What is augmented reality (AR) technology?

Augmented reality (AR) is also called mixed reality. It uses computer technology to apply virtual information to a real computer. In the real world, real-world environments and virtual objects remain super on the same screen or place. Therefore, it is quite popular. If you have personally experienced augmented reality , you will feel its infinite charm.

Augmented reality travels between virtual reality and reality. Although virtual reality has attracted the attention of the public, the society we live in is after all a society that combines reality and virtuality. That is the perfect unity. Augmented reality will eventually prove its wide range of uses.

Augmented reality is in the field of information, especially the use of technologies such as the Internet and global satellite positioning. The combination of these technologies has unlimited development space.

Augmented reality provides information that is different from what humans can normally understand. It displays not only real-world information, but also virtual information at the same time. The two types of information complement and overlap each other. In visual augmented reality, users can use the helmet-mounted display to combine the real world with computer graphics, and then they can see the real world surrounding it.

There are already many practical applications abroad. In Germany, engineers and technicians can fully display the internal structure of the machine, as well as its related information and data, through the helmet display during mechanical installation, maintenance, and adjustment. And you can follow the instructions of the computer to work and solve technical problems. Make our work very convenient, fast and accurate. Abandoning us before, we need to carry a lot of cumbersome information with us, working and looking up, once there are problems, emergencies, and backward methods and phenomena that are at a loss.

In medical treatment, doctors can use augmented reality to easily perform precise positioning of the surgical site.

In the military aspect, the troops can use augmented reality to identify the location and obtain important military data such as geographic data of the current location.

In aviation and navigation, pilots can easily, quickly and accurately obtain relevant information such as geography, weather, climate, etc. through the augmented reality system to ensure the smooth completion of aviation and navigation work.

In terms of tourism and exhibitions, while browsing and visiting, people will receive relevant information about buildings passing by and watch relevant data about exhibits.

In terms of education, the magic book is a typical example. Magic books look no different from ordinary books, they also have pictures and text. When readers are watching the pages of a book while wearing a helmet-mounted display, you can see three-dimensional objects, immerse in the three-dimensional virtual world depicted in the book, and swim with other readers in the form of miniature virtual substitutes. Magic books are very interesting, especially for most children.

In the fields of entertainment, games, and education, the application prospects of augmented reality are more extensive. The augmented reality quake game allows players located in different locations around the world to enter a real natural scene together and conduct online battles in the form of virtual avatars.

Augmented Reality (AR) is a technology that uses virtual objects to "enhance" real scenes. Compared with virtual reality, it has the advantages of strong sense of reality and less modeling workload. It can be widely used in engineering design, modern display, medical treatment, military, education, entertainment, tourism and other fields. The Battelle Institute in the United States listed 10 technological trends of the most strategic significance in 2020 in a research report. These trends will determine the characteristics of social development in the future. Among them, the 10th place is augmented reality technology.

Domestic companies that research AR systems include Beijing Institute of Technology, National University of Defense Technology, Xi’an Petroleum Institute, University of Electronic Science and Technology, Huazhong University of Science and Technology, Shanghai University, etc. Foreign companies that research AR systems include SIEMENS AG in Germany, Columbia University in the United States, Vienna University in Australia, Japan’s Nara Association, etc. These units have achieved certain results in the AR system’s camera correction algorithm, AR head-mounted display design, hardware platform application, and visual tracking technology.

There are as many as 108 international patents related to augmented reality systems, and the time is concentrated from 1995 to the present. Among them, a newly published German patent DE10108064 describes an augmented reality system that uses video or audio information for integrated visual tracking. The system consists of the following parts: Target tracking system, in order to detect information and report its location; image recording unit, record images and convert the format; annotation system, synthesize location data, archive data.

In the same year, the US patent US2002191003 related to the augmented reality display technology uses a camera to locate the position of an object and report it to a connected computer to present the image. This method can present weather, dangerous situations etc. And the image obtained through computer image processing makes the audience Immersive, its main applications include navigational safety control assistance, pilot training, emergency training, etc. However, there are few domestic patents involving augmented reality , and domestic research on augmented reality systems is still in its infancy.
