Abstract: Disclosed herein are an apparatus and method for reconstructing a 3D model. The apparatus for reconstructing a 3D model includes an image acquisition unit for acquiring multi-view images by receiving image signals captured by multiple drones using cameras, a geometric calibration unit for estimating motion variables of the drones based on the acquired multi-view images, and a 3D model creation unit for reconstructing a 3D model of a dynamic object from the matched multi-view images using a multi-view stereo method.

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: Disclosed herein is an operating method of an apparatus for generating 3D geographic data. The operating method may include receiving multi-view images, generating a 3D mesh and texture for a first distance view from the multi-view images, generating hybrid Digital Surface Model (DSM) data for a second distance view using the 3D mesh and the texture, and generating DSM data for a third distance view using the 3D mesh and the texture.
