Apparatus and method for generating 3d model

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.
