چکیده

Camera calibration is essential to many computer vision applications. Most existing calibration algorithms in the literature consist of estimating both intrinsic and extrinsic camera parameters through non-linear iterative minimizations using only point features. We show that using lines and planes in a consistant framework allows to rst entirely decouple intrinsic and extrinsic camera parameters, and then extract closed form solutions for them making optimal use of the geometrical constraints existing in the scene. We introduce a new formalism, which we calìdual space', that allows one to represent cleanly and intuitively many useful geometrical relashionships between planes, lines and points in space, and lines and points on the image plane. Calibration results are presented on real images retrieved from a standard image database.

From Ordinal to Euclidean Reconstruction with Partial Scene Calibration

Since uncalibrated images permit only projective reconstruction, metric information requires either camera or scene calibration. We propose a stratified approach to projective reconstruction, in which gradual increase in domain information for scene calibration leads to gradual increase in 3D information. Our scheme includes the following steps: (1) Register the images with respect to a referen...

3d Aspects of 2d Epipolar Geometry

Relative orientation in a stereo pair (establishing 3D epipolar geometry) is generally described as a rigid body transformation, with one arbitrary translation component, between two formed bundles of rays. In the uncalibrated case, however, only the 2D projective pencils of epipolar lines can be established from simple image point homologies. These may be related to each other in infinite vari...

3D Voxel Construction Based on Epipolar Geometry

In this paper, we propose an approach for construction of a projective 3D voxel space based on epipolar geometry obtained with weak calibration. This concept of voxel space defines the epipolar lines following to the coordinate axis. In the field of computer vision, it is common to reconstruct 3D geometry data based on camera calibration data and disparities of matching points in each image. In...

Accurate Camera Calibration with simplified Patterns with a Self-calibration Approach

In this paper we present a unified approach for calibration and self-calibration of multi-camera systems. The technique is based on an algorithm for the resolution of the self-calibration problem, with which it is possible to find the camera geometry up to an arbitrary perspective transformation of the calibrated scene space. The correct geometry is then obtained by properly exploiting the dime...

A New Approach for Vanishing Line Estimation

In photogrammetry and computer vision, retrieving object space information from images remains a fundamental task and numerous efforts have been dedicated to this specific topic. It is revealed in recent research papers that vanishing points and vanishing lines provide clues about the structures of the object space. A variety of approaches have been proposed either for single-camera systems or ...
