17 Claims

1. A method of outputting a large-capacity 3D model for an augmented reality (AR) device, the method comprising:

generating a multi-texture and a 3D mesh based on a multi-view image;

generating a 3D model using the multi-texture and the 3D mesh; and

transmitting, to the AR device, an image of the 3D model in a view, to which a camera of the AR device is directed, according to camera movement and rotation information of the AR device,

wherein the AR device outputs the image in the view, to which the camera is directed.
