Abstract
The invention relates to the technical field of three-dimensional displaying, in particular to a three-dimensional automatic signal identifying method which is characterized by comprising the following steps: selecting three-dimensional videos adopting a side by side format, respectively extracting outline information of left eye images and right line images of each frame in the video, calculating similarity of left eye image outline information and right eye image outline information, and judging whether input signals are two-dimensional or three-dimensional signals according to the similarity. Due to the fact that no displaying devices with a three-dimensional automatic identifying function are provided at present, existing three-dimensional displaying is mainly completed through manual switching. The three-dimensional signal automatic identifying method provides a three-dimensional automatic identifying method, and by means of the method, three-dimensional signals can be automatically identified and further a displaying method can be switched or corresponding prompts can be given according to identified results.
Description
Technical field
The present invention relates to the dimension display technologies field, especially a kind of 3D signal automatic-identifying method.
Background technology
D is the abbreviation of English Dimension (dimension, dimension), and 3D is exactly the three-dimensional meaning.Compare common 2D picture, 3D is three-dimensional more true to nature, lets spectators that sensation on the spot in person is arranged.Present 3D technology can be divided into two kinds of bore hole formula and spectacles, and bore hole formula 3D technology is mainly used in industrial commercial demonstration aspect at present, and in the display device such as mobile phone; Spectacle 3D technology then is mainly used in consumer level market.Spectacle 3D technology can be divided into three kinds of aberration formula, fast gate-type and polarization types (also being look point-score, time-sharing procedure, light point-score); And bore hole formula 3D technology can be divided into lens arra, barrier fence and point to three kinds of light sources, and the principle of every kind of technology and imaging effect all have certain difference.
Summary of the invention
The purpose of this invention is to provide a kind of 3D signal automatic-identifying method, can discern the 3D signal automatically.
A kind of 3D signal automatic-identifying method; Its special feature is; Comprise the steps: to select to adopt the 3D video of left and right sides form; Extract the profile information of each frame left-and right-eye images of video respectively, calculate the similitude of right and left eyes image outline information, judge that according to similitude input signal still is the 3D signal for the 2D signal.
If to judge input signal be the 3D signal then point out the viewers wear glasses to watch, and confirm to carry out 3D and show.
A kind of 3D signal automatic-identifying method; Its special feature is; Comprise the steps: that the signal that one or one field of reservation identifies input in original video lead frame form is 2D signal or 3D signal, when decoding, judge that through position or the field of discerning this special use input signal is 2D signal or 3D signal then.
Because the present display unit that does not also possess the automatic recognition function of 3D, therefore existing 3D demonstration is main still switches completion through the people by hand.The inventive method provides a kind of 3D automatic identifying method, adopts this method just can realize the automatic identification of 3D signal, thereby can or provide corresponding prompting according to recognition result switching displayed mode.

Fig. 1 is the 3D signal recognition method flow chart of embodiment 1 among the present invention.
Fig. 2 is the video lead frame form among the embodiment 2 among the present invention.
Embodiment
Embodiment 1:
As shown in Figure 1; (left side one side of something is a left-eye image to select to adopt left and right sides form; Right one side of something is eye image) the video of 3D film source, extract the profile information of each frame left-and right-eye images of video respectively, specifically adopt the profile information of edge detection algorithm acquisition right and left eyes image; Calculating the similitude of right and left eyes image outline information, specifically is that the right and left eyes profile carries out the difference computing.Judge that according to similitude input signal for the 2D signal still is the 3D signal, specifically is to judge similitude according to the difference operation result again, for example the difference operation result is less than 15 but be not 0 entirely and think 3D rendering input, otherwise then is the 2D signal.
If to judge input signal be the 3D signal then point out viewers wear 3D glasses to watch, and confirm to carry out 3D and show.
Embodiment 2:
As shown in Figure 2; Need make amendment to original video lead frame; The signal that one or one field of reservation identifies input in original video lead frame form is 2D signal or 3D signal, when decoding, judges that through the position (3D flag) or the field of this special use of identification input signal is 2D signal or 3D signal then.
Claims (3)
1. 3D signal automatic-identifying method; It is characterized in that; Comprise the steps: to select to adopt the 3D video of left and right sides form; Extract the profile information of each frame left-and right-eye images of video respectively, calculate the similitude of right and left eyes image outline information, judge that according to similitude input signal still is the 3D signal for the 2D signal.
2. a kind of 3D signal automatic-identifying method as claimed in claim 1 is characterized in that: if to judge input signal be the 3D signal then point out the viewers wear glasses to watch, and confirm to carry out 3D and show.
3. 3D signal automatic-identifying method; It is characterized in that; Comprise the steps: that the signal that one or one field of reservation identifies input in original video lead frame form is 2D signal or 3D signal, when decoding, judge that through position or the field of discerning this special use input signal is 2D signal or 3D signal then.
