The utility model adopts image processor to judge and watches personnel positions and sound state, the employing image content calculates and playing device carries out 2D and stereoscopic picture plane switches; Thereby be applicable on the bore hole screen of all gratings or lens material, can present the tracking effect at the solid screen of any visual angle number.
Description of drawings
Below in conjunction with accompanying drawing, the embodiment of the utility model is elaborated:
Fig. 1: detection type two dimension and stereoscopic picture plane switching device block diagram that the utility model proposes.
Embodiment
As shown in Figure 1, the utility model comprises:
Image display device 1: grasp image immediately;
Image processor 2: comprise position of human eye detection architecture 21 and personnel movement decision structure 22; Be used to handle the image that the image display device is provided, and, find out people's face position, judge personnel's sound state according to face characteristic;
Image content calculates and playing device 3: comprise that image content computation structure 31,2D and stereoscopic picture plane switch play structure 32; According to position of human eye angle parameter, personnel's sound state parameter and three-dimensional display calculation of parameter go out to present to beholder's picture data, give three-dimensional display;
Three-dimensional display 4: the equipment that is used to show stereopsis;
Position of human eye detection module in the image processor: be the basis with the adaboost algorithm; The image data that is provided with the image display device; Find out position of human eye, according to the position of position of human eye and 3 d display device central point, calculate the angle theta 1 of two positions again.
Personnel movement determination module in the image processor: a spatial dimension α and a time length β are set; If β in the time from the figure of image processor that video camera is sent to people's face moving range that finds exceed α; Judge that then this person moves, otherwise judge that then this person is in the fixed position.
Image content calculates with playing device need be provided with the three-dimensional display parameter; This parameter need comprise the basic document of three-dimensional display; Comprise the visual angle and count P1, with Pixel Mapping data P2 (Pixel Mapping data need comprise the data of position, the corresponding visual angle of Pixel)
Image content calculates with playing device and needs to make down column count according to three-dimensional display parameter and people's state:
1, P1=2, the people is in the fixed position
P1=2 represent that the three-dimensional screen of this one side for 2-View, has only two visual angles, are respectively LOOK LEFT and LOOK RIGHT; The people indicates to appear stereoscopic picture plane and gives the beholder in the fixed position, image content calculates with playing device needs elder generation according to θ 1 value that image processor provided, and multiply by a weighted value again and obtains its A1 as a result.If A1 is an even number; The LOOK LEFT image of two visual angle stereopsis will be followed according to the Pixel Mapping data of P2 and passed to the LOOK LEFT picture position, and the LOOK RIGHT image will be passed to the LOOK RIGHT picture position with the Pixel Mapping data according to
; If A1 is an odd number; The LOOK LEFT image of two visual angle stereopsis will be passed to the LOOK RIGHT picture position with the Pixel Mapping data according to
, and the LOOK RIGHT image will be passed to the LOOK LEFT picture position with the Pixel Mapping data according to
2, P1=2, the people is moving
P1=2 represent that the three-dimensional screen of this one side for 2-View, has only two visual angles, are respectively LOOK LEFT and LOOK RIGHT; The people indicates to appear the bidimensional picture and gives the beholder moving, and image content calculates and can then go out arbitrary visual angle image (LOOK LEFT image or LOOK RIGHT image all can) from two visual angle stereopsis choosings with playing device and play LOOK LEFT picture position and the LOOK RIGHT picture position of inserting three-dimensional screen with the Pixel Mapping data according to
