This paper addresses the problem of recovering the generating curve of
a surface of revolution from a single uncalibrated perspective view,
based solely on the object's outline and two (partly) visible
cross-sections. Without calibration of the camera's internal
parameters such recovery is only possible up to a particular
transformation of the true shape. This is however sufficient for 3D
reconstruction up to a 2\,DOF transformation, for recognition of
objects, and for transfer between views. We will describe the basic
algorithm and show some examples.
