Visual Servoing in Unconventional Environments |
 |
Abstract:
Most robotic vision algorithms are proposed by
envisaging robots operating in structured environments where
the world is assumed to be rigid. These algorithms fail to
provide optimum behavior when the robot has to be controlled
with respect to active non-rigid targets. This work presents
a new framework for visual servoing that accomplishes the
robot positioning task even in non-rigid environments. We
introduce a space-time representation scheme for modeling the
deformations of a non-rigid object and propose a model-free
hybrid approach that exploits the two-view geometry induced
by the space-time features to perform the servoing task. Our
formulation can address a variety of non-rigid motions and
can tackle large camera displacements without being affected
by the degeneracies in the task space. Experimental results
validate our approach and demonstrate the robust and stable
behavior.
