Reconstruction Textured Urban 3D Model by Fusing Ground-Based Laser Range Image and CCD Image

摘要

In this paper, a method of fusing ground-based laser range image and CCD image for the reconstruction of textured 3D urban object is proposed. An acquisition system was developed to capture laser range image and CCD image simultaneously from the same platform. The registration of laser range image is achieved by finding corresponding planar faces which are extracted from laser range images. Texture data are projected onto TIN-based object surfaces derived from laser range data. Through an outdoor experiment for reconstructing a building at IIS, University of Tokyo, it is demonstrated that textured 3D model of a building can be generated in an automated manner.
