Stereoscopic image processing device, method, recording medium and stereoscopic imaging apparatus

A stereoscopic image processing method, comprising:

• an image acquisition step of acquiring a plurality of images of an identical subject taken from a plurality of viewpoints;
• a corresponding point detection step of selecting a prescribed image as a reference image from among the acquired plurality of images, selecting an image other than the reference image as a target image from among the acquired plurality of images, and detecting a plurality of feature points from the reference image and a plurality of corresponding points from the target image to generate a plurality of pairs of the feature point and corresponding point, wherein feature of the feature point and the corresponding point included in the same pair are substantially identical to each other;
• a parameter estimation step of estimating geometrical transformation parameters for geometrically transforming the target image such that y coordinate values of the feature points and the corresponding points included in the same pair are substantially identical to each other, wherein y direction is orthogonal to a parallax direction of the plurality of viewpoints;
• and
• an image transformation step of geometrically transforming the target image on the basis of the estimated geometrical transformation parameters.

A computer-readable medium comprising a computer program causing a computer to execute a process for a stereoscopic image processing, the process comprising:

• acquiring a plurality of images of an identical subject taken from a plurality of viewpoints;
• selecting a prescribed image as a reference image from among the acquired plurality of images, selecting an image other than the reference image as a target image from among the acquired plurality of images, and detecting a plurality of feature points from the reference image and a plurality of corresponding points from the target image to generate a plurality of pairs of the feature points and corresponding points, wherein features of the feature points and the corresponding points included in the same pair are substantially identical to the feature points respectively;
• estimating geometrical transformation parameters for geometrically transforming the target image such that y coordinate values of the feature points and the corresponding points included in the same pair are substantially identical to each other, wherein y direction is orthogonal to a parallax direction of the plurality of viewpoints;
• and
• geometrically transforming the target image on the basis of the estimated geometrical transformation parameters.
