Provided is a method of reconstructing a three-dimensional (3D) model of an object. The method includes sequentially performing, by a camera module, first and second object scanning processes of scanning the same object, reconstructing, by a processor module, a 3D object model, based on a first object image obtained through the first object scanning process, performing pose learning on an object to generate learning data, based on data obtained through a process of reconstructing the 3D object model based on the first object image, and reconstructing, by the processor module, a final 3D object model, based on a second object image obtained through the second object scanning process and the learning data.

The present disclosure provides a method and apparatus for reconstructing 3D information of an object. The method of reconstructing 3D information of an object may include: reconstructing 3D information of a background space, using at least one of images of the background space for three-dimensionally reconstructing the object; separating the object from the background space on the basis of at least one of images of the object in the background space, and of obtaining a depth image of the object separated from the background space; and generating 3D information of the object based on images taken by at least one of cameras in consideration of position relationships between the depth image of the object and the cameras.

The present invention relates to a method and apparatus for providing a realistic 2D/3D AR experience service based on a video. Particularly, the present invention provides a method of providing a realistic AR service with high quality based on AR by using a 2D video image and 3D information in association thereto at the same time, filming a cybernaut and AR content by using two sensors having viewpoints different from each other, and arranging 2D/3D content being an object to be matched within the AR content and which has a 3D position different to a position of the cybernaut in association with a dynamic 3D position of the cybernaut and with a dynamic viewpoint of a service sensor.

Disclosed herein is an apparatus and method for separating a foreground and a background. The apparatus includes a background model creation unit for creating a code book including a plurality of code words in order to separate the foreground and the background, and a foreground/background separation unit for separating the foreground and the background using the created code book. The method includes the steps of creating a code book including a plurality of code words in order to separate the foreground and the background, rearranging the cord words of the created code book on the basis of the number of sample data that belong to each of the code words, and separating the foreground and the background using the code book.
