....constraint from which the plane at in nity can be found. The key observation of this work is that for the plane at in nity the associated homography is conjugated to a rotation and therefore its eigenvalues have all of them the same modulus. Other approaches to self calibration can be found in [4] and [6] Another natural geometric object attached to a pair of identically calibrated cameras is the horopter curve, de ned as the set of points in space which have the same image coordinates in both cameras, and in general is a twisted cubic. They were introduced in modern computer vision by ....

....external 3D data as those provided by a precision calibration device. Self calibration of vision sensors has been actively researched in the last decade. However, most of the available methods were developed for calibration of passive vision systems such as stereo vision and depthfrom motion [4 11]. For active vision systems using structured light, the existing calibration methods are mostly based on static and manual operations. The available camera self calibration methods cannot be applied directly to structured light systems as they need more than two views for the calibration. ....

Chapter 2 The Geometry of Two Views This chapter deals with the geometric properties that arise when two cameras are looking at a scene, or equivalently one camera looking at a static scene from di#erent positions at di#erent times. The concepts presented here are adapted from [2, 6, 1]. The notation has been taken from [2] Symbols in boldface are used to denote vectors (like x,X) Symbols in Sans Serif denote matrices (line P,E) Many equations contain homogeneous entities where equality is only up to scale. Nevertheless, the = sign will be used. This chapter starts out with ....

....follows the former method ( 15] 7] 8] 4] 10] for the later we refer to [2] Since we are working with uncalibrated cameras, we choose an stratification approach to recover both camera parameters and structure of the scene. The idea is to upgrade from projective to Euclidean structure. In [6] a good review of different kind of methods is presented. The method presented in this paper allows to recover an Euclidean reconstruction of the model without any initial guess which is one of the drawbacks of most of the existing methods. Another important feature is that the whole process is ....
....we have P PH, then (M ) P (A B) 14) At this moment, we decouple the computation of the translation from the rotation one. This way, we will be able to compute the Euclidean reconstruction using essentially linear algorithms, instead of the nonlinear ones related with Kruppa s equations [6]. Taken into account that the shape matrix X is related to the geometry of the object and therefore, independent of the frame, we can express each point in local object coordinates X j = # # # j s xj # j s yj # j s zj # # ,j=1, n. 15) where s j = s xj ,s yj ,s zj ) are the local ....

Visual-Geometric Scene Reconstruction from Image Streams - Koch, Frahm (Correct)
....some of the calibration parameters must be set constant or known, as described before in section 2.1. A wealth on literature about self calibration has emerged over the last years. Starting with pioneering work by Hartley [11] and Faugeras [6] the problem has been investigated by numerous authors [14, 29, 8]. 369 4 The full 3 D case: Structure from Motion With all these information at hand we are able to devise a strategy for full 3 D reconstruction from image sequences. If a moving camera observes images of a rigid scene we can recover 3D scene structure and camera parameter from image ....

Heyden and Astr om [12] proved that it is sucient to know any of the ve intrinsic parameters to make Euclidean reconstruction, even ....
