Specific embodiment
To keep the purposes, technical schemes and advantages of the application clearer, below in conjunction with the application specific embodiment andTechnical scheme is clearly and completely described in corresponding attached drawing.Obviously, described embodiment is only the application oneSection Example, instead of all the embodiments.Based on the embodiment in the application, those of ordinary skill in the art are not doingEvery other embodiment obtained under the premise of creative work out, shall fall in the protection scope of this application.
It opens an account process online to simplify, this specification embodiment provides a kind of authentication information acquisition, account-opening method and dressIt sets, this method and device can be applied in any required client opened an account online.
1 to Fig. 4 D a kind of authentication information acquisition method that this specification embodiment provides is carried out in detail with reference to the accompanying drawingExplanation.
As shown in Figure 1, in one embodiment, a kind of authentication information acquisition method that this specification provides may includeFollowing steps:
Step 102 acquires the video comprising target object by photographic device, and the target object includes face and cardPart.
By taking cell phone client as an example, during opening an account online, needing to acquire a variety of certification letters relevant to target objectWhen breath, mobile phone camera can be automatically turned on, and prompts user that the face of user and certificate are directed at camera, or prompt togetherFace and certificate are respectively aligned to camera by user, collect one section of video of the face comprising user and certificate.Wherein, describedCertificate is the perfect instrument that can prove that user identity, including identity card, driver's license etc..
Optionally, during acquiring the video, user can be prompted to be respectively aligned to take the photograph by the obverse and reverse of certificateAs head, so as to not only include the direct picture of certificate in the video collected but also included the verso images of certificate.
It should be understood that there may be the video frames for only including face and packet in the collected video comprising target objectThe video frame for including certificate, there may also be the video frames for simultaneously including face and certificate.
It include at least one video frame of the target object, at least one described view in step 104, the acquisition videoThe picture steadiness index of frequency frame meets preset condition.
As shown in Fig. 2, in one example, step 104 can specifically include:
Sub-step 202 intercepts the first video frame from the video.
Under normal circumstances, it can be intercepted since first video frame of the video according to sequence from front to backTo the first video frame.
Sub-step 204, the picture steadiness index for determining first video frame.
The purpose for determining the picture steadiness index of first video frame is to carry out picture steadiness to the first video frameAssessment, to avoid occurring because the reasons such as the shake of photographic device make the first video frame unintelligible in shooting process, it is caused mostThe problem of desired authentication information can not be collected eventually.
Picture steadiness index can be the default characteristic value of image to be assessed, such as can be and calculated based on such as under typeThe fingerprint (fingerprint) of obtained image to be assessed: reducing the size of image to be assessed first, such as by image to be assessedThe size of 8*8 is narrowed down to, totally 64 pixels；Then simplify the color for reducing obtained image to be assessed, such as will be after diminutionImage is converted into 64 grades of gray level images, and all pixels include 64 kinds of colors altogether；Next the grayscale image that conversion obtains is calculatedThe average gray value of 64 pixels of picture；Then the gray value of each pixel is compared with average gray value, if the pictureThe gray value of element is greater than or equal to average gray value, then the pixel is denoted as 1, if the gray value of the pixel is less than average grayValue, then be denoted as 0.5 for the pixel, and calculate the cryptographic Hash of the corresponding ident value of each pixel (1 or 0.5), obtain 64 HashValue, which is the fingerprint of image to be assessed.
Sub-step 206 judges whether the picture steadiness index of first video frame meets preset condition, if fullFoot executes sub-step 208；Otherwise sub-step 210 is executed.
In one embodiment, can by comparing with continuous multiple video frames (including the first view of the first video frameFrequency frame) the fluctuating range of picture steadiness index whether be less than preset threshold, to determine the picture steadiness of the first video frameIndex meets preset condition.
By above for example for, can be with if picture steadiness index is the fingerprint that 64 cryptographic Hash are constitutedBy comparing two video frames adjacent two-by-two in the continuous 15 frame image (including the first video frame) after the first video frameIt is identical that whether 64 cryptographic Hash, which have 50 or more, if so, illustrating that the picture steadiness between continuous video frame refers toTarget fluctuating range is smaller, can determine that the picture steadiness index of the first video frame meets preset condition, namely determine firstVideo frame is stable.
In another embodiment, can judge whether the first video frame is stable by deep learning algorithm, this explanationThe book mode whether stable to the first video frame of assessment is without limitation.
Whether sub-step 208 judges comprising the target object in first video frame, if it is execution sub-step212, otherwise execute sub-step 210.
Specifically, face recognition technology, which can be used, and determine in the first video frame is when the target object is faceNo includes the target object；When the target object be certificate when, can by detect whether there are certificate frame or whetherThere are presupposed information (such as the information for often including in the certificates such as identification card number, name, issuing authority), determine in the first video frameIt whether include the target object.
First video frame is determined as one of at least one described video frame by sub-step 212.
Sub-step 210, the second video frame after intercepting first video frame in the video are as described firstVideo frame, and return and execute sub-step 204.It loops back and forth like this, until getting from the video comprising the target pairAt least one video frame of elephant.
Certainly, in another example, step 104 can not also specifically carry out the stability of the first video frame of interceptionJudgement, namely after having executed sub-step 202, it is directly transferred to sub-step 208, and determine first view in sub-step 208When in frequency frame including the target object, sub-step 212 is executed；It determines in first video frame and does not include in sub-step 208When the target object, sub-step 210 is executed.
Step 106, at least one video frame based on described in, acquire a variety of authentication informations relevant to the target object,A variety of authentication informations include at least two in testimony of a witness unification authentication information, face authentication information and certificate authentication information.
