What technology does ar refer to? 1 We know that the new Apple 8 series and above, Huawei Mate 20 Pro and other smart phones all support AR, which can achieve accurate ranging. Even Alipay, which is very popular recently, has an ar lens in Five Blessingg, so what is AR? AR (Augmented Reality) is a technology to calculate the position and angle of camera images in real time and add corresponding images. It applies virtual information to the real world and is perceived by human senses, thus achieving sensory experience beyond reality.

AR technology combines computer simulation technology, computer graphics and multimedia technology, artificial intelligence technology, computer network technology, parallel processing technology and multi-sensor electronic technology, which simulates human sensory functions such as vision, feeling and touch, and makes users immerse themselves in the virtual environment created by computers. The emerging augmented reality technology is to integrate the computer-generated virtual environment with the real environment around users by means of display technology, interactive technology, sensing technology, computer graphics and multimedia technology, so as to convince users that the virtual environment is an integral part of their real environment from the sensory effect.

Ar technology AR can provide users with composite visual effects by using the existing real environment: the real world observed by users is integrated with the computer-generated virtual scene. When the real scene moves, the virtual objects change in the same way, as if they really exist in the real scene. Ideally, virtual objects can also make users and real objects feel ugly in a natural way. The difficulty of developing augmented reality system lies in how to determine the position of the camera relative to the real world in real time and accurately, so that the virtual scene can be seamlessly integrated with the real world.

Pokemon Go, which is popular all over the world, is the best representative of this application. After locating the player's geographical position, the system sets the types of monsters distributed in this area and the probability of their appearance. Players can find various Pokemon by following the navigation. AR technology is also used in the game, so that players can capture the throwing action of monsters and reproduce it in reality.

Its basic principle is to obtain the geographical location of users through GPS, and then obtain the POI information of objects (such as restaurants, banks, schools, etc. ) from some data sources (such as wiki and google) near this location, and then the direction and inclination of the user's handheld device are obtained through the electronic compass and acceleration sensor of the mobile device, and then the plane reference of the target object in the real scene (equivalent to the mark) is established through this information, and then the principle of coordinate transformation and display is similar to that of the mark-based ar.

This AR technology is realized by using the GPS function and sensor of the equipment, and it gets rid of the dependence of the application on the tag. User experience is better than tag-based AR, and performance is better than tag-based AR and unmarked AR, because it does not need to identify the gesture of the tag and calculate the feature points in real time. Therefore, compared with tag-based AR and tag-free AR, LBS-based AR can be better applied to mobile devices.

Zhang Gong of Beijing Sidu Technology said: AR augmented reality technology uses computer graphics technology and visualization technology to generate virtual objects that don't exist in reality, uses sensing technology to accurately "place" the virtual objects in the real environment, and uses display equipment to integrate the virtual objects with the real environment, so that users can't feel what is real and what is virtual in the scene, but think they are seeing the real scene. It can be seen that the essential feature of augmented reality is the fusion of reality and reality, that is, the computer-generated virtual environment is visually integrated with the real environment.

What technology does ar refer to? In recent years, I believe everyone is familiar with ar. AR has been used in many scenes. In addition, AR manufacturers have also developed various AR devices, which were once sought after and loved by people. The detailed explanation of AR is estimated to be less. Although AR is a popular technology in recent years, people are still vague about AR. Today, I will tell you what AR is.

So what exactly is AR technology?

AR is Augmented Reality, which is a new technology developed on the basis of virtual reality, also known as mixed reality. It is a technology to increase users' perception of the real world through information provided by computer systems. Virtual information is applied to the real world, and computer-generated virtual objects, scenes or system prompt information are superimposed on the real scene to enhance the sense of reality.

To put it more popularly, it is a brand-new human-computer interaction technology, which uses cameras, sensors, real-time calculation and matching technology to superimpose the real environment and virtual objects on the same picture or space in real time and coexist.

Through the virtual reality system, users can feel the "immersive" realism experienced in the objective physical world, and also break through the objective limitations of space and time, and feel the experience that cannot be experienced in the real world.

The application based on AR technology conforms to a basic routine, that is, the plane picture or card is "three-dimensionally moved" through advanced AR technology. Users only need to download the corresponding special software and scan the AR card with the mobile device, and the three-dimensional images of people can appear. AR technology can be widely used in military, medical, construction, education, engineering, film and television, entertainment and other fields.

What does ar mean? Technical advantage 3:

1.AR technology is not expensive. A complete VR device is close to100000 USD, but a simple AR device is just a mobile phone.

The threshold of 2.2. AR technology research and development is low. Blippbuilder, an AR company, released the AR design platform, which provided users with no coding experience with the experience of creating AR technology.

3.AR technology is widely used. Military, sales, entertainment, education, science and technology, media, tourism and medical care are all the development directions of AR augmented reality.

4.AR technology provides merchants with convenient sales methods. Coca-Cola, Starbucks, IKEA and other businesses use AR technology to make a series of interactive advertisements, so as to close the distance with consumers. AR technology will revolutionize the traditional advertising industry.

At present, AR technology is just in its infancy, and there are still many limitations in its application in daily life, and there are still many unknown fields to be explored. At the same time, the application of AR is still optimizing the consumer experience, and it is expected that AR technology will become a part of our daily life as soon as possible.

Development trend of augmented reality

AR technology may become an indispensable part of people's lives. For example, Apple CEO Cook attaches great importance to the development of AR technology. There is face recognition technology in the released iPhoneX, and the research and development of this technology can be said to be the foundation of Apple in the AR field. Perhaps in the subsequent new product release, you will find the powerful application of AR technology.

Augmented reality glasses are relatively large at present, but in the future, glasses may become smaller and smaller, just like sunglasses, which can make you use augmented reality applications easily anywhere, and may also replace mobile phones in the future to realize social, office, navigation and other applications.

Augmented reality technology will penetrate into all fields of life in the future development. For example, designers can enjoy the perspective with AR***, office white-collar workers can do PPT on the table, wall or even floor, chefs can watch cooking steps before cooking, doctors can see virtual demonstrations before surgery, and games are no longer limited to screens, bringing them into the real world. Therefore, we have reason to believe that AR technology can change people's lifestyles.
