Projective Translations and Affine Stereo Calibration
نویسندگان
چکیده
This paper investigates the homography which transforms a set of points in projective space when undergoing a rigid translation, termed a projective translation. A representation with seven parameters is proposed. They represent explicitly the geometric entities constraining and defining the translation. A practical algebraic method for extracting these parameters is developed. It allows for affine calibration of a stereo rig, for characterizing the motion intrinsics, as well as for composing projective translations. The practical effectiveness of calibration is evaluated on synthetic and real image data.

Affine Stereo Calibration for Relative Affine Shape Reconstruction
It has been shown that relative projective shape, determined up to an unknown projective transformation, with respect to 5 reference points can be obtained from point-to-point correspondences of a pair of images; Affine shape up to an unknown affine transformation with respect to 4 points can be obtained from parallel projection. We show in this paper that afTine shape with respect to 4 referen...
متن کاملMaintaining stereo calibration by tracking image points
An important problem in active 3-D vision is updating the camera calibration matrix as the focus, aperture, zoom or vergence angle of the cameras changes dynamically. After an introduction we present a technique to compute the projection matrix from five and a half points in a scene without matrix inversion. We then present a technique for correcting the projective transformation matrix by trac...
متن کاملAffine stereo calibration
Affine stereo calibration has been identified as the determination of the plane collineation induced by the plane at infinity. Generally, this so-called infinity homography can be determined provided 3 image correspondences of points at infinity. In this paper, we are first concerned with affine stereo calibration for the case of two cameras with the same intrinsic parameters. It is shown that ...
متن کاملUncalibrated Stereo Hand-Eye Coordination
This paper describes a system that combines stereo vision with a 5-DOF robotic manipulator, to enable it to locate and reach for objects by sight. Our system uses an affine stereo algorithm, a simple but robust approximation to the geometry of stereo vision, to estimate positions and surface orientations. It can be calibrated very easily with just four reference points. These are defined by the...
متن کاملVisual Servoing of Robot Manipulators Part I: Projective Kinematics
Visual servoing of robot manipulators is a key technique where video images, i.e. the visual appearance of an object is used to control the end-e ector. Most such methods use robots and cameras that have been calibrated. In this report we suggest a non-metric formulation of visual servoing that works with an uncalibrated stereo rig, i.e. in the projective space associated with it. In consequenc...
