Abstract: Embodiments of this application relate to a method and an apparatus for detecting a status of a driver. The method includes: obtaining a first image frame and a second image frame, where both the first image frame and the second image frame are image frames including the face of a driver, and the first image frame is an image frame captured before the second image frame; obtaining first detection information of the first image frame and second detection information of the second image frame, where both the first detection information and the second detection information indicate an eye status and a head pose of the driver; and when the second detection information indicates that a first eye status corresponding to the second image frame is an eye-closed state, determining, based on the first detection information and the second detection information, a second eye status corresponding to the second image frame.

Abstract: The present disclosure relates to methods and apparatuses for identifying an object of interest of a user. One example method includes obtaining information about a line-of-sight-gazed region of the user and an environment image corresponding to the user, obtaining information about a first gaze region of the user in the environment image based on the environment image, where the first gaze region is used to indicate a sensitive region determined by using a physical feature of a human body, and obtaining a target gaze region of the user based on the information about the line-of-sight-gazed region and the information about the first gaze region. The gaze region is used to indicate a region in which a target object gazed by the user in the environment image is located.
