HIGH RESOLUTION (HR) PANORAMA GENERATION WITHOUT GHOSTING ARTIFACTS USING MULTIPLE HR IMAGES MAPPED TO A LOW-RESOLUTION 360-DEGREE IMAGE

摘要

A hybrid-resolution panoramic VR generator places High-Resolution (HR) patches from a ring of HR cameras (22) onto a 360-degree Low-Resolution (LR) image (30) from a LR camera (24) pointing upward from the ring into a panoramic mirror (26) that captures the combined field of view of all the multiple HR cameras (22), but at a lower resolution. Ghosting artifacts caused by parallax errors between adjacent HR cameras (22) are eliminated because object placement is determined by the 360-degree LR image (30). Each HR image (34) is homographicly projected into 3 projections by grouping objects of different depths to obtain homographic matrixes. The 360-degree LR image (30) is upscaled to HR and a query patch is searched in search windows in the three projections for up to two adjacent HR images (34). Best-matching patches are weighted by similarity with the query patch (72) and blended to generate a reconstructed patch (78) placed at the query patch location in a reconstructed HR panorama image (68).
