Embodiment 1
The interference source intelligent shielding device being applied to Forest Fire Monitoring System of the present invention, its structure comprises:
Picture pick-up device, obtains image for taking required guarded region, and is sent to processor;
Numerical control console, under the control of a processor, drives picture pick-up device to realize the change of shooting angle;
Display end, for showing image;
Processor, for all scopes that the field angle of picture pick-up device can be covered, is divided into the screen unit of the identical rectangle of multiple size with the form of numbering, set up with the data model of screen unit geocoding and store; And for the making video transmitted by picture pick-up device being gone out panorama sketch and storing, the information of shooting angles that stored images is corresponding simultaneously; When being elected to the image in middle panorama sketch, find out the screen unit scope that current image is corresponding in data model; And select frame by the grid of display end, by not needing the screen unit carrying out monitoring to choose in image, being listed in the shielding area that do not need to carry out condition of a fire monitoring and being stored;
Wherein, grid selects frame to be the choice box that user carries out when selected shielding area operates, a grid selects frame to be made up of multiple grid, grid selects the size of each grid in frame identical with screen unit size, and the size of the screen unit of the wherein size meeting system for tracking setting of each grid changes and changes.
Load module, for inputting instruction.
Picture pick-up device comprises infrared thermal imager and Penetrating Fog video camera.Infrared thermal imager is a kind of photosensory assembly detecting far infrared spectrum, and its sensor can be refrigeration photosensory assembly or non-brake method photosensory assembly, can the far infrared that discharges of detected object adstante febre.Forest fire monitoring system is mainly by this sensor detection condition of a fire.Penetrating Fog video camera gathers the near infrared spectrum imaging of environment, and the optical characteristics utilizing infrared ray can penetrate smog provides the grayscale image of forest environment high definition, allows system still can see on-the-spot sharp image when dense fog or breaking out of fire cause dense smoke to gather.
Processor is provided with condition of a fire alarm modules, for the image information transmitted according to picture pick-up device, automatically identify and carry out condition of a fire warning, fire alarm mark is identified at relevant position on map, if choose this fire alarm mark, then demonstrate the real-time imaging comprising this region at display end.
Processor also comprises fire alarm shroud module, occurs the position of condition of a fire warning sign for non-required guarded region because there is interference source, and selecting frame to be chosen to be by grid does not need to carry out in the shielding area of condition of a fire monitoring, and corresponding data is stored.
Processor also comprises intelligent selection module, if be less than a screen unit for making the distance of the image corresponding movement in data model obtained in real time because picture pick-up device rotates, when causing grid to select the grid in frame and screen unit to occur situation about staggering, a screen unit in Intelligent Selection.
The above-mentioned screen method being applied to the interference source intelligent shielding device of Forest Fire Monitoring System, as shown in process flow diagram in Fig. 1, comprises two kinds of mode of operations: panorama sketch mask pattern and fire wrong report mask pattern, wherein panorama sketch mask pattern comprises the steps:
Step one, set up data model: all scopes that the field angle of picture pick-up device can be covered, be divided into the screen unit of the identical rectangle of multiple size with the form of numbering, each screen unit has unique numbering, thus sets up with the data model of screen unit geocoding and store; The horizontal and vertical size of described each screen unit by 1 pixel to covering the number of pixels that can produce of whole picture pick-up device when shooting one frame picture;
Step 2, obtains panorama sketch: the image being taken required guarded region by picture pick-up device, and generates panorama sketch and store, the information of shooting angles that stored images is corresponding simultaneously;
Step 3, shielding area is selected: select to need the image carrying out masking operation from panorama sketch, according to the corresponding information of shooting angles of this image, finds out the screen unit scope that current image is corresponding in data model; Select frame by grid, will in image, not need the screen unit carrying out the scope monitored to choose, and listed in the shielding area not needing to carry out condition of a fire monitoring; Described grid selects the size of each grid in frame identical with screen unit size; Described grid selects frame to be the choice box that user carries out when selected shielding area operates;
Step 4, shielding area data store: the shielding area selected in step 3 and information of shooting angles corresponding to this image are stored.
And report mask pattern by mistake by the fire that condition of a fire alarm modules is corresponding, specifically comprise the steps:
A), when having the doubtful condition of a fire to occur in unmasked region, there is fire alarm mark in the doubtful condition of a fire position of condition of a fire alarm modules on the map interface of display end;
B), choose condition of a fire warning sign namely to enter fire wrong report mask pattern, display end demonstrates the history image comprising this region and photograph when finding the doubtful condition of a fire;
C), judge whether region shown by fire alarm mark is required guarded region, if not, then listed according to the method for step 3 in the shielding area not needing to carry out condition of a fire monitoring, and corresponding data are stored; If so, then do not carry out shielding and select operation, and notify that related personnel takes corresponding fire handling procedure.
The concrete principle that in step one, data model is set up is: all regional extents that picture pick-up device field angle on The Cloud Terrace can cover are divided into multiple square type shield ranges with the form of numbering, square type size with the field angle of this picture pick-up device and measurand size for standard, size is can just the minimum measured object of overlay device in the visual field of all observation angles be moderate, we call screen unit these rectangles, and the horizontal and vertical size of each screen unit can by 1 pixel so that cover the number of pixels that can produce of whole picture pick-up device when shooting one frame picture.Such as: picture pick-up device shooting resolution is 320x240 pixel, and that minimum screen unit can be 1 pixel x 1 pixel, and maximum screen unit can be then 320 pixel x 240 pixels.Fig. 2 is the schematic diagram of this partitioning scheme, because numerical control console is machinery that is vertical and transverse rotation, the picture that the picture pick-up device linked with numerical control console can photograph seamlessly on a ball must piece displaying together, so we used the data model of ball-type segmentation as screen unit geocoding.Ball-type center is The Cloud Terrace and picture pick-up device in fig. 2, and spherical surface show be wherein one row shielding community, each screen unit has unique numbering in a database.For easy viewing, we do not draw all screen units, because the size of screen unit can change with different system demand, so when practical application, in figure spherome surface any one grid in be to contain the screen unit being less than one or more than one.We show wherein one group of screen unit with oblique line in fig. 2, and on gray-scale map, the display of cross spider grid is the screen unit that we set.
When shielding area in step 3 is selected, because display end is in order to maintain user friendly, so the grid providing public affairs whole allows user select shield ranges, but because numerical control console arbitrarily can change shooting angle, cause the length of side that may move when rotating less than a screen unit, time like this on the screen unit of the correspondence of data model is added to real-time imaging, by the problem causing display end grid to select the screen unit on the grid of frame and data model not exclusively overlapping, namely grid selects the grid in frame and screen unit to stagger, can apply like this present invention with intelligent selection module, controlling grid selects frame to have the following two kinds mode of operation:
Pattern one, grid selects frame position to fix, the grid of display end select frame be comprise multiple complete grid select frame.As shown in Figure 3, empty wire frame representation grid selects frame, and continuous lines frame table shows the frame of screen unit.Now occur that grid selects one of them grid of frame on data model, matched the problem (also may there is grid and select frame grid and the overlapping situation of two screen units) of 4 not exclusively overlapping screen units.When processing this problem, default is select the maximum screen unit of overlapping area to be shielded, and ignores the overlapping screen unit of other less areas.Such as in Fig. 3, if click upper right side that grid, then default is that rightmost that second screen unit arranging maximum with its overlapping area is selected.If overlapping area is identical, for a grid and the overlapping situation of two screen units, then select that screen unit of the left side or top, for a grid and the overlapping situation of four screen units, select that screen unit upper left.
Pattern two, grid selects frame position can move with picture pick-up device.Grid selects frame can carry out moving to mate completely with the screen unit on data model.Concrete, processor can be added on image all screen units after receiving the address of screen unit, grid select frame then can in-plane displancement to the coverage being engaged in screen unit on data model, that is grid position selecting frame can move to its each grid just to overlap with a screen unit.When using this pattern, as shown in Figure 4, because grid selects the screen unit that each grid correspondence one of frame is complete, if intend screen, some is positioned at picture edge and a part of overflows beyond picture, such as, in Fig. 4 grid in the lower right corner, operating personnel, when clicking this grid, also can shield in the extraneous scope of picture together.May be there is the forest environment of the true condition of a fire when screen unit is established too large outside meeting error masking picture in this phenomenon and operating personnel do not know.Solution is that the screen unit at picture edge less than an integral lattice is forbidden automatically, namely conceals the region that imperfect grid that grid selects the periphery of frame to occur is corresponding.The imperfect grid being shown as oblique line in Fig. 5 can be hidden, describe edge disabled after, operating personnel can only see that grid selects all complete grid in frame, and that just can guarantee that operating personnel just the regions shield of the true condition of a fire can not may fall periphery because of the scene do not seen clearly outside current picture.
It should be noted that the screen unit of Fig. 3-Fig. 5 is all that screen unit size when reality uses is generally 5 pixel x 5 pixel ~ 20 pixel x 20 pixels in order to easily understand and easily watch and draw larger.
The method of operating of panorama sketch mask pattern and fire wrong report mask pattern is illustrated below in conjunction with accompanying drawing.
Panorama sketch mask pattern: is as shown in Figure 6 a real-time imaging of display end display, demonstrates select frame, as the netted segmentation on Fig. 6 image for shielding the grid selected at display end.We wish to shield the crane shown in picture, when operating personnel choose the region at crane place by load module, system can with the shield ranges selected by the display of highlighted green, in the present embodiment, highlighted green area is represented with oblique line, as shown in Figure 7, T-shaped hatched example areas is exactly the crane that we wish to shield.Click " ignoring " button afterwards and just the scope of needs shielding can be sent to processor, thus listed in shielding area scope, by processor, this shielding area is stored.
Fire wrong report mask pattern:
1) as shown in Figure 8, first on map interface, operating personnel click fire alarm mark by load module;
2) enter the condition of a fire inspect pattern, there is infrared ray thermal map and Penetrating Fog shooting figure in interface, as shown in Figure 9, the figure on the left side is infrared ray thermal map, the right be Penetrating Fog shooting figure.The warning place that managerial personnel inspect the fire alarm frame display of rear discovery hatched example areas is not forest zone, but a buildings, the rectangle grid of picture Oxford gray is the scope that system has shielded.When selecting shield ranges, only adopting the image of the picture pick-up device possessing intelligence identification condition of a fire ability without exception, in the present embodiment, have employed the infrared ray thermal map of infrared thermal imager as reference picture.In other intelligent visible ray condition of a fire identification system, the image of visible image capturing head can be used as reference picture.
3) operating personnel click the fire alarm frame of hatched example areas on picture, and this grid can become cross spider fill area, and representative is chosen, as shown in Figure 10.
4) operating personnel click " ignoring " button, just the shield ranges chosen can be sent to processor, thus be listed in shielding area scope, be stored by this shielding area by processor.After having write, this newly-increased shield ranges can become the grid of filling with the Dark grey that other shielding areas are the same, as shown in figure 11.
It is emphasized that this interference source Shielding plan except the infra-red thermal imaging forest fire monitoring system being applicable to the present embodiment, also be applicable to any take picture pick-up device as the system of data acquisition end simultaneously, has more than the application being limited to infra-red thermal imaging picture pick-up device.The present embodiment mainly describes the uniqueness of shielding harness, describes for infra-red thermal imaging video camera so adopt, and other picture pick-up devices based on optical principle imaging are all suitable for interference source intelligent shielding method of the present invention and device.Native system is except shielding constant interference thermal source, also can shield the object of interference visible light video Forest Fire Monitoring System, comprise and be not limited to the red flag waved, large-scale outdoor LED screen, the variation in time such as smog of factory chimney but the interference source of geographic position less constant.
