University of Missouri researchers are transforming the way drones operate by developing autonomous visual navigation capabilities that could prove crucial during natural disasters. These groundbreaking advancements hinge on the drones’ ability to navigate and interact with their environment independent of GPS technology.
Innovative AI algorithms are being designed to allow drones to autonomously navigate and complete complex tasks, particularly in environments where GPS reception is compromised. This has potential implications for military and rescue missions where GPS may be unreliable or unavailable.
University of Missouri students spent a month at the Yuma Proving Grounds in Arizona, one of the biggest military facilities globally, working on collecting raw video data using drones customized for both visible and infrared spectrum. This research is fundamental to a two-year project supported by the US Army Engineer Research and Development Center (ERDC), showcasing the significant backing of the defense department.
The ability to operate autonomously becomes critical in scenarios where GPS signals are disrupted, such as in natural disasters or military conditions. Kannappan Palaniappan, a prominent electrical engineering and computer science professor and the project lead, emphasizes that current drones primarily rely on GPS navigation and are at a significant disadvantage without it.
At present, drone pilots must manually navigate the unmanned aerial vehicle (UAV) while avoiding obstacles like buildings and other structures while staying within visual line of sight. Palaniappan’s team is working on software that would allow drones to self-navigate, making autonomous decisions based on environmental interaction and contextual scene understanding.
Advancing Intelligent Scene Perception with recent sensor technology like Light Detection and Ranging (LiDAR) and thermal imaging permits limited yet sophisticated tasks like object detection and visual identification. Combined with the team’s algorithms powered by deep learning and machine learning, drones could assist in developing sophisticated imagery for mapping and surveillance applications.
As humans utilize dynamic 3D models and movement patterns to understand their environment, Palaniappan mentions that they are now striving to incorporate these salient aspects of human vision into autonomous aerial and ground-based vision navigation algorithms.
Overcoming Technological Constraints such as the need for computing resources like processing power and memory is critical for advanced imagery capabilities. Addressing potential solutions, the MU-led team is investigating how to exploit cloud computing and high-performance edge computing for rapid analysis and the development of three-dimensional digital twin models without additional software on the drone itself.
The MU team, which includes Prasad Calyam, Filiz Bunyak, and Joshua Frazer, collaborates with researchers from the University of Saint Louis, the University of California-Berkeley, and the University of Florida, expanding the project’s scope and expertise.
