Abstract

PURPOSE:To attain the quick personal identification by obtaining a distance showing the difference between the unknown face data produced when a certain person enters and leaves out of a specific place and the registered face data on a person who is already registered in a decision processor and is permitted to enter and leave out said place and rejecting the entering and leaving-out of a person if said distance is out of the set allowable value. CONSTITUTION:A decision processor 4 stores previously the identification data (face data) on the profile lines of all persons who are permitted to enter and leave out a specific place in the memories like a ROM, RAM, etc. A video input device 2 photographs the profiles of persons to be checked at the time of their entering and leaving-out and calculates the difference from the unknown face data obtained by a contour signal processor 3. When this difference value is within the allowable distance value, the relevant person is permitted to enter and leave out said place. In such a way, a non-contact personal identification system is obtained with no special input operation required for a person to be checked.

By the way, personal identification devices that utilize body characteristics such as handprints, retinas, and fingerprints have existed for some time, but these devices require that a part of the body be fixed to a data input device to capture data regarding body characteristics. It is a contact type device that can be placed on or placed on the data input device, and therefore, when the person being measured inputs physical characteristics, special input operations such as fixing a part of the body to the data input device are required. And it's very annoying.

In order to achieve the above object, the present invention extracts the outline of a profile by using time-divided scanning lines and the number of scanning lines of a video signal of a profile, which is a shape feature of a person, obtained by photographing with a television camera. Differences between unknown face data created when a certain person enters and exits a specific place, and registrant face data of a person who has been registered in the determination processing device and is permitted to enter and exit. The gist of the non-contact personal identification method is to calculate the distance representing the distance, and if the distance is within a set tolerance, entry is permitted, and if it is outside the tolerance, entry is denied.
