Abstract

Abstract Translated from Japanese (57)【要約】 【目的】 左右方向の回転角の生じた顔画像について も、その回転角を補正し、高い精度で個人識別処理を行 なう。 【構成】 識別すべき人物の顔画像を入力する画像入力 部1と、入力された顔画像の特徴点を抽出する特徴点抽 出部2と、顔の3次元構造を記述した基準顔モデル部3 を有し、抽出された特徴点と上記3次元構造を基に顔の 左右方向の回転を補正する補正部4と、個人識別の対象 となる人物の顔画像の特徴点を記録した個人データベー ス部5により、補正された特徴点と個人データベース部 内の特徴点との距離を計算し本人か否かの識別を行なう 判定部6から成る。 (57) [Summary] [Purpose] Even for a facial image with a horizontal rotation angle, the rotation angle is corrected and personal identification processing is performed with high accuracy. [Structure] An image input unit 1 for inputting a face image of a person to be identified, a feature point extraction unit 2 for extracting feature points of the input face image, and a reference face model unit 3 describing a three-dimensional structure of a face. A correction unit 4 that corrects the lateral rotation of the face based on the extracted feature points and the three-dimensional structure, and a personal database unit that records the feature points of the face image of the person to be personally identified. 5, the determination unit 6 calculates the distance between the corrected feature point and the feature point in the personal database unit and identifies whether or not the person is the person.
