example 1
[0138] Obtain the target calculation result according to the preset formula Z1 / Z2 and L1, R1, L2, R2, wherein, Z1=L1 / R1, Z2=L2 / R2;
[0139] Then, judging whether the target calculation result is the first preset threshold;
[0140] If the target calculation result is the first preset threshold, whether the first face image and the second face image are obtained by ingesting the face of a living body, otherwise the first face image and the second face image are not obtained by ingesting a living body obtained from a human face.
example 2
[0142] Obtain the target calculation result according to the preset formula (Z1-Z2) / (Z1+Z2) and L1, R1, L2, R2, Z1=L1 / R1, Z2=L2 / R2;
[0143] Then, judging whether the target calculation result is less than a second preset threshold;
[0144] If the target calculation result is less than the second preset threshold, whether the first face image and the second face image are obtained by ingesting a live face, or whether the first face image and the second face image are obtained by ingesting obtained from living human faces.
[0145] Wherein, the setting of the preset threshold may be set by user input, or may be obtained through training of the device. In the way of obtaining the preset threshold through the training of the device, the face anti-counterfeiting method of the embodiment of the present invention also includes:
[0146] C1: Obtain a flat face image and an image of a live face;
[0147] C2: Use the distance calculation rules to train the plane face image and the ...
