  • Publication number: 20230351611
    Abstract: A method for tracking a moving human target and a device, the target tracking device comprises radar unit and camera unit. The method first obtains first positional information of a target through the radar unit, then obtains a display area image comprising the target through the camera unit based on the first positional information. Upon determining the target as human, the method determines whether an initial position of face of the target is centered within the display area image. If not centered, compensation is continuously applied to the radar unit from calculations on information as to orientations and distances from the radar unit and the camera unit, the radar unit and the camera unit being controlled to conduct face tracking of the moving target.
