Abstract: Provided are a method and system for automatically tracking a face position and recognizing a face. In the present invention, after a face image of a user is captured, a capturing unit is moved such that the face image is moved to a face authentication region where optimum face recognition is performed, thereby having a changed capturing direction. This can allow face recognition of the user to be executed without movement of the user. Accordingly, convenience in face recognition can be maximized. Further, a plurality of registered face images are stored with matching frequencies indicating the number of times that the plurality of registered face images have been matched with an authentication image, and the authentication image is firstly compared with registered face images having large matching frequencies. This can enhance a face recognition speed.

Abstract: The present invention relates to a home automation control system and method using face recognition. The present invention includes a face recognition device configured to compare a photographed authentication image of a user's face with a plurality of previously stored face images to perform authentication for user entering a house, a face recognition server configured to receive authenticated user information from the face recognition device and transmit access information for informing whether or not the user enters the house to a user terminal corresponding to the user information, and a home electronic device control unit configured to control the home electronic devices according to preset reservation information from a user when activated by the home automation activation unit, thereby operating the home electronic devices to correspond to the reservation information set by the user according to the user's access.
