Abstract: Disclosed herein are a method and apparatus for generating a digital surface model using satellite imagery. The method includes correcting a geometric error in input satellite images, generating one or more depth maps using a stereo matching method based on the corrected satellite images, and generating a digital surface model by combining the generated depth maps and by estimating a height value for each location on the ground surface.

Abstract: A method for 3D printing of an object that is larger than the printing area of a 3D printer and a device using the method. The 3D printing method includes receiving 3D mesh data of the object, determining whether the 3D mesh data is included in the printing area of the 3D printer, generating partitioned mesh objects by partitioning the 3D mesh data if the 3D mesh data is not included in the printing area of the 3D printer, forming a connector for connecting the partitioned mesh objects, arranging the partitioned mesh Objects in the printing area, and printing the arranged partitioned mesh objects in 3D.
