The present invention provides a kind of one embodiment of the study exchange method of smart machine, as shown in Figure 1, comprising:

S1 smart machine, which obtains, puts question to area image.

Specifically, smart machine can be obtained by photographing module puts question to area image, the photographing module in the present invention can be with For camera, it is mountable on intelligent devices, smart machine includes intelligent desk lamp, intelligent pendent lamp, intelligent wall lamp etc., mountable Near desk, the image for enabling smart machine to get books on desk by installing photographing module on the body is believed Breath.

Student do not know or the topic that will not do in study if having to encounter, can be with finger to no topic, then It says that " how this problem does " or " how the first topic is done " etc. are similar and puts question to language.Smart machine can acquire the voice letter of user in real time Breath asks voice messaging conversion to text information, then judges whether there is and put question to keyword (such as " how doing ", " how doing ", " such as What is said " etc.), when smart machine identifies in the voice messaging of user containing keyword is putd question to, camera can be analyzed and collected Image, the direction of profile and finger sold by image recognition technology identification, and be directed toward on region and find out in finger User wants the region where the topic of inquiry, using the image in this region as enquirement area image.

Smart machine described in S2 parses subject of question from the enquirement area image of acquisition, then mentions described in acquisition It asks content corresponding answer content, and projection information is generated according to the answer content.

Specifically, can be integrated in smart machine picture processing chip (such as FH8510 picture processing chip or FMS6502 picture processing chip), the subject of question putd question in area image can be parsed to puing question to area image to identify, Such as parse enquirement area image, obtain subject of question: " the 4th topic, Xiao Ming have bought 5 jin of apples, 3 yuan of apple per jin, little Ming Yi Need that how much is paid altogether? ".

Smart machine can be found out in the corresponding answer of subject of question according to subject of question in the knowledge base stored in advance Hold (including topic parsing, detailed answer step etc.).

Again alternatively, subject of question can be sent to clothes after parsing subject of question in enquirement area image by smart machine Business device.Knowledge base can be stored in advance in server end, and server can search corresponding solution according to subject of question in knowledge base Content is answered, and answer content is returned into smart machine.The phase of storage knowledge base is not needed in the technical program, on smart machine Data are closed, the requirement to smart machine reservoir are reduced, to reduce the manufacturing cost of smart machine.

Smart machine described in S3 obtains the luminous intensity of the bias light of view field, and adjustment generates when projecting the projection information Projection light and bias light between light intensity difference, and the projection information is thrown according to the luminous intensity of projection light described after adjustment It is incident upon view field.

Projection module, such as Miniature projector can be equipped on smart machine.Smart machine can be according to preset projection template (including: answer column, parsing column, knowledge point column) will answer corresponding content in content and be added to each of projection template In a column, to generate projection information.User can preset projection module projection pattern (including LED projection, light throw Penetrate, 3D holography projection, AR projection), projection information is projected to default view field.

In practical applications, if background light is stronger, and throw light is weaker, and will lead to the projection cast out can not see It sees；If because throw light is stronger, and background light is weaker, then it is too dazzling to will lead to the projection cast out, produces time viewing Projection can injure the eyes of student.

Therefore, a photosensitive sensors be will be installed on the smart machine in the present embodiment, to the bias light of view field Luminous intensity is detected, and then be will test result and is fed back to smart machine, smart machine is in the luminous intensity by bias light, in time Adjustment projects the light intensity difference between the projection light and bias light generated when the projection information, reaches the projection projected Good drop shadow effect.

For example, the luminous intensity of projection light can be then properly increased when the light strength ratio of the bias light of view field is stronger, Make student that can also check project content without barrier under the premise of not closing lighting device.When the light of the bias light of view field It when intensity is weaker, then can be projected according to the luminous intensity of normal projection light, make projection will not be too dazzling, protection student's view Power.

Preferably, the present embodiment is in projection further include:

The smart machine obtains the affiliated subject type of the subject of question according to the subject of question, analysis.

Smart machine subject type according to belonging to the subject of question, selects corresponding projection pattern by the solution It answers content and is projected to the default view field.

Specifically, intelligent terminal can carry out semantic understanding to subject of question, subject belonging to the subject of question is analyzed Type；The matching of subject can also be carried out by the subject keyword in subject of question, for example, if when occurring chemical formula in topic, It can determine whether out that subject of question is chemical classes, if occur a large amount of English in topic, can determine whether out that subject of question is English classification； Again alternatively, the page where the page number or subject of question of page where the question number of subject of question perhaps subject of question can also be passed through Position, match corresponding books, then the subject category according to this books, determine the subject class of subject of question Not.

The present embodiment, can be automatic in projection in order to make the mode of projection be more in line with the characteristic of the affiliated subject of subject of question Corresponding projection pattern is selected to be projected.For example, when the subject belonging to the subject of question is English, since English is all text Type answer, thus with the mode of plane projection carry out projection can reach better viewing effect；And work as belonging to subject of question When subject is geometry, since geometric figure is solid figure, if being projected in a manner of plane projection, student can be understood Answer causes certain difficulty, and the purpose for providing and solving a problem for student is not achieved；And it is projected in a manner of tripleplane, Xue Shengke To understand from different perspectives the three-dimensional geometric shapes projected, the problem of encountering is made to be more easier to answer.For another example When the affiliated subject of subject of question is geographical, studied about mountainous region, ocean, weather etc. due to being all much geographically, if with Plane projection mode projects answer content, possibly student can not be allowed to have intuitive experience.As student understand karst landform, When the landform such as "Danxia" landform, coastal landform, glacial landforms, if projecting relevant picture in a manner of plane projection, student may The characteristic of all kinds of topography and geomorphologies can not be understood completely, thus be not easy to distinguish different terrain landforms, and in a manner of tripleplane Answer content is projected, student can from different angles observe various landforms, it is easier to distinguish different terrain landforms Feature.

When projection, a desktop area can be detected from the image information that photographing module acquires by image recognition technology, Using this region as default view field.In order to generate better drop shadow effect in projection, it mating can also increase by one piece of throwing Projection plate can be placed on desk, camera can automatically identify throwing by image recognition technology by shadow plate, student in study The position of plate is penetrated, while adjusting the projecting direction of projection module, image is projected on projection plate.

This programme combines necessity --- lamps and lanterns used when student's study, and acquisition problem, solution are integrated on lamps and lanterns The functions such as question and answer topic, display answer content can provide help in time when student's study is met difficulty for student.This programme In, after smart machine gets answer content, answer content is cast out in a manner of projection, does not need externally connected with display screen Curtain adds display screen on lamps and lanterns, increases the popularity of application.Simultaneously can only lamps and lanterns can be directed to different subject types, Selection more preferably projection pattern projects.

In addition, the present embodiment considers student when needing to project the stereo-pictures such as geometric figure or kinds of experiments equipment Can often there are mapping, even auxiliary line, the operation such as add other figures when doing geometry topic, when doing experimental problem, it is often necessary to will A variety of equipment are combined, while student is more complete, comprehensively checks the geometric figure being projected out in order to make, energy when testing Enough there is more intuitive experience, this programme increases edit operation when being projected in a manner of tripleplane, and user can be It is edited accordingly on the 3-D image projected, learning Content is best understood from this.

For example, when the time for touching arbitrary point on the 3-D image reaching the first preset time, or work as described in touching On 3-D image at any at least 3, it is image drag operation that the smart machine, which parses the edit operation, and according to The image drag operation at family drags 3-D image.

When the time for touching arbitrary point on the 3-D image reaching the second preset time, the smart machine parses institute Edit operation is stated as image rotation operation, and 3-D image is rotated according to the operation of the image rotation of user.

When any two points on the touching 3-D image, and when two touch points distance diminutions, the smart machine solution The edit operation is analysed as image down operation；When touching any two points on the 3-D image, and two touch points distances When becoming larger, the smart machine parses the edit operation as image amplifying operation.

Reach the 4th preset time when the time for touching any point on the 3-D image, and touch points moving distance is big When pre-determined distance, it is to make graphic operation that the smart machine, which parses the edit operation,.

When user clutches a certain figure in the 3-D image, the smart machine parses the editor behaviour It is operated as image-erasing；And add when the speech detection module 6 of smart machine listens in the voice messaging of user comprising figure When adding information, then the corresponding figure of the figure addition information is added in 3-D image, such as user says " addition cylindrical body ", Smart machine can analyze by semantic understanding when listening to the words and need to add " cylindrical body " this figure.

Optionally, in the present embodiment, the smart machine analyzes the subject of question, obtains belonging to the subject of question Subject, the specific chapters and sections of the affiliated subject of subject of question and the concrete knowledge point of the affiliated chapters and sections of the subject of question, and remember It records history of forming and puts question to record；The smart machine puts question to record according to the history in preset period of time, generates different subjects It practises in the learning evaluation report of different chapters and sections in appraisal report and/or each subject and/or each chapters and sections of each subject not Learning evaluation with knowledge point is reported.

For user after inquiry problem, smart machine can all record relevant subject of question, and carry out to subject of question Analysis, obtains subject belonging to the subject of question, in the specific chapters and sections of the affiliated subject of subject of question and the enquirement The concrete knowledge point of chapters and sections belonging to holding.When user wants to know about the study situation of nearest a period of time, smart machine can root Record is putd question to according to the history of this period, corresponding learning evaluation report is generated, user is helped to understand current study condition.Example When needing the learning evaluation of this subject of this term mathematics to report such as user, then it can be putd question to and be recorded according to history, smart machine meeting The historical record that this term is asked questions extracts, and is sorted out according to the affiliated chapters and sections of each problem, and affiliated knowledge point is returned Class, evaluate user in Mathematics Discipline each chapters and sections, each knowledge point study situation.

The present invention also provides a kind of one embodiment of the study exchange method of smart machine, as shown in Figure 2, comprising:
