Embodiment
Below in conjunction with accompanying drawing, structural principle of the present invention and operation principle are described in detail:
Refer to Fig. 1, it is the schematic diagram of supervisory control system.In supervisory control system, supervising device 1 need to carry out continual shooting to monitoring environment, and the vision signal crossfire (Streaming Media) that shooting is drawn is sent to server 3 by network 5.Or vision signal crossfire is stored in inside by supervising device 1.Below only taking a supervising device as example, but a supervisory control system may comprise multiple supervising devices, therefore this part can be analogized not describe in detail.
Refer to Fig. 2, it is the block diagram of supervising device.Supervising device 1 comprises: Video Recorder 15, infrared detector 13, timer 11.Wherein timer 11 is electrically connected on Video Recorder 15 and infrared detector 13.
Infrared detector 13 can be passive infrared detector (Passive Infrared Sensor, referred to as PIR).In response to the state variation of monitoring range, selectivity produces infrared ray triggering signal to infrared detector 13.For example, suppose that monitoring environment is a room, and the camera lens of supervising device 1 and infrared detector 13 are towards doorway, room.
In the time that door continues to close, infrared detector 13 can't produce infrared ray triggering signal.When door is opened in process, infrared detector 13 senses different infrared rays and distributes, thereby starts to produce infrared ray triggering signal.If enter user in room while going about, infrared ray triggering signal also continues to produce.If the user who enters in room maintains an anchor or withdrawn from a room a period of time, infrared ray triggering signal will stop producing.
As previously mentioned, infrared ray triggering signal can be used for representing the state variation in monitoring environment.During maintaining generation infrared ray triggering signal, represent that the state in monitoring environment still continues to change.According to conception of the present invention, during utilizing timer 11 accumulative total infrared detectors 13 to stop producing infrared ray triggering signal, and T between lay-up period will be defined as this period
idle.Video Recorder 15 is taken the vision signal crossfire corresponding with monitoring range.T between the lay-up period calculating according to timer 11 in addition,
idle, Video Recorder 15 will be adjusted the shooting quality of vision signal crossfire dynamically.
Suppose that Video Recorder 15 provides two kinds to take quality, first takes quality and second takes quality.Wherein the first shooting quality is better than the second shooting quality.First takes the difference of quality and the second shooting quality, can be the compression ratio while taking monitoring image, and/or frame rate (frame rate) etc.Certainly, the first difference of taking quality and the second shooting quality is not as limit.
When practical application, first takes quality can set for user's preference or purposes with the second shooting quality.For ease of explanation, below suppose that the first shooting quality is a default shooting quality, and the second shooting quality is an energy-conservation shooting quality.
Taking compression ratio as example, supervising device 1 can provide set-up function, allows user decide the default compression ratio of taking quality and energy-conservation shooting quality in its sole discretion.For example, user can be set as the default quality of taking, and will monitor image compression is 1/2nd, and energy-conservation shooting quality can be 1/8th by monitoring image compression.
Frame rate represents the quantity of the monitoring image in the unit interval.Therefore, while adopting default shooting quality, represent that Video Recorder 15 is within the unit interval, the quantity of taking the monitoring image drawing is more.While adopting energy-conservation shooting quality, represent that Video Recorder 15 is within the unit interval, take the negligible amounts of the monitoring image drawing.
Fig. 3 supposes that supervising device 1 is in the time of a start, the default shooting quality capture video signal crossfire first setting according to user.Afterwards, by the establishment in response to idle condition whether supervising device 1, selects whether to change the shooting quality of vision signal crossfire.
Refer to Fig. 3, the flow chart of its method for supervising.First, the shooting quality of vision signal crossfire is set as after (or being maintained) default shooting quality (step S11), starts to take the vision signal crossfire (step S13) corresponding with monitoring range.Then whether set up (step S15) according to the idle condition of infrared ray triggering signal judgement.If the judged result of step S15 for negating, maintains (or changing to) and takes quality capture video signal crossfire (step S11, step S13) to preset.
On the other hand, if the judged result of step S15 is for certainly, the shooting quality of vision signal crossfire is set as to (or being maintained) energy-conservation shooting quality (step S17).Thereafter, supervising device 1 is with energy-conservation shooting quality capture video signal crossfire (step S13).
Supervising device 1 can carry out the flow process of Fig. 3 repeatedly.Therefore, at supervising device 1, during with energy-conservation shooting quality capture video signal crossfire, supervising device 1 can be once again according to T between lay-up period
idlelength, whether the idle condition of judgement sets up (step S15).
If idle condition is maintained in immediately, represent that monitoring environment does not still have different shape (state does not change), therefore Video Recorder 15 can continue with energy-conservation shooting quality capture video signal crossfire (step S17, step S13).If idle condition while being false, represents that state variation appears in monitoring environment, therefore Video Recorder 15 can change to preset and takes quality capture video signal crossfire (step S11, step S13).
Certainly, the practice of quality, the execution mode of the other types of also can arranging in pairs or groups are taken in this kind of selectivity adjustment.For example, supervising device 1, in the time of start, adopts energy-conservation shooting quality capture video signal crossfire, if infrared detector 13 produces after infrared ray triggering signal, Video Recorder 15 just changes presetting shooting quality capture video signal crossfire into.
According to conception of the present invention, timer 11 can be in response to the generation situation of infrared ray triggering signal, produces the adjustment signal of coordination standard not to Video Recorder 15.In addition, Video Recorder 15, by accurate in response to the position of adjusting signal, dynamically change and takes quality.
For example, when infrared ray triggering signal stops after length, while generation once again, timer 11, except resetting between (reset) lay-up period, also synchronously produces the adjustment signal of high levels to Video Recorder 15.Video Recorder 15, after receiving the adjustment signal of high levels, will be taken quality capture video signal crossfire to preset.
Moreover if infrared ray triggering signal stops length, but idle condition is not while setting up yet, timer 11, except continuing between accumulative total lay-up period, also maintains the adjustment signal of output high levels to Video Recorder 15.During this period, Video Recorder 15 maintains to preset shooting quality capture video signal crossfire.
And for example, when infrared ray triggering signal stops length, and when idle condition is set up, timer 11 produces the adjustment signal of low level to Video Recorder 15.Video Recorder 15, will be with energy-conservation shooting quality capture video signal crossfire after receiving the adjustment signal of low level.
When practical application, the state of monitoring environment changes, and may betide in a flash, also may maintain length.Along with the length difference that state changes, during the actual generation infrared ray of infrared detector 13 triggering signal, length is also not quite similar.
Once infrared ray triggering signal starts to produce, timer 11 just suspends T between calculating lay-up period
idle(also can be made zero).And timer 11, after infrared ray triggering signal finishes, starts to calculate T between lay-up period
idle.In other words,, when longer during infrared ray triggering signal maintains generation, timer 11 stops calculating T between lay-up period
idleduring also longer.
How the 4th figure explanation calculates T between lay-up period according to infrared ray triggering signal
idle, and how further according to T between lay-up period
idlethe concept whether idle condition of judgement is set up.Need be careful, while being applied to supervising device 1, the generation time point of infrared ray triggering signal is not as limit.
Refer to the 4th figure, it is the sequential chart that adopts the embodiment of method for supervising.This graphic infrared ray triggering signal and shooting quality of being from top to bottom respectively.For ease of explanation, in the time taking quality for default shooting quality, represent with the net bottom of higher levels.In addition, this graphic X direction represents the time.Idle threshold Tth can be set by user (for example: 30 seconds, 5 minutes), or the reference settings of idle threshold is provided by the manufacturer of supervising device 1.
After supervising device 1 is by start time point T0 start, Video Recorder 15 is first taken quality capture video signal crossfire to preset.At the same time, timer 11 also starts to calculate T between lay-up period
idle.Suppose by (A during this time) during start time point T0 to the first time point T1 all without any infrared ray triggering signal generation, supervising device 1 during A still maintain to preset shooting quality capture video signal crossfire.
Thereafter, at the first time point T1, T between the lay-up period of timer 11 accumulative totals
idlereach idle threshold Tth.Therefore, supervising device 1 will judge idle condition establishment at the first time point T1.Related, supervising device 1, after the first time point T1, changes with energy-conservation shooting quality capture video signal crossfire.Now, timer 11 still maintains T between accumulative total lay-up period
idle.
Then suppose that an infrared ray triggering signal results from the second time point T2, and between the 3rd time point T3.The second time point T2 is that initial time point, the 3rd time point T3 of infrared ray triggering signal is the end time point of infrared ray triggering signal.
In the time of the second time point T2, infrared detector 13 senses monitoring range generation state variation, thereby produces infrared ray triggering signal.Therefore, supervising device 1 will be started by the second time point T2, take quality capture video signal crossfire to preset.As shown in Figure 4, by B during between the first time point T1 to the second time point T2, maintain the shooting quality of vision signal crossfire is set as to energy-conservation shooting quality.
Between the second time point T2 and the 3rd time point T3, infrared detector 13 all continues to produce infrared ray triggering signal.Accordingly, timer 11 can the second time point T2 and the 3rd time point T3 between, also stop calculating T between lay-up period
idle.Therefore, Video Recorder 15 during C all maintain to preset and take quality capture video signal crossfire.
Infrared ray triggering signal stops producing at the 3rd time point T3.After the 3rd time point T3, timer 11 is by T between lay-up period
idlereset.Afterwards, Video Recorder 15 temporarily maintains to preset shooting quality capture video signal crossfire.As seen from Figure 4, after the 3rd time point T3, Video Recorder 15 during D still use the default quality of taking.
After the 3rd time point T3, after during idle threshold Tth, be the 4th time point T4 in Fig. 4.Now idle condition is set up once again, and Video Recorder 15 changes once again with energy-conservation shooting quality capture video signal crossfire.
Refer to Fig. 5, the thin portion flow chart that the idle condition of its method for supervising judgement is set up.First the state that judges monitoring range whether change (step S151).If the judged result of step S151 is for affirming, infrared detector 13 will produce infrared ray triggering signal (step S152).Then, timer 11 is by T between replacement lay-up period
idle, and the idle condition of supervising device 1 judgement be false (step S158) (S154).
On the other hand, if the judged result of step S151 is to negate, timer 11 will add up T between lay-up period
idle(step S157).T between the lay-up period of timer 11 the further current accumulative total of judgement
idlewhether be more than or equal to idle threshold (step S153).If the judged result of step S153, for certainly, represents idle condition establishment (step S155).If the judged result of step S153 for negating, timer 11 is by the judgement condition be false (step S158) of leaving unused.
As seen from Figure 5, T between lay-up period
idlecalculating, can whether determine according to the generation of infrared ray triggering signal.For example: as described in step S157, in the time that infrared ray triggering signal does not slowly produce, timer 11 continues T between accumulative total lay-up period
idle.As described in step S154, after infrared ray triggering signal finishes, T between timer 11 replacement lay-up periods
idle.
Can learn according to above stated specification, supervising device 1 of the present invention, can be in response to T between lay-up period
idlelength, judgement should be taken quality capture video signal crossfire with which kind of.
T when between lay-up period
idletth while being more than or equal to idle threshold, represents that existing a period of time of monitoring environment occurs without special event.Now, preset take quality capture video signal crossfire if maintain, may only can obtain the unconverted monitoring image of milli, this kind do not had a monitoring image of special meaning, the added burden while causing taking on the contrary.Therefore, the shooting quality of vision signal crossfire is set as energy-conservation shooting quality by Video Recorder 15.On the other hand, when infrared ray triggering signal is producing, although or infrared ray triggering signal stopped producing T between lay-up period
idlewhile being less than idle threshold, represent that monitoring environment may have emergency situations.Now, the shooting quality that Video Recorder 15 is set vision signal crossfire is for presetting shooting quality.
Method for supervising provided by the invention, can, dynamically in response to the situation of monitoring environment, adjust the shooting quality of vision signal crossfire.Supervising device 1 can, really need to carefully watching monitoring when image, maintain good image quality, and the efficient reduction required storage area of immediately making video recording.In addition, the frequency range of Internet Transmission and system power dissipation also can improve in synchronization gain.
Certainly; the present invention also can have other various embodiments; in the situation that not deviating from spirit of the present invention and essence thereof; those of ordinary skill in the art are when making according to the present invention various corresponding changes and distortion, but these corresponding changes and distortion all should belong to the protection range of the appended claim of the present invention.
