Lightweight face recognition method and system suitable for edge device and medium

The invention discloses a lightweight face recognition method and system suitable for edge equipment and a medium. The method comprises the steps of obtaining picture data; constructing a lightweight face recognition network; training the lightweight face recognition network by using the acquired picture data; and loading the trained lightweight face recognition network in edge equipment, and performing face recognition. The invention provides a lightweight face recognition method based on an improved loss function, aiming at solving the problems that a face recognition network is large in parameter quantity and large in computing resource consumption. According to the loss function, an attention mechanism is added on the basis of a center loss function, and then a softmax loss function is fused to jointly supervise training of a recognition network. The improved recognition algorithm reduces the consumption of computing resources, so that the recognition algorithm can be deployed on edge equipment hardware w
