    摘要: An information processing apparatus obtain a first image in first projection, and a second image in second projection; transforms projection of a first corresponding area of the first image to generate a third image in the second projection; identifies a plurality of feature points in the second image and the third image; determines a second corresponding area in the third image based on the plurality of feature points; corrects the second corresponding area based on a plurality of blocks in the third image, which are determined through matching a plurality of blocks divided from the second image to the third image; transforms projection of a plurality of points in the corrected corresponding area to obtain location information indicating locations of the plurality of points in the first image; and stores the location information in association with the plurality of points in the second image in the second projection.

    摘要: An information processing apparatus calculates a first corresponding area in a first image in first projection, corresponding to a second image in second projection, through first homography transformation; transforms a projection of a peripheral area including the first corresponding area to generate a peripheral area image; calculate a second corresponding area in the peripheral area image through second homography transformation; calculate a third corresponding area in the second image, corresponding to a third image in the second projection, through third homography transformation; reversely transform a projection of the second corresponding area to generate first location information based on a first specific corresponding area in the first image; calculate a fourth corresponding area in the peripheral area image through the second homography transformation; and reversely transform a projection of the fourth corresponding area to generate second location information based on a second specific corresponding area in the first image.

    摘要: An image processing apparatus, an image capturing system, an image processing method, and a recording medium are provided. The image processing apparatus: obtains a first image in a first projection, and a second image in a second projection; transforms projection of at least a part of the first image corresponding to the second image, from the first projection to the second projection, to generate a third image in the second projection; extracts a plurality of feature points, respectively, from the second image and the third image; determines a corresponding area in the third image that corresponds to the second image, based on the plurality of feature points respectively extracted from the second image and the third image; transforms projection of a plurality of points in the corresponding area of the third image, from the second projection to the first projection, to obtain location information indicating locations of the plurality of points in the first projection in the first image; and stores, in a memory, the location information indicating the locations of the plurality of points in the first projection in the first image, in association with the plurality of points in the second projection in the second image.

    摘要: An image processing apparatus obtains a first image in a first projection, and a second image in a second projection; transforms projection of a first corresponding area of the first image to generate a third image in the second projection; identifies a plurality of feature points in the second image and the third image; determines a second corresponding area in the third image, based on the plurality of feature points; generate a reference shape in the second projection, having a relation of projection transformation with the second image; transforms projection of the reference shape to generate a reference shape in the first projection; calculates reference shape conversion data for converting the reference shape to the second corresponding area, using data for transforming projection from the second image to the second corresponding area; and stores the reference shape conversion data in association with reference location data.
