Comunicación presentada al "ISCAS 2012" celebrado en Seúl (Corea del Sur) del 20 al 23 de Mayo del 2012. ; Distance calculation is always one of the most important goals in a digital stereoscopic vision system. In an AER system this goal is very important too, but it cannot be calculated as accurately as we would like. This demonstration shows a first approximation in this field, using a disparity algorithm between both retinas. The system can make a distance approach about a moving object, more specifically, a qualitative estimation. Taking into account the stereo vision system features, the previous retina positioning and the very important Hold and Fire building block, we are able to make a correlation between the spike rate of the disparity and the distance. ; This work has been supported by the Spanish government granted project VULCANO (TEC2009-10639-C04-02) of the MICINN. ; Peer Reviewed

et al. ; This paper describes CAVIAR, a massively parallel hardware implementation of a spike-based sensing-processing-learning-actuating system inspired by the physiology of the nervous system. CAVIAR uses the asychronous address-event representation (AER) communication framework and was developed in the context of a European Union funded project. It has four custom mixed-signal AER chips, five custom digital AER interface components, 45k neurons (spiking cells), up to 5M synapses, performs 12G synaptic operations per second, and achieves millisecond object recognition and tracking latencies. © 2009 IEEE. ; This work was supported by the European Commission under Grant IST-2001-34124 (CAVIAR).
