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

ground-based laser range finder have got more concerned. In our previous research, a method of automated In this paper, a method of fusing ground-based laser registration of two views of laser range image was range image and CCD image for the reconstruction of proposed [4,51, and showed promising results with some textured 3 0 urban object is proposed. An acquisition preliminary experiment. The drawback of 3D spatial system was developed to capture laser range image and model generated only using laser range finder is it has CCD image simultaneouslyfiom the same plaform. The poor understandability or interpretability, because it is registration of laser range image is achieved by finding rather difficult to find out correspondence between TINcorresponding planar faces which are extracted from based 3D surfaces and the real world or what users can laser range images. Texture data are projected onto TINSeebased object surfaces derived from laser range data. Through an outdoor experiment for reconstructing a In contrast to the previous a~~roachesv this Paper building at IIS, Universio of Tokyo, it is demonstrated describes an attempt to reconstruct textured urban 3D that textured 30 model of a building can be generated in model employing both ground-based laser range finder an automated manner. for 3D spatial data and CCD sensor for texture data of the surface. A sensor system is developed for this
