Description
Technical field
The present invention relates to a kind of digital monitor system based on case detecting.
Background technology
Current digital monitor system is a usefulness as monitoring still, by the visual file that supervises or record a video of operating personnel; Or the time that preestablishes do and regularly pre-record, can't initiatively detect the generation of hazard event, and also quite arduous at image accessing afterwards, must consult institute's image data of possible period, be unfavorable for tracing afterwards.This shows that there are many disappearances in above-mentioned common digital monitor system, demands urgently being improved.
Summary of the invention
The objective of the invention is to be to provide a kind of image of pre-recording that utilizes incident cognitive techniques and temporality, initiatively detect the generation of incident, and the time section of record incident generation, can consult the digital monitor system based on case detecting of coherent video data again fast afterwards.
Main technical schemes of the present invention is: should be based on the digital monitor system of case detecting, mainly by image extraction module, the case detecting module, incident prediction module and event response mechanism module constitute, this image extraction module is that camera lens and camera mounting are located at the place that desire is monitored, cooperate the network video conveyer that image is sent to the remote monitoring computer, and the remote monitoring computer is to confirm in the present image whether particular event to take place by the case detecting module, in case detect specific incident, can see through earlier the event response mechanism module signal of making a response, the prediction of startup incident then module will form the process of complete event always under the image record of a bit of time till now before temporary transient the storage, sort out the inquiry of being convenient to afterwards with time and kind of event.
Digital monitor system based on case detecting of the present invention relatively has following advantage mutually with prior art:
1, except the function that common supervisory control system can be provided, and add the incident cognitive techniques, but the Auto-Sensing particular event, and and then take appropriate action.
2, noted down file for particular event,, accelerate the speed that the monitor staff handles, and can alleviate monitor staff's burden with the time of saving the image storage area and consulting the image archives afterwards.
3, when particular event takes place, can initiatively send warning message to the user by system, with the generation of prevention injury or loss;
4, the case detecting module can be wanted the kind of event detected according to specifically being used for defining, and makes the present invention can be applied in different fields.
Description of drawings
Below in conjunction with a preferred embodiment and accompanying drawing thereof, the present invention is described in further detail.
Fig. 1 is the Organization Chart of one embodiment of the invention;
Fig. 2 is a module diagram embodiment illustrated in fig. 1.
Embodiment
As shown in Figure 1 and Figure 2, digital monitor system provided by the present invention is made of image extraction module 21, case detecting module 23, incident prediction module 24 and event response mechanism module 25.
Described image extraction module 21 comprises camera lens and 12 liang of groups of video camera and network video conveyer 13, wherein a set of shots and video camera 12 are taken crossing full-view image (the back photograph that contains traffic lights and vehicle), another group comprises that according to image car plate is (if take the camera lens of crossing full-view image and the enough big words of car plate resolution in the video camera 12 clearly after then taking nearer vehicle, this group just can be set up), this network video conveyer 13 can transmit full-view image always.As shown in Figure 1, vehicle perceptron 11 is arranged under the road surface of crossroad, when vehicle perceptron 11 perception vehicles arrive, just can be sent to remote monitoring computer 14 by network video conveyer 13 according to image behind the vehicle,, and except using network video conveyer 13, also can be located near the guarded region by a computer rack, collocation Frame Grabber and TCP/IP network transmission function equally can be sent to image remote monitoring computer 14.
Described case detecting module 23 contains vehicle perceptron 11 and case detecting program, vehicle perceptron 11 is used for the appearance of detecting vehicle, and cooperate with image extraction module 21 and to transmit image, the case detecting program then is after the vehicle license plate image is done number plate recognition, detect stolen car according to the information and the image information of vehicle perceptron 11 again, incident such as over-speed vehicles and vehicles running red light, at the variety of event prioritized, in case detect particular event, just can start event response mechanism module 25, the incident of detecting is made suitable reaction (remote monitoring computer 14 sound that can give a warning for example, or even transmit when detecting stolen car news in brief to policeman's mobile phone and control the traffic lights at next crossing), and startup incident prediction module 24, the time section that this incident took place is noted down, so that inquiry in the future, this vehicle perceptron 11 can be that all kinds of inductors are detected object or incident, as induction coil, infrared ray/laser inductor, door and window opens and closes inductor or smog/light sensor etc., also can be to detect object or incident with the program software of image processing.
Can temporalities the pre-record image of a bit of time of described incident prediction module 24, pre-recording of this temporality is along with the time keeps before the image of one section set time length till now always, when receiving the notice of case detecting module 24, just these temporary transient images that store are stored the process that forms complete event for a long time, and be convenient to inquire about afterwards with time and kind of event classification.
When digital monitor system provided by the present invention is applied on the traffic monitoring, described incident prediction module 24 is except getting off the event record that detects, it also can keep in the result and the capture time of each number plate recognition get off, because the incident of picture over-speed vehicles detecting, the capture time that first on same vehicle or former must be arranged, just there is way to calculate its speed of a motor vehicle, and in case detect particular event, just the data of keeping in can be taken out reference, just can learn the time section that this incident takes place, the data of will keeping in is then all deleted, in addition, these case detecting module 23 visual application demands are changed, be used in road/crossing monitoring and can detect stolen car, over-speed vehicles and vehicles running red light etc., be used on the building guard monitor and can detect movement of objects, incidents such as door and window switching and suspicious light provide the function of initiatively detecting incident that great security personnel's effect will be arranged.
