Especially, attribute information drawing section 30 describes to link the level line of the identical absolute altitude attribute on the subject, monochrome information obtaining section 29 obtains monochrome information by each level line of being paid on digital picture, has in addition based on obtained monochrome information to make the change curve preparing department (change curve production unit) 35 of monochrome information change curve and extract the liquid level boundary line information extraction portion (liquid level boundary line information extraction unit) 37 of absolute altitude information of the liquid level boundary line of subject 2 based on the monochrome information change curve.
Next, effect and the effect to the level measurement device that used the image processing apparatus that present embodiment relates to describes.As shown in Figure 3, utilize the monitor camera 3 that is fixed on the riverbed to obtain the image of subject 2.By cable 4 image of obtaining is sent to administrative center 5.The picture signal of obtained subject 2 is saved in from receiving device 11 preserves the medium 19, and be presented in the supervision display screen picture 17 in the administrative center 5.
Synthesizing of obtained digital picture and three-dimensional spatial information, (village well person of outstanding talent controls to use known photo measuring unit, " resolving photo measurement-revised edition ", association is measured by Japan, put down into 12 years), use the 3 d surface model of subject as shown in Figure 4, after the parameter of the locus of obtaining monitor camera 3, camera pose, camera lens focal length value etc., three dimensional space coordinate is transformed to the two dimensional image coordinate system, and can calculate two dimensional image coordinate position corresponding to specified three dimensional space coordinate position.Simultaneously, be presented at this moment in the digital picture that monitors in the display screen picture 17, utilize attribute information to pay portion 27 attribute information of the latitude of subject 2, longitude, absolute altitude is paid on each pixel of digital picture.
Then, by specified scope on digital picture, and in relevant range, describe the level line 10 of certain intervals.Promptly, when specified scope on digital image, use the 3 d surface model of subject 2 as known approaches, and on the surface of subject, obtain after the level line 10 of each specified altitude, use the 3 d surface model of subject to make CG (ComputerGraphic) image, and on the CG of made image generating contour 10.By the digital picture that above-mentioned monitor camera 3 reads in, have the coordinate system identical in theory with the CG image.Thereby the level line 10 based on the 3 d surface model of subject is made also can be depicted on the digital picture.
Next, to obtaining monochrome information, and determine that by relevant monochrome information the method for river level describes by digital picture.Utilize attribute information drawing section 30, generating contour 10 on digital picture, utilize the monochrome information obtaining section 29 of image processing part 13 to obtain the monochrome information on subject surface from digital picture then.Monochrome information is tried to achieve average brightness value by each level line 10, and makes along the curve map of the mean flow rate change curve (the continuous data curve of monochrome information) of absolute altitude direction.Fig. 6 is the curve map of expression mean flow rate change curve, and X-axis is represented the absolute altitude value among Fig. 6, and Y-axis represents to be depicted in the average brightness value of the level line 10 on the subject (part at the bottom of the bridge) 2.
The basic concept of method that is detected the position of the level line corresponding with river level 10 by above-mentioned mean flow rate change curve is, causes the sharp brightness decay when detecting water outlet in the mean flow rate change curve.Thereby, can come to detect river level by detect the position of local pattern (shape) by the mean flow rate change curve corresponding to river level from digital picture.
Here, the principle that is obtained monochrome information by digital picture is described.As described above, in absolute altitude display part 30, make level line according to the 3 d surface model of subject, and, the monochrome information on the level line in monochrome information obtaining section 29, collected.Transform in the image coordinate system isocontour shape as shown in Figure 9, by the set { P|P of stain 1..., P K, P NDecision.Then, grasp with the level line position on related pixel, and isocontour some P in the calculating digital picture coordinate system KBrightness of image ratio value V PK
One example of the computing method of Figure 10 presentation video brightness ratio value, as shown in the figure, square a-b-c-d represents to obtain with a P kEffective range for the brightness value at center.And a pixel of square size and digital picture is consistent, and nine pixels adjacent with square a-b-c-d are and a P kThe pixel groups of being correlated with on the position.In addition, in formula (1), V b iBe the brightness value of the nominated bandwidth B of associated pixel i, AP iRatio for the area that accounts for square a-b-c-d of pixel i.Then, based on the brightness of image ratio value, calculate the level line L shown in the following formula (2) ZiMean picture brightness value MV I (Zi)
Formula (1)
V P K = Σ i = 1 9 ( A P i × V i b ) , K ∈ N . . . ( 1 )
Formula (2)
M V L ( Zi ) = Σ K = 1 N V P K N . . . ( 2 )
High speed processing method when next, the implication information of the spatial data determined by each or three-dimensional spatial information being obtained monochrome information describes.As described above, come computed image brightness ratio value, and based on above-mentioned formula (2), come the computed image average brightness value by the monochrome information of the pixel groups of having determined based on above-mentioned formula (1).In ocean weather station observation, when calculating monochrome information continuously, can be to fixing with the pixel groups that on the implication information of the spatial data of having determined on the two dimensional image or three-dimensional spatial information position, is associated.That is, except that the brightness value information on observation time and subject surface, fix each parameter and (in above-mentioned formula (1) and formula (2), remove bandwidth luminance parameter V b iOutside, fixing whole parameter), this each reference record with implication information that temporarily is kept at the spatial data in the register or pixel groups that three-dimensional spatial information is associated between relative position relation.Promptly, when handling from seasonal effect in time series digital picture that fixing image unit is obtained, the above-mentioned parameter of double counting just can calculate the image analysis result and only the monochrome information parameter is updated in the time of need not reading in new images in the formula at every turn, therefore can realize the high speed processing of digital picture.
Fig. 7 is the curve map of the characteristic of expression mean flow rate change curve, detects the waveform patterns of relevant characteristic, and detects river level.For the waveform of the characteristic that quantizes to be correlated with and define the parameter of waveform patterns, can use the pattern of each CALCULATION OF PARAMETERS formula in calculating between designation area on the mean flow rate change curve quantitatively.And the parameter shown in the figure is an example that is used for quantized waveform, also can use other parameter.Each parameter among the figure is defined as follows.B: position, the B of interval minimum brightness value L: interval left margin point, B R: interval right margin point, T L: B and B LBetween position, the T of highest brightness value R: B and B RBetween position, the ap of highest brightness value: curve pitch angle, the aL at some p place: line segment T LThe pitch angle of-B, aR: line segment T RThe pitch angle of-B.
Then, in liquid level boundary line information extraction portion 37, specify and necessarily intervally also to scan the mean flow rate change curve, and detect the maximally related interval of model curve shape with above-mentioned predefined the parameter of the curve from the interval of being scanned.And then, with reference to predefined curvilinear characteristic, from detected interval, detect maximally related absolute altitude position.The image analysis of digital picture that so just can be by having used the river detects river level information.And, because monochrome information is to obtain average brightness value by each level line 10, so the long more monochrome information that can emphasize more by the lip-deep horizontal line direction of subject of level line 10 representatives of the observation width of horizontal direction, thereby can eliminate noise on the digital picture effectively.
Like this, because can obtain river level based on the monochrome information that obtains by digital picture, even so be difficult under the situation of reading images in difference (the particularly reduction of the illuminance at night) owing to meteorological condition, also become can be easily and precision obtain river level goodly.
In addition, attribute information owing to the latitude of each pixel of digital picture being paid subject 2, longitude, absolute altitude etc., so can carry out more high-precision image analysis by monitoring the more accurate geographic coordinate that obtains each pixel in the display screen picture picture displayed.
And, cover situation according to the ground in water-level observation place, the feature situation inequality of mean flow rate change curve is also arranged, can consider by adjusting the parameter of above-mentioned waveform, and the place when river level information is extracted in restriction especially.
The embodiment of other when then, adopting Fig. 8 to extraction river level information describes.In the present embodiment, have storage and change the monochrome information reservoir 33 (with reference to figure 5) that the data of monochrome information are measured on ground, distinguish in the portion 28 in rerum natura and distinguish river level based on the monochrome information that is stored in the monochrome information reservoir 33 through the time.
Particularly, the digital picture during from the moment (T1) and (T1+ Δ t), calculate the lip-deep mean flow rate change curve of subject (40a, 40b) respectively along the absolute altitude direction.Then, the monochrome information during based on moment (T1) of being stored in the monochrome information reservoir 33, and with reference to the corresponding local curve pattern of water level of (T1) constantly, extract the maximally related curve of shape interval from the curve of (T1+ Δ t) constantly.Can think that the absolute altitude position corresponding with the minimum value of mean flow rate in this extraction interval is the water level of (T1+ Δ t) constantly.Like this, measure river level, so, can carry out more high-precision measurement than the situation of measuring river level based on the data of input in advance based on the monochrome information that is stored in the past in the monochrome information storage element 33.
Figure 11 is the figure that is illustrated in the viewing window pictures that monitors the mean flow rate change curve that shows in the display screen picture.As shown in figure 11, on viewing window pictures, change ground and show the mean flow rate change curve, and show each parameter that is used for determining river level by the mean flow rate change curve in the lower portion of viewing window pictures through the time.In addition, the river level of utilizing rerum natura to distinguish that portion 28 calculates is presented on the curve map of mean flow rate change curve (being represented by E among Figure 11).
And, in the level measurement device 1 that the present invention relates to, also can be when the water level of measuring surpass predefined water level (for example, being represented by F among Figure 11) absolute altitude, the measurement frequency of flooding.
Like this, owing to become the measurement frequency that predefined absolute altitude improves river level when above measuring water level, so by obtaining water level information in real time, for example, can be suitably and promptly tackle by the discharge water adjustment etc. of caused river discharge of warning order of alarm and reservoir.
