What is Augmented Reality?

Augmented Reality (Augmented Reality, AR for short) is a technology that calculates the position and angle of the camera image in real time and adds the corresponding image. It is a new technology that integrates the real world information and the virtual world information "seamlessly". The goal of this technology is to put the virtual world on the screen and interact with it. ^[1] This technique was first proposed in 1990. With the increase in computing power of portable electronic products, the use of augmented reality is becoming wider and wider. ^[2]

Augmented Reality (AR), also known as AR

The AR system has three outstanding features: information integration of the real world and virtual world; real-time interaction; adding positioning virtual objects in a three-dimensional scale space. AR technology can be widely used in military, medical, construction, education, engineering, film and television, entertainment and other fields. ^[1]

A complete augmented reality system is implemented by a set of tightly connected, real-time working hardware components and related software systems. There are three commonly used forms.

Monitor-Based

In a computer monitor-based AR implementation, a real-world image captured by a camera is input into a computer, synthesized with a virtual scene generated by a computer graphics system, and output to a screen display. The user sees the final enhanced scene picture on the screen. Although it is simple, it cannot bring users a lot of immersion. The implementation scheme of Monitor-Based augmented reality system is shown in the figure below.

AR technology not only has a wide range of applications in areas similar to VR technology, such as cutting-edge weapons, aircraft research and development, data model visualization, virtual training, entertainment and art, etc. The enhanced display output has more obvious advantages than VR technology in the fields of medical research and anatomy training, precision instrument manufacturing and maintenance, military aircraft navigation, engineering design, and remote robot control. ^[1]

An early prototype of a mobile augmented reality system, the basic idea of augmented reality was to add images, sounds, and other sensory enhancements to the real-world environment in real time. It sounds very simple. Also, hasn't television networks been doing this for decades with images? But all TV networks do is display still images that cannot be adjusted as the camera moves. Augmented reality is far more advanced than any technology you've seen on TV broadcasts, although earlier versions of augmented reality first appeared in TV-based games and rugby games, such as Racef / x and the first offense added Lines, they are all created by SporTVision. These systems can only display images that can be seen from one perspective. The next generation of augmented reality systems will display images that can be seen from the perspective of all viewers.

Among various universities and high-tech enterprises, augmented reality is still in the initial stage of research and development. In the end, probably by the end of this decade, we will see the first batch of augmented reality systems that are on the market. One researcher calls it "the 21st century walkman." Augmented reality is trying not only to add images to the real environment in real time, but also to change these images to adapt to the user's head and eye rotation so that the image is always within the user's perspective. ^[2]

There are hundreds of possible applications for this technology, with gaming and entertainment being the most obvious applications. Any system that can provide people with instant information without the need for people to participate in any research is valuable to all in a lot of fields. Augmented reality systems can instantly recognize what people see, and retrieve and display data related to that scene.

Repair and construction-Augmented reality can connect markers to specific objects that people are working on,

As a new type of human-machine interface and simulation tool, AR has received increasing attention and has played an important role, showing great potential.

AR is a science and technology that gives full play to creativity, provides a powerful means for the intelligent expansion of human beings, and has a huge and far-reaching impact on production methods and social life.

With the continuous development of technology, its content is bound to continue to increase. With the continuous decline in the price of input and output devices, the improvement of video display quality, and the practicality of very powerful but easy-to-use software, the application of AR is bound to grow. AR technology has brought revolutionary changes in many fields such as artificial intelligence, CAD, graphic simulation, virtual communication, remote sensing, entertainment, and simulation training.

Generally speaking, augmented reality is in its infancy in China, and many companies in the field of virtual reality have begun to focus on the development and application of "augmented reality". For example, the VRP12.0 developed by China Television Code Digital Technology integrates the function of augmented reality.

Urban Lens is the first smartphone application in China that integrates the latest AR (augmented reality) technology of mobile internet. And is committed to creating a new city tour guide, tour guide, shopping guide, attractions and tourists, merchants and users seamlessly link the new mobile Internet multi-resource integration platform.

Hold up the machine and look in the direction you want to go. The whole street is full of shops and public facilities. The camera's real-world display function lets you see, hear, and smell, giving you an immersive, novel and interesting navigation experience. Another direction is completely different search results, the so-called "city lens mobile phone, the front and the left are different." Give users a new and useful navigation experience.

The application integrates all the information needed in people's lives such as tourism, catering, entertainment, shopping, life, and media in each city, and has accurate AR (augmented reality) data navigation to easily locate and guide users. Therefore, it is convenient, fast and effective to help people choose what they need and improve the quality of urban life.

The software also provides comprehensive city indoor navigation, attraction park navigation and other strategies: such as city overview, attraction park navigation (tour introduction, distance, waiting time, etc.), commercial area indoor navigation, city features and cultural recommendations, etc. Easily experience the local essence, and make the best and most comprehensive new platform for city tour guides, tour guides and shopping guides.
