More Information
Summary:An object of the present invention relates to personal identification in environments where non-contact is required, and is to realise personal identification with high accuracy even though using a finger vein pattern images unclear and susceptible to positional deviations. There are provided a means for acquiring finger vein patterns without contact, a means for carrying out rotational correction using the outline of a finger as a method of taking out a vein pattern contained in the acquired image, a means for normalising the location of the finger image with reference to the fingertip, a means for acquiring an overall vein pattern statistically by repetitively tracking regions of dark luminance intensities for a desired length from a desired location in the image, a matching means for comparing regions where vein patterns manifest vivid features, and a means for independent matching of subregions and evaluating positional deviations where matching is recognised.
