A Ground-Based Near Infrared Camera Array System for UAV Auto-Landing in GPS-Denied Environment
This paper proposes a novel infrared camera array guidance system with capability to track and provide real time position and speed of a fixed-wing Unmanned air vehicle (UAV) during a landing process. The system mainly include three novel parts: (1) Infrared camera array and near infrared laser lamp based cooperative long range optical imaging module; (2) Large scale outdoor camera array calibr...
متن کاملSelecting the Visual Landing Markers Located on a Ship Deck for UAV Automatic Landing
Of all the flight modes of unmanned aerial vehicles (UAVs), the landing approach and the landing itself are the most difficult and dangerous ones. To perform an automatic landing on a ship deck using a computer vision system (CVS), a UAV must analyze the visual landing markers located on the deck. When the UAV is about to start landing, these markers must be clearly visible and discernible. The...
متن کاملUAV Quadcopter Landing on a Displaced Target
Unmanned Aerial Vehicles (UAVs) are becoming more popular each year, and the applications they can be used for continue to grow as well. One issue faced by UAV quadcopters at the moment is autonomously landing accurately at a home base location that may have changed from its starting position. The solution proposed to this problem is using a GPS signal that gives the quadcopter the approximate ...
متن کاملDynamic Markers: UAV landing proof of concept
In this paper, we introduce a dynamic fiducial marker which can change its appearance according to the spatio-temporal requirements of the visual perception task of a mobile robot using a camera as sensor. We present a control scheme to dynamically change the appearance of the marker such that the pose of the robot can be optimally estimated from the camera image. The appearance control takes i...
متن کاملLocalization Framework for Real-Time UAV Autonomous Landing: An On-Ground Deployed Visual Approach
[-5]One of the greatest challenges for fixed-wing unmanned aircraft vehicles (UAVs) is safe landing. Hereafter, an on-ground deployed visual approach is developed in this paper. This approach is definitely suitable for landing within the global navigation satellite system (GNSS)-denied environments. As for applications, the deployed guidance system makes full use of the ground computing resourc...
