Lenslet Light Field Panorama Creation: A Sub-Aperture Image Stitching Approach
André Oliveira, Catarina Brites, João Ascenso, Fernando M. B. Pereira · 2018
Typically, a single light field camera only captures a limited portion of the visual scene and the rendered views offer low spatial resolution since the full sensor resolution also needs to capture the light arriving to the sensor from multiple directions. However, many applications require a large field of view and higher spatial resolution, which cannot be offered by a single lenslet light field image. In this paper, a lenslet light field panorama creation solution is proposed based on the stitching of the sub-aperture images associated to several lenslet light fields. The proposed approach consists in capturing multiple light fields with a single lenslet camera, which is rotated to capture different scene angles; corresponding sub-aperture images associated with the multiple light field images are then stitched while avoiding misalignments. The created lenslet light field panorama should preserve the directional light information, thus allowing to change a posteriorithe perspective and the objects in focus on a panorama basis.
