The quantity of a little devices can be more etc., and the present invention does not limit this.
Fig. 2 is a schematic flow chart of the method that the testimony of a witness of the embodiment of the present invention is veritified.Method shown in Fig. 2 can be with
Electronic equipment 10 as shown in Figure 1 executes, and is specifically executed by processor 102.Method shown in Fig. 2 may include：
S110, in the case where image collecting device is in close state, if distance sensing device is in the first preset distance
Section senses object, then opens described image acquisition device；
S120, in the case where described image acquisition device is in the open state, if the distance sensing device is default
Object is not sensed in duration and the second preset distance section, then closes described image acquisition device, wherein described first is predetermined
It is the subset in second preset distance section apart from section.
It is understood that distance sensing device can be range sensor, it can be non-image sensor 114 shown in FIG. 1
One of.It is understood that image collecting device can be photographic device, such as camera, it can be imaging sensor shown in FIG. 1
One of 110.
Illustratively, distance sensing device senses object, can refer to：Distance sensing device senses pre- in front of it
If apart from section memory in object.It is understood that being compared people would generally be located at equipment to subconsciousness when carrying out testimony of a witness veritification
Front, therefore distance sensing device can sense the distance of the object in front.
In the embodiment of the present invention, distance sensing device can be mounted on to the side of image collecting device, so that distance perception
The distance for surveying the object that device is sensed is substantially equal to the distance between image collecting device and object.For example, distance perception
Surveying device can be arranged side by side with image collecting device, and the direction of object that is sensed of distance sensing device and image collector
The direction for setting object collected is consistent.
Distance sensing device can use " time-of-flight method " such as range sensor (also referred to as displacement sensor)
The principle of (flying time) carrys out the distance with detection object.It is by emitting especially short light pulse and measuring the light pulse
From the time being reflected by the object back is emitted to, the distance between object is calculated by surveying time interval.Range sensor
It is more that optical distance sensor, infrared distance sensor, ultrasonic distance sensor etc. can be divided into according to the difference of its working principle
Kind.By taking infrared distance sensor as an example, an infrared emission tube and an infrared receiver tube can have, wherein infrared
Line transmitting tube is used for receiving infrared-ray pulse for emitting infrared pulse, infrared receiver tube.
That is, distance sensing device can by send and receive wave time interval and wave characteristic (e.g., this
Kind of the aerial spread speed of wave) determine the distance of objects in front.Further, distance sensing device can according to this away from
From generation semaphore.Wherein, the obtained semaphore of distance sensing device can be the function of distance.Then, distance sensing fills
The device that the semaphore can be provided to the method shown in Fig. 2 that executes by system interface is set, such as processor 102.
In addition, due to distance sensing device sense object apart from when, be easy shadow by externally and/or internally factor
It rings, shows as also generating semaphore, signal numerical quantity is smaller at this time, therefore can ignore when object is not present in front
It filters out bottom lower than the semaphore of preset value to make an uproar interference, with the accuracy of distance determined by guaranteeing.In this way, can pass through
Exclusive segment semaphore carrys out exclusive PCR, improves the accuracy of data.
Illustratively, in S110, semaphore at least once that the available distance sensing device obtains, wherein
The semaphore is the function of the object that the distance sensing device is sensed and the distance between the distance sensing device；
According to the semaphore at least once, determine the distance in first preset distance section.
As an example, in order to reduce the probability that error occurs, what available distance sensing device returned continuously believes three times
Number amount, and judge whether to sense object in the first preset distance section according to the continuous semaphore three times.For example, if even
Continuous semaphore three times determines that there are objects in the first preset distance section in front of distance sensing device, then can determine each time
Distance sensing device senses object.That is, needing distance sensing device, continuously semaphore all meets three times in S110
It is required that can just trigger comparison logic.It is understood that can also be judged according to continuous n times semaphore, N can be greater than 3 or be less than
3, the present invention does not limit this.
That is, executing the device (such as processor 102) of method shown in Fig. 2 can receive at least from distance sensing device
One semaphore, and according to the functional relation between semaphore and distance, obtain the distance between object and distance sensing device.
Then, judge the distance whether be located at the first preset distance section in, with this come decide whether open image collecting device.
In such manner, it is possible to prevent the frequent of image collecting device caused by the sensing error due to distance sensing device from opening
It opens, so as to extend the service life of image collecting device, while can reduce power consumption.
Optionally, semaphore can be determined according to the distance of its objects in front determined by distance sensing device.As
An example, the semaphore can be equal to the distance, and the unit of the semaphore is millimeter (mm).As another example, which can be with
Equal to the inverse of the distance, the unit of the signal is 1/mm, at this time between semaphore size and object and distance sensing device
Distance is inversely.In addition, semaphore can also be the function of the other forms of distance, the present invention does not limit this.
In order to which facial image taken when guaranteeing that the testimony of a witness is veritified clearly can be used, the first preset distance area can be set
Between.Due to that can not clap full face when distance is too close, the lower limit in the first preset distance section is greater than 0；Due to apart from too far
Shi Wufa extracts the enough information of face, therefore the upper limit in the first preset distance section can not be too big.It therefore can be with
According to the attribute setup of image collecting device suitable first preset distance section, as an example, it can be assumed that its for 0.2 meter~
1.2 rice.It is understood that the first preset distance section may be other ranges, the embodiment of the present invention does not limit this.
Illustratively, in the case where described image acquisition device is in close state, front-end screen shows the standby page.
In the case where described image acquisition device is in the open state, the front-end screen shows that image compares the page.Wherein, front end
Screen is directed towards the display for the person of being compared, and the person of being compared can see that image collecting device is collected in the front-end screen
Facial image, the person of being compared can correspondingly adjust in front-end screen shown people by adjusting posture, shift position etc.
Face image.
In this way, front-end screen also shows the standby page, can further reduce function when image collecting device is closed
Consumption.
It can be seen that in S110, original state is：Image collecting device is closed and front-end screen shows the standby page.
It then can detect that there are objects in the first preset distance section based on distance detection device, and open image collecting device,
And start image and compare the page, page real-time exhibition image collecting device video flowing collected is compared in the image.
As a kind of implementation, testimony of a witness veritification can be further carried out after S110.It can be seen that the present invention is real
It applies in example, comparison process can be started according to the sensed object of distance sensing device, be manually operated without staff
(such as mouse is clicked mode and triggered) reduces triggering time-consuming, improves treatment effeciency thus, it is possible to simplify process flow.
Specifically, the facial image of face to be verified can be obtained from video flowing, and obtain additional clause body to be verified
Part image.And judge whether the face in the facial image and the identity image belongs to same people.
Illustratively, it obtains facial image and can be executed parallel with acquisition the two acquisition process of identity image and (or be
It is asynchronous to be performed simultaneously).In such manner, it is possible to make full use of the processing capacity of equipment, the total time-consuming of comparison process is effectively reduced, is mentioned
High treatment effeciency.
Illustratively, an example of the comparison process in the embodiment of the present invention can be as shown in figure 3, below in conjunction with Fig. 3 to this
Comparison process carries out more detailed elaboration.
Wherein, image collecting device facial image collected is obtained, may include：Image acquisition device is to video
Flow data；The facial image in the video stream data is determined by Face datection；Determine the quality of the facial image
Reach predetermined quality threshold；The first label is carried out for the facial image.
Referring to Fig. 3, available image collecting device video stream data collected.Then sentenced by Face datection model
Break in each frame of the video stream data with the presence or absence of face.Illustratively, it can detect whether that there are faces with frame by frame.As
A kind of implementation can return to reacquisition image if determining that face is all not present in any frame by Face datection
Acquisition device video stream data collected, and Face datection is carried out again to the video stream data of reacquisition.As another kind
Implementation can further judge through Face datection institute really if determining a certain frame there are face by Face datection
Whether fixed face meets required face quality requirement.It is understood that if determining a certain frame video fluxion by Face datection
There are more than one faces in, then can be using the nearest face of range image acquisition device as the face figure for being compared people
Picture, or can be according to detected face size using the maximum face of area as the facial image for being compared people.
If it is judged that determining that the facial image reaches predetermined quality threshold, then the first mark is carried out to the facial image
Note.If it is judged that determining that the facial image is not up to predetermined quality threshold, then the second label (figure is carried out to the facial image
It is not shown in 3).The subsequent person of being compared can adjust its position or posture etc. based on the second label, and then can resurvey people
Face image.
Illustratively, it if facial image is not detected or facial image is not up to predetermined quality threshold, can carry out
Auditory tone cues or the text prompt person of being compared in front-end screen, so that the person of being compared can adjust its opposite figure according to the prompt
As position, the posture etc. of acquisition device.And then image collecting device can reacquire video stream data, and can be based on again
The video stream data of acquisition re-executes the above process.In addition, the person of being compared can also obtain prompt information from the front-end screen,
With position, the posture etc. for adjusting its relative image acquisition device according to the prompt.
Illustratively, when carrying out Quality estimation, the horizontal direction angle of the face can be determined based on facial image, is erected
The picture qualities such as straight orientation angle, rotation angle, fog-level, brightness, and by obtained various picture qualities with it is corresponding
Predetermined quality threshold is compared.If each picture quality is all satisfied corresponding predetermined quality threshold, the people can be determined
Face image reaches predetermined quality threshold.Otherwise, a certain picture quality is unsatisfactory for corresponding predetermined quality threshold if it exists, then can be with
Determine that the facial image is not up to predetermined quality threshold.For example, if the rotation angle of facial image is greater than preset rotation
Angle threshold, illustrating the facial image not is positive face, is unsatisfactory for quality requirement.Again for example, if facial image is excessively fuzzy,
It is not able to satisfy definition quality threshold value, illustrates that the facial image is not clear enough, is unsatisfactory for quality requirement.
That is, carrying out the first label to it when the quality of facial image reaches quality threshold.When facial image
When quality is not up to quality threshold, the second label is carried out to it.Optionally, the first label can be：By the facial image
Face collimation mark is denoted as the first color.Second label can be：The face collimation mark of the facial image is denoted as the second color, and institute
The second color is stated different from first color.For example, the first color is blue, the second color is red.The present invention to this not
It limits.
After through Face datection model inspection to face, detected face area can be marked using face frame
Domain；Followed by Quality estimation, if reaching predetermined quality threshold, face frame is the first color；If not up to preset quality
Threshold value, then face frame is the second color.
It can be seen that by the process, the available facial image with the first label, for image collecting device institute
The facial image for reaching predetermined quality threshold of acquisition.
Referring to Fig. 3, available additional clause identity image to be verified can specifically be obtained by electronics reading manner
Take the identity image.
Integrated circuit can be included in certificate to be verified, such testimony of a witness verifying system can read it from the integrated circuit
Recorded in electronic information, electronic information here includes identity image.Illustratively, integrated circuit is referred to as chip
Or microcircuit etc., it can be made of wafer, the present invention does not limit this.For example, certificate to be verified can for identity card,
Social security card etc..
If electronics is read successfully, the available identity image.Additionally, it is appreciated that electronics can be passed through simultaneously
Reading manner obtains other identity informations of certificate, such as name, address.For example, it is assumed that the certificate is identity card, then obtain
Identity information may include name, nationality, address, identification card number, validity period, issuing authority etc..Assuming that the certificate is passport, then
The identity information of acquisition may include name, address, passport number, validity period, Issue At etc..
If electronics reads failure, it can further pass through optical character identification (Optical Character
Recognition, OCR) mode obtains the identity image.Illustratively, the card can be obtained by the modes such as scan or take pictures
The image of part then carries out OCR to the image of the certificate, so that parsing obtains the identity image.Additionally, it is appreciated that logical
Other identity informations that can also obtain certificate while OCR mode obtains identity image by OCR mode are crossed, such as name is lived
Location etc..For example, it is assumed that the certificate be do not have magnetic identity card, such as business card, then the identity information obtained may include name,
Work unit's title, address, telephone number etc..
Wherein, OCR can determine its shape by detecting dark, bright mode, then be turned over shape with character identifying method
It is translated into computword；I.e., it is possible to which the text conversion in paper document to be become to the image of black and white lattice using optical mode
File, and pass through identification software for the text conversion in image into text formatting, it is further edited and processed for word processor.
It can be seen that identity image can be obtained by electronics reading manner first, and in the failure of electronics reading manner
Obtain identity image by OCR mode, can guarantee obtain identity image validity, avoid as mode it is single caused by compare
To failure, treatment effeciency ensure that.
It is same it is possible to further whether be belonged to by the acquired facial image of recognition of face judgement with identity image
People.
Wherein, the algorithm of used recognition of face can be preparatory trained convolutional neural networks, and the present invention is implemented
Example the network structure of used neural network is not construed as limiting, such as can be ResNet, DenseNet, MobileNet,
Any network structure in ShuffleNet, Inception etc..
Specifically, the first eigenvector of facial image can be extracted by feature extraction network, and extract identity image
Second feature vector.The similarity between first eigenvector and second feature vector is calculated, is according to similarity determination
It is no to belong to same people.
Illustratively, this feature, which extracts network, can be the convolutional Neural net for being used to carry out feature extraction existing at present
Network, which is not described herein again.
Illustratively, the distance between first eigenvector and second feature vector can be calculated to calculate similarity.Example
Such as, which can be any one of Euclidean distance, COS distance, mahalanobis distance etc., or can be other distances, this hair
It is bright that this is not limited.After calculating distance, similarity can be calculated according to this distance.It as an example, can be by the calculating
Obtained distance is directly as similarity.As another example, similarity can be calculated again on the basis of obtaining distance.Meter
Calculating obtained similarity can be the value between 0~1.
If obtained similarity is greater than or equal to similarity threshold, the facial image and card for being compared people can be determined
Identity image in part belongs to same people, is otherwise not belonging to same people.Wherein, similarity threshold can basis in practical applications
Actual conditions are set, and the present invention does not limit this.
In addition, can be compared offline in the method that the testimony of a witness of the embodiment of the present invention is veritified, in this way without considering that network consumes
When, to further increase treatment effeciency.
The testimony of a witness verification procedure of the embodiment of the present invention can so be completed.Optionally, however, it is determined that be compared the face of people
Image and additional clause identity image belong to same people, can further include：Identity information (the name that will be obtained from certificate
Etc. information) be associated with the facial image for being compared people.For example, if being compared people is visitor (such as hotel occupancy visitor
People), then when carrying out visitor's registration, its facial image and corresponding identity information can be registered, can be reduced so artificial
Input reduces time-consuming, improves efficiency.
It can be seen that in the present embodiment the testimony of a witness veritify method, can according to the sensed object of distance sensing device come
Starting compares process, is manually operated without staff, and it is time-consuming to reduce triggering.It obtains facial image and obtains identity image
It can execute parallel, effectively reduce the total time-consuming of comparison process.In such manner, it is possible to simplify process flow, can make full use of
The processing capacity of equipment, to improve treatment effeciency.
It should be understood that comparison process illustrated in fig. 3 is only one embodiment of the present of invention, other implementations also can be used
Process is compared in example, such as serially executes two acquisition process；Such as identity figure is only obtained by electronics reading manner
As without using OCR mode；Deng.The present invention does not limit this.
As another implementation, after S110, if process cannot be compared as early as possible, S120 can be executed,
Image collecting device is closed.Specifically, in S120, initially, image collecting device is opened, and front-end screen shows image
Compare the page.Then, if not sensing object in preset duration and the second preset distance section, that is to say, can not carry out such as
Comparison process shown in Fig. 3, then can close image collecting device, and be that front-end screen returns to the standby page of display.Citing
For, if sensed in S110 only pass through once in a while or once in a while in front of distance sensing device short stay other staff,
S120 can be then executed after S110, is able to extend the service life of image collecting device in this way, and can reduce power consumption.
It so, it is possible that image collecting device long-time unlatching is avoided to lead to problems such as temperature excessively high, prevent from causing to system
Failure.And it is understood that in practical application scene, since there are the time of comparison demand is very short, most times are that do not have
The demand for thering is the testimony of a witness to veritify, therefore image collecting device can be in close state for a long time, when correspondingly screen can be long
Between show the standby page, so can greatly extend the service life of hardware, reduce energy consumption.
Wherein, preset duration can be set according to hardware requirement, usage scenario etc., for example, preset duration is 30 seconds
