More than finished the basis transformation of NVD and NLC interlock, these basic transformations can realize with reference to various known designs/protocol specifications, not very strict restriction, and it also is feasible adopting privately owned design.After transformed on the basis of finishing interlock, NVD and NLC just can begin actual interlock handling process.Please refer to Fig. 3, the invention provides the intelligent linkage device on a kind of NVD of being applied to, comprise illumination detection module, intelligent control module, professional sensing module and Service Processing Module.Wherein the Service Processing Module image that is mainly used in that NVD is collected carries out miscellaneous service and handles, such as coding and message encapsulation etc.In a typical execution mode, this intelligent linkage device and NLC carry out the business interlock, carry out following steps:
Step 101, illumination detection module regularly detect lamp intensity and whether reach predetermined threshold value, go to enable if then enable described intelligent control module, if lamp intensity does not reach threshold value, then enable described intelligent control module, change step 102 and handle;
Step 102, intelligent control module issues the initial service parameter configuration to Service Processing Module;
Step 103, when detecting the upgrading service event, professional sensing module notifies described intelligent control module, the service parameter that intelligent control module is revised Service Processing Module according to the upgrading service event notice is configured to provide the picture quality of Service Processing Module output, and sends increase light source unlatching request to NLC;
Step 104 when NLC receives from the increase artificial light source request of NVD, is opened into the artificial light source of small part;
Step 105, when detecting professional degradation event again after the upgrading service event, professional sensing module notifies described intelligent control module, intelligent control module is configured to reduce the picture quality that Service Processing Module is exported according to the corresponding service parameter of revising Service Processing Module of business degradation event notice, and transmission reduces the request of artificial light source to NLC;
Step 106, NLC closes to the artificial light source of small part when receiving from the minimizing artificial light source request of NVD.
The present invention with business change with artificial light source enable and Business Processing is associated.When monitoring business generation change of rank, start/close artificial light source.For the business of video camera, under the inferior grade business, its processing requirements to video camera is lower, and is also lower to the illumination requirement of camera supervised scene.Such as for a long period maintenance tableaux outgoing traffic grade, it is very little for user's meaning that adopt too high code rate to obtain high-quality image this moment, even whole image is also can accepting of black and white for the user, because user's obtainable useful information of institute from a still frame is fewer.
Same reason, under the such grade of service of tableaux, video camera does not need extraordinary illumination condition yet, and the picture exposure is also too big meaning not concerning the user fully, and the picture under-exposure also can be accepted substantially for the user.Based on such application prerequisite, the present invention comes the intensity of illumination of corresponding change Business Processing and monitoring scene by the variation of the grade of service, target is under the circumstances that satisfies user's primary demand, reduce the power consumption of artificial light source as much as possible, can also reduce the video camera power consumption simultaneously, and even reduce the pressure to the network bandwidth, for example, code rate when descending required transmission bandwidth also can descend naturally.
In the preferred implementation of the present invention, the grade of service can be the definition that the developer forms on stream, and the modification of service parameter configuration can be not limited to the following example that provides based on developer's definition too.The present invention provides one to realize that difficulty example moderate and that closing to reality is used illustrates the Technical Architecture that topic is stated more than the present invention at this, the developer can extend design on the basis of this example, both can simplify also and can carry out more senior and intelligent design.In the present embodiment, professional sensing module can comprise mixes line detection sub-module and motion detection submodule, and being used for two kinds of perception typically influences the events of the grade of service.
Step 201, when initial condition, the intelligent control module of NVD can call NLC and close near all artificial light sources of NVD; Notice illumination detection module detects and carries out the lamp intensity detection;
Step 202, the illumination detection module judges according to the output of the light-sensitive device of video camera whether current lamp intensity reaches threshold value, if reach then intelligent control module is gone to enable, if do not reach, then enables described intelligent control module;
Now the current images drainage pattern is become white-black pattern after step 203, intelligent control module enable, code rate (calling " code check " in the following text) is reduced to half of standard code check;
When natural daylight satisfied the business need of video camera, under the situation such as the daylight abundance, video camera is auxiliary without any need for artificial light source generally, namely do not need the NVD NLC that goes to link to close or open artificial light source usually.When natural daylight can't satisfy the business need of video camera, need this moment intelligent control module to go to coordinate relation between artificial light source and the business.In initial, intelligent control module can be revised the service parameter configuration of Service Processing Module, makes it adopt a lower initial service configuration, reduces half as the said code check of present embodiment, and image acquisition modality is white-black pattern.That is to say that acquiescence adopts a low-power consumption, the Business Processing mechanism of low image quality earlier.If the follow-up business change of rank adjust again.
Step 204, enter into and mix line when inner from mixing the line periphery when professional sensing module detects mobile object, notice intelligent control module, intelligent control module call NLC illumination control service request NLC immediately near light source are opened half, transfer the code check of Service Processing Module to the standard code check;
Please refer to Fig. 4, in monitoring business, the user has the needs of mixing line detection and motion detection usually, will mix the foundation that line detects and motion detection changes as the grade of service in the present embodiment.Detect and can determine whether that one or more mobile objects enter into and mix line inside by mixing line, can determine upgrading service this moment in case have object to enter to mix line inside, the monitored picture of this moment has Useful Information concerning the user in a large number probably.The picture quality that should preferentially improve picture this moment is avoided the loss of useful information.Improving picture quality can set about from two aspects, starts with from the parameter of Service Processing Module on the one hand, such as improving code check or image model being adjusted into colour etc.; Can start with from illumination on the other hand, come to be the video camera light filling by opening artificial light source, avoid the video camera under-exposure.In preferred mode, when intelligent control module passed through NLC opener worker light source, corresponding notice illumination detection module quit work, and is equivalent to the illumination detection module and goes to enable.
Step 205 when if professional sensing module detects the motion detection zone again and has mobile object after the step 204, can determine that business upgrades corresponding notice intelligent control module again this moment; Intelligent control module then calls NLC illumination control service request NLC near all artificial light sources is opened, and transfers Service Processing Module to color mode;
Step 206, if professional sensing module detects mobile object again and goes to and mix line when peripheral from mixing line inside after the step 204, then notify intelligent control module, and intelligent control module can call after a period of time such as the section of grade (as 10 seconds) NLC illumination control service with near all opener worker's light source close, and with the code check of Business Processing processing module transfer to normal code check half, be equivalent to get back to initial service parameter configuration.In preferred mode, when intelligent control module was closed all artificial light sources by NLC, corresponding notice illumination detection module worked on, and is equivalent to the illumination detection module and enables.
Step 207, after step 205, if professional sensing module detects mobile object and goes to and mix the line periphery from mixing line inside, when there is mobile object in the motion detection zone simultaneously, wait for 10 seconds and detect the motion detection zone again whether have mobile object, if there is not the professional degradation event of notice intelligent control module, intelligent control module then wants to ask NLC that near light source is closed half, transfer the image acquisition modality of Service Processing Module to white-black pattern, keep code check and remain unchanged.
Step 208, after step 207, line is mixed in the lasting detection of professional sensing module touchless, if continue touchless in 10 seconds, then notify intelligent control module professional degradation event, and intelligent control module respective request NLC closes near all light sources of having opened, and code check is reduced to half of configuration code check, makes the service parameter configuration of Service Processing Module get back to the initial service parameter configuration.
In the above-described embodiment, the intelligent control module of NVD still can ask NLC to open or close light source based on the message in the ONVIF agreement.It is as shown in table 3 that NVD request NLC opens the message examples of light source, and corresponding message definition principle of closing light source is identical.
Table 3
Step 201 is mixed line by detection and is determined whether to take place upgrading service or professional degradation event with detection appointed area (being the motion detection zone) to step 208 execution mode.Detection and the detection of motion of mixing line are the most typical two kinds of professional perceptive modes, and in fact, Intelligent Measurement such as the detection of people's face, vehicle detection even Smoke Detection equally can be as professional perceptive mode in the application-specific scene.Along with the evolution of monitoring technique, have how better professional perceptive mode and occur, one of ordinary skill in the art will appreciate that these professional perceptive modes can be dissolved into the present invention fully.
The above only is preferred embodiment of the present invention, and is in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of making, is equal to replacement, improvement etc., all should be included within the scope of protection of the invention.
