Title:
OTHER VIEWPOINT CLOSED SURFACE IMAGE PIXEL VALUE CORRECTION DEVICE, METHOD OF CORRECTING OTHER VIEWPOINT CLOSED SURFACE IMAGE PIXEL VALUE, USER POSITION INFORMATION OUTPUT DEVICE, METHOD OF OUTPUTTING USER POSITION INFORMATION
Document Type and Number:
WIPO Patent Application WO/2012/015059
Kind Code:
A1
Abstract:
A technology for creating an arbitrary viewpoint image with high image quality on the basis of image pixel value information as seen from a single viewpoint, and real spatial positional information has not been known. A hidden point is extracted on the basis of a relative positional relationship between the real spatial positional information for a group of measurement points projectable onto a single viewpoint closed surface, a projection point on the single viewpoint closed surface for an arbitrary measurement point obtained from the image pixel value information for real spatial positional information, and a projection point neighboring the projection point on the single viewpoint closed surface for an arbitrary measurement point obtained from the image pixel value information of the real spatial positional information; a relative positional relationship between a projection point on an other viewpoint closed surface for an arbitrary measurement point, and a projection point neighboring the projection point on the other viewpoint closed surface for the arbitrary measurement point ; the distance from an arbitrary measurement point to another viewpoint position; and the distance from a measurement point projected onto a neighboring projection point on the other viewpoint closed surface to another viewpoint position. Furthermore, the image pixel value of the projection point on the other viewpoint closed surface for the extracted hidden point is corrected using the distance from a measurement point projected onto a neighboring projection point on the other viewpoint closed surface to another viewpoint position, and the image pixel value of the measurement point projected onto a neighboring projection point.
