What is the AR technology of the Spring Festival Gala?

AR technology, which means reality enhancement technology in Chinese, is a technology to calculate the position and angle of camera images in real time and add corresponding images, videos and 3D models. The goal of this technology is to put the virtual world in the real world on the screen and interact with it.

Augmented reality technology not only shows the information of the real world, but also shows the information of the virtual world. The two kinds of information complement each other and overlap each other. In visual augmented reality, users can synthesize the real world and cg animation through the helmet-mounted display and see the real world around them.

Working principle of AR technology:

1. The basic idea of the early prototype of mobile augmented reality system is to add sensory enhancement functions such as images and sounds in real time in the real world environment. Sounds simple. That's right, but what the TV network does is to display still images, which can't be adjusted with the movement of the camera.

2. Augmented reality is far more advanced than any technology you see in TV broadcast, although the early versions of augmented reality first appeared in TV games and football games, such as Racef/x and the first added offensive line, which were created by SporTVision.

3. In various universities and high-tech enterprises, augmented reality is still in the primary stage of research and development. Finally, perhaps by the end of this decade, we will see the first batch of augmented reality systems put on the market in large quantities. One researcher called it "2 1 century walkman".

4. Augmented reality should not only add images to the real environment in real time, but also change these images to adapt to the rotation of the user's head and eyes, so that the images are always within the user's visual angle.
