Embodiment
Further to illustrate the present invention to reach the technological means and effect that predetermined purpose is taken, below in conjunction with accompanying drawing
And preferred embodiment, the present invention is described in detail as after.
Fig. 1 is the flow chart of the method authenticated by image of the embodiment of the present invention.As shown in figure 1, this method bag
Include following steps：
Step 101：Two cameras of control terminal are shot respectively, obtain two images；
Step 102：Judge whether two images meet preparatory condition；
In this step, judge whether two images meet preparatory condition and can specifically include：Judge two got
Whether image matches with pre-setting reference picture corresponding with two cameras respectively；If, it is determined that two images are expired
Sufficient preparatory condition, otherwise, it determines two images are unsatisfactory for preparatory condition.That is, judge successively the image that photographs whether with shooting
Reference picture matching corresponding to the camera of the image.Moreover, it is judged that the image photographed whether with corresponding reference picture
Matching needs to carry out image recognition to the image photographed, will get the texture progress pair of the texture and reference picture of image
Than to judge whether two images belong to same object.
Wherein, two cameras of terminal are located at the same side of terminal, based on this, judge whether two images meet default
Condition can also be realized according to following processing：
Judge whether two images match with pre-setting two reference pictures corresponding with two cameras respectively；
In the case that two images are matched with two reference pictures pre-set respectively, according in the prior art according to two cameras it
Between distance and two images focal length, calculate the distance between corresponding material object of two images；Judge two images pair
Whether the distance between material object answered is in the range of pre-determined distance；If, it is determined that two images meet preparatory condition, if it is not,
Then determine that two images are unsatisfactory for preparatory condition.
Step 103：In the case where two images meet preparatory condition, it is determined that authenticating successfully, scheduled operation is performed.
Wherein, the object captured by two cameras includes：Fingerprint or eyes, preset reference image are shot with camera
Image correspondence, it is necessary to explanation, fingerprint or eyes recited herein is only a preferred mode of the embodiment of the present invention,
Object captured by two cameras can be two with the fixed range object or scene being arbitrarily designated.
Wherein, scheduled operation is specifically as follows：The unblock operation of terminal or the application interface for entering setting, wherein, setting
Application interface be application interface corresponding with the image that camera is photographed, can be with for example, after the image of fingerprint is photographed
The interface of a certain application-specific is directly entered, the operation for automatically beginning to application is realized.
Fig. 2 is the flow chart of the method authenticated preferably through image of the embodiment of the present invention.As shown in Fig. 2 should
Method comprises the following steps：
Step 201：Reference picture is gathered, the characteristic parameter of reference picture, and the corresponding reality of two reference pictures is obtained
The distance parameter of thing；
Step 202：Judge whether the first camera collects qualified object picture, if it is, performing step
203, if not, terminating flow；
Step 203：Judge whether second camera collects qualified object picture, if it is, performing step
204, if not, terminating flow；
Step 204：Calculate the corresponding distance in kind of photo of two cameras shooting；
Step 205：Judge whether the corresponding distance in kind of photo that two cameras are shot meets pre-determined distance, if
It is to perform step 206, if not, terminating flow.
The object for authentication is the finger of user below, and the operation of authentication successful execution is that unblock operation is
Example, focusing image pickup method multiple to dual camera provided in an embodiment of the present invention is briefly described.
First, two specified fingers are placed on before two cameras of terminal by user, and two cameras of terminal are carried out
Shoot, get a finger for showing user in two images, the two images respectively, camera calls image recognition mould
Block, picture recognition module obtains the fingerprint texture feature of user in two pictures, with gather and preserve in advance two of user
The textural characteristics of fingerprint are contrasted respectively, if comparing result shows, the fingerprint in two images is same with preset fingerprint
One fingerprint, then calculate two fingers of the user for authentication according to the focal length of the distance of the camera of terminal two and two images
Between actual range, by obtained distance values with advance gather or preserve distance values compared with, it is assumed that default two
The distance between finger scope is that, more than or equal to 5 centimetres, terminal calculates when obtained distance is more than or equal to 5 (such as 6 lis
Rice), authenticate successfully, calculate obtained distance and be less than 5 centimetres (such as 3 centimetres), then failed authentication.In the case of authentication is successful,
In the case of notifying that terminal performs unblock operation, failed authentication, any operation is not performed.
