An important issue in realizing robots with stereo vision is the efficient control of the vergence angle. In an active robotic vision system the vergence angle along with the pan and tilt ones determines uniquely the fixation point in the 3D space. The vergence control involves the adjustment of the angle between the two cameras' axes towards the fixation(More)
A novel digital image stabilization technique is proposed in this paper. It is based on a fuzzy Kalman compensation of the global motion vector (GMV), which is estimated in the log-polar plane. The GMV is extracted using four local motion vectors (LMVs) computed on respective subimages in the logpolar plane. The fuzzy Kalman system consists of a fuzzy(More)
—The pose estimation from visual sensors is widely practiced nowadays. The pose vector is estimated by means of homographies and projection geometry. The integration of visual and inertial measurements is getting more attractive due to its robustness and flexibility. The cooperation of visual with inertial sensors for finding a robot's pose bears many(More)
The ACROBOTER project aims to develop a radically new locomotion technology that can effectively be used in a home and/or in a workplace environment for manipulating small objects autonomously. It extends the workspace of existing indoor service robots in the vertical direction, whilst its novel structure allows covering the whole volume of a room. For the(More)
Digital image stabilization (DIS) is the process that compensates the undesired fluctuations of a frame's position in an image sequence by means of digital image processing techniques. DIS techniques usually comprise two successive units. The first one estimates the motion and the successive one compensates it. In this paper, a novel digital image(More)
