Paper Abstract

This paper deals with quantitative aspects of camera fixation for reconstruction of a static scene. In general when the camera undergoes translation and rotation there is an infinite number of points that produce equal optical flow for any instantaneous point in time. For the case where the rotation axis of the camera is perpendicular to the instantaneous translation vector these points form a circle (called the Equal Flow Circle or simply EFC) and a line. A special case of the EFCs is the Zero Flow Circle (ZFC) where both components of the optical flow are equal to zero. A fixation point is the intersection of all the ZFCs. Points inside and outside the ZFC are quantitatively mapped using the EFCs. We show how to find the exact location of points in space during fixation. 1.
