Embodiment
The technical problem solved for making the present invention, the technical scheme of employing and the technique effect that reaches are clearly, be described in further detail below in conjunction with the technical scheme of accompanying drawing to the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those skilled in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Please refer to Fig. 1, it is the block diagram of first embodiment of a kind of automatic start-stop intelligent control method based on bimodulus camera that the embodiment of the present invention provides.The intelligent monitor system of the present embodiment is mainly used in the safety detection in school, building, market, factory, military place, provides general protection.
As shown in Figure 1, this automatic start-stop intelligent control method, comprising:
Step S110: infrared camera picked-up infrared monitoring picture in bimodulus camera.
Bimodulus camera refers to existing infrared camera in a picture pick-up device, has video frequency pick-up head again, can take with two kinds of different patterns.
Step S120: infrared monitoring picture is sent to buffer storage.
Step S130: when detect in infrared monitoring picture there is new thermal source compared with thermodynamics frame time, the video frequency pick-up head controlled in bimodulus camera obtains video monitoring picture.
Step S140: preserve the monitored picture that video frequency pick-up head obtains.
By utilizing the bimodulus camera function of bimodulus camera, the change of thermal source is judged under infrared photography pattern, start and stop video camera pattern is selected according to thermal source change, preserve video monitoring picture, this programme improves the validity of the monitor video of preservation, decrease the preservation of invalid video as far as possible, improve the memory space of storage device in the mode improving the validity of monitor video in quality.
Specifically, for place greatly, daytime is the operating time, and supervisory control system should be do not stop transport to turn, and namely all has mobile object or people at any time in camera, and monitoring is basic without the need to judging, directly preserves; Be then that flow of personnel is little in the evening, now also saves the good period of memory space, but therefore can not close supervisory control system, otherwise be easy to lack lines of evidence when the unexpected time occurs.Therefore this supervisory control system has better effect at night, greatly can save memory space, also can take into account the monitoring to picture simultaneously.
Please refer to Fig. 2, it is the method flow diagram of second embodiment of a kind of automatic start-stop intelligent control method based on bimodulus camera that the embodiment of the present invention provides.Compared with embodiment one, the present embodiment has set up alarming step further, specifically illustrates the determination details of infrared monitoring picture.

Step S230: when detect in infrared monitoring picture there is new thermal source compared with thermodynamics frame time, the video frequency pick-up head controlled in bimodulus camera obtains video monitoring picture.
Under normal unmanned state, arranging thermodynamics frame, is generally speaking exist unmanned state, gathers thermal source frame by infrared camera.When detecting infrared monitoring picture, the interval that is detected as in infrared monitoring picture is detected, and the interval frame number that interval is detected is 2 ~ 8 frames.Interval is detected can improve detection efficiency, and the mode detected with a kind of periodic intervals detects infrared monitoring picture.Interval frame number is 2 ~ 8 frames, can be specifically 2 frames, 5 frames or 8 frames, certainly if the poor place of Security alert, larger interval frame number can be adopted, the frame per second of such as 30fps, can consider that, with 1 second for one-period, interval frame number is 29 frames namely, if the ability of graphics process is enough, every frame all carries out detecting also being fine.
Step S240: preserve the monitored picture that video frequency pick-up head obtains.
Step S250: when detect the period at nobody in infrared monitoring picture there is new thermal source compared with thermodynamics frame time, send alarm signal.
Generally speaking daytime can not give the alarm, if note abnormalities evening, namely gives the alarm to Control Room or defendance room, is processed as the case may be by guard.
Step S260: when infrared monitored picture detects that temperature and size all exceed the thermal source of critical value, send alarm signal.
This step is for detecting fire alarm, and the judgement of temperature and size is to reduce false alarm, and such as human body thermal source, cigarette end thermal source etc. do not include alarm range in.
In sum, by utilizing the bimodulus camera function of bimodulus camera, the change of thermal source is judged under infrared photography pattern, start and stop video camera pattern is selected according to thermal source change, preserve video monitoring picture, this programme improves the validity of the monitor video of preservation, decreases the preservation of invalid video as far as possible, improves the memory space of storage device in the mode improving the validity of monitor video in quality.Achieve simultaneously and the testing and alarm with fire alarm is swarmed into unknown object.
