Embodiment 1

[0055] Refer to attached figure 1 Shown, the present invention relates to a kind of face recognition method in conjunction with facial vein, and it comprises the following steps:

[0056] 1) Image acquisition and preprocessing: use infrared camera and RGB camera to collect 50 facial vein images and face images of 1000 people respectively, and fuse the facial vein images and face photos, that is, the single-channel facial vein images captured by the infrared camera Image and the three-channel face image captured by the RGB camera are merged to form a new four-dimensional face image, forming a live face image; the collected and preprocessed live face vein image is as follows: figure 2 shown. Then randomly select 500 people from these 1000 people, collect 50 non-living face images and facial vein images from their photos or screens according to the same method, and also perform merging operations to form non-living face images. After collection and preprocessing Non-living fa...

Embodiment 2

[0094] Refer to attached Figure 4 As shown, the present invention also relates to a face recognition device combined with facial veins, which includes:

[0095] 1) The image acquisition and preprocessing module is used for image acquisition and preprocessing, that is, the infrared camera is used to collect facial vein images, the RGB camera is used to collect living face images and non-living face images, and the facial vein images and face photos are processed. Fusion to form preprocessed living face images and non-living face images; the image acquisition and preprocessing module is used to realize the function of step 1) of embodiment 1.

[0096] 2) The network improvement module is used to improve the convolutional neural network, that is, for the convolutional neural network IResNet50, an attention mechanism is added to the channel of each residual block; the network improvement module is used to implement step 2 of Example 1 ) function.

[0097] 3) The training module...

Abstract

The invention belongs to the technical field of biological recognition in the field of information security, and particularly relates to a face recognition method and device based on facial veins. Theface recognition method comprises the following steps: (1) image acquisition and preprocessing; (2) improvement of a convolutional neural network; (3) model training; (4) a registration stage; and (5) a verification stage: judging whether a feature vector corresponds to a certain face or not according to a cosine distance and a cosine similarity threshold. According to the invention, the facial vein features of the human face are fused with the human face, so that the defect that living body detection is difficult in a common RGB image-based human face recognition method is effectively overcome; and moreover, even if the same-egg twins with very similar facial features have great difference in facial vein distribution, the same-egg twins can be effectively distinguished by the method.

Description

technical field [0001] The invention belongs to the technical field of biometric identification in the field of information security, and in particular relates to a face recognition method and device combined with facial veins. Background technique [0002] In recent years, with the development of information technology, face recognition has been widely used in daily life, bringing great convenience to our life. Existing face recognition methods are generally implemented using deep learning-based convolutional neural networks, such as the patent No. CN107247949A disclosed face recognition method, device and electronic equipment based on deep learning, including the construction of convolutional neural networks Model, training model, the trained model will automatically extract the features of the face image and identify its identity. In the existing face recognition methods, the recognition is generally based on the images collected by the RGB camera, but because the face i...
