Abstract
The invention provides a method for controlling a cradle head based on a voice recognition technology. By using the method, sentences of speakers are converted into a command for controlling the cradle head aiming at an application scene of a video monitoring system and directly operating and controlling the cradle head through the recognized returned instruction. The method for controlling the cradle head is convenient, easy to use, intelligentized and reliable.
Description
Technical field
The invention belongs to field of video monitoring and the artificial intelligent field of computing machine in the security protection industry, particularly based on the method for the cradle head control of speech recognition technology, and should invention in the application of video monitoring system.
Technical background
In the video monitoring system of security protection industry, cradle head control is must an obligato part, and cradle head control is to be used for the turning to of front-end camera, presetting bit, to cruise and module that track etc. is controlled.For client operation, traditional cradle head control have supervisory keyboard directly control with mouse to the simulation cradle head control platform software control, and the control technology of The Cloud Terrace being controlled by wireless network, these modes can both be finished The Cloud Terrace rotation, presetting bit control, The Cloud Terrace operation such as cruise.
But all there is the problem of two aspects in the method for these cradle head control, and being on the one hand all needs staff to interfere, and requires the operator to be familiar with controlling business, could normally control The Cloud Terrace; Be on the other hand these methods when being applied to a plurality of cradle head control, in a rush situation will appear.Therefore introducing artificial intelligence carries out cradle head control and becomes a current solution, this method need not be interfered by staff, saying plain statement by a microphone can control The Cloud Terrace, enriched the operation of video monitoring, reduced the difficulty that the user uses, also reduced cost of labor, improve user satisfaction, has good man-machine interaction, and this cradle head control also is applicable to obstacle personage's use, really accomplish convenience, practical, easy-to-use, have wide application scenarios at safety-security area and other fields.
Summary of the invention
The objective of the invention is at video monitoring system, utilize speech recognition technology to finish the sequence of operations of cradle head control, have very high accuracy, ease for use and favorable user experience.
In order to realize goal of the invention, the technical scheme of employing is as follows:
In system, as shown in Figure 1, utilize sound identification module that speaker's voice are gathered, carry out voice recognition processing in real time and return recognition result.Need a Control Server to receive to the recognition result that returns, Control Server is connecting speech recognition server (as shown in Figure 2) and two modules of DVR (can directly control the equipment of The Cloud Terrace).Gordian technique in the middle of this is how the control command of speaker's speech conversion for the operation The Cloud Terrace.Here we introduce the module of a syntax analyzer, at first do the key word of the voice of needs collection and corresponding the recognition result that returns corresponding one by one, when for example recognizing the voice command of " left ", be converted to the content that machine can receive through syntax analyzer, for example return recognition result " TurnLeft ", after Control Server receives the voice identification result of " TurnLeft " that speech recognition server returns, know that promptly the voice command that the speaker sends is the meaning that the control The Cloud Terrace turns left, then the control of equipment being turned left by the control SDK that calls The Cloud Terrace equipment and provide has so promptly been finished the voice control The Cloud Terrace of an assigned operation object and has been operated.In addition, in actual scene, speaker's voice be not only simple turn left, right-handed voice signal, but have the statement of qualifier, for example " I want turn left ", " how could controlling left-hands rotation ", " I need left-hand rotation " or the like, therefore we have increased filtration setting in syntax analyzer, when sound identification module receives in the grammer configuration management already present prefix or suffix qualifier, then automatic fitration returns to the recognition result that remains " TurnLeft " of Control Server.
The method of this cradle head control utilizes speech recognition technology that voice signal is converted to the operational order of cradle head control neatly, but also the statement of speaking of many qualifiers is filtered, and calls corresponding control command, and voice control maloperation is almost nil.

Embodiment
The present invention is described further below in conjunction with accompanying drawing.
The speech recognition technology that the present invention is based on is a kind of sound identification module that has nothing to do with the speaker, can finish the speech identifying function under the different application environment, possesses outstanding discrimination and intelligent.It is the voice that extract the speaker by end-point detection, discerns and handles and return recognition result.End-point detection is that the audio stream of input is analyzed, and determines the processing procedure of the initial sum termination that the user speaks.Loquitur in case detect the user, voice begin to flow to recognition engine, finish in a minute up to detecting the user.This mode makes recognition engine promptly begin to discern processing when the user speaks.In addition, the method that this speech recognition technology finally can feed back to Control Server and The Cloud Terrace is controlled, with the grammer configurator is inseparable, the grammer configuration is important in a system module, sound identification module is judged user's content of speaking in the grammer scope that sets in advance, export the semanteme of this grammer correspondence, and return to Control Server with XML result's form, Control Server is correspondingly to remove calling interface (as shown in Figure 4) according to the SDk that The Cloud Terrace equipment provides, and the identification return results in the configuration of the cradle head control interface table of Control Server and grammer is related one by one.
For shown in Figure 3 be grammer allocation list in this scene of cradle head control, on move out=" and make progress " } expression when by speech recognition behind key word " on move ", the result of output is " making progress ", this result turns back to Control Server with the form of XML, resolves and calls the control corresponding operation after this operates.Be used for the allocation list the inside of cradle head control at this, mate real cradle head control operation by the key word of enumerating all operations and the form of discerning back output.I want “ $pre=to look for " if be that the statement prelude that the expression speech recognition is returned has the key word of enumerating here, then automatic fitration is equivalent to remove prefix; “ $las=is what if " if be that the statement end that the expression speech recognition is returned has the key word of enumerating here, filter equally, be equivalent to remove suffix.So, the common statement that the speaker expresses, for example " I think the control left-hand rotation " can both be converted to the control command that machine can be discerned, as long as all cradle head control orders are all configured grammer.
