Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Inaccurate technical matters is there is for solving the above-mentioned control needing to carry out the time of eyeshield to user, in one embodiment, spy proposes a kind of method of being carried out eyeshield by intelligent glasses prompting user, the execution of the method can be dependent on computer program, this computer program can run on the computer system of von Neumann system, and this computer system is the wearable device such as intelligent glasses.
Concrete, in the present embodiment, carry out the method for eyeshield as shown in Figure 1 by intelligent glasses prompting user, comprising:
Step S102: obtain target image by camera, searches the foreground target region corresponding with target identification.
Target image is the scene image that user is observed by intelligent glasses, in the present embodiment, this target image is obtained by the camera of intelligent glasses, and target image includes background and foreground target, and in the acquisition process of target image, identify background area and foreground target region.In application scenarios such as shown in Fig. 2, exhibiting pictures is the target image A obtained by camera, wherein label be 1,2,3,4,5 region be foreground target region in target image.
Target identification is that user presets, the identification information of the target of searching required for containing, such as, if user needs to control by intelligent glasses the time that it uses terminal electronic screen, the target then presetting desired seek is the electronic display of terminal, as mobile phone screen, computer monitor, TV screen etc., the identification information of the electronic display of the terminal of searching required for target identification contains.
In the present embodiment, if the target that user presets is the electronic display of terminal, then search the image that the foreground target region corresponding with target identification is the electronic display of searching in target image, in the application scenarios that Fig. 2 provides, be the foreground target region of label 2 correspondence; If the target that user presets is books, then searches the foreground target region corresponding with target identification and be image corresponding to the books searched in target image, be the foreground target region of label 5 correspondence.In this target image A, the region be not labeled is exactly background area.
Step S104: obtain the relative position of foreground target region in described target image.
The foreground target region multiple pixels be in target image form, and the position in foreground target region is the coordinate of corresponding pixel.Such as: what coordinate (xpx, ypx) was corresponding is a horizontal xth pixel column and y pixel column of longitudinal direction intersect the position of pixel at place.
In the present embodiment, also need the coordinate conversion of pixel to become relative position.Such as, if target image is the image of 1280 × 960, namely laterally have 1280 pixel columns, longitudinally have 960 pixels pair, then the relative position that the coordinate (500px, 460px) of certain pixel is corresponding is (500/1280,460/960).It should be noted that, in the present embodiment, need the relative position of each pixel obtaining described foreground target region.
Step S106: detect foreground target region and exist and be less than the first duration of first threshold with the distance of target image central point.
As shown in Figure 3, if within the scope of the line of sight of smart mobile phone intelligent glasses, then namely there is the imaging of smart mobile phone in the target image of the camera shooting of intelligent glasses, this imaging is foreground target region corresponding to smart mobile phone.
Namely foreground target region is directly proportional to the offset distance of smart mobile phone relative to the axis, the visual field to intelligent glasses to the distance of target image central point.When offset distance is far away, then the foreground target region of smart mobile phone is at the edge of target image; When offset distance is nearer, then the foreground target region of smart mobile phone is in the center of target image.And the user wearing intelligent glasses is when normal observation, because human eye is usually by direct-view target observations object, therefore, when offset distance is far away, can think that object corresponding to this foreground target region is not the topmost observation thing of human eye, and may be the actual background being observed thing.
Optionally, during due to human eye observation's object, insensitive to luffing angle, and responsive to horizontal-shift, and 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, the distance of the central point of foreground target region and target image can be obtained by timing sampling, and when detecting that this distance is less than first threshold first, start timer and start timing, if when certain sampling Detection is greater than first threshold to this distance, then obtain timer periods, and reset this timer.The timer periods of this acquisition was for the first duration.
Optionally, because people is in reading or when seeing computer display screen, likely can diverts sb.'s attention momently, such as see keyboard, the behavior such as to drink water.In order to avoid the judgement of above-mentioned behavioral implications first duration, also can detect foreground target region not exist or the distance of described foreground target region and described target image central point is not less than the second duration of first threshold, when described second duration is greater than the 3rd threshold value, refresh detection first duration.
As previously mentioned, when detecting that this distance is less than first threshold first, start first timer and start timing, if when certain sampling Detection is greater than first threshold to this distance, then start second timer and start timing, when again detecting that this distance is less than first threshold if follow-up, then second timer is reset timing.If in the process, when the duration (being for the second duration) of second timer being detected more than the 3rd threshold value, then represent that the sight line skew of user is observed thing and there has been significant period of time, therefore, the non-of short duration behavior accidentally of transfer of user's sight line, now, the time of first timer can be obtained, and reset first timer and restart calculating first duration.
Step S108: judge whether described first duration exceedes Second Threshold, if so, then generates information.
Second Threshold is the time threshold that user can watch described foreground target continuously attentively, this threshold value presets, can be that user presets, also can be the time threshold that match of system according to the different set of object, and the difference of the object according to foreground target, this time threshold also can not be identical.Such as can see the time of TV, the time of continuously reading, time of enjoying scenery continuously continuously, should be different between three.
In the present embodiment, if the foreground target region that detects exists and exceedes Second Threshold with the first duration that the distance of target image central point is less than first threshold, namely illustrate that the degree of fatigue of the eyes of user reaches the time needing to have a rest, now system generates corresponding information reminding user.It should be noted that, this information can be the warning message of voice, also can be other forms of information.In other embodiments; when the image of the electronic display of the terminal that described foreground target region correspondence has connected; described information can also send to described terminal by the connection between intelligent glasses and terminal; and being displayed by the electronic display of terminal points out user to need to carry out eyeshield with this, thus reaches the object of protective spectacles.
Optionally, in one embodiment, after step S104 obtains the position of foreground target region in described target image, also include the distance obtained with described foreground target, judge the 5th threshold interval whether described distance belongs to default, if not, then the information of adjustment distance is generated.
In the present embodiment, acquisition be the distance of intelligent glasses and foreground target, and refer to the physical distance between physical objects, the obtain manner of distance has multiple, such as, obtained by range sensor, obtained etc. by the automatic focusing function of camera.
It should be noted that, in the present embodiment, the 5th threshold interval preset is different according to the object of foreground target and corresponding reference interval that is that arrange, and such as, the best watching distance of the TV of 24 inches is 3.0 meters, its reference interval can be set to [2.5, + ∞), namely watching distance should be not less than 2.5 meters, if this distance is less than 2.5 meters, then need prompting user watching distance excessively near, need to adjust.If belong to the 5th default threshold interval with the distance of foreground target, the distance namely between expression intelligent glasses and foreground target, within rational scope, does not need adjustment; If this distance is not within the 5th threshold interval preset, irrational or non-optimal when namely representing this distance, now should distance adjust with regard to needs, to ensure the comfort level of eyes of user, now, system generates the information of adjustment distance, and this information includes the relevant information of the existing distance value of acquisition, best reference distance value and adjustment.This information is by voice broadcast reminding user, in other embodiments, if during the image of terminal electronic display screen that foreground target region correspondence has connected, by the communication connection between intelligent glasses to terminal, relevant information can also be sent to corresponding terminal, and show relevant distance adjustment information by the electronic display of terminal.
Optionally, in one embodiment, after step S104 obtains the relative position of foreground target region in described target image, also comprise the vertical range detecting described foreground target region and reference point locations corresponding with described foreground target region in described target image, judge whether described vertical range is greater than the 4th threshold value, if so, the information at adjustment pitching visual angle is then generated.
In one embodiment, when detecting the distance of foreground target region and reference point locations, detection can be all pixels in whole foreground target region, also can be central point, leftmost side point, rightmost side point or other points defined by the user arbitrarily.Reference point corresponding from foreground target region in target image presets according to the different of foreground target, and both can be set by the user, and also can be the reference point matched that system provides according to the difference of foreground target.Such as, can the central point of target setting image be reference point, central point be generally the point of user's sight line direct-view.Again such as, if foreground target is computer display screen, healthier reading angle is 40 °, the angle of depression, or between the 7-10 of screen center below eyes °, then needs the position of the reference point according to this angle optimum.Again such as, if foreground target is books or newspaper etc., best reading visual angle is 45 °, and reasonably reading angular field of view is 30-60 °, now arranges its reference point with regard to needing according to the reading angle of this optimum.
In the application scenarios that Fig. 2 provides, it is the image of 1280 × 960 sized by target image A, the foreground target region of label 2 correspondence is the image of computer display screen, relative position corresponding to this foreground target region got in step S104 is summit is (500/1280,360/960), (500/1280,600/960), (780/1280,360/960), (780/1280,600/960) quadrilateral of 4, and setting its point detected is the central point of rectangle, namely phase position is the point of (640/1280,480/960).In the present embodiment, the point to be relative position be in predefined reference position (640/1280,400/960) place.Then the central point in foreground target region and the vertical range of reference point locations are 80/960, if the 4th threshold value 100/960 arranged, namely illustrate that vertical range is not more than the 4th threshold value, the luffing angle that user watches this computer display screen attentively is suitable, does not need to adjust.
Again such as, in the application scenarios given by Fig. 2, if the image in the foreground target region that target identification is corresponding is the image of books, the relative position being central point that is corresponding to label 5 and this foreground target region got in step S104 corresponding is (700/1280, 200/960), the position of the reference point preset is think in target image A that contraposition is set to (640/1280, 300/960), the vertical range that then can calculate the central point in foreground target region and the position of reference point is 100/960, if the 4th threshold value pre-set is 80/960, then illustrate that vertical range is greater than the 4th described threshold value, the luffing angle of user's reading is irrational, need to adjust, to ensure the comfort level of eyes of user, then generate the information of luffing angle adjustment, this information of this information includes the relevant information of luffing angle adjustment.This information is by voice broadcast reminding user, in other embodiments, as in upper example, if during the image of terminal electronic display screen that foreground target region correspondence has connected, by the communication connection between intelligent glasses to terminal, relevant information can also be sent to corresponding terminal, and adjust information by the luffing angle that the display screen display of terminal is relevant.
It should be noted that, in the present embodiment, the calculating of the relevant information of the adjustment of luffing angle considers under prerequisite at optimum distance of the distance of intelligent glasses and foreground target, in other embodiments, it is also conceivable to the actual range of intelligent glasses and foreground target and the sight line of user and horizontal line line angulation.
Such as, in an application scenarios, as shown in Figure 3, user can operative intelligence mobile phone while wearing intelligent glasses, and intelligent glasses and smart mobile phone can match in advance and connect, and such as, are connected by wifi or bluetooth.After connecting, if the first duration that intelligent glasses detects the electronic display of terminal that the foreground target region correspondence in the image of shooting has connected and the distance of the central point of the image of this foreground target region and shooting is less than first threshold, transmission screen saver programs play instruction or screen out code were to described terminal when exceeding Second Threshold.
In one embodiment, if the image of the electronic display of the terminal that foreground target region correspondence has connected, namely represent that user is in this electronic display of use, and the first duration exceeded Second Threshold and describes user and use the time of this electronic display to reach certain display, now needed to carry out eyeshield.In upper example; provide the method generating corresponding information reminding user; in the present embodiment; in order to force users does not re-use electronic display; reduce the injury to eyes; effectively protect eyes, present embodiments provide a kind of compulsory measure, namely transmission screen saver programs play instruction or screen out code are to terminal.After terminal receives the screen saver programs play instruction of intelligent glasses transmission, play screen protection in described electronic display; Terminal close corresponding electronic display, thus force users can not continue to use described electronic display after receiving the screen out code of intelligent glasses transmission.
It should be noted that, the terminal be connected with intelligent glasses can have multiple, and such as intelligent glasses can connect with mobile phone, computer, TV simultaneously.Intelligent glasses send screen saver programs play instruction or screen out code to a certain terminal after, if detect, image corresponding to the foreground target region of target image is the electronic display of the terminal that other have connected, transmission screen saver programs play instruction or screen out code are to this terminal, and force users can not use the terminal device of other having electronic display screens.
In one embodiment, also comprise: the intensity being obtained ambient light by light sensor; Obtain the brightness that described foreground target region is corresponding; The intensity judging described ambient light whether with the brightness matching in described foreground target region, if not, then generate the information of adjustment light.
Concrete, the brightness of ambient light is obtained by light sensor, and brightness corresponding to foreground target region refers to the brightness of the position at place, foreground target region in the target image got, and this brightness can be obtained by camera.Whether the relative size whether both judgements mate the brightness containing both judgements is coupling, and also not identical according to the concrete decision criteria of its coupling of difference of object.Such as, if foreground target region corresponding be the image of electronic display, its ambient light should be just 3 times of screen intensity; The image of what if foreground target region was corresponding is books, then the brightness in its foreground target region just should reach the comfort level that certain preset value guarantee user uses eyes; It should be noted that, judging that decision criteria that whether brightness of the ambient light brightness corresponding with foreground target region mates can be preset by user also can be that system presets according to the situation of optimum.
If the intensity of described ambient light is not mated with the brightness in foreground target region, then illustrate that the brightness of ambient light instantly brightness that is improper or foreground target region is inappropriate, need carry out the comfort level that adjusts to ensure user's eye and ride up to protective effect to eyes, then generate corresponding light adjustment information, light adjustment information contains the brightness of current environment light, the brightness that foreground target region is corresponding, the selection of optimum coupling brightness and the related advisory information how to adjust, this information is by voice broadcast reminding user, if during the image of terminal electronic display screen that foreground target region correspondence has connected, by the communication connection between intelligent glasses to terminal, relevant information can also be sent to corresponding terminal, and by the light adjustment information that the display screen display of terminal is relevant.
In one embodiment, when also including the image of the terminal electronic display screen connected in described foreground target region correspondence further, by the described display parameter connecting the terminal electronic display screen connected described in acquisition, described display parameter comprise contrast, brightness and screen scanning frequency; Judge whether the intensity of described ambient light mates with described display parameter, if not, then generate corresponding screen display parameters adjustment instruction, and send to described terminal.
It should be noted that, intelligent glasses is wearable electronic equipment, the communication connection between itself and terminal can be set up, as the terminals such as intelligent glasses and computer, mobile phone, TV coupled together by the mode such as wireless network, bluetooth, and the mutual transmission of message therebetween can be realized by this connection.Such as in the present embodiment, after intelligent glasses and terminal are coupled together, when the terminal electronic display screen that foreground target region correspondence has connected, the relevant information of this terminal can be obtained by this connection, as the display parameter of electronic display, in the present embodiment, described display parameter contain contrast, brightness and screen scanning rate frequency.
In the present embodiment, the intensity of ambient light is obtained by light sensor.For keeping the comfort level of eyes of user, the brightness of ambient light should be 3 times of screen intensity, and screen scanning frequency should be greater than 60 times per second, therefore, judge that whether the brightness of described ambient light mate to contain with the display parameter of described electronic display and judge whether described screen scanning frequency is greater than 60 times per second, judge that whether the brightness of ambient light be 3 times of screen intensity, if the brightness that screen scanning frequency is less than 60 times and/or ambient light per second is not 3 times of screen intensity, then the brightness of representative ring environmental light and the brightness of electronic display are unmatched, need to carry out the comfort level adjusting to ensure eyes of user, then system generates the information of relevant light adjustment.
It should be noted that, the adjustment of light contains the adjustment of ambient light and the adjustment of electronic display screen displays parameter, the adjustment of ambient light can generate relevant ambient light by intelligent glasses and adjusts information and send to terminal, and on the display screen of terminal, display prompting user go the operation carrying out being correlated with, operation of such as turn on light, to draw the curtain together and so on etc.; The light display parameter that the adjustment of the relevant display parameter of electronic display generates relevant electronic display by intelligent glasses adjust information and send to terminal, and on the display screen of terminal, display prompting user go the operation carrying out being correlated with, intelligent glasses also can be had to send relevant adjustment instruction and to be adjusted by terminal to terminal.
