What is ar?

The full name of AR is augmented reality. Translating into Chinese is augmented reality technology. It is a technology to calculate the position and angle of camera image 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 and interact with it on the screen. Let the real environment and virtual objects be superimposed on the same picture or space in real time and exist at the same time.

In fact, in our daily life, AR has gradually developed. For example, the most common is the AR scan in Alipay or the QR code on QQ. When scanning a specific product, a three-dimensional character or animation will be displayed on the mobile phone, which is vivid and interesting.
