전 방향 이미지와 디지털 맵을 활용한 3차원 실사 도시모델 생성기법 연구

Abstract

3D city model, which consisted of the 3D building models and their geospatial position and orientation,is becoming a valuable resource in virtual reality, navigation systems, civil engineering,etc. The purpose of this research is to propose the new framework to generate the 3D citymodel that satisfies visual and physical requirements in ground oriented simulation system. Atthe same time, the framework should meet the demand of the automatic creation and cost-effectiveness,which facilitates the usability of the proposed approach. To do that, I suggest theframework that leverages the mobile mapping system which automatically gathers high resolutionimages and supplement sensor information like position and direction of the image. And toresolve the problem from the sensor noise and a large number of the occlusions, the fusion ofdigital map data will be used. This paper describes the overall framework with major processand the recommended or demanded techniques for each processing step.
