Method and system for carrying out same identification on personal identity on basis of phrenological geometrical characteristics

Abstract

The present invention discloses a method and a system for carrying out same identification on a personal identity on the basis of phrenological geometrical characteristics. The method comprises: identifying a facial image of a to-be-identified person to determine a plurality of markers used for marking the phrenological geometrical characteristics of the to-be-identified person; generating a plurality of marking lines according to the plurality of markers; and calculating the phrenological geometrical characteristics according to the plurality of markers and the plurality of marking lines, and calculating a first characteristic vector according to the phrenological geometrical characteristics; according to the first characteristic vector and a pre-calculated second characteristic vector, calculating a similarity between the facial image of the to-be-identified person and a docket facial image, which is relevant to a suspected identity of the to-be-identified person, in a public security system, wherein the second characteristic vector is a characteristic vector calculated according to the phrenological geometrical characteristics of the docket facial image; when the similarity is greater than a predetermined threshold, determining that the to-be-identified person is coincided with the suspected identity.

Description

technical field [0001] The present invention relates to the field of technical investigation, in particular to a method and system for identity authentication of personnel based on cranial phase geometric features. Background technique [0002] In the public security business, the identification of the identity of personnel refers to the identity identification of the true identity of suspicious personnel based on the information collected on the spot. In the actual public security case handling process, the same identification of the suspicious person's identity is usually achieved by comparing the facial image of the suspicious person collected on the spot with the recorded facial image in the public security business system related to the suspected identity of the suspicious person. [0003] In terms of the effectiveness of technical investigations, the identification method based on the principle of cranial phase overlap is currently recognized. Lan Yuwen elaborated on ...

AI Technical Summary

Problems solved by technology

However, due to technical limitations, this type of method currently has high requirements for the shooting environment and posture, and is greatly affected by factors such as shooting time intervals and makeup. Therefore, there is a large gap between the reference value of the same identification and the business requirements of the public security department.
