The invention discloses a user authentication method and a device for an unmanned aerial vehicle charging cabinet and the charging cabinet. The method comprises the following steps: receiving acquired registered user electronic tag information and a registered user face image; establishing a hidden Markov model, and training the hidden Markov model according to the registered user face image to obtain a registered user face model; storing the plurality of registered user face models to form a registered user face model library; associating the electronic tag information of the registered user with the face model of the registered user; receiving the collected face image of the user to be authenticated and the electronic tag information of the user to be authenticated; calculating a likelihood value according to the to-be-authenticated user face image and each registered user face model in a registered user face model library, and obtaining a face recognition result based on the maximum likelihood value; confirming the identity of the user according to a face recognition result and the electronic tag information of the user to be authenticated; the method has high recognition rate and robustness.
本发明公开了一种用于无人机充电柜的用户认证方法、装置及充电柜,其中方法包括:接收采集的注册用户电子标签信息和注册用户人脸图像;建立隐马尔科夫模型,根据所述注册用户人脸图像对隐马尔科夫模型进行训练,获得注册用户人脸模型;将多个注册用户人脸模型进行存储,形成注册用户人脸模型库;将注册用户电子标签信息与注册用户人脸模型进行关联;接收采集的待认证用户人脸图像和待认证用户电子标签信息;根据待认证用户人脸图像和注册用户人脸模型库中的各个注册用户人脸模型计算似然值,基于最大似然值获得人脸识别结果;根据人脸识别结果和所述待认证用户电子标签信息,确认用户身份;该方法具有较高的识别率和鲁棒性。
