Baidu face recognition （ This is used v3 edition ）
Business needs ： Create a theme , There are multiple activities under a theme , As long as users sign up on the theme, they can sign in under multiple activities , Face check-in is used here （ Users can sign in with their own faces , Staff can also help shoot and sign in ）, Users who sign up will enter face information into Baidu cloud face database , When checking in, go to Baidu cloud face database to find , If you find it, you can sign in , If you don't find it, you can't sign in .
