Information processing apparatus and method

摘要

An apparatus includes a setting unit for setting a virtual viewpoint; a determining unit for determining an undefined area in which an object distance cannot be defined in a virtual image of the virtual viewpoint, from image data of a plurality of images photographed by a plurality of photographing units placed at different positions; a correction setting unit for setting an amount of correction of a position of at least one of the photographing units from the undefined area; and a generating unit for generating the image of the virtual viewpoint from image data of a plurality of images photographed by the plurality of photographing units placed at positions that are corrected in accordance with the amount of correction.

1. An apparatus that generates a distance map corresponding to a virtual viewpoint using images captured by a plurality of capture units placed at different positions, the virtual viewpoint being different from positions at which the capture units are placed, the apparatus comprising:
a viewpoint setting unit to set a virtual viewpoint; a determining unit to determine an undefined area in which an object distance cannot be defined in an image corresponding to the virtual viewpoint, using image data of a plurality of images captured by a plurality of capture units placed at different positions; a correction setting unit to set an amount of correction of a position of at least one of the capture units according to a shape of the undefined area; and a generating unit to generate a distance map corresponding to the virtual viewpoint using image data of a plurality of images captured by the plurality of capture units, wherein at least one of the plurality of capture units is placed in a position corrected in accordance with the set amount of correction,wherein the determining unit sets a plurality of distance candidates for each pixel in the image corresponding to the virtual viewpoint, and determines, as a pixel that composes the undefined area, a pixel, whose number of distance candidates with a high reliability level is larger than a predetermined number, in the image corresponding to the virtual viewpoint,wherein the determining unit determines a distance candidate as a distance candidate with the high reliability level among the plurality of distance candidates in a case where a variance of feature values of pixels in the plurality of images corresponding to the pixel in the image corresponding to the virtual viewpoint obtained from the distance candidate is less than a predetermined threshold.
