What is the principle of ar photography?

The image processed by AR augmented reality technology seamlessly blends the real scene with the virtual scene, giving the audience a deep sense of being there. Because there are many factors involved in AR application system, the research objects of AR are very extensive, including signal processing, computer graphics and image processing, man-machine interface and psychology, mobile computing, computer network, distributed computing, information acquisition and information visualization, and the design of new displays and sensors.

Although AR system does not need to display a complete scene, it needs to analyze a large number of positioning data and scene information to ensure that computer-generated virtual objects can be accurately positioned in the real scene. Therefore, the working principle of AR system includes the following four basic steps: 1, obtaining real scene information; 2. Analyze the real scene and camera position information; 3. Generate a virtual scene; 4. Video merging or direct display, that is, the graphics system first calculates the affine transformation of the virtual object coordinates to the camera viewing plane according to the camera position information and positioning marks in the real scene, then draws the virtual object on the viewing plane according to the affine transformation matrix, and finally displays it on the ordinary display directly through the S-HMD reality or after merging with the video of the real scene.

In AR augmented reality system, imaging equipment, tracking and positioning technology and interactive technology are the supporting systems to realize a basic system. AR augmented reality is a supplement to the real world, not a complete replacement. With the development of computer technology, augmented reality technology has gradually become one of the main directions of the next generation of man-machine interface technology. AR augmented reality is a high-level human-computer interface, which is characterized by interactivity and conceiving. Users can not only feel the "immersive" realism experienced in the objective physical world through the virtual reality system, but also break through the objective limitations such as space and time, and feel the experience that cannot be experienced personally in the real world. Enjoy the research and development of AR augmented reality shooting technology for 2 years. With the initial prototype, we can communicate with you and improve the progress of AR shooting technology.
