Abstract

Disclosed is a method for generating a multi-resolution three-dimensional model, and for extracting feature lines using texture images and geometric data from a three-dimensional model. First, contours are detected for texture images using an image processing on the texture-mapped three-dimensional mesh data. With respect to geometric data, a discrete curvature is measured. The geometric data is parametrized into parameters in a two-dimensional domain, and contour images are detected using an image processing. The detected two contour images are generated into one model map, which is then reversely mapped to a reverse three-dimensional model, then next feature lines are extracted. Accordingly, a multi-resolution three-dimensional model can be generated while maintaining the extracted feature lines.
