The present invention relates to a method and an apparatus for providing an augmented reality by improving an image recognition rate in an image.

Augmented Reality (AR) is a technology that superimposes a 3D virtual image on a realistic image or background and displays it as a single image. Augmented Reality is also called Mixed Reality (MR), and augmented reality was introduced to the world for the first time in 1990 when Boeing, an airplane manufacturer, added a virtual image to the airplane assembly process.

Augmented reality and virtual reality are similar, but they are clearly distinguished according to whether they are virtual or real. As a computer game, for example, a virtual reality fighting game is a character that replaces me in an imaginary space, while an augmented reality fighting game is a form in which I confront a virtual enemy in a real space. Therefore, the augmented reality is more realistic than the virtual reality.
