Affine and Projective Structure from Motion
نویسندگان
چکیده
We demonstrate the recovery of 3D structure from multiple images, without attempting to determine the motion between views. The structure is recovered up to a transformation by a 3D linear group the affine and projective group. The recovery does not require knowledge of camera intrinsic parameters or camera motion. Three methods for recovering such structure based on point correspondences are described and evaluated. The accuracy of recovered structure is assessed by measuring its invariants to the linear transformation, and by predicting image projections.

Navigation using Affine Structure from Motion
A structure from motion algorithm is described which recovers structure and camera position, modulo a projective ambiguity. Camera calibration is not required, and camera parameters such as focal length can be altered freely during motion. Unlike recent schemes which compute projective or affine structure using a batch process, the structure is updated sequentially over an image sequence. A spe...
متن کاملA Comparison of Viewing Geometries for Augmented Reality
Recently modern non-Euclidean structure and motion estimation methods have been incorporated into augmented reality scene tracking and virtual object registration. We present a study of how the choice of projective, affine or Euclidean scene viewing geometry and similarity, affine or homography based object registration affects how accurately a virtual object can be overlaid in scene video from...
متن کاملUncalibrated 1D projective camera and 3D affine reconstruction of lines
We describe a linear algorithm to recover 3D affine shape/motion from line correspondences over three views with uncalibrated affine cameras. The key idea is the introduction of a one-dimensional projective camera. This converts the 3D affine reconstruction of “lines” into 2D projective reconstruction of “points”. Using the full tensorial representation of three uncalibrated 1D views, we prove ...
متن کاملAffine Structure from Translational Motion in Image Sequences
In this paper a method for obtaining affine structure from an image sequence taken by a translating camera with constant intrinsic parameters is presented. A general geometric constraint, expressed using the camera matrices, is derived and this constraint is used in a least squares solution of the problem. The first step is to obtain a projective reconstruction, in the form of a sequence of cam...
متن کاملStructure from Motion from Three Affine Views
We describe a new method for Structure From Motion from three affine views. The central idea of the method is to explore the intrinsic three-view properties instead of previous two-view ones. The first key observation is that an affine camera is indeed essentially a one-dimensional projective camera operating on the plane at infinity : we prove that the essential motion—relative camera orientat...
