This paper describes recent advances in autonomous visual landing of aircraft in three operational scenarios. The first suggests a robust visual target and an algorithm that tracks the suggested target. The second explores the case when we can not us

This paper describes a novel vision-based target tracking and landing method that uses aerial images from an on-board camera. The proposed method explicitly deals with occlusions that often occur during these maneuvers. Normalized cross correlation (

This paper proposes a novel method for corresponding visual measurements to map points in a visual-inertial navigation system. The algorithm is based on the minimization of the photometric error on sparse locations of the image region, and realizes a

An unmanned aerial vehicle requires adequate knowledge of its surroundings in order to operate in close proximity to obstacles. UAVs also have strict payload and power constraints which limit the number and variety of sensors available to gather this

GPS-denied closed-loop autonomous control of unstable Unmanned Aerial Vehicles (UAVs) such as rotorcraft using information from a monocular camera has been an open problem. Most proposed Vision aided Inertial Navigation Systems (V-INSs) have been too

Noncontact measurements of lightweight flexible aerospace structures present several challenges. Objects are usually mounted on a test stand, because current noncontact measurement techniques require that the net motion of the object be zero.However,
