Paper Abstract

An airborne vehicle must avoid obstacles like towers, fences, tree branches, mountains and building across the flight path. So the ability to detect and locate obstacles using on-board sensors is an essential step in the autonomous navigation of aircraft low-altitude flight. In this paper, a novel passive range method using conditional random field (CRF) is presented to map the 3D scene in front of a moving aircraft with image sequences obtained from a forward-looking imaging sensor. Finally, An dynamic graph cuts method was presented for the CRF model to recursively update thedepth map. Experimental data demonstrates the effectiveness of our approach.
