چکیده

I. ABSTRACT A novel visual servoing method is presented. The algorithm works for both apparent contours and point features and does not require any information about the internal camera parameters. The proposed visual servoing is based on the epipolar geometry and exploits the autoepipolar property, a special configuration for the epipoles which occurs when the desired and current views undergo a pure translation. This occurrence is simply detectable from special line conditions on the overlapped current and desired images. Experiments are presented to validate the proposed visual servoing.

Image-based Visual Servoing with Central Catadioptric Cameras

This paper presents an image-based visual servoing strategy for the autonomous navigation of a mobile holonomic robot from a current toward a desired pose, specified only through a current and a desired image acquired by the on-board central catadioptric camera. This kind of vision sensor combines lenses and mirrors to enlarge the field of view. The proposed visual servoing does not need any me...

Epipole-based visual servoing for mobile robots

This paper proposes a visual servoing algorithm for mobile robot navigation based on the epipolar geometry retrieved by object profiles. The main motivation for this approach is that for unstructured scenes the task of solving correspondences is definitely a harder task than contour detection. An unstructured three-dimensional (3-D) scene consists mainly of objects whose most important 2-D feat...

Epipole-based Visual Servoing Using Profiles

This paper proposes a visual servoing algorithm for mobile robot navigation based on object profiles which is alternative to approaches based on point correspondences. Motivation to this research is that for unstructured scenes the task of solving correspondences is definitely a harder task than contour detection. An unstructured 3D scene exhibits only surfaces whose main 2D features are their ...

A Visual Servoing Algorithm Based on Epipolar Geometry

A visual servoing algorithm for mobile robots is proposed. The main feature of the algorithm is that it exploits object profiles rather than solving correspondence problems using object features or texture. This property is crucial for mobile robot navigation in unstructured environments where the 3D scene exhibits only surfaces whose main features are their apparent contours. The framework is ...

Sliding Mode Control for Visual Servoing of Mobile Robots using a Generic Camera

At present, vision sensors represent a very good option for the control of robots since they provide at a low cost a lot of information from the environment. The feasibility of using a vision system as the only source of feedback information has been shown by many approaches (Chaumette & Hutchinson (2006), Chaumette & Hutchinson (2007)). Particularly, incorporating machine vision for the contro...
