Viewpoint-Invariant Reconstruction of Visible Surfaces
نویسندگان
چکیده
Stereoscopic VISIon delivers a sparse map of the range to various "matched" points or contours, in the field of view. This paper addresses the problem of explicitly reconstructing a smooth surface that interpolates those points and contours. It is argued that any scheme for surface reconstruction should be viewpoint-invariant; otherwise the reconstructed surface would "wobble" as the viewpoint changes. Progress has been made towards obtaining viewpointinvariant reconstruction. A scheme has been implemented in 2-D and found to be relatively invariant to changes of viewpoint. Some remaining theoretical problems are outlined.

Discontinuity-Preserving and Viewpoint Invariant Reconstruction of Visible Surfaces Using a First Order Regularization
This paper describes the application of a first order regularization technique to the problem of reconstruction of visible surfaces. Our approach is a computationally efficient first order method that simultaneously achieves approximate in\ nriance and preservation of discontinuities. Our reconstruction method is also robust with respect to the smoothing parameter The robustness property to I a...
متن کاملReconstructing a Visible Surface
We address the problem of reconstructing the visible surface in stereoscopic vision. We point out the need for viewpoint invariance in the reconstruction scheme and demonstrate the undesirable "wobble" effect that can occur when such invariance is lacking. The design of an invariant scheme is discussed.
متن کاملCoordinate finite type invariant surfaces in Sol spaces
In the present paper, we study surfaces invariant under the 1-parameter subgroup in Sol space $rm Sol_3$. Also, we characterize the surfaces in $rm Sol_3$ whose coordinate functions of an immersion of the surface are eigenfunctions of the Laplacian $Delta$ of the surface.

This paper presents a new planning approach of generating unknown 3-D models automatically. The new algorithm incorporates the limit visual surfaces with the trend surfaces and selects the suitability of viewpoints as the NBV on scanning coverage. The limit visual surfaces and trend surfaces are modelled by means of the known boundary region data obtained from initial view. The optimal design m...
متن کاملTranslation invariant surfaces in the 3-dimensional Heisenberg group
In this paper, we study translation invariant surfaces in the 3-dimensional Heisenberg group $rm Nil_3$. In particular, we completely classify translation invariant surfaces in $rm Nil_3$ whose position vector $x$ satisfies the equation $Delta x = Ax$, where $Delta$ is the Laplacian operator of the surface and $A$ is a $3 times 3$-real matrix.
