  In this paper we describe the Open Vision Computer (OVC) which was designed
to support high speed, vision guided autonomous drone flight. In particular our
aim was to develop a system that would be suitable for relatively small-scale
flying platforms where size, weight, power consumption and computational
performance were all important considerations. This manuscript describes the
primary features of our OVC system and explains how they are used to support
fully autonomous indoor and outdoor exploration and navigation operations on
our Falcon 250 quadrotor platform.
