FACE VERIFICATION METHOD AND APPARATUS BASED ON TRIPLET LOSS, AND COMPUTER DEVICE AND STORAGE MEDIUM

The present invention relates to a face verification method and apparatus based on Triplet Loss, and a computer device and a storage medium. The method comprises: based on a face verification request, acquiring a certificate photograph and a scenario photograph of a person; respectively performing face detection, key point positioning and image pre-processing on the scenario photograph and the certificate photograph, so as to obtain a scenario face image corresponding to the scenario photograph and a certificate face image corresponding to the certificate photograph; inputting the scenario face image and the certificate face image into a pre-trained convolutional neural network model used for face verification, and acquiring a first feature vector corresponding to the scenario face image and a second feature vector corresponding to the certificate face image, which feature vectors are output by the convolutional neural network model; calculating a cosine distance between the first feature vector and the secon
