It is well known that outside environmental elements can directly or indirectly influence to capture picture quality, such as light intensity, camera terminal
Shake, distance of shooting distance etc., the quality of shooting image can be reduced to some extent.
However, in the shooting kind equipment course of work, it is difficult to avoid the interference of outside environmental elements described above, such as it is cloudy
The light intensity of rainy day is less than fine day, is equally indoor, the light intensity in subway is less than in high building；For example shake, someone
The reason for for hand shaking, also there is extraneous factor to cause the reason for carrier of ground or placement image unit 30 is shaken；For example clap
The distance of photographic range, on the one hand can cause focusing difficult, on the other hand, even if image unit 30 has automatic focusing function, still can
Cause the facial image captured bigger than normal or less than normal, be not easy to system identification checking.
From the foregoing it will be appreciated that usual solution is using software compensation method or uses taking the photograph for higher performance instead
As head, this can undoubtedly bring the increase of cost, the complexity of program.
Therefore, present inventive concept improves external environment from hardware point of view, makes external environment parameters be adapted to capture best effective
The facial image of fruit, it is ensured that on the premise of picture quality, reduces the requirement to camera and image processing software.
And the premise for improving external environment is to obtain and judge whether outside environmental elements meet the requirements, and which environment
Parameter is undesirable.
With reference to Fig. 1, the present invention refers to a kind of recognition of face checking terminal that can adapt to different application scene, and the face is known
Not Yan Zheng terminal include shooting button 10, image unit 30, ambient parameter collecting unit 50, memory cell 40 and processing unit
20。
In the present embodiment, we are provided with a shooting button 10 in the structure, to make user grasp the opportunity shot,
Shooting button 10 is pressed to enter photographing program, the recognition of face checking terminal of this spline structure is when actively selecting to shoot by user
Carve and reference object.
In another embodiment, after recognition of face checking terminal is opened, it will enter continuous firing state, this is required
Another human body sensing unit is set, enters the shooting area specified to sense someone, this human body sensing unit can be used
Infrared sensor etc..
For the ease of illustrating, in example referenced below exemplified by actively selecting shooting time and reference object by user
Recognition of face checking terminal structure be defined.
Shooting button 10 is electrically connected with processing unit 20, and user is pressed after shooting button 10, and processing unit 20 first generates one
Instruction is shot, image unit 30 shoots the image of designated area, at the same time, and it is current that ambient parameter collecting unit 50 starts collection
Ambient parameter.
In this example embodiment, we have chosen three kinds of ambient parameters：Light intensity, the vibration values of image unit 30, image unit 30
With the distance of reference object, for these three ambient parameters, aforesaid environmental parameters unit should at least include light intensity sensor 51,
Vibrating sensor 52 and range sensor 53, respectively to detect the light intensity in specified shooting area, image unit 30 vibration
The distance of value and image unit 30 and reference object, and result of detection can be fed back to processing unit 20, it is single for processing
Member 20 is with reference to application.
For the simplicity of description, in example below, we only choose influences larger light intensity and vibration to picture quality
Value introduces the method for work that terminal is verified in the recognition of face as factor of influence.
There is provided first has a personal information database in a memory cell 40, memory cell 40, to record some tools
Targetedly face information.
Shooting unit 30 is pressed in response to shooting button 10, shoots the image of designated area, at the same time, light intensity sensing
Device 51 gathers the light intensity value Es of shooting time shooting area, the vibration values of the collection shooting time of vibrating sensor 52 image unit 30
Df。
Based on the light intensity value Es, pass through formulaComputing environment shadow rings factor S1, wherein, E0For can
Shooting effect is set to reach optimal light intensity value.
Based on the vibration values Df, pass through formula S2=DfCalculate vibration effect factor S2。
Based on the light intensity value Es and vibration values Df, pass through formulaCalculate comprehensive ring
Border factor of influence S.
From formula, ambient light factor of influence S1What is represented is the inclined of actual light intensity and the optimal light intensity values of shooting time
From degree, deviate more, the shooting effect of image unit 30 is poorer；S2=Df, vibration effect factor S2What is chosen is exactly vibration values
Itself, because no matter from theoretical or reality, vibration values Df is that shooting effect is optimal for 0, and vibration values Df is bigger, image unit 30
Shooting effect it is poorer.
The present invention sets two threshold values, the first given threshold and the second given threshold, and provides as follows：When environment shadow
Ring factor S1More than the first given threshold or vibration effect factor S2During more than the second given threshold, judge that this shoots outer
Boundary's ambient parameter is undesirable, and shooting image is second-rate, not uses, and generates alarm signal, reminds user to repair as early as possible
Positive ambient parameter.
Under some application scenarios, although ambient light factor of influence S1With vibration effect factor S2All meet sets requirement, but
Be two factors of influence numerical value it is all larger, under both collective effects, the quality of shooting image is still poor, therefore, I
Propose Comprehensive environmental factor S and the 3rd given threshold this setting, Comprehensive environmental factor S is influenceed based on ambient light
Factor S1With vibration effect factor S2Get, even if ambient light factor of influence S1With vibration effect factor S2Demand is met, but it is comprehensive
Environmental Factors S is more than the 3rd given threshold, and processing unit 20 still can judge that external environment parameters are undesirable, shoots
Picture quality is poor, not uses, and generates alarm signal.
As foregoing ambient light factor of influence S1, vibration effect factor S2When all being met the requirements with Comprehensive environmental factor S,
Processing unit 20 judges that external environment parameters meet the requirements, and it is single that the image that now can just shoot image unit 30 is stored in storage
Member 40, and face recognition software is called, face information is identified from image, the face information and personal information that will identify that
Face information in database compares, and generates comparison result, that is, the object shot whether there is in personal information database,
And/or be personal information database who etc..
Distance parameter is also that first analysis judges the distance of collection it is also possible to gather distance parameter by range sensor
Whether parameter meets the distance threshold of setting, if do not met, and generates alarm signal, if met, in conjunction with light intensity, vibration
Value is analyzed together, more ambient parameter collections and analysis method can be introduced what is more, therefore not to repeat here.
Method of work more than, we can be by analyzing the external environment parameters of shooting time, it is determined that shooting
Image can be used, and the accuracy that terminal is verified in recognition of face is improved from another angle.
Recognition of face checking terminal mentioned by the present invention also includes a display unit 80, display unit 80 and processing unit
The generational verctor of alarm signal is informed user by 20 electrical connections, processing unit 20 in response to alarm signal by display unit one,
The generational verctor of alarm signal includes：1) ambient light factor of influence S1More than the first given threshold, 2) vibration effect factor S2It is more than
Second given threshold, 3) Comprehensive environmental factor S is more than the 3rd given threshold, is which environment to help user quickly to determine
Parameter does not meet demand, targetedly corrects ambient parameter.
The display unit 80 is also to show comparison result, so that user checks.
This display unit 80 can be same with the display screen of image unit 30, can also be separately provided, it is therefore an objective to
The working condition of recognition of face terminal and the ambient parameter of shooting area can be shown at any time.
Further, when comparing successfully, in order to point out user, recognition of face checking terminal also has a voice message list
Member 70, voice alerting unit 70 is electrically connected with processing unit 20, and the processing unit 20 is configured to the bat in response to receiving
The personal information comparing success taken the photograph in image and personal information database, generates cue, the voice alerting unit
70 are configured to, in response to cue, send voice message.
Voice alerting unit 70 can also send corresponding voice message to point out to use when external environment is undesirable
Whether family, points out which ambient parameter of user undesirable, and/or have been taken completing.
The present invention further mentions some modes and carrys out adjusting ambient parameter.
Improve light intensity most efficiently method be no more than by light source adjust, in this application, recognition of face verify terminal
Also there is a luminosity compensation unit 60, luminosity compensation unit 60 includes the light source that several distributions are set, it is preferred that these light
Source is that light intensity is adjustable.
Optionally, light source is arranged on a rotatable pedestal correspondingly, to realize the change of light source radiating angle,
Further increase the degree of regulation of environmental light intensity.
The switch and light intensity regulating of light source have two ways, and one is that user is manually operated, and one is that processing unit 20 is automatic
Operation.
From practical operation meaning angle, processing unit 20 is automatically brought into operation more hommization, and processing unit 20 receives light
Strong sensor 51 feed back on the light intensity parameter in designated area, it is made comparisons with permission range of light intensity set in advance,
Permission range of light intensity herein is that can shoot the range of light intensity of high quality graphic, if the light intensity parameter in designated area
Beyond range of light intensity is allowed, illustrate that light intensity now is not suitable for taking pictures, it is necessary to improve photoenvironment.
Part light source, the regulation intensity of light source, direction of illumination etc. are closed or opened to processing unit 20 according to comparative result, until
The result of detection that light intensity sensor 51 feeds back, which falls, to be allowed in range of light intensity or untill closing on optimal light intensity values.
As for vibration values, in order to reduce shake caused by artificial origin, image unit 30 can be fixed on to a support frame
On, and external environment caused by shake, such as support frame in itself shake, then it is reluctant many, in the prior art generally
Selection is adjusted by software approach, and slight shake can be by simple image processing software to improve, and shake
When amplitude is larger, simple image processing software then turns turtle.
Rule of thumb understand, the vibration values of image unit 30 are generally not a constants, it be over time it is variable,
For this, we can set pre- shoot and instruct.
Processing unit 20 is generated after pre- shooting instruction, sends an instruction to vibrating sensor 52, vibrating sensor 52 starts
The vibration values of image unit 30 are gathered, if now the vibration values of image unit 30 have exceeded default permission oscillating region, place
Reason unit 20 will not do shooting action, continue to monitor the vibration values of image unit 30, until in a certain moment or certain time period
The vibration values of image unit 30 are allowing within oscillating region, and light intensity now also complies with requirements, and the shooting of generation one refers to
Order, control image unit starts shooting image.
Herein, the detection of vibration values is placed on after the pre- shooting instruction of generation, it, because if not shooting demand, is or not
The vibration values of detection image unit 30 are needed, movement occurs in image unit 30 unavoidably in use, not shooting needs
Has no practical significance after vibration values detection when asking.
The detection of light intensity can equally use such scheme, that is, be placed on after the pre- shooting instruction of generation, but the tune of light intensity
Section has its particularity, there is such a case, filming frequency is very high, and light intensity value is undesirable, if using class
The scheme of vibration values is similar to, primary source will be switched by often generating once shooting instruction, be to cause damage to light source and human eye,
Therefore the regulation of light intensity can be arranged on after recognition of face checking terminal starts working, and unrelated whether generated shooting and referred to
Order.Generation on shooting instruction, suitable light intensity is one of necessary condition.
The distance of image unit 30 and reference object, can in several ways realize, for example, pacify image unit 30
It is arranged on a guide rail, or by image unit 30 on a telescope support 72.Processing unit 20 receives range sensor
The result of detection of 53 feedbacks, finds result of detection beyond distance range is allowed, the control that generation one adjusts distance refers to after comparison
Order.
A motor 71, by taking telescope support 72 as an example, motor 71 and telescope support are additionally provided with recognition of face checking terminal
72 connections, are electrically connected with processing unit 20, and the control instruction of the adjustment distance that motor 71 is generated according to processing unit 20 is to drive
Telescope support 72 stretches, so as to adjust the distance between image unit 30 and reference object.
Member in personal information database sets according to the actual requirements.
For example, under a kind of application scenarios, comparing successful personnel and being allowed through gate, then personal information database
In member be allow by the staff list by gate.
Under another application scenarios, compare successful personnel and belong to black list member, when comparing successfully, it is preferred that
Processing unit 20 will generate an alarm signal, to drive an alarm unit to send alarm, send warning information to monitoring
On the mobile phone or display screen of personnel, monitoring personnel is reminded to handle this case in time.
The capacity of memory cell 40 is limited after all, and information also constantly updating, in addition, recognition of face terminal
If non-handheld, the setting of its parameter can be realized by other-end and can more facilitated.
Therefore, the application proposes to set a network communication interface in recognition of face checking terminal, network communication interface with
Processing unit 20 is connected, to by recognition of face accessing terminal to network, to realize recognition of face terminal and other-end or cloud
Hold the data communication of server.
So as to which the present invention refers to a kind of recognition of face checking terminal that can adapt to different application scene and its work side
Method, judges whether outside environmental elements of the recognition of face checking terminal in shooting image meet sets requirement, if extraneous ring
Border factor meets the requirements, then directly uses, if outside environmental elements are undesirable, points out user to correct as early as possible, to carry
The quality of terminal taking image is verified in high recognition of face.
Although the present invention is disclosed above with preferred embodiment, so it is not limited to the present invention.Skill belonging to of the invention
Has usually intellectual in art field, without departing from the spirit and scope of the present invention, when can be used for a variety of modifications and variations.Cause
