摘要:
A hybrid-resolution panoramic VR generator places High-Resolution (HR) patches from a ring of HR cameras onto a 360-degree Low-Resolution (LR) image from a LR camera pointing upward from the ring into a panoramic mirror that captures the combined field of view of all the multiple HR cameras, but at a lower resolution. Ghosting artifacts caused by parallax errors between adjacent HR cameras are eliminated because object placement is determined by the 360-degree LR image. Each HR image is homographicly projected into 3 projections by grouping objects of different depths to obtain homographic matrixes. The 360-degree LR image is upscaled to HR and a query patch is searched in search windows in the three projections for up to two adjacent HR images. Best-matching patches are weighted by similarity with the query patch and blended to generate a reconstructed patch placed at the query patch location in a reconstructed HR panorama image.
