Problems solved by technology

However, this feature has not been utilized in the current research on human ear recognition methods.
[0011] (2) In the measurement of auricle shape and structure, the determination of reference coordinates is very important. The current method of determining reference coordinates is not accurate and stable enough, which directly affects the measurement results of auricle shape and structure, resulting in a low ear recognition rate
However, data retrieval shows that there is no research report in this area

Embodiment Construction

[0039] The human ear recognition flow process that the inventive method proposes is as shown in Figure 1, and concrete implementation steps are as follows:

[0040] Step 1: Get the front and side images of the face

[0041] The specific operation is to first set up the camera

[0042] The positional relationship between the two cameras and people is shown in Figure 2. Camera 1 takes a frontal image of a human face, and camera 2 takes a profile image of a human face. The spatial positional relationship between the two cameras and the person can be realized in a fixed manner or in a variable manner. In order to facilitate image processing, the shooting distance between the camera and the person should be kept constant, so that the size of the head remains relatively unchanged in each captured image.

[0043] For the fixing method, the camera 1 is perpendicular to the front of the face, and the camera 2 forms a certain angle with the face, preferably 45°, because the angle betwe...

Abstract

The invention is the recognition method for the character of man's face and ears, including the technique processes: get the images of the front and the side face, pick up the parameters of face structure character and the auricle size character through the front face image, and the parameters of the auricle shape and structure characters through the side face image, and combine the character attestation. This invention has the strong points of convenient method of getting image, the low cost of equipment, the stable character and the accurate attestation.

Description

technical field [0001] The invention belongs to the personal identity identification technology based on human biological feature identification, in particular to the measurement and combined identification of ear features and face features. Background technique [0002] Identity verification is a basic problem that everyone encounters on a regular basis. Identity verification is mainly used in banking, customs, public security, e-commerce, e-government, network security and other occasions that need to verify personal identity. [0003] Traditional identity verification mainly has the following two methods: (1) through various certificates, such as ID cards, work permits, credit cards, savings cards, phone cards, etc.; (2) through personal identification numbers and passwords. Its main disadvantage is that it is easy to be stolen, and the former is easy to lose, and the latter is easy to forget, which are not safe enough. [0004] Identity confirmation based on human biom...
