Face recognition method, system and device and readable storage medium

The invention discloses a face recognition method, a system and a device and a readable storage medium. The face recognition method comprises the following steps: collecting a target face image; performing similarity operation on a plurality of pre-stored first reference images by using the target face image to obtain a first similarity; when the first similarity meets a first preset condition, outputting personnel identity information corresponding to the first reference image, and refreshing a second reference image corresponding to the first reference image; and when the first similarity meets a second preset condition, outputting personnel identity information corresponding to the first reference image. According to the scheme, the accuracy and recall rate of the face recognition system can be effectively improved. 本申请公开了一种人脸识别方法、系统、设备及可读存储介质。该人脸识别方法包括如下步骤：采集目标人脸图像；将目标人脸图像对预存的多个第一参考图像分别做相似度运算，取得第一相似度；当第一相似度满足第一预设条件时，输出所述第一参考图像对应的人员身份信息，刷新所述第一参考图像对应的第二参考图像；当第一相似度满足第二预设条件时，输出所述第一参考图像对应的人员身份信息。本申请的方案能够有效提高人脸
