Recovering Shape by Purposive Viewpoint AdjustmentKiriakos
We present an approach for recovering surface shape from the occluding contour using an active (i.e., moving) observer. It is based on a relation between the geometries of a surface in a scene and its occluding contour: If the viewing direction of the observer is along a principal direction for a surface point whose projection is on the contour , surface shape (i.e., curvature) at the surface p...
متن کاملObject Exploration by Purposive, Dynamic Viewpoint Adjustment
We present a viewing strategy for exploring the surface of an unknown object (i.e., making all of its points visible) by purposefully controlling the motion of an active observer. It is based on a simple relation between (1) the instantaneous direction of motion of the observer, (2) the visibility of points projecting to the occluding contour, and (3) the surface normal at those points: If the ...
متن کاملToward global surface reconstruction by purposive viewpoint adjustment
We consider the following problem: How should an observer change viewpoint in order to generate a dense image sequence of an arbitrary smooth surface so that it can be incrementally reconstructedusing the occluding contour and the epipolar parameterization? We present a collection of qualitative behaviors that, when integrated appropriately, purposefully control viewpoint based on the appearanc...
متن کاملBuilding Global Surface Models By Purposive and Qualitative Viewpoint Adjustment
We present an approach for recovering a global surface model of an object from the deformation of the occluding contour using an active (i.e., mobile) observer able to control its motion. In particular, we consider two problems: (1) How can the observer’s viewpoint be controlled in order to generate a dense sequence of images that allows incremental reconstruction of an unknown surface, and (2)...
متن کاملAffine Surface Reconstruction by Purposive Viewpoint Control
We present an approach for building an affine representation of an unknown curved object viewed under orthographic projection from images of its occluding contour. It is based on the observation that the projection of a point on a curved, featureless surface can be computed along a special viewing direction that does not belong to the point’s tangent plane. We show that by circumnavigating the ...
