From Digital Map to 3D Map: Creating 3D Map by Motion Stereo Utilizing 2D Map

摘要

This paper presents the framework for creating of 3D map. The 3D shape and the textures of a building are acquired by analyzing moving picture taken from a running vehicle. However, in the real city environment, it is difficult to obtain 3D data of buildings accurately, because the slight motion of images due to the vehicle motion cannot be removed completely. This paper describes a approach to reconstructing 3D city model utilizing existing 2D digital map in addition 3D measured data. The obtained shapes and textures are compared with 2D maps to refine their location and shape. The implementation of the alogorithm has been applied to several real urban scenes and successfully created 3D map.
