In order to illustrate technical solutions according to the invention, illustrated below by specific embodiment.
Fig. 1 is the implementation process schematic diagram of the method for the test fatigue strength that one embodiment of the invention provides, as shown in the figure
This method may comprise steps of：
Step S101, the image that camera is gathered with predetermined time interval is obtained, is obtained from the described image gathered every time
Take ocular image.
In embodiments of the present invention, the camera can be display screen front camera, and user uses and carries display screen
Electronic equipment when, camera gather user image, in order to obtain the fatigue strength of user in real time, can adopt in real time
Collect image, such as at predetermined intervals, when time interval is sufficiently small, equivalent to real-time image acquisition.Collect image
Afterwards, it is necessary to obtain ocular image from the image of collection.Specifically the process of acquisition ocular image is：Detection collection
Whether there is face in image, if detecting face, continue to detect ocular in Face datection frame, if can't detect people
Face, then the image is abandoned.Further, since user is moved during using electronic equipment it is possible that adjusting posture etc.
Make, so the image of collection is it is possible that unsharp phenomenon, we can after gathering image, detect after face or
Judge whether image is clear after obtaining ocular, if clearly, continuing subsequent operation, the direct discarding image if unintelligible.
Step S102, extracts the characteristic information of iris in the ocular image, and by the spy of the iris of extraction
Reference breath is matched with the characteristic information of the iris prestored, obtains the registration of both matchings.
In embodiments of the present invention, can be according to the image zooming-out iris of ocular after obtaining ocular image
Image, the characteristic information of iris, the reading point of about 266 units of an iris are then extracted, and iris is given birth to as human body
Thing information and the state of mind of people have much relations, so can accurately be surveyed very much using the larger iris of information content is carried
Measure the fatigue strength of user.We can prestore an iris and be used as with reference to iris, and the iris gathered every time is with being used as reference
Iris be compared and obtain the two registration, the characteristic information for specifically comparing iris obtains registration.It is described advance
The iris of storage can be iris of the user of collection in the state of rest is good, then in the state of being rested according to user
The characteristic information that iris obtains is exactly the characteristic information of the iris of reference；It is described to take the photograph after can also be that user opens electronic equipment
As the iris in the image that is gathered for the first time in image that head is gathered with predetermined time interval, the posture due to user, dynamic is considered
Make etc. to influence, the image that may gather for the first time is simultaneously unintelligible, we can set first that camera collects meet it is pre-
If iris of the iris of condition as the iris prestored, that is, complete display, first rainbow for meeting preparatory condition
Characteristic information of the characteristic information of film as the iris prestored.
Step S103, the fatigue strength of user is obtained according to the registration.
In embodiments of the present invention, due to the biological characteristic of iris, iris may occur larger after human fatigue
Change, as the time of user's viewing electronic equipment display screen is longer, the change that iris occurs is bigger, then the feature letter of iris
The registration for the characteristic information of iris for ceasing and prestoring will be smaller, and we can set the scope of registration numerical value, be
One fatigue strength of each range set, for example, fatigue strength can be arranged to slight fatigue, moderate fatigue, severe fatigue.If
Fatigue strength is set into three scopes, corresponding just to need registration also to be set three scopes, the coincidence number of degrees in each scope
According to a corresponding fatigue strength, fatigue strength can also be arranged to specific numerical value, according to the spy of iris in the image currently gathered
The registration that reference ceases the characteristic information of the iris with prestoring generates specific fatigue strength numerical value.
In a particular application, after the fatigue strength for obtaining user, can also be sent according to the fatigue strength of user prompting message or
Person switches mode of learning.
If the fatigue strength of the user is more than fatigue threshold, prompting message or switching mode of learning are sent.
Different operations can also be made according to different fatigue strengths.In concrete application, it can be determined that fatigue strength and fatigue
The relation of threshold value, can also be according to the fatigue conditions of fatigue strength, for example, slight fatigue, moderate are tired so as to make different operations
Labor, severe fatigue make different operations.Specific operation includes prompting message, for example, voice reminder, vibration reminding, can be with
Alert, the pattern of current electronic equipment can also be switched, such as entertainment mode is switched into mode of learning.Can be with
By the fatigue strength of user compared with fatigue threshold, both registration (spies of the iris in the image of collection can also be used
The characteristic information of reference breath and the iris prestored) compared with registration threshold value, it is not limited herein.
In practice, we can set several fatigue thresholds (registration threshold value), corresponding different fatigue threshold section (weight
Right threshold interval), select different operations：Prompting message is sent, sends a warning, switch mode of learning.
As further embodiment of this invention, the fatigue strength that user is obtained according to the registration includes：
According to the characteristic information of iris in the image currently gathered and the registration of the characteristic information of the iris prestored
And the testing time obtains the fatigue strength of user.
In embodiments of the present invention, after user opens electronic equipment, or after receiving predetermined instruction, on electronic equipment
Camera start to gather image, and start timing.Can be according to the feature of iris in the time of timing and the image of collection
The registration of information and the characteristic information of default iris obtains the fatigue strength of user, because, the biology of everyone iris
Characteristic might have difference, and presumable people starts fatigue afterwards for a period of time using electronic equipment, but the spy of the iris of user
Reference ceases is also greater than threshold value, or the fatigue obtained according to registration with the registration of the characteristic information of the iris of collection for the first time
Degree is also less than fatigue threshold, at this moment will consider user and be determined whether using the time of electronic equipment and the fatigue strength of user
Send prompting message, warning message or switching mode of learning.In practical application, due to the change that content in screen is unexpected,
The suddenly change that can cause iris is possible to, this is possible to the characteristic information and first rainbow of iris in the image that currently gathers
The registration of the characteristic information of film is very low, and system will judge active user by accident and come into fatigue state, so we need
The registration binding test time is determined into the current fatigue strength of user.The characteristic information of the iris currently gathered with advance
The registration of the characteristic information of the iris of storage is exactly actually the registration of the iris currently gathered and the iris prestored.
As a citing, very first time threshold value, the second time threshold and the first registration threshold value, the second registration are set
Threshold value, when tested between illustrate that user comes into fatigue state when being more than the second time threshold；When the registration of iris is more than
Illustrate that user comes into fatigue state during the second registration threshold value；In very first time threshold value and the second time threshold between when tested
Registration illustrates that user comes into fatigue state between the first registration threshold value and the second registration threshold value simultaneously between value.
Certainly, in actual applications, other methods that human fatigue degree is determined according to the registration and testing time can also be set.
The embodiment of the present invention is when user uses the electronic equipment with camera, can be gathered in real time by camera
Image, ocular image is obtained from the image gathered every time, then extracts the characteristic information of iris in ocular image,
The characteristic information of an iris or an iris can be pre-set, by the characteristic information of the iris in the image collected with
The characteristic information of the iris prestored carries out matching and obtains registration, and the fatigue strength of user is obtained according to registration, utilizes rainbow
The fatigue strength of the uniqueness of film, the iris biological determination user related to fatigue.The fatigue strength so obtained is more accurate.
Fig. 2 is the schematic flow sheet that one embodiment of step S103 in Fig. 1 provides, and this method can include as shown in the figure
Following steps：
Step S201, according to the characteristic information of iris in the image gathered every time and the characteristic information of the iris prestored
Registration and every time the time point fitting of collection image obtain the curve that changes over time of registration.
In embodiments of the present invention, the biological characteristic of iris is not only relevant with fatigue strength, can not only change with fatigue strength
And change.Effect of the iris in eyes can adjust the size of pupil, so as to which the number of intraocular light adjusted.So work as screen
When light becomes strong suddenly in curtain, iris will adjust pupil and diminish so that the light into inside ofeye tails off, when light in screen
When line is dimmed suddenly, iris can adjust pupil and become big, so that the light into inside ofeye becomes more.Iris adjusts pupil
During the size in hole.Iris can change, then the characteristic information of iris can also change, but user watches by display screen
During the contents such as video, object for appreciation game, light is not unalterable.Therefore, we are designed according to rainbow in the image gathered every time
With the registration of the characteristic information of iris that prestores and every time, the time point fitting of collection image obtains the characteristic information of film
The curve that registration changes over time is obtained, the smooth curve being so fitted can abandon the point of registration suddenly change, that is,
The suddenly change of iris caused by light or other reasonses can be abandoned, the curve being so fitted be equivalent to be user rainbow
The registration of the characteristic information of film and the characteristic information of the iris prestored changes over time that (time is elongated, and fatigue strength also can
Corresponding increase, also corresponds to registration and changes with fatigue strength) curve.
Specifically the process for the curve that generation registration changes over time is：
First by the characteristic information of iris in the image gathered every time and the registration of the characteristic information of the iris prestored
Time point during corresponding collection image generates multiple coordinate points (time, registration), is according to iris during due to obtaining registration
Picture rich in detail obtain, unsharp image can discard, thus the point of fitting smooth curve institute reference be not completely by
According to predetermined time interval stepping., according to multiple coordinate points matched curves, x-axis is the time for we, and y-axis is registration, x-axis when
Between can be time for specifically sampling or specific sampling time and the time of first sampling difference, that is, survey
Try the time.Be fitted after smooth curve and just generate the curve that registration changes over time, in the curve of fitting the time of x-axis be
Stepping is spaced to schedule.
Step S202, obtain tangent slope of the curve in current point in time.
In embodiments of the present invention, we can only gather the image of portion of time point, according to the sampled point of a part
The curve that fitting registration changes over time；The curve of real-time update fitting can also be gathered in real time.If simply according to one
The curve for dividing the registration of sampled point fitting to change over time, then current point in time is exactly the current time, when being not necessarily sampling
Between；If the curve of collection real-time update fitting in real time, then current time point is exactly the time point of most freshly harvested image,
It is exactly the newest sampling time.After obtaining current point in time, the point generation tangent line in curve, tangent slope, tool are obtained
Body can be obtained with the mode of derivation, and the tangent slope of acquisition illustrates the current change degree of fatigue strength.
Step S203, according to corresponding to current point in time registration and the curve current point in time tangent line it is oblique
Rate obtains the fatigue strength of user.
In embodiments of the present invention, registration illustrates the situation of change of presented iris, and tangent slope illustrates coincidence
The situation of change of degree, just look like be speed and acceleration relation, it is assumed that registration corresponding speed, then acceleration just correspond to cuts
Line slope.So we may be referred to the situation of change of registration and registration to determine the fatigue strength of user.Certainly in reality
In the application of border, can also registration corresponding to the current time and the curve current point in time tangent slope
On the basis of be further added by the fatigue strength that parameter (testing time) obtains user, i.e., using three parameters (registration, tangent line it is oblique
Rate, testing time) determine the fatigue strength of user.
The embodiment of the present invention relative to the embodiment shown in Fig. 1 refined according to the characteristic information of iris in image with advance
The method that the characteristic information of the iris of storage obtains the fatigue strength of user, the embodiment of the present invention according to the biological characteristic of iris not
Only choose the characteristic information of the iris in the image of current time collection and overlapping for the characteristic information of the iris prestored
Degree goes to judge the fatigue strength of user, also abandons the suddenly change of registration caused by the suddenly change of iris, bent with fitting
The mode of line removes the sampled point of non-regularity, and the registration for the current sampled point being achieved in that more meets the change of iris
Rule, it is also contemplated that the situation of change of the registration of current point in time iris, utilizes the registration of iris and fitting bent
Line obtains the fatigue strength of user in the tangent slope of current point in time.
It should be understood that the size of the sequence number of each step is not meant to the priority of execution sequence, each process in above-described embodiment
Execution sequence should determine that the implementation process without tackling the embodiment of the present invention forms any limit with its function and internal logic
It is fixed.
