Wherein, it is that the user selectes the shielding area choice box in when operation that grid selects frame, a grid selects frame to be comprised of a plurality of grid, grid selects the size of each grid in the frame identical with the screen unit size, and wherein the size of the screen unit of the size of each grid meeting system for tracking setting changes and changes.
Load module is used for the input instruction.
Picture pick-up device comprises infrared thermal imager and Penetrating Fog video camera.Infrared thermal imager is a kind of photosensory assembly of surveying far infrared spectrum, and its sensor can be refrigeration photosensory assembly or non-refrigeration photosensory assembly, the far infrared that can the detected object adstante febre discharges.Forest fire monitoring system is mainly surveyed the condition of a fire with this sensor.The Penetrating Fog video camera gathers the near infrared spectrum imaging of environment, and the optical characteristics of 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, be used for the image information that transmits according to picture pick-up device, automatically identify and carry out the condition of a fire and report to the police, the fire alarm sign is identified at relevant position on the map, if choose this fire alarm sign, then demonstrate at display end and comprise this regional real-time imaging.
Processor also comprises fire alarm shroud module, is used for condition of a fire warning sign appears in non-required guarded region because interference source occurring position, and selecting frame that it is chosen to be by grid does not need to carry out in the shielding area of condition of a fire monitoring, and with corresponding data storage.
Processor also comprises the Intelligence Selection module, if be used for because picture pick-up device rotates so that the image that obtains in real time in the corresponding mobile distance of data model less than a screen unit, when causing grid to select the situation that to stagger appear in grid in the frame and screen unit, screen unit in the Intelligent Selection.
The above-mentioned screen method that is applied to the interference source intelligent shielding device of Forest Fire Monitoring System shown in process flow diagram among Fig. 1, comprises two kinds of mode of operations: panorama sketch mask pattern and fire wrong report mask pattern, wherein the panorama sketch mask pattern comprises the steps:
Step 1, set up data model: all scopes that can cover the field angle of picture pick-up device, form with numbering is divided into the screen unit of the identical rectangle of a plurality of sizes, and each screen unit has unique numbering, thereby sets up data model and storage with the screen unit geocoding; 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 taking a frame picture;
Step 3, shielding area is selected: select to carry out the image of masking operation from panorama sketch, according to the corresponding information of shooting angles of this image, find out the screen unit scope of current image correspondence in data model; Select frame by grid, the screen unit of the scope that do not need in the image to monitor is chosen, and list it in do not need to carry out condition of a fire monitoring shielding area; Described grid selects the size of each grid in the frame identical with the screen unit size; It is that the user selectes the shielding area choice box in when operation that described grid selects frame;
Step 4, shielding area data storage: shielding area and information of shooting angles corresponding to this image selected in the step 3 are stored.
And by fire wrong report mask pattern corresponding to condition of a fire alarm modules, specifically comprise the steps:
A), when having the doubtful condition of a fire to occur at non-shielding area, the fire alarm sign appears 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 and comprise the history image that this zone photographs when finding the doubtful condition of a fire;
C), judge whether the shown zone of fire alarm sign is required guarded region, if not, then according to the method for step 3 it being listed in does not need to carry out in the shielding area of condition of a fire monitoring, and with corresponding data storage; If so, then do not shield and select operation, and notify the related personnel to take corresponding fire handling procedure.
The concrete principle that data model is set up in the step 1 is: the All Ranges scope that can cover picture pick-up device field angle on the The Cloud Terrace is divided into a plurality of square type shield ranges with the form of numbering, square type size is take the field angle of this picture pick-up device and measurand size as standard, size take can just the minimum measured object of overlay device in the visual field of all observation angles as moderate, we call screen unit to these rectangles, and the horizontal and vertical size of each screen unit can be by 1 pixel so that cover the number of pixels that can produce of whole picture pick-up device when taking a frame picture.For example: it is the 320x240 pixel that picture pick-up device is taken resolution, and that minimum screen unit can be 1 pixel x, 1 pixel, and maximum screen unit then can be 320 pixel x, 240 pixels.Fig. 2 is the synoptic diagram of this partitioning scheme, because numerical control console is the machinery of vertical and transverse rotation, the picture that can photograph with the picture pick-up device of numerical control console interlock is must be on a ball seamless pieces displaying together, so we have used ball-type to cut apart data model as the screen unit geocoding.The ball-type center is The Cloud Terrace and picture pick-up device in Fig. 2, and what show at spherical surface is a row shielding residential quarter wherein, and each screen unit has unique numbering in database.For watching easily, we do not draw all screen units, because the size of screen unit can change with the different system demand, so when practical application, be to have comprised to be less than one or more than one screen unit in any one grid of spherome surface among the figure.We cover the unit to a group screen wherein and show that with oblique line what the cross spider grid showed on gray-scale map is the screen unit that we set in Fig. 2.
When the shielding area in step 3 is selected, because display end is in order to keep user friendly, so provide the whole grid of public affairs by the user selection shield ranges, but because numerical control console can arbitrarily change shooting angle, the length of side that may a screen unit of mobile less than when causing rotating, like this when the screen unit of the correspondence of data model is added on the real-time imaging, to cause the display end grid to select grid and the incomplete overlapping problem of the screen unit on the data model of frame, be that grid selects grid and screen unit in the frame to stagger, can use like this present invention with the Intelligence Selection module, control grid select frame to have following two kinds of mode of operations:
Pattern one, grid select the frame position to fix, and selecting frame at the grid of display end is the frame that selects that comprises a plurality of complete grid.As shown in Figure 3, empty wire frame representation grid selects frame, continuously the frame of wire frame representation screen unit.The problem (also may exist grid to select a grid and two situations that screen unit is overlapping of frame) that one of them grid that grid selects frame has matched 4 incomplete overlapping screen units at data model has appearred this moment.When this problem of processing, default is shielded for the screen unit of selecting the overlapping area maximum, and ignores the overlapping screen unit of other less areas.For example as among Fig. 3, if click that grid of upper right side, then default is that second screen unit of that row of rightmost of area maximum overlapping with it is selected.If overlapping area is identical, for a grid and two situations that screen unit is overlapping, then select that screen unit of the left side or top, for a grid and four situations that screen unit is overlapping, select upper left that screen unit.
Pattern two, grid select the frame position to move with picture pick-up device.Grid select frame can move with data model on screen unit mate fully.Concrete, processor can be added to all screen units on the image after receiving the address of screen unit, grid select frame then can in-plane displancement to the coverage that is engaged in screen unit on the data model, that is to say that grid selects frame can move to the position that its each grid just overlaps with a screen unit.When using this pattern, as shown in Figure 4, because grid selects the corresponding complete screen unit of each grid of frame, some is positioned at the picture edge and some is overflowed beyond the picture if intend screen, the grid in the lower right corner among Fig. 4 for example, operating personnel can be also shielding together in the extraneous scope of picture when clicking this grid.The forest environment of the true condition of a fire can error masking when screen unit is established too greatly may occur outside the picture and operating personnel do not know in this phenomenon.Solution is automatically forbidding at the screen unit of picture edge less than one integral lattice, namely having hidden zone corresponding to imperfect grid that grid selects the periphery of frame to occur.The imperfect grid that is shown as oblique line among Fig. 5 can be hidden, after having illustrated that the edge is disabled, operating personnel can only see that grid selects all complete grid in the frame, and that just can guarantee that operating personnel can just may not exist the regions shield of the true condition of a fire to fall because of not seeing the outer scene of current picture clearly to the periphery.
Screen unit that it should be noted that Fig. 3-Fig. 5 all is to draw greatlyr in order to understand easily with watching easily, and the screen unit size during actual the use is generally 5 pixel x, 5 pixels ~ 20 pixel x, 20 pixels.
Specify the method for operating of panorama sketch mask pattern and fire wrong report mask pattern below in conjunction with accompanying drawing.
The panorama sketch mask pattern: as shown in Figure 6, be the real-time imaging that display end shows, the grid that demonstrates for shielding selection usefulness at display end selects frame, such as netted the cutting apart on Fig. 6 image.We wish to shield the crane that shows in the picture, choose the zone at crane place by load module as operating personnel, system can show with highlighted green selected shield ranges, in the present embodiment, represent highlighted green area with oblique line, as shown in Figure 7, T-shaped hatched example areas is exactly that we wish the crane that shields.Click afterwards " ignoring " button and just can send to processor to the scope of needs shielding, thereby list it in shielding area scope, by processor this shielding area is stored.
Fire wrong report mask pattern:
1) as shown in Figure 8, at first on map interface, operating personnel click the fire alarm sign by load module;
2) enter the condition of a fire and inspect pattern, infrared ray thermal map and Penetrating Fog shooting figure appear in the interface, and as shown in Figure 9, the figure on the left side is the infrared ray thermal map, the right be Penetrating Fog shooting figure.The place of alarm that managerial personnel inspect the fire alarm frame demonstration of rear discovery hatched example areas is not the forest zone, but a buildings, the rectangle grid of picture Oxford gray is the scope that system has shielded.When selecting shield ranges, only adopt the image of the picture pick-up device that possesses intelligence identification condition of a fire ability without exception, in the present embodiment, adopted the infrared ray thermal map of infrared thermal imager as the reference picture.In other intelligent visible light condition of a fire identification system, can use the image of visible image capturing head as the reference picture.
3) operating personnel click the fire alarm frame of hatched example areas on the picture, and this grid can become the cross spider fill area, and representative is chosen, as shown in figure 10.
4) operating personnel click " ignoring " button, just can send to processor to the shield ranges of choosing, thereby list it in shielding area scope, by processor this shielding area are stored.Write after finishing and newly-increased shield ranges can become the grid of filling with the same Dark grey of other shielding areas, as shown in figure 11.
It is emphasized that this interference source Shielding plan except the infra-red thermal imaging forest fire monitoring system that is applicable to present embodiment, also be applicable to simultaneously anyly take the system of picture pick-up device as the data acquisition end, have more than the application that is limited to the infra-red thermal imaging picture pick-up device.Present embodiment mainly is the uniqueness of describing shielding harness, describes as an example of the infra-red thermal imaging video camera example so adopt, and other picture pick-up devices based on the optical principle imaging all are 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 that disturbs the visible light video Forest Fire Monitoring System, the smog of the red flag that comprises and be not limited to wave, large-scale outdoor LED screen, factory chimney etc. change but the general constant interference source in geographic position in time.
