Free-form object segmentation and representation from registered range and color images

摘要

This paper describes a new technique to 3D surface segmentation and representation of free-form objects from registered range and color images. The proposed approach combines edge and region information to derive a surface description using algebraic implicit surfaces. This is done by propagating and blending Piecewise Hermite Interpolation Surfaces. The proposed technique, not only reduces the number of used patches, but also preserves surface-depth and orientation continuity. It can also be used to generate partial surface models for CAD-based vision and object recognition purposes. Realistic partial models are obtained by mapping texture extracted from a registered color image onto the generated surfaces. Experimental results show that the system can produce reliable surface segmentation as well as realistic 3D surface models of free-form objects.
