The control command of the natural language form that for example receives is:
The flashlamp pass.
Then instruct in the splitting step, at first in retrieval " the flashlamp pass " the words the keyword that exists in how many databases is arranged.
Promptly based on database, look into the keyword in the control command of natural language form, carry out one time relatively complete.Can find that from aforesaid database list " the flashlamp pass " comprises " flashlamp " and " pass " two keywords.
Then can be earlier according to keyword " flashlamp ", find its corresponding basic controlling order element " LT ", and " LT " pairing action parameter item, because the action parameter item is associated with the property parameters item, then further utilize database index, in " LT " corresponding property parameters item (comprising open and close), search the basic controlling order element " OF " of keyword " pass "
3. instruction translation promptly according to keyword, obtains corresponding basic controlling order element, and according to the discernible basic controlling order format of predefined camera, described basic controlling order element permutation and combination is become the basic controlling instruction;
Each keyword correspondence the basic controlling order element of an actual camera control in the database.With the order element of comprehensive all keyword correspondences,, obtain the basic controlling instruction in this step through classification and ordination.
Continuation is an example with aforesaid " the flashlamp pass ":
With " LT " and " OFF " respectively as the described basic controlling order format of being filled into of data correspondence: in target+action+attribute+specification.
Find to also have in this basic controlling order format target component item and specifications parameter Xiang Wei to be filled data then, judge further then whether they all have the data of acquiescence respectively, as previously mentioned, the default data that system can set in advance the target component item is B3, promptly represent camera B3, therefore B3 is filled in the target component item.Because the user does not provide the instruction of closing camera after the delay how long, so system can module specifications parameter item be 00.
Promptly obtain the basic controlling instruction and be B3+LT+OF+00.
4. instruction is carried out, and is about to the basic controlling instruction and acts on camera;
In the present embodiment, this step can adopt existing technical scheme to realize, promptly system is by the driver of camera, basic controlling is instructed after the B3+LT+OF+00 format, and call function CloseLamp (0,0), the control camera is closed flashlamp.
Again for example, the control command of the natural language form of input is:
Bright
From aforementioned database table list, can find the corresponding LT of this " bright " and two action parameter items of EP (exposure), therefore can not determine that flashlamp is bright or the picture shading value is bright?
The situation that a plurality of basic controlling order elements belong to a parameter item appears obtaining this moment, and belong to the corresponding a plurality of basic controlling order elements of a keyword, therefore can be used to generate the basic controlling instruction by optional immediately one of them the basic controlling order element of system.System can choose one wantonly, is because the result can be the same, and picture is brightened.
Certainly, also can according to circumstances judge by system,
Can generate basic controlling instruction B3+LT+ON+00 earlier such as system
Found that flashlamp is bright!
Then system changes B3+EP+UP+01 (time shutter increases a chronomere) into from being about to basic controlling instruction
Again for example, the control command of described natural language form is:
Left-hand rotation 30 degree, track human faces
Then resolve and obtain: find 2 keyword " left side " and " people's faces " that belong in the property parameters item, corresponding basic controlling order element is " LF " and " FC ".Belong to and search the situation that a plurality of basic controlling order elements that obtain belong to same parameter item, and the corresponding basic controlling order element of keyword.Then the sequencing that occurs in the control command of described natural language form according to keyword generates many basic controlling instructions accordingly.Promptly generate two groups of format orders,
Preliminary translation: B3+MV+LF+30
B3+MV+SC+00
Carry out successively sequentially.
5. intelligent replying is promptly realized the man-machine conversation between system and the user;
Intelligent replying function among the present invention generally can be specifically embodied as following several application scenarios.
(1) the general answer:
The answer language of described natural language form is placed in the database in advance, is associated with the duty/execution result of described local camera.
In the general Recovery Process, system obtains the duty and/or the execution result of described controlled object (being camera in the present embodiment), then according to the duty and/or the execution result of described controlled object, obtain the answer language of corresponding natural language form based on described database lookup, and show this answer language
Replying language also can have many, when program need be replied, can find corresponding answer language according to duty/execution result, then one of picked at random therefrom.
Such as:
User command: 5 degree turn left
Local camera is replied: be finished!
(2) ambiguity is replied:
If each parameter item in the described basic controlling order format exists not to fill as data with the corresponding basic controlling order element of keyword, and the data that also do not have the acquiescence that can be used to fill, and work as according to the basic controlling order element of filling in its previous parameter item, utilize described index, in this parameter item that is not filled that finds from described database there being when a plurality of corresponding basic controlling order element, has just caused ambiguity or uncertainty.Need to start the intelligent replying function this moment, described instruction interpretation unit all sends to described intelligent replying unit with all basic controlling order elements in this parameter item that is not filled, described intelligent replying unit becomes the answer language of the natural language form of prompting user affirmation with its reverse translation, and exports this answer to the user and speak.
As:
The control command that the user sends the natural language form is:
Change!
Instruction interpretation obtains: " MV " in " commentaries on classics " respective action parameter item, but with " MV " associated attributes parameter item in have multiple attribute instructions such as LF, RT, UP, DN (about about).
Does therefore the intelligent replying unit forms the answer language: turning left, turn right, go up commentaries on classics still change down?
The user confirms: a left side!
Instruction interpretation unit translation a: left side=LF, and explain: B3+MV+LF+05 (B3 is the camera numbering of current acquiescence, the 05th, and the rotation step-length of current acquiescence, 5 steps.)
(3) error return:
Described intelligent replying unit can be according to the basic controlling instruction of described instruction interpretation unit output, and from the work at present state of the local camera that described command executing unit obtained, judge whether current basic controlling instruction can be carried out, and when instruction can't be carried out, reply miscue.
As:
User command: 5 degree turn left
Camera is replied: turn left to the end, can't turn left.
(4) reply answer:
Described intelligent replying unit can ask a question at the user, inquires about the work at present state of local camera, makes corresponding answer.
User command: position?
Camera is replied: on the left avertence.
Should be noted that, the said method of present embodiment, language expression for complexity, the explanation of instruction may be wrong, but the ambiguity answer by the intelligent replying process can reduce error probability greatly, and system can also be combined into the elementary instruction control element after the translation answer language of being made up of the keyword of correspondence by in the intelligent replying process, and send to user's affirmation, after obtaining affirmation, carry out the control corresponding instruction again.System also can increase the function of self study, automatically store some incoming frequencies than the pairing basic controlling instruction of the control command of higher natural language form, the keyword that perhaps automatically some is obtained the natural language form of user's affirmation adds in the database, so that later use also can be reduced to error probability the acceptable level thus.On the other hand, because, generally be to be confined within the function of particular range for the control of special object.So this has strengthened the understandability of this method to natural language.Such as: camera generally is tens functions such as rotation, image parameter adjustment, target tracking, and language performance is limited in the scope.And as control command, user's input language generally all can be very simple and direct.The discrimination that this has improved this method has strengthened the practicality of this method.
