APPARATUS AND METHOD FOR AUTOMATICALLY ARRANGING THREE DIMENSIONAL SCAN DATA USING OPTICAL MARKER

摘要

An apparatus and method for automatically arranging 3D scan data using optical markers are disclosed where non-contact type markers are adopted to automatically arrange 3D data while scanned parts of an object are neither lost nor damaged. The apparatus using optical markers for automatically arranging 3D scan data which is obtained by photographing an object at various different angles comprises: marker generating means for projecting a plurality of optical markers on a surface of the object; pattern projecting means for projecting patterns on the surface of the object in order to obtain 3D scan data of the object; image obtaining means for obtaining 2D image data of the object including the markers projected on the surface of the object and for obtaining 3D scan data of the object through the patterns projected on the surface of the object; and control means for calculating 3D positions of the markers from the relation between the 2D image data and the 3D scan data and calculating relative positions of the 3D scan data based on the 3D positions of the markers.
