time and adds corresponding images. It is a technology that skillfully integrates virtual information with the real world. AR technology is widely used in multimedia, intelligent interaction, sensing, etc. A technical means that simulates computer-generated text, images and other virtual information and applies it to the real world.

The operating environment of this tutorial: Windows 7 system, Dell G3 computer.

AR technology is also called virtual reality technology.

Introduction to AR technology

Augmented Reality (AR) is a method of calculating the position of camera images in real time The technology of adding corresponding images and angles is a new technology that "seamlessly" integrates real world information and virtual world information. The goal of this technology is to set the virtual world in the real world on the screen and interact with it.

AR technology extensively uses multimedia, three-dimensional modeling, real-time tracking and registration, intelligent interaction, sensing and other technical means to combine computer-generated text, images, three-dimensional models, music, videos and other virtual information After the simulation is applied to the real world, the two kinds of information complement each other, thereby achieving "enhancement" of the real world.

Working principle:

The three major technical points of AR: three-dimensional registration (tracking registration technology), virtual reality fusion display, Human-computer interaction. The process is to first collect data from the real scene through cameras and sensors, and pass it to the processor for analysis and reconstruction, and then update the user in real time through cameras, gyroscopes, sensors and other accessories on AR headsets or smart mobile devices. The spatial position change data in the real environment can be used to obtain the relative positions of the virtual scene and the real scene, realize the alignment of the coordinate system and perform the fusion calculation of the virtual scene and the real scene, and finally present the synthesized image to the user.

Users can collect control signals through interactive accessories on AR headsets or smart mobile devices, such as microphones, eye trackers, infrared sensors, cameras, sensors and other equipment, and perform corresponding human-computer interaction and Information updates to achieve interactive operations in augmented reality.

Among them, three-dimensional registration is the core of AR technology, which uses two-dimensional or three-dimensional objects in the real scene as markers to match virtual information with real scene information, that is, the position, size, and location of virtual objects. The motion path, etc. must perfectly match the real environment to the point where virtuality and reality complement each other.

Main Features

AR system has three outstanding features: ①Integration of information in the real world and virtual world; ②Has real-time interactivity; ③In three-dimensional scale Add positioning virtual objects in space. AR technology can be widely used in military, medical, construction, education, engineering, film and television, entertainment and other fields.
