Virtual City Models from Laser Altimeter and 2D Map

چکیده
Virtual reality applications in the context of urban planning presume the acquisition of 3D urban models. Photo realism can only be achieved, if the geometry of buildings is represented by a detailed and accurate CAD model and if additionally arti cial texture or real world imagery is mapped to the faces and roofs of the buildings. In the approach presented in this paper, height data provided by airborne laser scanning and existing ground plans of buildings are combined in order to enable an automatic 3D data capture. On demand the automatic building reconstruction can additionally be visually controlled and re ned by an interactive tool. Virtual reality city models are generated in the nal step by mapping terrestrial images to the facades of the reconstructed buildings. Thus the rapid acquisition of 3D urban GIS is feasible.

متن کاملGeneration and Update of 3D-City Models from Maps and Elevation Data
In this paper we describe a procedure for generating building models from large scale vector maps and laser altimeter data. First the vector map is analyzed. The result is used to mask the elevation data of single buildings and to derive a coarse 3D-description by prismatic models. Afterwards roofs are reconstructed by fitting planar surfaces to obtain a polyhedral model.
متن کاملGeneration of 3d-city Models and Their Utilisation in Image Sequences
In this paper we describe the construction of a city model and its support for the analysis of image sequences. Our city model consists of building models which were generated from large scale vector maps and laser altimeter data. First the vector map is analysed to group the outlines of buildings and to obtain a hierarchical description of buildings or building complexes. The base area of sing...
متن کاملSegmentation of Laser Altimeter Data for Building Reconstruction: Different Procedures and Comparison
One important step in the reconstruction of buildings from laser altimeter data is the segmentation step. In this contribution four procedures known from literature are investigated and compared. One procedure, which was made for detecting straight lines, which produces a segmentation as an intermediate result, was used. Three other procedures were installed, which are based on region growing. ...
متن کاملLaser Data for Virtual Landscape Generation
Within this article a procedure for the automatic generation of 3D city models is presented. For that purpose existing ground plans provided from a 2D GIS and height data measured by airborne laser scanning are combined. The presented approach can be applied for a fully automatic reconstruction of an urban model, for interactive control and correction of these automatically generated results an...
