Embodiment
In embodiments of the invention, gather the mouth image of user, and record the data of described mouth image; The data of described mouth image and the data being used for triggering the mouth image of taking pictures prestored are compared, if both match, then takes pictures.
Below in conjunction with drawings and the specific embodiments, the present invention is described in further detail.
Fig. 1 is the photographic method realization flow schematic diagram based on Mouth-Shape Recognition described in the embodiment of the present invention, and as shown in Figure 1, the method comprises:
Step 101: the mouth image gathering user, and record the data of described mouth image;
Be specially: first user can open the Mouth-Shape Recognition exposal model of mobile terminal, during application, mobile terminal by the image of camera collection user, and carries out the location of mouth image, obtains mouth image; Afterwards, by the described top edge of mouth image determination upper lip and the lower limb of lower lip, and the coordinate information of the top edge peak of described upper lip and the lower limb minimum point of lower lip is recorded; Coordinate information measurement according to the top edge peak of described upper lip and the lower limb minimum point of lower lip obtains the data of lip opening and closing degree, and with the data of lip opening and closing degree described in the form record of time shaft, obtain the vocal print characteristic of the lip being similar to sound waveform.Wherein, the time interval of the data of described record lip opening and closing degree can be set to 0.05s, that is: record the data of a lip opening and closing degree every 0.05s, forms a two-dimensional curve figure.
In embodiments of the invention, the data of described mouth image are: the vocal print characteristic of lip.
As described above, in an embodiment of the invention, the vocal print characteristic of described lip is: with the data of the lip opening and closing degree of the form record of time shaft; The data of described lip opening and closing degree obtain according to the coordinate information measurement of the top edge peak of upper lip and the lower limb minimum point of lower lip.
Certainly, except the data of the lip opening and closing degree of aforesaid way acquisition, in another embodiment, the vocal print characteristic of described lip can also be: with the data of the lip overall profile of the form record of time shaft; The preparation method of the data of described lip overall profile is: measure the coordinate information of the sampled point that the top edge of whole upper lip and the lower limb of whole lower lip are arranged, obtain the data of described lip overall profile.Here, the data of the lip overall profile of the form record of described time shaft can store in a graphical form, namely the data of the lip overall profile of different time storage form a width lip overall profile figure, so, when follow-up data of carrying out mouth image compare, can compare described lip overall profile figure.
Step 102: the data of described mouth image and the data being used for triggering the mouth image of taking pictures prestored are compared, if both match, then takes pictures;
Be specially: mobile terminal is by the vocal print characteristic recording the lip obtained and the data being used for triggering the mouth image of taking pictures prestored, that is: with comparing for the vocal print characteristic triggering the lip of taking pictures of prestoring, if both match, be then that the match is successful, can action of taking pictures be performed.
Here, allow to there is certain error in the process compared, such as: the vocal print characteristic of the lip that synchronization records differs with the vocal print characteristic of the lip stored and is all considered as both ± 5% and matches.
The embodiment of the present invention, based on Mouth-Shape Recognition technology, is a kind of contactless exposal model, can effectively avoid existing pressing to take pictures body shake that key causes, improves the shooting quality of photo; Meanwhile, the embodiment of the present invention by the impact of environment, even if in a noisy environment, can not be taken to obtain high-quality photo equally, improve Consumer's Experience.In addition, the embodiment of the present invention meets the demand of taking pictures of physical disabilities and crackjaw user equally.
Preferably, in an embodiment of the invention, the method also comprises: gather that user arranges for triggering mouth image corresponding to the shape of the mouth as one speaks of taking pictures, record and store the data of described mouth image; Concrete,
User enables the Mouth-Shape Recognition mode of learning of mobile terminal, and user, in the face of camera, says for triggering the language of taking pictures, and in the process, mobile terminal gathers the image of user, and carries out the location of mouth image, obtains mouth image; By the described top edge of mouth image determination upper lip and the lower limb of lower lip, and record the coordinate information of the top edge peak of described upper lip and the lower limb minimum point of lower lip; Coordinate information measurement according to the top edge peak of described upper lip and the lower limb minimum point of lower lip obtains the data of lip opening and closing degree, and with the data of lip opening and closing degree described in the form record of time shaft, obtain the vocal print characteristic of the lip being similar to sound waveform, and store the vocal print characteristic of described mouth.
In addition, consider that photographer is generally the user of mobile terminal, that is: the shape of the mouth as one speaks person of setting and photographer are generally same person, therefore, when carrying out the comparison of vocal print characteristic of lip in a step 102, do not consider temporal difference, that is: think that the shape of the mouth as one speaks person of setting is identical with the word speed of photographer.
Visible, the typing triggering the data of mouth image corresponding to the shape of the mouth as one speaks of taking pictures described in the embodiment of the present invention only needs to perform once, in later stage use procedure, only otherwise replacing user, then directly enter Mouth-Shape Recognition exposal model to carry out taking pictures, simple and convenient user operation.
