    Abstract: The 3D information generating device includes a light source unit configured to irradiate light onto a target object, a coordinate mechanism unit disposed between the target object and the light source unit and including a plurality of inclined projections reflecting the light, a camera unit configured to output an image obtained by simultaneously photographing the coordinate mechanism unit and the target object, and an information processing unit configured to check a projection plane formed by the light of the light source unit and, by using the projection plane, generate 3D information about the target object while calibrating an error. Accordingly, an unskilled user may easily perform a 3D scan operation by using the coordinate mechanism unit, and moreover, since a coordinate mechanism is not installed in the outside, the 3D information generating device may easily move and may be easily maintained and managed.

    Abstract: An apparatus and method for generating a 3D model, in which point clouds from a scanner are automatically aligned using marker information, with markers attached to an object. The apparatus includes a point cloud refinement unit for receiving point clouds and marker sets from scanning of an object, refining the point clouds, and transmitting refined point clouds and marker sets, a point cloud alignment unit for inquiring of a point cloud and marker set database about a point cloud group of point cloud pairs and a marker set group of marker set pairs, and aligning the point cloud group, wherein the point cloud pairs and the marker set pairs are acquired by scanning a single object in different directions, and a surface generation unit for generating a 3D model by reconstructing a surface of the object based on the aligned point cloud group.

    Abstract: Disclosed herein are a method and apparatus for providing a user-customized augmented-reality service. The method is configured to extract the basic ergonomic information of a user by sensing the body of the user who is using an augmented-reality service, to generate user-customized ergonomic information by modifying the basic ergonomic information of the user based on at least one of misrecognition occurring in predefined basic interaction and user evaluation information, to detect the physical characteristics of the user by comparing the basic ergonomic information of the user with the user-customized ergonomic information, to define user-customized interaction by reflecting the physical characteristics of the user in the predefined basic interaction, to extract the unique characteristics of the user from usage data accumulated through the user-customized interaction, and to update the user-customized interaction so as to match the unique characteristics of the user.
