Precise Target Geo-Location of Long-Range Oblique Reconnaissance System for UAVs [PDF]

Sensors, 2022
High-precision, real-time, and long-range target geo-location is crucial to UAV reconnaissance and target strikes. Traditional geo-location methods are highly dependent on the accuracies of GPS/INS and the target elevation, which restricts the target geo-

Vision-based Target Geo-location using a Fixed-wing Miniature Air Vehicle

Journal of Intelligent and Robotic Systems: Theory and Applications, 2006
This paper presents a method for determining the GPS location of a ground-based object when imaged from a fixed-wing miniature air vehicle (MAV). Using the pixel location of the target in an image, measurements of MAV position and attitude, and camera pose angles, the target is localized in world coordinates.

Visual odometry based absolute target geo-location from micro aerial vehicle [PDF]

2015 International Conference on Robotics, Automation, Control and Embedded Systems (RACE), 2015
An unmanned aerial system capable of finding world coordinates of a ground target is proposed here. The main focus here was to provide effective methodology to estimate ground target world coordinates using aerial images captured by the custom made micro aerial vehicle (MAV) as a part of visual odometery process on real time.
