Abstract

We propose an automatic modeling method that reconstructs three dimensional shape from range data called Z-map. Three dimensional CAD and CG application needs many procedure to define a three dimensional shape in a computer. Today, three dimensional image capturing techniques have progressed. It is easy to get Z-map data with these techniques. Z-map data is not a three dimensional shape but a group of points that represents distance form viewing point to a real object. It will be very convenient, in some applications, if we can transform the Z-map data into three dimensional shape data. The reconstruction method that we propose in this paper has robustness because Hough transformation is applied to its main process.
