RAPID 3D SCENE RECONSTRUCTION FROM KITE-BASED AERIAL IMAGERY USING OPEN SOURCE STRUCTURE FROM MOTION A Thesis Project submitted in partial fulfillment of the requirements for the degree of Masters of Science at George Mason University by Michael Roy Resig Bachelor of Arts Wheaton College, IL 2009 Director: Arie Croitoru, Professor Department of Geoinformatics and Geospatial Intelligence Fall Semester 2014 George Mason University Fairfax, VA THIS WORK IS LICENSED UNDER A CREATIVE COMMONS ATTRIBUTION-NODERIVS 3.0 UNPORTED LICENSE. ii DEDICATION This is dedicated to my loving and wonderful wife Hannah. Your continual support has motivated me throughout the years to keep chasing my passions and enjoy life. Also to my family, who always taught me to pursue my interests with vigor and integrity and supported me every step of the journey. iii ACKNOWLEDGEMENTS I would like to thank the many friends, coworkers, and supporters who have helped make my degree and thesis possible. Without them, I would not have had the opportunity to pursue this degree. Dr. Matt Rice, Dr. Arie Croitoru, and Dr. Anthony Stefanidis were pivotal in guiding and educating me during my Master program. Finally, I would like to thank my past professors and mentors for guiding me to where I am today. Their dedication to education and excellence gave me the tools to excel at life and learning. iv TABLE OF CONTENTS Page List of Tables
