Abstract
A user recognition and confirmation device includes an image sensing unit, a face recognition unit, a display unit and an expression recognition unit. The image sensing unit captures a first image frame and a second image frame. The face recognition unit is configured to recognize a user ID according to the first image frame. The display unit is configured to show ID information of the user ID. The expression recognition unit is configured to confirm a user expression according to the second image frame and output a confirm signal. There is further provided a user recognition and confirmation method and a central control system for vehicles.
Claims13
A user recognition and confirmation method, comprising:
- capturing, by an image sensing unit, a first image frame;
- recognizing a user ID according to the first image frame;
- showing ID information, which is previously stored in a storage unit, of the recognized user ID on a screen of a display unit;
- capturing, by the image sensing unit, a second image frame;
- generating a confirm signal when a happiness expression is recognized by calculating an expression feature in the second image frame and comparing the recognized expression feature with stored expression data associated with a predetermined happiness expression to confirm whether the recognized user ID is correct or not according to the second image frame captured after the ID information is shown by the display unit;
- and
- controlling a steering wheel height according to the confirm signal.
