Description |
The proliferation of unmanned aircraft systems (UAS) has contributed to the asymmetric threat of malevolent actors exploiting this technology for mischief or harm. Existing ground-based solutions are limited by line of sight, while human-operated responder drones can be less responsive and more labor-intensive. Hence, there is a capability requirement for autonomous vision-based pursuit and interception of unauthorized drones. To address this, the author developed a computer vision (CV) algorithm to detect, track and estimate the relative position and range of a hovering and moving airborne small UAS target in field conditions. CV-based measurements were compared against GPS data, to assess the range and angular estimation performance of the CV algorithm. Then, the CV-estimated range and angular information was processed by a flight control algorithm utilizing simple angular guidance principle to pursue and intercept the target. Field tests of the algorithm were done using a prototype drone. This research will inform the conceptual design and choice of hardware implementation for a commercial-off-the-shelf-based counter-UAS capability. More broadly, the research contributes to the body of knowledge in autonomous object tracking applications. Subjects: computer vision; object detection; object tracking; position estimation; navigation; trajectory; UAS; drone |
