Handling Missing Data in the Computation of 3D Affine Transformations
The reconstruction of rigid scenes from multiple images is a central topic in computer vision. Approaches merging partial 3D models in a hierarchical manner have proven the most effective to deal with large image sequences. One of the key building blocks of these hierarchical approaches is the alignment of two partial 3D models, which requires to express them in the same 3D coordinate frame by ...
متن کاملUtilizing non-iterative linear transformations between non-uniformly dilated 3D frames
Linear transformations have been routinely applied in various field applications since they permit a straightforward geometric relationship between different coordinate systems. The most general form of linear transformations which is also referred to as the affine model allows coordinate transformations between non-uniformly dilated systems. This particular model is intrinsically useful for da...

متن کاملAffine Invariant Descriptors of 3d Object Using Multiple Regression Model
In this work, a new method invariant [1,2,3] for 3D object is proposed using multiple regression model. This method consists of extracting an invariant vector using the multiple linear parameters model applied to the 3D object, it’s invariant against affine transformation of this object. The concerned 3D objects are transformations of 3D objects by one element of the overall transformation. The...
متن کاملGauge Invariance in Projective 3D Reconstruction
Bundle adjustment is a standard photogrammetric technique for optimizing the 3D reconstruction of a scene from multiple images. There is an inherent gauge (coordinate frame) ambiguity in 3D reconstruction that can seriously affect the convergence of bundle adjustment algorithms. We address this issue and show that a simple pre-conditioning step removes the effect of the choice of coordinate fra...
