Live demonstration: On the distance estimation of moving targets with a Stereo-Vision AER system

Abstract

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.
