java 实现人脸识别登录百度云ai 是免费的么

百度云人脸识别属于免费的个人认证一秒内QPS别超过两次，企业认证后一秒别超过十次是不收费的

1、首先，开通一个百度云账号

在产品服务里面找到人脸识别这个产品

2、点开之后选择创建应用

3、创建一个应用、起一个名称点击创建即可

4、打开创建好的应用列表，注意一会就是用的这里的APPID 还有A、K

开始上代码，先说场景，这里的需求是显示类似于支付宝刷脸登陆的那种，作为后台来说，只能是前台把照片传给我们，我们再去对比，一开始那种眨眨眼、摇摇头等，那是前端要做的活，只是检测是否为活体，防止用户手动拍着一张静态照片通过，在进行活体检测的时候，百度会给APP端或者前端多张图片，比如说主图、点头的图、摇头图等，我们拿到这些图后，一般拿主图去对比，毕竟可能是唯一的一张正脸照，取出之前存的本人照片，两张都要转成base64去对比
