Critical Motion Sequences and Conjugacy of Ambiguous Euclidean Reconstructions
نویسنده
چکیده
This paper deals with critical motion sequences, i.e. sequences of camera motions that lead to inherent ambiguities in uncalibrated Euclidean reconstruction or self-calibration. Concretely, we focus on how to deal with ambiguous reconstructions. We show that the ambiguous Euclidean reconstructions from a critical motion sequence are conjugated in a special sense. We discuss how these conjugacies may be used to identify all ambiguous Euclidean reconstructions, even if there are discrete solutions or disjoint families of solutions.

Do Ambiguous Reconstructions Always Give Ambiguous Images?
In many cases self-calibration is not able to yield a unique solution for the 3D reconstruction of a scene. This is due to the occurrence of critical motion sequences. If this is the case, an ambiguity is left on the reconstruction. In this paper it is derived under which conditions correct novel views can be generated from ambiguous reconstructions. The problem is first approached from a theor...
متن کاملCritical Motions in Euclidean Structure from Motion
We investigate the motions that lead to ambiguous Euclidean scene reconstructions under several common calibration constraints, giving a complete description of such critical motions for: (i) internally calibrated orthographic and perspective cameras; (ii) in two images, for cameras with unknown focal lengths, either different or equal. One aim of the work was to evaluate the potential of moder...
متن کاملNon-rigid Self-calibration of a Projective Camera
Rigid structure-from-motion (SfM) usually consists of two steps: First, a projective reconstruction is computed which is then upgraded to Euclidean structure and motion in a subsequent step. Reliable algorithms exist for both problems. In the case of non-rigid SfM, on the other hand, especially the Euclidean upgrading has turned out to be difficult. A few algorithms have been proposed for upgra...
متن کاملCritical Motion Sequences for Monocular Self-Calibration and Uncalibrated Euclidean Reconstruction
In this paper, sequences of camera motions that lead to inherent ambiguities in uncalibrated Euclidean reconstruction or self-calibration are studied. Our main contribution is a complete, detailed classification of these critical motion sequences (CMS). The practically important classes are identified and their degrees of ambiguity are derived. We also discuss some practical issues, especially ...
متن کاملSome Issues on Self-Calibration and Critical Motion Sequences
This paper is concerned with the problem of selfcalibration. First some general concepts are discussed, then several methods are briefly discussed. In the second part of the paper the problem of critical motion sequences is treated. This problem could cause an important limitation to the practical use of self-calibration. In this context several interesting results are presented. self-calibrati...
