CSRC station 14 comprises the hardware and software that is set to carry out function of the present invention as described herein.For example, CSRC station 14 comprises display, CPU, volatibility and nonvolatile memory, input-output apparatus, and the network interface that is used for CSRC station 14 is coupled to communication network 16.Network interface can be wired or wireless interface.CSRC station 14 can be any suitable computing equipment of the known suitable operating system of operation prior art, as personal computer, small-sized or mainframe computer, personal digital assistant (" PDA ") or the like.Though shown single CSRC station 14,, do so just for the present invention is described more easily.Should be appreciated that, can provide a plurality of CSRC station 14 at a remote location, in the case, use a plurality of operators to monitor alarm from a plurality of monitored positions 12 by the scheme of more complicated.
In operation, relatively explain, when trigger event takes place,, will be transferred to CSRC station 14 from monitored position 12 corresponding to the view data of an image or a series of images by communication network 16 as following.The 14 pairs of view data in CSRC station are handled, and the one or more images of having handled on its display screen are presented to the operator.Whether this image or these images allow the operator to assess trigger event is true alarm.
Monitored position 12 comprises one or more video cameras 18 and the transducer 20 that communicates with wired or wireless mode and panel 22.Transducer 20 can be any transducer that can trigger alarm, include but not limited to wired and wireless motion sensor, heat sensor, infrared ray sensor, glass break sensors, microwave remote sensor, sonic transducer, ultrasonic sensor, sound transducer, photoelectric sensor, pressure pad/transducer and Magnetic Sensor.Video camera 18 is set to use wired or wireless communication and panel 22 to communicate.Video camera 18 can be to be applicable to any video camera that is transferred to the image at alarm monitoring station, center 14 after seizure is used for.Suitable video camera 18 includes but not limited to, catches the static or motion cameras of black and white and/or coloured image.Video camera 18 can be installed regularly, also can be to shake/tilt/zoom type.Video camera 18 can be set to provide continuous video or rest image to present to panel 22, also can be configured to catch when triggering transducer 20 image.Video camera 18 can provide DID to panel 22, also can provide simulated image data to panel 22.Under latter event, the electronics in the panel 22 makes the simulated image data digitlization, so that be transferred to CSRC station 14 later on.
In operation, panel 22 helps the communication from monitored position 12 to CSRC station 14, so that the view data of being caught by video camera 18 can be processed and be presented on the display at CSRC station 14, so that analyzed and operated by the operator of correspondence.
As noted above, the view data that sends to CSRC station 14 can be based on the triggering alarm events, perhaps the regular image that just transmits.For example, can regularly catch image, so that catch alarm image in advance with continuous circulation.In any case, imagination with the image data transmission of a series of images to CSRC station 14, so that show or handle subsequently.In the previous case, image sequence can provide in single display window, as the form with thumbnail image, whether has described such activity so that the operator can distinguish image, promptly guarantee and to take other action in monitored position, as law enforcement agency or guardian of the peace's visit.Under latter event, as will be described in detail below, CSRC station 14 or some other treatment facility (not shown) are handled image, the analysis of carrying out with the further person of simplifying the operation.
Described and obtained view data and view data is handled to create display image, so that alarm events is carried out the example of visual checking.With reference to Fig. 1 and 2, first exemplary method of creating display image has been described.When alarm events takes place, be transferred to CSRC station 14 from panel 22 corresponding to the view data of image 24a-24e.14 pairs of images of monitoring station are handled, and deduct the view data of each image from the view data of previous image, to create four number of sub images 26a-26d.The consequent image 26a-26d that has handled is presented on the monitoring station 14, so that the operator to need can determine the disappearance or the Conditions of further action.Under the situation of method shown in Figure 2, each subimage all is the difference between the image that obtained by video camera 18 and the previous image of being caught by this video camera.By presenting four image 26a-26d that handled to the operator apace, the operator can judge whether the whatsit that becomes and do not exist or lack is arranged in the image of catching in the previous image that obtains.
For example, Fig. 3 A, 3B and 3C have shown two images that obtain continuously and three examples of the image handled, as may be about any in method shown in Figure 2 or other exemplary method as described herein and take place.Fig. 3 A has shown frame 28, wherein, people 30, table 32 and box 34 is arranged.Such image can corresponding to, for example, the image 24a among Fig. 2.Be shown as the image that the next one of the frame 36 among Fig. 3 B is caught, only shown the existence of table 32 and target 38.According to an embodiment, frame 28 and 36 operators that can present on the monitoring station 14 can allow the operator visually judge and not have people 30 and box 34 disappearances in frame 36.This may be significant, requires the operator to warn security or the personnel of law enforcement agency.Frame 36 also can be corresponding to the image 24b among Fig. 2.Under these circumstances, monitoring station 14 will be handled corresponding to the frame 28 and 36 image 24a and the view data of 24b that are shown as respectively among Fig. 3 A and the 3B, to obtain corresponding to the frame of having handled 40 shown in Fig. 3 C of the image 26a that has handled among Fig. 2.Under these circumstances, will provide the image of having handled that has shown people 30, box 34 and target 38 to the operator.
It should be noted that, should be realized that, (its image comes across in the follow-up frame when the subtracted image data, rather than in the frame of front) time, as the target among Fig. 3 B 38, may produce negative value, so that resulting data is not displayable as image, because the corresponding data represented value that is lower than black level value.Yet the data of the whole image of having handled can be scaled, so that all data can present visibly, perhaps, the negative value of the view data of having handled shows as their absolute value.For example, if the image of having handled will be with gray level display on CSRC station 14, wherein each pixel all is represented as the value between the 0-255, corresponding to the data of the image of having handled can be scaled in case all pixels all in this scope, perhaps, can be used as absolute value and present owing to corresponding to appearing in the follow-up frame or the object that lacks from follow-up frame is treated to the pixel with negative value.More detailed example is provided below.In addition, it should be noted that further image data processing or the consequent image of having handled, be present in noise in the image with minimizing.It should be noted that convergent-divergent, absolute value and noise trim process are applicable to any in discussed herein and the image processing method described, be not limited only to the method described in Fig. 2.
Another exemplary method of using the 14 pairs of view data in CSRC station to handle and present to the operator image of having handled is described below with reference to Fig. 4.Supposed to take place to cause catching the alarm events of image 24a-24e.According to the method, further the image 26a-26d that has handled is handled, to create the single image of having handled 42 of representative corresponding to the addition of the data of image 26a-26d.The consequent synthetic image of having handled 42 is shown to the operator on CSRC station 14.Under the preferable case, this layout can make single image be presented on the CSRC station 14, making the operator judge whether to exist people, object or the like apace, so that whether the operator can just should call out security or the personnel of law enforcement agency judge to monitored position.For example,, in the image of having handled 42, described the people in the room of passing by, shown the different position of people in image, thereby made the operator judge that apace the people passes monitored position though do not show.Based on this situation, the operator can visual apace this situation also just may need anything further to judge.
Describe based on the single image of having handled of the creation of image of catching below with reference to Fig. 5, so that another example of the method that on monitoring station 14, shows.In the method, 24a-24e handles to image, so that image 24a serves as starting point, deducts the data of each follow-up image from the view data corresponding to image 24a, then, the result is sued for peace together, to form single image.For example,, and they are handled to the view data of monitoring station 14 transmission corresponding to image 24a-24e by panel 22, to create four number of sub images 44a-44d, wherein, each subimage is all corresponding to the difference between one among image 24a and the image 24b-24e.To sue for peace together corresponding to each the data among the subimage 44a-44d, to create the image of having handled 46.Method shown in Figure 5 is basically with start image, image 24a, and the quantity of remaining image of convergent-divergent, and from image 24a, deduct each follow-up image.Also can carry out the pixel value convergent-divergents to any one among the subimage 44a-44d and/or the image handled 46, noise is subdued and absolute value is handled.
It should be noted that Fig. 2, the image that the one or more image 24a-24e shown in 4 and 5 catch before or after can triggering corresponding to alarm events.For example, image 24a can be the image before the incident, has the image 24b-24e of the remainder of catching after triggering.Be also noted that, the invention is not restricted to catch and handle five images, but can catch and handle the image of any amount.Therefore, should be realized that, use five images of catching just for ease of explanation and understanding.
Although have preset time at interval between the catching of and each image of methods hypothesis in image 24a-24e described shown, this optional situation with reference to figure 2,4 and 5.For example, as shown in Figure 6, can between the catching of image 24a and 24b, insert time delay 48,, or be replaced by time delay 48 so that the image of having handled 50 additionally comprises time delay 48.Time delay 48 can so be set, so that image 24a is based on the catching of trigger event, any incident that takes place in time delay 48 all is captured as image 24b subsequently.For example, the process of running utilizes the people in the zone of motion detector monitoring will cause detector to catch the triggering alarm events, causes catching image 24a, and caught image 24b before the runner can withdraw from this zone.Under the preferable case, this layout has been dwindled the amount of the view data of necessary transmission and processing.As noted above, not outside the predetermined time interval between the catching of image 24a and 24b, to provide time delay 48.On the contrary, time delay 48 can be replaced the predetermined time interval, and can be configured according to different implementations.
Fig. 7 has shown another exemplary method, wherein, can postpone to dwindle the amount of the view data that is transferred to CSRC station 14 and is handled by CSRC station 14 service time.In method shown in Figure 7, between image 24b and 24c, inserted time delay 48, subsequently image 24a-24c is handled, so that image 24a serves as starting point, from image 24a, deduct data corresponding to image 24b and 24c.This layout does not also enter under the situation of video monitoring regional useful at monitored door place the people.By between follow-up image, allowing time delay, can make the people enter the monitoring area, so that can create and show the image of the assessment of usefulness.
So that alarm events is carried out the visual checking, also can so realize the present invention except that presenting one or more images of having handled, when the difference between the image of catching surpasses predetermined threshold value, provide some other indicating device by the operator.Such indicating device can present the form of the visual indication on the display screen, as Pop-up square frame, literal, or icon; Perhaps, also can be the indicating device that separates with display screen, as independent lamp, sound or the like.By this way, can alarm operation person, change enough significantly, the operator should notice carefully that the confession that presents carries out the image of having handled of visual checking.
As noted above, image processing also can comprise the processing of eliminating noise.This can, for example, by the intensity threshold rank is set in process software, when deducting two view data corresponding to two images, have only those pixels just to be shown with the value that surpasses a certain predetermined threshold value with box lunch.In this same texture, the percentage of the sum of the image pixel that can provide to the operator on display screen is provided the sum that surpasses the pixel of noise threshold, and is used as judgement for having great change whether the index of rational expection is arranged between two images that are being compared.This index can be kept in the database, as is kept in the database on the CSRC station 14, is used to the purpose of filing.This index can be used as the basis that compares with predetermined threshold value, so that judge whether enable indicating device, and offers the operator.
As noted above, might in processing procedure, produce negative value by subtraction, and the consequent pixel that can not show, a kind of mode of head it off is convergent-divergent (displacement) image show value.A kind of mode of carrying out this operation is to use following method convergent-divergent pixel:
C＝((A-B)/2)+(R/2)
Wherein, C equals the value of the pixel that will show, A is the value of the pixel A in first image such as image 24a, and B equals the value of pixel of the correspondence of the image to be deducted such as image 24b, and R is other total size of level in two images.Extra if desired contrast, then can add extra zoom factor as follows:
C＝(x(A-B)/2)+(R/2)
Wherein, x is the zoom factor greater than 1.If x is such, so that C〉R, so, can the operating limit algorithm, as: if C〉R, so, C=R, if C＜0, so, C=0.Although contrast level can automatically be determined in the programming software of handling image, but, can expect, contrast level (x) can be adjusted by the operator, for example, by a slide block is provided, or on display screen, provide independent input area or the like in the display window that has shown image.
Under the preferable case, the invention provides a kind of method, system and CSRC station, they are used to carry out image processing, so that use the software application that can reside in the CSRC station 14 to show and visual checking by the operator, do not need a large amount of computing capabilitys to operate.By this way, be used to realize that the programming software of function as described above does not need a large amount of computing capabilitys, because it does not carry out a large amount of Digital Signal Processing (" DSP ").Therefore, the present invention is suitable for realizing with the form of the applet that can reside in the CSRC station 14 and be carried out by CSRC station 14.Certainly, also can in the server of relatively concentrating, provide the software application of having realized function as described above like a cork, so that can handle by server from all images data that one or more monitored positions arrive, be transferred to one or more CSRC station 14 then, so that carry out follow-up visual checking.
