The research and application of the augmented reality technology

With the rapid development of computer 3D processing capacity and the emergence of low-cost sensors, the technology of augmented reality (AR) and virtual reality (VR) has advanced quickly in recent years, especially in combination with real-world technologies. Firstly, the concepts are summarized, and the difference and connection are analyzed between AR and VR. Then, a typical AR system with software and hardware architecture was presented based on the current research achievements. Three key techniques and related research are introduced in detail. Finally, application of AR in various areas is introduced, especially in the field of military system, equipment support and training simulation.
