Navigation of UAV in GNSS denied area

Abstract

This paper examines the concept of navigation of of Unmanned aerial vehicle (UAV) in three-dimensional space using visual odometry. In the near future navigation of the UAV without GNSS is becoming a critical part of autonomous navigation systems, using information from on-board cameras to estimate the UAV’s movement and position. In the paper, different types of visual odometry, sensors for visual odometry, components of the implementation, and scenarios of usage. For the development and future application we utilize widely used Robotic Operating System (ROS).
