摘要

Facial image - detection method, which is a robot (2) with a camera (21a) and an arm (27) is used, wherein said method comprises the steps of:a) detecting a target person, the facial image from a by means of the camera (21a) resulting image is to be detected, and the approach of the robot (2) to the target person;b) moving the arm (27) on the target person to; andc) performing a recorded image of the face image of the target person within a predetermined time period;characterized by the,that prior to step a) the target person with a stationary monitoring camera (4) is detected and from this location information of the target person within a formulation is obtained in the position region,that in step b) based on the by means of the stationary monitoring camera (4) of the position information obtained of the arm (27) is moved to the target person, in order to offer the target person a handshakes, when the approach of the robot (2) to the target person is completed;that in step c) by means of the camera (21a) of the robot (2) the facial image of the target person triggered by actuation of a hands vibrating - sensor during the hands shaking with the target person is recorded;that step c) comprises the steps of:Detecting a predetermined number of face images of the target person when the recorded image of the face image of the target person is carried out;Calculating the similarity of the last face image to a classes image, which is made of all face images is generated in addition to the last face image;Repeating the recorded image of the face image, to the calculated similarity exceeds a threshold value; andThe termination of the recorded image of the face image prior to a predetermined period of time has elapsed, andthat in a step d) the face image obtained in step c) in a database for user information (34b) is stored.
