Distinguishing Malicious Drones Using Vision Transformer

Robust positioning of drones for land use monitoring in strong terrain relief using vision-based navigation

For land use monitoring, the main problems are robust positioning in urban canyons and strong terrain reliefs with the use of GPS system only. Indeed, satellite signal reflection and shielding in urban canyons and strong terrain relief results in problems with correct positioning. Using GNSS-RTK does not solve the problem completely because in some complex situations the whole satellite's syste...

Transformer protection using MLE approach

This paper proposed a new wavelet based method to identify inrush currents and to distinguish it from power system faults. The proposed algorithm extracts fault and inrush generated transient signals using DWT. Transient current signals at both sides of a transformer are firstly captured. The wavelet transform is a relatively new and powerful tool in the analysis of power transformer transient ...

Directing Cinematographic Drones

Quadrotor drones equipped with high quality cameras have rapidely raised as novel, cheap and stable devices for filmmakers. While professional drone pilots can create aesthetically pleasing videos in short time, the smooth – and cinematographic – control of a camera drone remains challenging for most users, despite recent tools that either automate part of the process or enable the manual desig...

Vision Based Navigation of Aerial Drones over The Rain Forest: Extracting and Tracking Natural Landmarks

There is a sort of important scenarios, such as long endurance missions, where an autonomous drone would be very effective. One of these scenarios of applications is the long term monitoring of the Amazon rain forest. The uniform pattern of the canopy defines a mission difficult to be performed by a human operator. In such situation, an embedded vision system capable to drive the vehicle while ...
