Depth Map
Figure 1: Our axial-cone modeling enables wide-FOV digital refocusing and dense depth estimation using an array of spherical mirrors. We
generate 150
150
FOV refocused images and a dense depth map on a challenging outdoor scene. The estimated depth map is used for
aliasing removal, surface-dependent refocusing, and all-in-focus rendering. The results are depicted using Mercator projection.
Abstract
Catadioptric imaging systems are commonly used for wide-angle
imaging, but lead to multi-perspective images which do not allow
algorithms designed for perspective cameras to be used. Efficient
