Scene stitching with event-driven sensors on a robot head platform

This paper describes a robot head platform which holds a pair of event-based Dynamic Vision Sensor (DVS) retinas and microphones connected to an event-based binaural AEREAR2 VLSI cochlea system. The platform has 6 degrees of freedom (DOF): 2 for the neck, and 2 for each of the DVS retinas. Two applications using this platform are described: the first is image stitching of a scene larger than the field of view of the individual retinas as the head pans and tilts and the second is selective image painting of the local visual scene around spatially displaced sound sources. This platform allows for the investigation of event-driven sensory-action models that use the information from multiple event-based sensor modalities in real-time scenarios.
