نویسنده
چکیده
The advantages of vision-guided robots are widely recognized in industry and any improvement in the field has a lagre practical impact. First, we present state of the art in globally optimal algorithms in computer vision. The main mathematical aproaches that can be noticed in the field are discussed: polynomial methods, quasi-convex optimization, branch-and-bound algorithm and convex relaxation schemes. Next, we review the problem of camera-robot calibration. The Hand-Eye and Robot-World calibrations are presented and the problem of vision-aided calibration is formulated. The main goal of the thesis is to apply and augment the methods of computer vision in the field of vision-aided robotics and to present a practical global optimization technique for vision-aided robot calibration.

Planning, Localization, and Mapping for a Mobile Robot in a Camera Network
Networks of cameras such as building security systems can be a source of localization information for a mobile robot assuming a map of camera locations as well as calibration information for each camera is available. This thesis describes an automated system to acquire such information. A fully automated camera calibration system uses fiducial markers and a mobile robot in order to drastically ...
متن کاملEstimation and Calibration of Robot Link Parameters with Intelligent Techniques
Abstract: Using robot manipulators for high accuracy applications require precise value of the kinematics parameters. Since measurement of kinematics parameters are usually associated with errors and accurate measurement of them is an expensive task, automatic calibration of robot link parameters makes the task of kinematics parameters determination much easier. In this paper a simple and easy ...

Our research is based on Small Robot League of RoboCup, where a global vision system is applied to track eleven moving objects. To obtain the precise motion information of one ball and ten robots, two kinds of calibration are really important: the color calibration and the camera calibration. This paper investigates a K-Meanclustering-based color calibration algorithm to obtain accurate color i...
متن کاملSelf Calibration Without Minimization
Camera calibration is a necessary step in performing 3D scene reconstruction from photographic images. In this paper we present a new algorithm for the metric self calibration of a general pinhole camera that does not require the global minimization of an objective function and can produce all legal solutions to the three-camera self-calibration problem in a single pass. In contrast, virtually ...
متن کاملUnwarping Images of Curved Documents Using Global Shape Optimization
The unwarping of curved document images is a crucial problem for camera-based document analysis since most of current OCR techniques can not handle distortion due to perspective and warping. In previous work we have shown how to recover the page shape from a single image using an iterative procedure without camera calibration, and using the shape information to restore a frontal view of a flat ...
