摘要: This article proposes a novel visual framework for detecting tunnel crossings/junctions in underground mine areas towards the autonomous navigation of Micro Aerial Vehicles (MAVs). Usually environments have complex geometries, including multiple crossings with different tunnels that challenge planning aerial robots. Towards envisioned scenario or semi-autonomous deployment MAVs limited Line-of-Sight subterranean environments, proposed module acknowledges existence junctions by providing crucial information to autonomy and layers vehicle. The capability junction detection is necessary majority mission scenarios, unknown area exploration, known inspection robot homing missions. method has ability feed image stream from vehicles on-board forward facing camera Convolutional Neural Network (CNN) classification architecture, expressed four categories: 1) left junction, 2) right 3) & 4) no local vicinity core contribution stems incorporation AlexNet transfer learning scheme branches environment. validity been validated through data-sets collected real demonstrating performance merits module.
