- UAV-assisted navigation for insect traps in olive grovesPublication . Berger, Guido S.; Bonzatto Junior, Luciano; Pinto, Milena F.; Oliveira Júnior, Alexandre de; Mendes, João; Pereira, Ana I.; Silva, Yago M. R. da; Valente, António; Lima, JoséUnmanned Aerial Vehicles (UAVs) have emerged as valuable tools in precision agriculture due to their ability to provide timely and detailed information over large agricultural areas. In this sense, this work aims to evaluate the semi-autonomous navigation capacity of a multirotor UAV when applied in the field of precision agriculture. For this, a small aircraft is used to identify and track a set of fiducial markers (Ar Track Alvar) in an environment that simulates inspections of insect traps in olive groves. The purpose of this marker is to provide a visual reference point for the drone’s navigation system. Once the Ar Track Alvar marker is detected, the robot will receive navigation information based on the marker’s position to approach the specific trap. The experimental setup evaluated the computer vision algorithm applied to the UAV to make it recognize the Ar Track Alvar marker and then reach the trap efficiently. Experimental tests were conducted in a indoor and outdoor environment using DJI Tello. The results demonstrated the feasibility of applying these fiducial markers as a solution for the UAV’s navigation in this proposed scenario.
