Active 3d Vision in a Humanoid Robot
Motion parallax, the relative motion of 3D space at different distances experienced by a moving agent, is one of the most informative cues. While motion parallax is typically investigated during navigation, it also occurs in most robotic head/eye systems during rotations of the cameras. In these systems, as in the eyes of many species, the optical nodal points do not lie on the axes of rotation...
متن کاملRobot Motion Vision Part II: Implementation
The idea of Fixation introduced a direct method for general recovery of shape and motion from images without using either feature correspondence or optical flow [1,2]. There are some parameters which have important effects on the performance of fixation method. However, the theory of fixation does not say anything about the autonomous and correct choice of those parameters. This paper presents ...
متن کاملMobile Robot Navigation Using Active Vision
Active cameras provide a navigating vehicle with the ability to fixate and track features over extended periods of time, and wide fields of view. While it is relatively straightforward to apply fixating vision to tactical, short-term navigation tasks, using serial fixation on a succession of features to provide global information for strategic navigation is more involved. However, active vision...
متن کاملMobile Robot Localisation Using Active Vision
Abstract. Active cameras provide a mobile robot with the capability to fixate and track features over a wide field of view. However, their use emphasises serial attention focussing on a succession of scene features, raising the question of how this should be best achieved to provide localisation information. This paper describes a fully automatic system, able to detect, store and track suitable...
متن کاملImage Stabilization in Active Robot Vision
Recent demands in sophisticated mobile robots require many semi-autonomous or even autonomous operations, such as decision making, simultaneous localization and mapping, motion tracking and risk assessment, while operating in dynamic environments. Most of these capabilities depend highly on the quality of the input from the cameras mounted on the mobile platforms and require fast processing tim...
