Three-view camera calibration using geometric algebra

چکیده
In a former work of ours [I], we proposed a new way to express and interpret the epipolar constraint using Geometric Algebra, and we derived from it a novel and efficient 2view camera calibration technique. In this paper we extend this GA approach to the 3-view case. Aiter expressing the trifocal constraint in t e m of bivectors and trivectors, we provide an altemative geometric interpretation of the coefficients of the trifocal tensor. On the basis of that, we propose a novel solution for the simultaneous determination of the focal lengths of the cameras and the rigid motion between three views.

Cone of view camera model using conformal geometric algebra for classic and panoramic image sensors
Camera calibration is a necessary step in 3D computer vision in order to extract metric information from 2D images. Calibration has been defined as the non parametric association of a projection ray in 3D to every pixel in an image. It is normally neglected that pixels have a finite surface that can be approximated by a cone of view that has the usual ray of view of the pixel as a directrix axi...
متن کاملNew perspectives on camera calibration using geometric algebra
In this paper we propose a new approach to the camera self-calibration problem, based on geometric algebra. After a brief introduction on the adopted Clifford algebra framework, we provide new insight on the epipolar constraint as defined in terms of bivectors. On the basis of that, we propose a novel solution for the simultanous determination of the focal lengths of the cameras and the rigid m...

On-orbit geometric calibration is a key technology to guarantee the geometric quality of high-resolution optical satellite imagery. In this paper, we present an approach for the on-orbit geometric calibration of high-resolution optical satellite imagery, focusing on two core problems: constructing an on-orbit geometric calibration model and proposing a robust calculation method. First, a rigoro...
متن کاملA Simple Method of Multiple Camera Calibration for the Joint Top View Projection
A simple method for multiple camera calibration based on a novel geometric derivation is presented. The main advantage of this method is that it uses only three points in the world coordinate system to achieve the calibration. Rotation matrix and translation vector for each camera coordinate system are obtained via the given distance between the vertices of the marker triangle formed by the thr...
متن کاملComputing the Intrinsic Camera Parameters Using Pascal's Theorem
The authors of this paper adopted the characteristics of the image of the absolute conic in terms of Pascal's theorem to propose a new camera calibration method. Employing this theorem in the geometric algebra framework enables the authors to compute a projective invariant using the conics of only two images which expressed using brackets helps us to set enough equations to solve the calibratio...
