    摘要: A plurality of images (I, J) of an object (M) when viewed from different viewpoints are taken in. One of the images is set as a standard image (I), and the other image is set as a reference image (J). One-dimensional pixel data strings with a predetermined width (W) are cut out from the standard image (I) and the reference image (J) along epipolar lines (EP1, EP2) calculated from a camera parameter (CPR) and the reference point (p). Calculating a phase-only correlation function from the cut one-dimensional pixel data strings will obtain a correlation peak position (Pa1). A positional shift amount (d) from the correlation peak position (Pa1) is obtained. A search is made for a corresponding point (q) corresponding to the reference point (p) based on this position shift amount (d).

    摘要: An iris authentication apparatus includes an iris area extraction unit, registration pattern generating unit, collation pattern generating unit, and collation unit. The iris area extraction unit extracts iris areas from a sensed registration eyeball image and a sensed collation eyeball image. When the iris area extraction unit extracts an iris area from the registration eyeball image, the registration pattern generating unit generates a registration iris pattern image by performing polar coordinate transformation of an image in the extracted iris area. When the iris area extraction unit extracts an iris area from the collation eyeball image, the collation pattern generating unit generates a collation iris pattern image by performing polar coordinate transformation of an image in the extracted iris area. The collation unit collates the registration iris pattern image output from the registration pattern generating unit and the collation iris pattern image output from the collation pattern generating unit on the basis of a correlation therebetween.

    摘要: A personal identification apparatus includes an image sensing device, collation determination circuit, and recognition unit. The image sensing device senses at least part of the face of an identification target. The collation determination circuit collates image pattern information output from the image sensing device with registered pattern information of at least part of the face and outputs an authentication result. The recognition unit causes the identification target to recognize that at least part of the face is located in the focus range of the image sensing device. The recognition unit includes a point source, and a light-shielding member. The light-shielding member is arranged between the point source and the identification target to make the point source invisible or visible from the identification target only when at least part of the face is located in the focus range of the image sensing device and make the point source visible or invisible at another portion.
