Publisher Summary This chapter describes the structure from motion. The changing images resulting from relative motion between an observer and surfaces in the environment constitute an important source of information about the shapes, orientations, and relative distances of these surfaces.

Recursive Structure from Motion
2017In this paper we present a technique that estimates the Structure from Motion (SFM) in a recursive fashion. Traditionally successful SFM algorithms take the set of images and estimate the scene geometry and camera positions either using incremental algorithms or the global algorithms and do the refinement process [2] to reduce the reprojection error ...

This chapter is concerned with robust 3D scene modeling using a novel Structure from Motion algorithm - Direct Pose Registration Structure from Motion (DPR-SfM). The aim is to obtain a high precision texture model of a generic scene acquired using any off the shelf camera undergoing an arbitrary trajectory. The reconstruction algorithm does not require

Abstract : Work on improving gradient-based methods for optical flow estimation has been completed. An understanding of how errors arise makes it possible to define the inherent limitations of the gradient-based technique, obtain estimates of the accuracy of computed values, enhance the performance of the technique, and demonstrate the informative ...

Multibody Structure-from-Motion in Practice
IEEE Transactions on Pattern Analysis and Machine Intelligence, 2010Multibody structure from motion (SfM) is the extension of classical SfM to dynamic scenes with multiple rigidly moving objects. Recent research has unveiled some of the mathematical foundations of the problem, but a practical algorithm which can handle realistic sequences is still missing.

Resampling Structure from Motion
2010This paper proposes a hierarchical framework that resamples 3D reconstructed points to reduce computation cost on time and memory for very large-scale Structure from Motion. The goal is to maintain accuracy and stability similar for different resample rates.

Polynomial Methods For Structure From Motion
[1988 Proceedings] Second International Conference on Computer Vision, 1990The authors analyze the limitations of structure from motion (SFM) methods presented in the literature and propose the use of a polynomial system of equations, with the unit quaternions representing rotation, to recover SFM under perspective projection.

Size Constancy in Structure from Motion
Perception, 1995The relative motions of points in a structure-from-motion display involving parallel projection provide depth information in an object-centered framework: differences in velocity do not reflect differences in distance from an eyepoint. In contrast, size constancy is generally regarded to be a perspective effect, based on the relationship between ...
