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&Fire building block, we are able to make a correlation
between the spike rate of the disparity and the distance.Ministerio de Ciencia e Innovación TEC2009-10639-C04-0
