Visual Localization with Google Earth Images for Robust Global Pose Estimation of UAVs

Bhavit Patel, Timothy D. Barfoot, Angela P. Schoellig

ICRA 2020poster

We estimate the global pose of a multirotor UAV by visually localizing images captured during a flight with Google Earth images pre-rendered from known poses. We metrically localize real images with georeferenced rendered images using a dense mutual information technique to allow accurate global pos…

There's No Place Like Home: Visual Teach and Repeat for Emergency Return of Multirotor UAVs During GPS Failure

Michael Warren, Melissa Greeff, Bhavit Patel, Jack Collier, Angela P. Schoellig, Timothy D. Barfoot

RA-L 2019

Redundant navigation systems are critical for safe operation of UAVs in high-risk environments. Since most commercial UAVs almost wholly rely on GPS, jamming, interference, and multi-pathing are real concerns that usually limit their operations to low-risk environments and visual line-of-sight. This
