PROBLEM TO BE SOLVED: To provide a device and method for acquiring a vein pattern, and a vein template, for improving the security of a vein authentication system while reducing a false rejection rate.SOLUTION: The device for acquiring a vein pattern includes: a light source part which emits near-infrared light which is structured (structured near-infrared light) and near-infrared light which is not structured (non-structured near-infrared light) respectively to a part of a living body a light source control part which controls the light source part to switch between the structured near-infrared light and the non-structured near-infrared light an imaging part which images the part of the living body to create imaging data by the structured near-infrared light (structured light imaging data) and imaging data by the non-structured near-infrared light (non-structured light imaging data) an image comparison part which compares the structured light imaging data with the non-structured light imaging data to determine a correspondence of pixels between them and a three-dimensional information calculation part which calculates vein three-dimensional information based on the correspondence of the pixels.COPYRIGHT: (C)2010,JPO&INPIT【課題】本人拒否率を低下させ、静脈認証システムのセキュリティ性を向上させることが可能な静脈パターン取得装置、静脈パターン取得方法および静脈テンプレートを提供する。【解決手段】本発明に係る静脈パターン取得装置は、生体の一部に対して、構造化された近赤外光(構造化近赤外光)および構造化されていない近赤外光(非構造化近赤外光)をそれぞれ照射する光源部と、光源部を制御して、構造化近赤外光と非構造化近赤外光との照射切り替えを行う光源制御部と、生体の一部を撮像し、構造化近赤外光による撮像データ(構造化光撮像データ)と、非構造化近赤外光による撮像データ(非構造化光撮像データ)とをそれぞれ生成する撮像部と、構造化光撮像データと、非構造化光撮像データと、を比較し、これらの間における画素の対応関係を判断する画像比較部と、画素の対応関係に基づいて静脈の三次元情報を算出する三次元情報算出部と、を設けた。【選択図】図5
