Abstract :
We deal with 3D object modeling using generalized cylinders from a single range image. We focus on right generalized cylinders, a class of generalized cylinders for which the cross-section is at right angle with the axis. No homogeneity or straightness constraints are imposed. The crucial part of this work is the extraction of axis points and the representation of the axis curve in 3D space. Interesting results are obtained with a broad variety of range images
