چکیده
Paul Y. Oh and Peter K. Allen Dept. of Computer Science, Columbia University, New York, NY 10027 Abstract Image-based servoing systems are often used to track moving targets and their underlying control architecture is a regulation of the image. This regulation is a function of rigid camera-to-target geometric constraints. Satisfying such constraints requires that the robot motors have su cient velocity bandwidths, and often these bandwidths are limited. This paper lays down the foundation for a partitioned controller. Such a controller would coordinate a camera's DOF into a synergistic move to overcome bandwidth limitations. Tracking experiments are shown on a custom designed 5 DOF gantry robot which highlight the limitations of regulator-based control, as well as show how partitioning can be used to achieve more robust control.

Optimal Observer Path Planning For Bearings-Only Moving Targets Tracking Using Chebyshev Polynomials
In this paper, an optimization problem for the observer trajectory in the bearings-only surface moving target tracking (BOT) is studied. The BOT depends directly on the observability of the target's position in the target/observer geometry or the optimal observer maneuver. Therefore, the maximum lower band of the Fisher information matrix is opted as an independent criterion of the target estim...
متن کاملStatistical Background Modeling Based on Velocity and Orientation of Moving Objects
Background modeling is an important step in moving object detection and tracking. In this paper, we propose a new statistical approach in which, a sequence of frames are selected according to velocity and direction of some moving objects and then an initial background is modeled, based on the detection of gray pixel's value changes. To have used this sequence of frames, no estimator or distribu...
متن کاملIllusory bending of a pursuit target
To pursue a small target moving in front of a drifting background, motion vectors from the target need to be integrated and segmented from those belonging to the background. Smooth pursuit eye movements typically integrate target and background directions initially and after some time shift towards the veridical target direction. The perceived target direction on the other hand is generally sta...
متن کاملRadial bias for orientation and direction of motion modulates access to visual awareness during continuous flash suppression.
Two types of radial bias have been demonstrated in the primate visual cortex: for orientation and for direction of motion. Considering that a visual neuron's directional selectivity is generally perpendicular to its preferred orientation, it is counterintuitive that radial biases for orientation and direction of motion coexist in retinotopic cortex including primary visual cortex. The current s...
متن کاملVisual Target Motion Analysis Using Controlled Camera Motion
We describe a set of techniques whereby absolute position and velocity of a moving target can be obtained with the aid of a position controlled visual sensor. We investigate how the sensor trajectory can be optimized to reduce the sensitivity of the target parameter estimates to noise in the measurements. We present a discrete time technique for obtaining the depth and motion of a moving target...
