Matching Spherical Panoramas and Planar Photographs By Gail Carmichael Fall 2009 A thesis submitted to the Faculty of Graduate Studies and Research in partial fulfillment of the requirements for the degree of Master of Computer Science
Ottawa-Carleton Institute for Computer Science School of Computer Science Carleton University Supervisor: Prosenjit Bose Co-Supervisor: Robert Laganiere ABSTRACT Image matching and the epipolar geometry for a stereo pair has been a well-studied topic in the field
of computer vision. There is a strong foundation for matching techniques between two planar images,
and the case of two spherical panoramas has been more recently explored. This work establishes
the geometry for a pair consisting of one planar image and one spherical panorama, while exploring
matching techniques that will perform well for scenes with repetitive features. A pseudo-fundamental
matrix is defined for use with one calibrated image and one uncalibrated. This allows a photograph
to be used without calibration while a panorama can be more easily considered as a whole. A
global context descriptor for Speeded Up Robust Features and Maximally Stable Extremal Regions
improves matching results and automatically computed epipolar geometry for scenes with buildings
having repetitive features.
