Motion Estimation via Dynamic Vision - Automatic Control, IEEE Transactions on
Abstruct-Zstimating the three-dimensional motion of an object from a sequence of projections is of paramount importance in a variety of applications in control and robotics, such as autonomous navigation, manipulation, servo, tracking, docking, planning, and surveillance. Although “visual motion estimation” is an old problem (the first formulations date back to the beginning of the century), on...
متن کاملDynamic Visual Motion Estimation
Visual motion is the projection of scene movements on a visual sensor. It is a rich source of information for the analysis of a visual scene. Especially for dynamic vision systems the estimation of visual motion is important because it allows to deduce the motion of objects as well as the self-motion of the system relative to the environment. Therefore, visual motion serves as a basic informati...
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 کاملThree - Dimensional Vision Forstructure and Motion Estimation
This thesis addresses computer vision techniques estimating geometric properties of the 3-D world from digital images. Such properties are essential for object recognition and classi cation, mobile robots navigation, reverse engineering and synthesis of virtual environments. In particular, this thesis describes the modules involved in the computation of the structure of a scene given some image...
متن کاملUAV Motion Estimation Using Hybrid Stereoscopic Vision
Motion and velocity are essential parameters for an Unmanned Aerial Vehicle (UAV) during critical maneuvers such as landing or take-off. In this paper, we present a hybrid stereoscopic rig made of a fisheye and a perspective cameras for motion estimation. The rotation and translation are estimated by a decoupling. The fisheye view contributes to determine the orientation and the attitude while ...
