Event Abstract

Early perception-action cycles in binocular robot vision

  • 1 DIBE - University of Genoa, Italy

Traditionally, in robot vision systems, the perception-action loop closes at a "system level" (by decoupling de factothe vision modules from those dedicated for motor control and motor planning), and the exploitation of the computational effects of the eye movements on the visual processes are very seldom in artificial artifacts. On the contrary, a wide number of neurophysiological experiments report of modulatory effects of motor and premotor signals on the visual receptive fields across several cortical areas, postulating a role in gaining a visuospatial perception in head-centered coordinates, and for a mutual calibration of the vision and the arm systems in the peripersonal space. On this ground, there is a growing attention for moving the active vision paradigm from systems in which just the effects of action influence the perception, to systems where the acting itself, and even its planning, operate in parallel with perception, thus really closing the loops and taking full advantage of a concurrent/anticipatory perception-action processing. In this context, cortical-like architectures for both vergence control and depth perception that incorporate adaptive tuning mechanisms of the disparity detectors will be presented, as a part of a broader research framework in which adaptation will eventually depend on priors,related both to the posture of the eyes in the orbits and to the attentional signals that might guide intentional exploration of the selected object.
