Embodiment
Describe the utility model in detail with embodiment with reference to the accompanying drawings below, it is more obvious that the purpose of this utility model and effect will become.
As shown in Figure 1, thin slice counter and technical method that the utility model is handled based on image comprise CCD camera 1, annular light source 2, electric displacement platform 3, display 4, base 5, anchor clamps 6, power supply 7, signal processing system 8, parts fixed mount 9, shell 10, mouse and keyboard (not shown).Shell 10 is fixed on the base 5, forms housing.CCD camera 1, annular light source 2, electric displacement platform 3, anchor clamps 6, power supply 7, signal processing system 8 and parts fixed mount 9 all place in this housing, and wherein, electric displacement platform 3, power supply 7, signal processing system 8 and parts fixed mount 9 all are fixed on the base 5.Anchor clamps 6 are fixed on the electric displacement platform 3, and CCD camera 1 and annular light source 2 are fixed on the parts fixed mount 9.CCD camera 1, annular light source 2, electric displacement platform 3, display 4, mouse and keyboard all link to each other with signal processing system 8, and power supply is CCD camera 1, annular light source 2, electric displacement platform 3 and signal processing system 8 power supplies.
The light emitting diode (LED) of annular light source 2 for evenly arranging in the utility model, light source are controlled the brightness of LED towards testee by adjusting current's intensity, at the outside translucent cover of installing of LED, make its irradiation light intensity even as far as possible.
Electric displacement platform 3 in the described counter is made up of step motor and platform that screw rod connects.Adjust the length of stepper motor steps according to the image size that arranges, make to overlap between the image of adjacent twice shooting.In addition, the interval of certain hour is arranged, the influence factors such as system's vibrations when eliminating photograph taking before each image taking.In addition, the calculating in the time of image splicing is for convenience installed the grayscale bar that obviously can distinguish on the both sides of electric displacement platform 3.Like this, we can be only just can judge coincidence position between the picture with the Pixel Information on the grayscale bar relatively, the synthesizing of realization image.
Signal processing system 8 in the described counter can be made of the common PC main frame.These parts are used for control CCD camera 1 and photo size, time shutter are set and take pictures, and control electric displacement platform 3 moves testee and the image that photographs is spliced and counts, and at last result of calculation is sent to display 4.As shown in Figure 3, picture splicing comprises and reads picture, chooses template, intersects steps such as comparative analysis, image be synthetic.The picture counting comprises steps such as gray processing processing, discrete Fourier transformation, spacing identification, gradient distribution processing, Boundary Recognition, calculating sheet number.
The course of work of the present utility model is as follows:
Step
1,System initialization: during system Installation and Debugging, the light intensity that can regulate the aperture size of CCD camera 1 bottom camera lens and annular light source 2 is set the brightness of pictures taken, finishes in case adjust, and can no longer do change in the later use.The time shutter of CCD camera 1 and the size of photo are set.In order to realize the splicing of picture, should guarantee that each picture shot size is constant.
Step
3,Image splicing: as shown in Figure 3, at first to the image pre-service and reduce pixel, choose the comparison template, adopt the cross correlation function maximal value to choose the method that overlaps the position, seamless spliced to there being two overlapping figure to carry out, by continued operation, can be with the synthetic width of cloth full picture of the image of several shootings.
As shown in Figure 3, need all images is handled one by one in the image splicing.At first there is overlapping image to be designated as A1, A2 the first, two two width of cloth, they are converted into gray-scale map by rgb format, and in order to reduce calculated amount, the Pixel Information of image is converted into new two width of cloth figure B1, B2 by the compression of lattice point equalization.Choose a 50*150 Pixel Dimensions as template from first width of cloth figure B1 left side, be designated as S (x, y), x wherein, y is horizontal ordinate and the ordinate of presentation video B1 respectively, S (x, value y) is the gray-scale value of this point; Second width of cloth figure B2 be designated as f (u, v), u wherein, v is horizontal ordinate and the ordinate of presentation video B2 respectively, (u, value v) is the gray-scale value of this point to f.Utilize cross-correlation technique to find the solution related function between two figure:
C (u, the more big presentation video of value v) is more similar, and (l when m) getting peak value, represents two figure B1, and B2 is in that (l, m) mate most the position in a certain position when related function.Known the coordinate of coupling, we just can determine the splicing coordinate of A1 and A2 two figure by the coordinate inverse transformation.By in first width of cloth figure A1 or second width of cloth figure A2, choosing not intersection another figure is spliced, obtain the composite diagram of two figure.Reuse this method, can be spliced into all pictures that CCD camera 1 photographs the image that one width of cloth finishes and be designated as G, comprehensively show the information of measured object.
At first image G is transferred to gray-scale map G (x, y), x wherein, y is horizontal ordinate and the ordinate of presentation video G respectively, and G (x, value y) is the gray-scale value of this point, choose the most obvious zone of signal power as analyzing data, this zone can be arranged in the middle of the image by system initialization.In order to eliminate the reflective strong and weak influence that causes because of sheet surface out-of-flatness in the process, obtain grey scale change information as far as possible accurately, we can choose a certain transverse area in processing procedure continuous 3-5 group is done the pixel equalization and is handled and become one group of pixel as a reference, and repeat this type of calculating at multizone, obtain many grey scale change curves, be designated as g
1(x), g
2(x), g
3(x) ... g
n(x).Each bar grey scale change curve all can be regarded the variation of gray-scale value on time domain as, and it is done discrete Fourier transformation, obtains the frequency domain figure of each bar grey scale curve:
In the formula, j=1 ~ n, n are natural number, and x is horizontal ordinate, and X represents that horizontal ordinate always counts,
Be sample frequency.In all frequency domain figures, search for g
j(
) maximal value, this maximal value institute respective frequencies
Inverse be the thin slice period T, just the every shared pixel of tested thin slice is T.Consider the existence of background information and error, can suppose that the shared pixel of thin slice is 0.8T ~ 1.3T.After knowing the roughly thickness of thin slice, each group gray-scale pixels curve is done the front and back difference handles, obtain the gradient map of every grey scale curve:
Wherein, a=T/2, x are the image lateral coordinates.Draw the frontier point of testee by the appearance position of comparing extreme point in gray-scale map and the gradient map.After trying to achieve the approximate spacing of measured object approximate region and thin slice, we need be to point-to-point analysis observation grey scale change in this zone.One of thickness setting according to thin slice is effectively judged spacing 0.8T ~ 1.3T, marks out minimal value and minimum value in the distance during this time.If have in this judgement spacing minimal value then the sheet number add up 1; If do not have minimal value in this judgement zone, then search minimum value, this interval has minimum value then counting to be added up 1, if no minimum value, then counting does not increase.Because the reflecting rate difference between thin slice and the gap, the judgement grey scale change can be distinguished replacing of thin slice and gap, thereby gets the number of slice.
