Dictionary data registration apparatus and dictionary data registration method
First Claim
1. A dictionary data registration apparatus, comprising:
- a first image input unit that inputs a plurality of images obtained by photographing a face of a registrant in various postures;
a first face detection unit that detects a plurality of face images from the plurality of images inputted by the first image input unit;
a first data collection unit that collects a plurality of face data items based on the plurality of face images detected by the first face detection unit;
a second image input unit that inputs a plurality of images obtained by photographing the face of the registrant while walking;
a second face detection unit that detects a plurality of face images from the plurality of images inputted by the second image input unit;
a second data collection unit that collects a plurality of face data items based on the plurality of face images detected by the second face detection unit;
a synthesizing unit that synthesizes the face data items collected by the first data collection unit and the face data items collected by the second data collection unit; and
a storage unit that stores the synthesized face data items as dictionary data of the registrant.

Abstract
A face data registration apparatus is an apparatus to register dictionary data for walker authentication by use of a face image. The face data registration apparatus causes a posture data collection unit to collect posture variation data from a plurality of face images obtained by photographing a face of a registrant whose posture (face direction) is changed, further causes a walking data collection unit to collect walking data from a face image obtained by photographing a face of the registrant who actually walks along a passage, causes a synthesizing unit to create dictionary data by synthesizing posture variation data and walking data and registers the created dictionary data as dictionary data used to authenticate a person who walks in the passage by face collation into a dictionary data unit.
