Ar virtual reality technology principle
Augmented Reality (AR) is a technology that calculates the position and angle of camera images in real time and adds corresponding images, videos, and 3D models. The goal of this technology is to put the virtual world on the screen. The real world and interact. This technique was proposed in 1990. As the computing power of portable electronic products increases, it is expected that the use of augmented reality will become wider and wider. More generally, it is a new human-computer interaction technology that uses cameras, sensors, real-time computing and matching techniques to overlay real-world and virtual objects into the same picture or space in real time. Through the virtual reality system, users can experience the “immersive†realism experienced in the objective physical world. They can also break through the space, time and other objective constraints and feel the experience that cannot be experienced in the real world. Augmented reality technology, which is a new technology that integrates real world information and virtual world information "seamlessly". It is an entity information (visual information, sound, etc.) that is difficult to experience in a certain time and space of the real world. Taste, touch, etc., through computer and other science and technology, simulation and then superimposition, the virtual information is applied to the real world, perceived by human senses, thus achieving a sensory experience beyond reality. The real environment and virtual objects are superimposed in real time on the same picture or space. Augmented reality technology not only displays the information of the real world, but also displays the virtual information at the same time, and the two kinds of information complement each other and superimpose. In visual augmented reality, users can use the helmet display to combine the real world with computer graphics to see the real world around it. Augmented reality technology includes new technologies and new methods such as multimedia, 3D modeling, real-time video display and control, multi-sensor fusion, real-time tracking and registration, and scene fusion. Augmented reality provides information that is different from what humans can perceive in general. Virtual reality technology is a computer simulation system that can create and experience virtual world. It uses computer to generate a simulation environment. It is a multi-source information fusion, interactive 3D dynamic vision and system simulation of entity behavior. Immerse yourself in the environment. Virtual reality technology is an important direction of simulation technology. It is a collection of various technologies such as simulation technology and computer graphics human-machine interface technology multimedia technology sensing technology network technology. It is a challenging cross-cutting technology frontier and research field. . Virtual reality technology (VR) mainly includes simulation environment, perception, natural skills and sensing equipment. The simulation environment is a computer-generated, real-time, dynamic, three-dimensional, realistic image. Perception means that the ideal VR should have the perception that everyone has. In addition to the visual perception generated by computer graphics technology, there are also perceptions such as hearing, touch, force, and motion, and even olfactory and taste, also known as multi-perception. Natural skills refer to the rotation of the person's head, eyes, gestures, or other human behaviors. The computer processes the data that is appropriate to the actions of the participants, responds to the user's input in real time, and feeds back to the user's facial features. . A sensing device is a three-dimensional interactive device. 1. Information integration between the real world and the virtual world; 2, with real-time interactivity; 3. Adding a positioning virtual object in the three-dimensional scale space. Similar to the bear's AR-based applications, it is in line with a basic routine, which is to make the flat picture or card "stereoscopically move" through advanced AR technology. The user only needs to download the corresponding dedicated software, and the stereo image of the character can appear by scanning the AR card with the mobile device. AR technology can be widely applied to military, medical, construction, education, engineering, film and television, entertainment and other fields. At the earliest, it was applied in the field of education. Unlike traditional paper books, users can experience more realistic stereoscopic 3D animation and interactive science games by downloading software from mobile phones or tablets, which not only enhances the fun of use. Sexuality and interactivity also give children a new reading experience.
