Steve Maybank received the BA degree in mathematics from King's College Cambridge in 1976 and the PhD degree in computer science from Birkbeck College, University of London in 1988. He was a research scientist at GEC from 1980 to 1995, first at MCCS, Frimley, and then, from 1989, at the GEC Marconi Hirst Research Centre in London. In 1995, he became a lecturer in the Department of Computer Science at the University of Reading and in 2004, he became a professor in the Department of Computer Science and Information Systems at Birkbeck College, University of London. Steve's research interests include camera calibration, visual surveillance, tracking, filtering, applications of projective geometry to computer vision and applications of probability, statistics and information theory to computer vision. He is the author or co-author of more than 160 scientific publications and one book. He is a Fellow of the IEEE and a Fellow of the Royal Statistical Society. He received the Koenderink Prize in 2008.
Abstract: Structure from Motion (SFM) refers to the task of inferring camera positions and the 3D shape of a scene from a sequence of images. In this tutorial I describe the equations on which SFM is based. The algorithms for inferring SFM from these equations are not described. The topics covered include projection to an image plane, coordinate frames, transformation of coordinates from one frame to another, vector products, the projective plane, the fundamental matrix, the essential matrix and homographies of the plane.
