The current situation of augmented reality technology in China, what is not the related technology o

Summary. Hello dear. Three key technologies.

Three-dimensional registration technology, virtual and real fusion display technology, human-computer interaction technology.

In order to solve the three major problems in the development of augmented reality application systems, it is necessary to solve the three key technologies.

Three-dimensional registration technology.

Three-dimensional registration technology is the basic technology to realize the application of mobile augmented reality, and it is also the key to determine the performance of mobile augmented reality application system, so three-dimensional registration technology has always been the focus and difficulty of mobile augmented reality system research.

The main task: to detect the pose state of the camera relative to the real scene in real time, determine the position of the virtual information that needs to be superimposed in the projection plane, and display the virtual information in the correct position on the screen in real time to complete the three-dimensional registration.

There are three criteria for judging the performance of registered technology: real-time, stability, and robustness.

What is not a related technology for augmented reality.

Kiss, are you doing a multiple-choice question? None other than these three.

The essence of virtual reality technology is to replace the real world with virtual things, while augmented reality technology is to amplify information on the actual environment.

If we extrapolate from existing systems, it's clear that high-resolution displays will proliferate rapidly: from small handheld or wrist-worn devices to large screens embedded in desks, walls, or floors, they will undoubtedly become ubiquitous. But I and many other computer scientists believe that a completely different type of user interface, called augmented virtual reality, will have a much more profound impact on the future of computers and how we interact with them.

Having the right information at the right time and place is key to all applications of this type. Personal digital assistants (PDAs) such as the PALM and PocketPC can provide timely information using wireless networks and a Global Positioning System (GPS) receiver that continuously tracks the handheld.

However, what makes AR special is the way it presents information: it doesn't have to use a separate display, but it integrates with the user's senses. As the user's attention switches back and forth between the real world and the computer screen, this interface minimizes the extra effort he spends.

In AR, the world seen by the user is literally one with the computer interface.

<> augmented reality (AR) is a computer graphics technology that can superimpose virtual images or information into the real world, so that users can see objects or information displayed in augmented reality, thereby enhancing the perception and understanding of the real world. AR technology typically uses a system of hardware such as cameras, displays, sensors, and computing devices to overlay virtual elements in the real world, where users often need to wear AR glasses or a device such as a mobile phone to observe the content presented by the AR app. AR technology has a wide range of applications in gaming, education, healthcare, entertainment, industrial manufacturing, and other fields.

Augmented Reality (AR) is a technology that calculates the position and angle of a camera image in real time and adds the corresponding image, with the goal of putting the virtual world in front of the real world on the screen and interacting with it.

This technique was first proposed in 1990. With the improvement of the computing power of portable electronic products, the use of enhancing the reality of wisdom loss is becoming more and more extensive.

Augmented reality (AR) is the entrance to the connection between the virtual and the real, and unlike the virtual world immersion advocated by devices such as Oculus, AR focuses on the connection between the virtual and the real in order to achieve a more shocking augmented reality experience.

At present, the mainstream AR refers to the superposition of virtual information on a certain position based on the recognized object through device recognition judgment (two-dimensional, three-dimensional, GPS, somatosensory, facial and other recognition), and displayed on the device screen, which can interact with virtual information in real time. To sum up, it is identification, virtual and real combination, and real-time interaction.

Virtual reality (VR) was proposed by Jaron Lanier, the founder of VPL in the United States, in the early 80s of the 20th century. Specifically, it is a technology that provides an immersive feeling in a computer-generated, interactive three-dimensional environment by using computer graphics systems and various reality and control interface devices.

Among them, the computer-generated, interactive three-dimensional environment becomes the virtual environment (i.e., virtual environment, abbreviated as VE).

I'm sure the answers to the above two systems are all advertisements, and now augmented reality is in a commercial exploration stage, and there are two major directions, one is to do hardware exploration, and the other is software adaptation and development. I don't have to say much about the hardware, there are no very good hardware manufacturers in China, and now there are only two kinds of mainstream hardware: 1 Google Glass 2 Microsoft Glass. Software development is also divided into two directions: 1 is custom development, which is mostly used in some creative marketing and retail.

Another direction is to choose software products that are developed in specific industries, such as the real estate industry, early childhood education industry, etc.

Augmented reality displays that overlay computer-generated graphics onto the real world. Since Pong entered the video game hall in the early 70s of the twentieth century, ** games have been in our lives for more than 30 years, but they have been confined to the 2D world on the screen, and the arrival of augmented reality, a new technology, will further blur the line between the real world and the computer-generated virtual world by enhancing our seeing, sounding, smelling, touching and hearing.

Augmented reality is closer to the real world in terms of the spectrum between virtual reality (creating immersive, computer-generated environments) and the real world. Augmented reality adds images, sounds, touches, and smells to the natural world in their form of existence. It is envisaged that gaming will drive the development of augmented reality, but the technology will be limited to more than that, and there will be countless applications.

Everyone from tour groups to the military can benefit from this technology to put computer-generated images in their field of view.

Augmented reality will truly change the way we see the world. Imagine yourself walking or driving on the road. With an augmented reality display (which eventually looks like a normal pair of glasses), an informational image will appear in your field of vision, and the sound will be in sync with what you see.

This enhanced information will be updated at any time to reflect the activity of the brain at that time. In this post, we'll take a look at this futuristic technology, what it consists of, and how to use it.

Google Glass, released by Google, is the only hardware device in the world that truly implements augmented reality.
