Abstract: 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.

Abstract: 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.
