Abstract:
A novel scheme for depth extraction is achieved using a multiple
view ring camera system. The ring camera method captures
a series of images of scene from a set of camera locations
arranged in a circular ring. Tracking of scene features
through this sequence realizes circular feature trajectories.
The recovery of depth can be obtained with this method by
determining the diameter of the circular trajectory. Depth
obtained using the ring camera strategy is shown to be more
accurate and more robust than binocular methods. In addition,
associated with this method is a trajectory confidence
measure which provides a good and reliable indication of
depth accuracy.
