Wide-FOV Monocentric LF Camera

This work presents the first single-lens wide-field-of-view (FOV) light field (LF) camera. Shown above are two 138° LF panoramas and a depth estimate. These are 2D slices of larger 72 MPix (15 × 15 × 1600 × 200) 4D LFs. The depth estimate is based on a standard local 4D gradient method. The superresolution, parallax pan, and refocus examples below demonstrate more of the 4D structure of these panoramas. Click here for individual Panoramas.

Both wide-FOV and LF capture have been shown to simplify and enhance a range of tasks in computer vision, and we expect their combination to find application spanning autonomous vehicles, virtual and augmented reality capture, and robotics in general.
