3.1 Overview
Augmented Reality (AR), abbreviated as "AR", is a technology that cleverly integrates virtual information with the real world. It widely uses various technological means such as multimedia, 3D modeling, real-time tracking and registration, intelligent interaction, and sensing. After simulating computer-generated virtual information such as text, images, 3D models, music, videos, etc., it is applied to the real world. The two types of information complement each other, thus achieving "enhancement" of the real world.
The AR system has three prominent features:
Integration of information between the real world and the virtual world;
Real time interactivity;
Add positioning virtual objects in three-dimensional scale space.
Augmented reality technology includes new technologies and methods such as multimedia, 3D modeling, real-time video display and control, multi-sensor fusion, real-time tracking and registration, scene fusion, etc.
There are a total of 12 AR effects in this case, which are:,
["Triangle", "Rectangle", "Parallelogram","WindMill","TableTennisTable","Ball","Arrow", "Knife", "Desk","Bench", "Stickman", "ParallelBars"]3.2、Start command
