Stereo from uncalibrated cameras

چکیده
This paper considers the problem of computing placement of points in 3 dimensional space given two uncalibrated perspective views. The main theorem shows that the placement of the points is determined only up to an arbitrary projective transformation of 3-space. Given additional ground control points, however, the location of the points and the camera parameters may be determined. The method is linear and non-iterative whereas previously known methods for solving the camera calibration and placement to take proper account of both ground-control points and image correspondences are unsatisfactory in requiring either iterative methods or model restrictions. As a result of the main theorem, it is possible to determine projective invariants of 3-D geometric configurations from two perspective views.

Effective and efficient 3D object location using automatic camera calibration
Locating an object is an essential work in a robot system. In this paper, we present a method designed for the effective and efficient object location using the stereo vision. The 2D image information from the uncalibrated stereo cameras is used firstly to control the robot hand to approach the target object. Subsequently, the cameras are calibrated automatically using the information from the ...
متن کاملVisually guided grasping in unstructured environments
We present simple and robust algorithms which use uncalibrated stereo vision to enable a robot manipulator to locate, reach and grasp unmodelled objects in unstructured environments. In the rst stage, an operator indicates the object to be grasped by simply pointing at it. Next, the vision system segments the indicated object from the background, and plans a suitable grasp strategy. Finally, th...
متن کاملPath planning with uncalibrated stereo rig for image-based visual servoing under large pose discrepancy
Although image-based visual servoing provides superior performance in many vision-based robotic applications, it reveals fatal limitations when initial pose discrepancy is large. The feature points may leave the camera’s field of view, and also, the robot may not converge to the goal configuration. In this paper, a novel approach is proposed to resolve these limitations by planning trajectories...
متن کاملTrinocular Rectification for Various Camera Setups
Convergent stereo images can be rectified such that they correspond to the stereo normal case. The important advantage is that the correspondence analysis is simplified to a linear search along one of the image axes. The proposed method describes a rectification method for three uncalibrated cameras, where the configuration is not generally known. The algorithm automatically determines the best...
متن کاملUncalibrated Photometric Stereo
Lambertian photometric stereo with uncalibrated light directions and intensities determines the surface normals only up to an invertible linear transformation. We show that if object reflectance is a sum of Lambertian and specular terms, the ambiguity reduces into a 2dof group of transformations (compositions of isotropic scaling, rotation around the viewing vector, and change in coordinate fra...
متن کاملAutomatic Construction of Real-World Datasets for 3D Object Localization using Two Cameras
Unlike classification, position labels cannot be assigned manually by humans. For this reason, generating supervision for precise object localization is a hard task. This paper details a method to create large datasets for 3D object localization, with real world images, using an industrial robot to generate position labels. By knowledge of the geometry of the robot, we are able to automatically...
