Below by way of specific instantiation, embodiments of the present invention are described, those skilled in the art the content disclosed by this instructions can understand other advantages of the present invention and effect easily.The present invention can also be implemented or be applied by embodiments different in addition, and the every details in this instructions also can based on different viewpoints and application, carries out various modification or change not deviating under spirit of the present invention.It should be noted that, when not conflicting, the feature in following examples and embodiment can combine mutually.
It should be noted that, the diagram provided in following examples only illustrates basic conception of the present invention in a schematic way, then only the assembly relevant with the present invention is shown in graphic but not component count, shape and size when implementing according to reality is drawn, it is actual when implementing, and the kenel of each assembly, quantity and ratio can be a kind of change arbitrarily, and its assembly layout kenel also may be more complicated.
In order to enable those skilled in the art understand technical scheme of the present invention better, below to some technology related in scheme for giving specific explanations explanation.
The first, focus, refers to and treats whether work attendance person's eye is absorbed on teaching scene or screen, generally can utilize and ask the ratio of open eyes T.T. and education activities T.T. to obtain.
The second, eyes-open state, namely refers to by processing image, to judge that whether eyes are wherein for opening state.In like manner, corresponding thereto also have closed-eye state, it is also by processing image, to judge that whether eyes are wherein for closing state.
Particularly, see Fig. 1, show a kind of focus attendance checking system of the present invention schematic diagram in one embodiment, as shown in the figure, described focus attendance checking system comprises: photographing module 10, for obtaining the face image treating work attendance person; First sampling mould 30 pieces, treats the face image of work attendance person by the first predeterminated frequency collection; Second sampling module 20, treats the face image of work attendance person by the second predeterminated frequency collection; Picture recognition module 40, for identifying that the eye profile in described face image is closed-eye state or eyes-open state, and set very first time timing node when first time detects the face image of closed-eye state, and when first time detects the face image of eyes-open state after described very first time timing node, set the second time timing node; Work attendance degree analysis module 50, according to described very first time timing node and the second time timing node, calculates closed-eye time value and the focus for the treatment of work attendance person; Form generation module 60, according to described closed-eye time value focus, generates focus Attendance Sheet and is exported.
Can be well understood to by such scheme and treat the eye opening of work attendance person or the state of eye closing, thus judge its focus situation in education activities, overcome the problem that cannot judge student's focus in existing network education activities easily with this.
Particularly, the first predeterminated frequency in such scheme should be less than the second predeterminated frequency, such as, the first predeterminated frequency be 1 minute once, and the second predeterminated frequency is 1 minute ten times or five times, such situation can avoiding occurring failing to judge or judging by accident.Such as, when the first predeterminated frequency and the second predeterminated frequency are all 1 minute one time, when until work attendance person's collected eye closing, it just maintains 30 seconds, and just in time closed one's eyes in the 60th second, now just in time be detected again, so treat that work attendance person will be considered to close one's eyes 60 seconds, and actual conditions be really not so.If therefore raising the second predeterminated frequency is also detected according to this, so will detect in the 30th second in 30 seconds and treat that work attendance person has opened eyes, thus avoid the situation of erroneous judgement.
Also the regular hour is needed, if the too high efficiency that also will influence the course of the frequency carrying out gathering, so usually the second predeterminated frequency to be set to 5 times to about 10 times of first and radio frequency owing to carrying out processing and identification to image.
In addition, be with being to be understood that, in above-mentioned focus attendance checking system, face image is identified, judge that eyes are in opening state or closed-eye state, be make use of existing image recognition technology, this can realize the identification of above-mentioned eye state to those skilled in the art without the need to paying creative work, its application just this image recognition technology and other creative technology combined, therefore repeat no more here.
Particularly, the method for eyes-open state and closed-eye state that judges is: the height value judging eye contour in image, if be greater than default eye contour height value, is eyes-open state; If be less than or equal to default eye contour height value, it is closed-eye state.
Those skilled in the art will be allowed below by way of example clearly to understand technical scheme of the present invention, particularly:
In Learning Activity, such as Promoting Network Teaching Research, Web-based Self-regulated Learning, in the active procedures such as Online Cooperative Learning, when education activities start, if the movable start time is A0, and gather in specific time interval once treat work attendance person face image (as collection per minute once, i.e. the first predeterminated frequency), the face image collected and the face image with eyes-open state when registering are contrasted, monitor its eye profile, if treat there is eyes closed phenomenon in work attendance person, record current point in time is A1, and automatically improve picture-taken frequency (as collection per minute once changed into every 5s collection once, namely the second pre-predeterminated frequency is adopted to gather), when capture open until work attendance person's eye time, recording current point in time is A2, calculating treats that work attendance person's eye closure time is T1=A2-A1, if T1 is less than or equal to a certain limit value (as 15s), then judge that this is as rationally closed, if T1 is greater than this limit value, then judge that this is as non-rationally closed, counted eye closure time, now according to the T.T. T=(A2-A0) that current active is carried out, calculate now that this treats that the eye focus of work attendance person is H1=1-T1/T.When again or repeatedly there is eye closing phenomenon until work attendance person, calculate according to above-mentioned focus attendance checking system and treat work attendance person's eye time T1 ', then now, this treats that work attendance person's head departs from the time and adds up to T2=T1+T1 ', the T.T. T ' that current active is carried out, calculates now that this treats the eye focus H1=1-T2/T ' of work attendance person.By that analogy, visible eye focus carries out real-time change along with activity, is in the end exported with the form of focus Attendance Sheet again.
In sum, the present invention identifies by treating work attendance person's eye state, thus judge its focus for teaching screen, effectively can treat work attendance person and exercise supervision and examine, avoid in existing network education activities the blind area of carry out imparting knowledge to students work attendance or examination.So the present invention effectively overcomes various shortcoming of the prior art and tool high industrial utilization.
Above-described embodiment is illustrative principle of the present invention and effect thereof only, but not for limiting the present invention.Any person skilled in the art scholar all without prejudice under spirit of the present invention and category, can modify above-described embodiment or changes.Therefore, such as have in art usually know the knowledgeable do not depart from complete under disclosed spirit and technological thought all equivalence modify or change, must be contained by claim of the present invention.
