Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other without creative efforts
Embodiment shall fall within the protection scope of the present invention.
The control for carrying out the time of eyeshield is needed to there is inaccurate technical problem to solve above-mentioned to user, in a reality
It applies in example, spy proposes a kind of method prompting user's progress eyeshield by intelligent glasses, and the execution of this method can be dependent on meter
Calculation machine program, the computer program can run on the computer system of von Neumann system, which is intelligence
The wearable devices such as glasses.
Specifically, in the present embodiment, prompting user to carry out the method for eyeshield as shown in Figure 1, including by intelligent glasses：
Step S102：Target image is obtained by camera, searches foreground target corresponding with target identification region.
Target image is the scene image that user is observed by intelligent glasses, in the present embodiment, the target image
It is obtained by the cameras of intelligent glasses, target image includes to have powerful connections and foreground target, and in the acquisition of target image
Background area and foreground target region are identified in journey.Such as in application scenarios shown in Fig. 2, exhibiting pictures are to pass through camera shooting
The target image A that head obtains, wherein the region marked as 1,2,3,4,5 is the foreground target region in target image.
Target identification is that user is preset, the identification information for the target searched required for containing, if for example, user
The time for needing to control its using terminal electrical screen by intelligent glasses, then preset needed for the target searched be terminal
Electronic display, such as mobile phone screen, computer monitor, video screen, the terminal that target identification is searched required for containing
Electronic display identification information.
In the present embodiment, if the preset target of user is the electronic display of terminal, lookup and target identification
Corresponding foreground target region is the image for searching the electronic display in target image, in the application scenarios that Fig. 2 is provided,
As 2 corresponding foreground target region of label；If the preset target of user is books, search corresponding with target identification
Foreground target region is the corresponding image of books searched in target image, as 5 corresponding foreground target region of label.
In target image A, labeled region is not exactly background area.
Step S104：Obtain relative position of the foreground target region in the target image.
Foreground target region is that multiple pixels in target image form, and the position in foreground target region is pair
The coordinate for the pixel answered.Such as：Corresponding coordinate (x px, y px) is x-th lateral of pixel column and y-th longitudinal of picture
Plain row intersects the position of the pixel at place.
In the present embodiment, it is also necessary to which the coordinate of pixel is converted into relative position.For example, if target image is 1280
× 960 image, i.e., laterally have 1280 pixel columns, longitudinally have 960 pixels pair, then certain pixel coordinate (500px,
460px) corresponding relative position is (500/1280,460/960).It should be noted that in the present embodiment, needing to obtain institute
State the relative position of each pixel in foreground target region.
Step S106：Foreground target region is detected to exist and at a distance from target image central point less than the of first threshold
One duration.
If as shown in figure 3, within the scope of the line of sight of smart mobile phone intelligent glasses, the mesh of the camera shooting of intelligent glasses
I.e. there are the imaging of smart mobile phone in logo image, which is the corresponding foreground target region of smart mobile phone.
Foreground target region is at a distance from target image central point i.e. with smart mobile phone relative to the visual field with intelligent glasses
The offset distance of central axes is directly proportional.When offset distance farther out when, then the foreground target region of smart mobile phone is in target image
Edge；When offset distance is closer, then the foreground target region of smart mobile phone is in the center of target image.And wear Brilliant Eyes
The user of mirror in normal observation, due to human eye usually by look at straight target observations object, when offset distance farther out when,
It is believed that the corresponding object in foreground target region is not the most important observation object of human eye, and it is more likely to be actually observed object
Background.
It is insensitive to pitch angle when optionally, due to human eye observation's object, and it is sensitive to horizontal-shift, therefore, offset
Distance can only consider horizontal-shift distance.That is, only calculate foreground target region in the horizontal direction of target image with
The distance of the central point of target image.
In the present embodiment, can timing sampling obtain foreground target region at a distance from the central point of target image, and
When detecting that the distance is less than first threshold for the first time, start timer and start timing, if big to the distance in certain sampling Detection
When first threshold, then the timer time is obtained, and resets the timer.When the timer time of the acquisition is first lasting
Between.
Optionally, since people is when reading a book or seeing computer display screen, it is possible to can briefly divert sb.'s attention, for example see key
Disk, equal behaviors of drinking water.In order to avoid the judgement of the first duration of above-mentioned behavioral implications, also detectable foreground target region is not deposited
Or the foreground target region at a distance from the target image central point be not less than first threshold the second duration,
When second duration is more than third threshold value, refresh the first duration of detection.
As previously mentioned, when detecting that the distance is less than first threshold for the first time, starts first timer and start timing, if
When certain sampling Detection to the distance is more than first threshold, then starts second timer and start timing, if subsequently examining again
When measuring the distance less than first threshold, then second timer is reset into timing.If in the process, detecting second meter
When device duration (be the second duration) when being more than third threshold value, then it represents that the sight offset of user is observed object and there has been
Significant period of time, therefore, the non-accidental of short duration behavior of transfer of user's sight, at this point, first timer can be obtained
Time, and reset first timer restart calculate the first duration.
Step S108：Judge whether first duration is more than second threshold, if so, generating prompt message.
Second threshold is the time threshold that user can continuously watch the foreground target attentively, which is to preset
, it can be that user is preset, can also be matching time threshold of the system according to the different set of object,
And according to the difference of the object of foreground target, which can also differ.Such as can continuously see TV time,
The time continuously read a book, the time continuously to enjoy scenery should be different between three.
In the present embodiment, if the foreground target region that detects exists and is less than the at a distance from target image central point
First duration of one threshold value be more than second threshold, that is, illustrate the degree of fatigue of the eyes of user reached need rest when
Between, system generates corresponding prompt message and reminds user at this time.It should be noted that the prompt message can be the alarm of voice
Information, or the prompt message of other forms.In other embodiments, it corresponds to and has connected in the foreground target region
When the image of the electronic display of terminal, the prompt message can also be sent to by the connection between intelligent glasses and terminal
The terminal, and by the electronic display of terminal show with this come prompt user need carry out eyeshield, to reach
The purpose of protective spectacles.
Optionally, in one embodiment, position of the foreground target region in the target image is obtained in step S104
After setting, further includes having acquisition at a distance from the foreground target, judge whether the distance belongs to preset 5th threshold zone
Between, if it is not, then generating the prompt message of adjustment distance.
In the present embodiment, acquisition is intelligent glasses at a distance from foreground target, and is referred between physical objects
Physical distance, there are many acquisition modes of distance, such as is obtained by range sensor, passes through the automatic focusing function of camera
To obtain etc..
It should be noted that in the present embodiment, preset 5th threshold interval be according to the object of foreground target not
Same and setting corresponding reference interval, for example, the best watching distance of 24 inches of TV is 3.0 meters, reference interval can
With She Zhiwei [2.5 ,+∞), i.e., watching distance should be not less than 2.5 meters, if the distance is less than 2.5 meters, need to prompt user
Watching distance is excessively close, needs to be adjusted.If with preset 5th threshold interval is belonged at a distance from foreground target, that is, indicate intelligence
The distance between glasses and foreground target need not adjust within the scope of rational；If the distance is not in preset 5th threshold
Be worth section within, that is, indicate this apart from when it is unreasonable or non-optimal, at this time with regard to need should distance be adjusted, with protect
Demonstrate,prove eyes of user comfort level, at this point, system generate adjustment distance prompt message, the information include acquisition it is existing away from
From value, best reference distance value and the relevant information of adjustment.The prompt message can remind user by voice broadcast, at it
In his embodiment, if foreground target region corresponds to the image for the terminal electronic display screen having connected, Brilliant Eyes can also be passed through
Related prompt message is sent to corresponding terminal, and the electronic display for passing through terminal by the communication connection between mirror and terminal
Show relevant distance adjustment prompt message.
Optionally, in one embodiment, phase of the foreground target region in the target image is obtained in step S104
Further include corresponding with the foreground target region in the detection foreground target region and the target image after position
The vertical range of reference point locations, judges whether the vertical range is more than the 4th threshold value, if so, generating adjustment pitching visual angle
Prompt message.
In one embodiment, when detection foreground target region is at a distance from reference point locations, detection can be entire
All pixels in foreground target region can also be central point, leftmost side point, rightmost side point or any other by user
The point of definition.Reference point corresponding with foreground target region is preset according to the difference of foreground target in target image
, and can both be set by the user, can also be the matching reference point that system is provided according to the difference of foreground target.
For example, the central point of target image can be set as reference point, central point is generally the point of user's sight direct-view.If for another example
Foreground target is computer display screen, and healthier reading angle is the 7- of 40 ° of the angle of depression or screen center below eyes
Between 10 °, then the position according to the optimal reference point of this angle is needed.For another example if foreground target is books or newspaper etc., most
Good reading visual angle is 45 °, and rational angular field of view of reading is 30-60 °, is just needed at this time according to this optimal reading angle
Its reference point is set.
In the application scenarios that Fig. 2 is provided, target image A is the image that size is 1280 × 960, before label 2 is corresponding
Scape target area is the image of computer display screen, the corresponding relative position in foreground target region got in step S104
Be (500/1280,360/960) for vertex, (500/1280,600/960), (780/1280,360/960), (780/1280,
600/960) 4 points of quadrangle, and set its detection point as the central point of rectangle, i.e., phase position for (640/1280,
480/960) point.In the present embodiment, it is (640/1280,400/960) institute that pre-defined reference position, which is relative position,
Point.Then the vertical range of the central point in foreground target region and reference point locations is 80/960, if the 4th threshold value of setting
100/960, that is, illustrate vertical range be not more than the 4th threshold value, the pitch angle that user watches the computer display screen attentively be it is suitable,
It need not be adjusted.
For another example in application scenarios given by Fig. 2, if the image in the corresponding foreground target region of target identification is book
This image, as corresponding to label 5 and the central point in the foreground target region that is got in step S104 correspond to
Relative position be (700/1280,200/960), the position of preset reference point is to think that contraposition is set in target image A
(640/1280,300/960), then the vertical range that can calculate the central point in foreground target region and the position of reference point is 100/
960, if pre-set 4th threshold value is 80/960, illustrate that vertical range is more than the 4th threshold value, user's reading
Pitch angle is unreasonable, needs to be adjusted, and to ensure the comfort level of eyes of user, then generates carrying for pitch angle adjustment
Show information, the prompt message information includes the relevant information of pitch angle adjustment.The prompt message can pass through voice broadcast
User is reminded, in other embodiments, such as in upper example, if foreground target region corresponds to the terminal electronic display screen having connected
When image, related prompt message can also be sent to corresponding terminal by the communication connection between intelligent glasses and terminal,
And show that relevant pitch angle adjusts prompt message by the display screen of terminal.
It should be noted that in the present embodiment, the calculating of the relevant information of the adjustment of pitch angle is in intelligent glasses
With consider under the premise of optimum distance at a distance from foreground target, in other embodiments, it is also contemplated that intelligent glasses with before
