Robust structure from motion using motion parallax
We present an efficient and geometrically intuitive algorithm to reliably interpret the image velocities of moving objects in 3D. It is well known that under weak perspective the image motion of points on a plane can be characterised by an affine transformation. We show that the relative image motion of a nearby noncoplanar point and its projection on the plane is equivalent to motion parallax ...
متن کاملNon-Rigid Shape-from-Motion for Isometric Surfaces using Infinitesimal Planarity
This paper proposes a general framework to solve Non-Rigid Shape-from-Motion (NRSfM) with the perspective camera under isometric deformations. Contrary to the usual low-rank linear shape basis, isometry allows us to recover complex shape deformations from a sparse set of images. Existing methods suffer from ambiguities and may be very expensive to solve. We bring four main contributions. First,...
متن کاملRobust Incremental Structure from Motion
We present a novel method to solve structure and motion problems robustly and incrementally from unordered sets of input images. The proposed method can build large reconstructions without depending on global structure for outlier rejection and starts from the most reliable parts of the data sets. The two main ideas are a strategy to identify reliable subsets of images that have the highest mut...
متن کاملRobust Invariants From Functionally Constrained Motion
We address in the problem of control-based recovery of robot pose and the environmental lay-out. Panoramic sensors provide us with an 1D projection of characteristic features of a 2D operation map. Trajectories of these projections contain the information about the position of a priori unknown landmarks in the environment. We introduce here the notion of spatiotemporal signatures of projection ...
متن کاملMotion Tracking System for Robust Non-Contact Blood Perfusion Sensor
We propose a motion-robust laser Doppler flowmetry (LDF) system that can be used as a non-contact blood perfusion sensor for medical diagnosis. Endoscopic LDF systems are typically limited in their usefulness in clinical contexts by the need for the natural organs to be immobilized, as serious motion artifacts due to the axial surface displacement can interfere with blood perfusion measurements...
