Ferguson patch based method for representation of 3-D scenes

The need for 3-D computer vision in robot control, measurement of object geometry and autonomous vehicle navigation is clear. Many current 3-D schemes rely on algebraic surface representation methods. This paper presents a parametric surface representation method based on the Ferguson surface patch. A parametric representation method appears to be better for describing free form surfaces than algebraic methods. This kind of method may also advance the integration of CAD/CAM and computer vision.
