[0017] First embodiment

[0018] figure 1 It shows a flow chart of the method for performing identity authentication of a person based on cranial geometric features provided by the first embodiment of the present invention. See figure 1 The first embodiment of the present invention provides a method for the same authentication of a person's identity based on cranial geometric features, which may include:

[0019] Step S11: Recognizing the facial image of the person to be identified to determine a plurality of marking points for marking the cranial features of the person to be identified.

[0020] The facial image is preferably a frontal facial image of a person to be identified, and the person to be identified usually refers to a suspect who is being searched and pursued by a public security agency.

[0021] In a specific embodiment, the left eye, right eye, nose, mouth, cheek, and chin in the facial image of the person to be identified can be automatically identified using, for examp...

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 ...
