Embodiment 1

[0026] An identity authentication method for palmprint and face fusion recognition provided by the present invention, such as figure 2 shown, including:

[0027] Step 201, obtaining a face image;

[0028] Step 202, obtaining the palmprint image;

[0029] Step 203, call the face recognition command to recognize the acquired face image, and obtain the face recognition result;

[0030] Step 204, calling the palmprint recognition command to recognize the acquired palmprint image, and obtain the palmprint recognition result;

[0031] Step 205, judging whether the identity authentication is passed according to the obtained face recognition result and palmprint recognition result.

[0032] In the above step 201 and step 202, the face image and the palmprint image are acquired respectively by using an image acquisition device. In order to use the same image acquisition device to obtain the palmprint image and the face image, the present invention uses a non-contact image acquisit...

Embodiment 2

[0042] In order to improve the efficiency of identity authentication, another embodiment of the present invention provides an identity authentication method of palmprint and face fusion recognition, such as image 3 shown, including the following steps.

[0043] Step 301, acquiring a face image. This step is the same as the method and working process adopted in step 201 of Embodiment 1.

[0044] Step 302, call the face recognition instruction to recognize the acquired face image, and obtain the first similarity score and the first identity. This step is implemented in the same manner as step 203 in Embodiment 1. For specific implementation, refer to step 203 in Embodiment 1. Through this step, the recognition result of the face image can be obtained, including: obtaining the first similarity score and the first identification.

[0045] Step 303, judging whether the first similarity score is greater than a preset first threshold.

[0046] When the first similarity score is ...

Embodiment 3

[0055] In the case that the efficiency of identity authentication is required to be higher, when the obtained palmprint image is identified in step 305 of the above-mentioned embodiment 2, it is not necessary to combine the obtained palmprint texture features with the prestored user identity information database. All palmprint features are compared and identified. Instead, according to the first identity obtained in step 302, extract all palmprint feature templates corresponding to the first identity from the preset identity information database; then, combine the obtained palmprint texture features with the extracted first identity All palmprint feature templates corresponding to the identification are compared and identified, and the highest similarity score is obtained as the second similarity score. In the above step 306, it is judged whether the second similarity score is greater than the preset second threshold, and when the second similarity score is greater than the pr...

Abstract

The invention relates to an identity authentication device adopting palmprint and human face fusion recognition, which comprises an image acquisition module, a main processing module and a memory module, wherein the main processing module further comprises a control unit which is electrically connected with the image acquisition module, a human face recognition unit and a palmprint recognition unit which are respectively connected with the control unit, and the memory module which is respectively connected with the human face recognition unit and the palmprint recognition unit. The image acquisition module is used for time-division shooting of biological characteristic images according to a command of the control unit and sending the shot biological characteristic images to the control unit, and the biological characteristic images comprise a human face image and a palmprint image. The control unit is used for sending the shot images to the corresponding human face recognition unit or the palmprint recognition unit for recognition and judging whether identity authentication passes or not according to the human face recognition result and the palmprint recognition result. The problem of needing two acquisition devices for performing double biological characteristic identity authentication is solved, the safety is high and the cost is low.

Description

technical field [0001] The invention relates to the field of biological feature recognition, in particular to a method and device for fusion recognition of palmprint and human face. Background technique [0002] Biometric identification technology is listed as one of the top ten technologies that have had a revolutionary impact on human society in the 21st century. Biometric identification technology is currently the most convenient and safe identification technology, which identifies the person himself and does not require external markers. Biometric recognition technology utilizes human physiological and behavioral characteristics for identification, mainly including fingerprint recognition, face recognition, iris recognition, gait recognition, vein recognition, and palmprint recognition. [0003] Among the numerous biometric identification technologies, fingerprint identification and face recognition technologies are the most mature and widely used. Compared with finger...
