The invention discloses a device and a method for controlling the pose of a television in a multi-vision mode. A lifting motor is installed on a platform and connected with a sliding screw, the sliding screw is sleeved with a sliding block, a rotating motor is installed on the sliding block, and the rotating motor is connected with the back of a television display screen; left and right double-vision cameras are arranged on two sides of the back of the television display screen; the cameras are calibrated to shoot television photos, the horizontal deflecting angle and center coordinates of the television are obtained by pre-processing and edge detection, human pictures are acquired twice by the left and right double-vision cameras at interval, human eye features are extracted for double-view stereo vision construction, the coordinates, horizontal tilting angles and horizontal heights acquired twice are calculated, then the absolute values of two changes are calculated for rotating adjustment and height adjustment, and the deviation absolute values are calculated for compensation. By adopting the device and the method, the pose of the television can be automatically changed according to the pose of the face, so that human eyes do not skew at the television, then fatigue is avoided, and better experience is obtained.
