Face recognition method and device, server and storage medium

The invention provides a face recognition method and device, a server and a storage medium, and relates to the field of artificial intelligence. The method comprises the following steps: receiving a to-be-recognized image of a target customer sent by image acquisition equipment; wherein the to-be-recognized image is obtained by acquiring face information of a target customer by an image acquisition device; cutting a face region of the to-be-recognized image to obtain a to-be-recognized face image; compressing the number of channels of the to-be-recognized face image to obtain a first feature map; processing the first feature map through depth separable convolution to obtain a second feature map; splicing the first feature map and the second feature map to obtain a third feature map; and inputting the third feature map into the optimized face recognition model to output a recognition result of the target customer. According to the method provided by the invention, the face recognition efficiency and accuracy a
