RT Journal Article T1 Error Reduction in Vision-Based Multirotor Landing System A1 Llerena Caña, Juan Pedro A1 García Herrero, Jesús A1 Molina López, José Manuel AB New applications are continuously appearing with drones as protagonists, but all ofthem share an essential critical maneuver—landing. New application requirements have led thestudy of novel landing strategies, in which vision systems have played and continue to play akey role. Generally, the new applications use the control and navigation systems embedded in theaircraft. However, the internal dynamics of these systems, initially focused on other tasks such as thesmoothing trajectories between different waypoints, can trigger undesired behaviors. In this paper,we propose a landing system based on monocular vision and navigation information to estimate thehelipad global position. In addition, the global estimation system includes a position error correctionmodule by cylinder space transformation and a filtering system with a sliding window. To conclude,the landing system is evaluated with three quality metrics, showing how the proposed correctionsystem together with stationary filtering improves the raw landing system.
