This article mainly introduces what is the meaning of AR technology in the Internet. It is very detailed and has a certain reference value. Interested friends must finish reading it!

AR technology is also called virtual reality technology. AR technology is a technology that skillfully combines virtual information with the real world, which is widely used in multimedia, intelligent interaction, sensing and other technical means. Computer-generated text, images and other virtual information is applied to the real world after simulation.

AR technology is also called virtual reality technology.

AR technology is a technology that skillfully combines virtual information with the real world, and widely uses a variety of technical means, such as multimedia, three-dimensional modeling, real-time tracking and registration, intelligent interaction, sensing and so on. The computer-generated virtual information, such as text, image, three-dimensional model, music, video and so on, is applied to the real world, and the two kinds of information complement each other, so as to realize the "enhancement" of the real world.

How it works:

Three main technical points of AR: three-dimensional registration (tracking registration technology), virtual reality fusion display, human-computer interaction. The process is to first collect the data of the real scene through the camera and sensor, and then pass it to the processor for analysis and reconstruction, and then update the user's spatial position change data in the real environment in real time through the AR head display or the camera, gyroscope, sensor and other accessories on the intelligent mobile device, so as to get the relative position between the virtual scene and the real scene. Realize the alignment of the coordinate system and calculate the fusion of the virtual scene and the real scene, and finally present the composite image to the user.

Users can collect control signals through AR head display or interactive accessories on intelligent mobile devices, such as microphone, eye movement tracker, infrared sensor, camera, sensor and so on, and carry out corresponding human-computer interaction and information update to realize interactive operation of augmented reality.

Among them, three-dimensional registration is the core of AR technology, that is, taking two-dimensional or three-dimensional objects in the real scene as markers, the virtual information is matched with the real scene information, that is, the position, size and motion path of the virtual objects must be perfectly matched with the real environment.
