step S101, responding to a video call request, and establishing video connection between a first object and a second object, wherein the video call request is a request of the first object to perform video call with the second object initiated by the first device.

In an alternative embodiment, obtaining the target video stream from the video connection includes: according to the video connection, a first image of a first object is acquired, and the first image is displayed to a second object; in the case of abnormal display of the first image, a target video stream is acquired.
Specifically, in the process of acquiring a target video stream according to video connection, first, a first image of a client is acquired according to the video connection, namely, after a video call is connected, a face image (namely, the first image) of the client is automatically acquired by an identity authentication system, and the image is displayed for a video agent customer service through a service interface of a terminal device used by the video agent customer service.
Specifically, if the acquired first image can be normally displayed in the service interface, the video agent customer service clicks the "submit-compare" option, and the identity authentication system adopts a pre-trained face recognition model to perform identity recognition comparison on the first image and the reference image archived by the client, so as to obtain a comparison result; if the acquired first image cannot be normally displayed in the service interface, that is, the first image is abnormally displayed, the identity authentication system acquires the target video stream, for example, acquires the video stream within 1 minute after the video connection is established.

Further, according to the processed image, the face position of the first object can be determined, and the face coordinate information of the first object is generated. Specifically, the face coordinate information is information for representing the position of a face feature point of a client, for example, facial feature position information of a face, a pre-trained face recognition model can calculate gradients of pixels in an image according to the processed image to obtain a gradient histogram, detect the position of the face in the image by using the gradient histogram, cut the face and mark the coordinate position, and generate face coordinate information of the client.
Further, face alignment processing is performed on the processed image according to the face coordinate information, so that an image conforming to a preset shape can be obtained. Specifically, the pre-trained face recognition model can position feature points on a face according to the face coordinate information, and align each feature point to a standard shape through geometric transformation (such as rotation, scaling and the like), namely align the face feature points of a client to a preset standard position (such as a face position of the client in a right posture), so as to obtain an image conforming to the preset shape.
Further, face coding processing is performed on the image conforming to the preset shape, so that a first feature vector of the first object can be obtained. Specifically, the pre-trained face recognition model can re-mark the coordinate positions of the images conforming to the preset shape to obtain face coordinate information, and then the pixel values of the face images are converted into feature vectors through feature extraction processing to obtain first feature vectors of clients.
Further, a reference feature vector of the first object is obtained, and a target image to be authenticated is determined according to the first feature vector and the reference feature vector. Specifically, the reference feature vector is an archived feature vector of the client, that is, a feature vector corresponding to a reference image archived by the client, and the pre-trained face recognition model can determine the target image to be authenticated according to the first feature vector and the reference feature vector.
