Problem
Self-outdoor localization of Unmanned Aerial Vehicles (UAVs) lacks accuracy, particularly, close to large structures (GPS-denied), close to metal structures (affecting compass accuracy), or under extreme weather or day/night conditions, impacting its self-navigation.
Current perception systems, such as LiDAR, visual or thermographic cameras and radar, fail under difficult environmental conditions (e.g., fog, glare, or darkness), impairing the effective autonomation of UAVs. Hence, accurate and precise navigation and perception systems are critical towards the full development of autonomous aerial drones and to mitigate air and ground risks.
Solution
A perception and navigation system easing precision landing and localization of (un)manned aerial vehicles, even in harsh light conditions.
Our solution is ArTuga (Augmented Reality Tag for Unmanned vision-Guided Aircraft), an innovative multimodal fiducial marker for aerial robotics and others, developed to improve the precision landing capability of unmanned aerial vehicles (UAVs) in harsh environments. This technology can also be applied to manned vehicles, as well as marine and land vehicles.
The technology consists of two main components – a multimodal fiducial marker (ArTuga), combining photometric and radiometric data, and a heterogeneous perception system (TriOPS) with a visual and thermal cameras and a LiDAR 3D – combined with a real-time multimodal fusion technique that ensures a robust and reliable detection of the target in severe environments.
ArTuga improves the situational awareness of the vehicles, increasing its detection capabilities and navigational abilities, especially in challenging lighting and weather conditions. Thus, improves UAVs autonomation and operations safety.
