Dual-fisheye lens stitching for 360-degree imaging
This addresses the issue of poor stitching quality in 360-degree imaging for users of dual-fisheye cameras, but appears incremental as it focuses on a specific camera model and hard-to-stitch objects.
The paper tackled the problem of visible discontinuities in stitching boundaries for dual-fisheye lens cameras used in 360-degree imaging, introducing a novel method that adaptively minimizes these discontinuities to generate full spherical images, with results showing good quality stitched images for the Samsung Gear 360 camera.
Dual-fisheye lens cameras have been increasingly used for 360-degree immersive imaging. However, the limited overlapping field of views and misalignment between the two lenses give rise to visible discontinuities in the stitching boundaries. This paper introduces a novel method for dual-fisheye camera stitching that adaptively minimizes the discontinuities in the overlapping regions to generate full spherical 360-degree images. Results show that this approach can produce good quality stitched images for Samsung Gear 360 -- a dual-fisheye camera, even with hard-to-stitch objects in the stitching borders.
