Description
Technical field
The present invention relates to a kind of spectrum quantization definite value multi-spectral remote sensing images to divide sensor color collecting device, belongs to
Cartography and Geography Information System technical field.
Background technology
In daily life, people generally complete the acquisition of picture signal with digital camera or scanner.Scanner pair
The principle that image is acquired is：Original copy is put on a glass, starts driver, scanner light source is strip, and along Y
Direction is inswept entire original copy is irradiated to the light on original copy and passes through a very narrow gap after reflection, formed in X direction
Light belt, and pass through one group of reflective mirror, spectroscope is focused by optical lens and entered, is obtained by prism and redgreenblue filter
To tri- colour light bands of RGB be respectively radiated on respective CCD, rgb light band is transformed into analog electronic signal by CCD, this letter
Number digital electronic signal is transformed by A/D converters again.So far, the optical signal for reacting original image is transformed into computer and can connect
The binary digit electronic signal received, send finally by interfaces such as serial or parallels to computer.Scanner often sweeps a line must
To the image information of original copy X-direction a line, with moving along Y direction, the full figure of original copy is gradually formed in computer-internal.
During scanner obtains image, play a key effect there are two element, first, CCD (charge-coupled
Device, charge coupled cell, also referred to as ccd image sensor), it is a kind of semiconductor devices, it is the same to act like film, energy
It is enough that optical image signal is converted into analog electrical signal；The other is A/D converters, analog electrical signal conversion is known as number by it
Signal.During auto-focusing, the auto-focusing principle of slr camera, i.e. phase-detection focusing technology：Slr camera fuselage
Reflective mirror is made of two pieces of rear reflectors：Primary mirror and auxiliary mirror.Primary mirror centre is transparent, corresponds to auxiliary mirror.Primary mirror and auxiliary mirror
Lens imaging light is projected to frosted glass together, the phase-detection that auxiliary mirror can reflect a part of light arrival mirror cell bottom is automatic
Focusing module.There are two lenslet, the respective fraction captured in focus point region both sides image in module, it is divided into projecting
In two groups of CCD arrays.At sensitive chip rear, they exist the image that acquisition is arrived for the position of the two conceptive lenslets
It is focused in CCD arrays.If lens focusing is accurate, the two pictures focused again can be in respective CCD arrays center, between the two
Distance be focusing it is accurate when phase.If lens imaging position is in front of sensitive chip, the distance between upper two pictures of CCD ratio
Relatively closely, that is, phase bit comparison is short；Conversely, if lens imaging position is at the distance between sensitive chip rear, upper two pictures of CCD
It is distant, that is, phase is long.So from than the difference between calibrated burnt phase and non-accurate burnt phase, so that it may to calculate mirror
Camera lens, is once put into positioning by the direction moved and distance when head focusing, then mobile instruction is assigned to camera lens, to focus at
Work(.Have currently, multi-spectral remote sensing image segregation method is common：Edge detection method, this is that one kind dividing object by battery limit (BL) of critical value
With the straightforward procedure of background；Boundary method, this is that there are the methods on boundary between 2 regions for searching；Edge method recognizes the side of pixel
Boundary, and the method for finding out object boundary that they are linked together；Threshold value partitioning, this threshold value division in image segmentation are
It is also simply most a kind of the most useful dividing method, main idea is very direct, is a kind of division based on histogram.More than
All methods no matter visual analysis or quantitative accuracy evaluation all consistently illustrate, there is no best threshold values can make institute simultaneously
Some types of ground objects reach best segmentation result, have respective characteristic on different levels per class atural object.Therefore, more rulers
Degree segmentation more efficient can accurately reflect ground actual conditions.But how accurate evaluation multi-scale division and to efficiently use
The problem of multi-scale division result is still further research.Maximum likelihood classification (Maximum Likelihood
Classifier, MLC) it is based on Bayes (Bayes) criterion, it is considered to be the good grader of a kind of stability, robustness.It is maximum
Likelihood classification assumes that each wave band data is in normal distribution in remote sensing images.Basic thought is that ground species data are in space
Middle to constitute specific point group, every one-dimensional data of each classification is in normal distribution, the multidimensional of the category on the number axis of oneself
Data constitute a multiple normal distribution.The distribution characteristics that the multiple normal distribution model of each classification has its different, for example,
Shape, density, position and degree of scatter etc..For a tool there are three the normal distribution of feature, each classification is one
The bell cube of a approximation, " clock " of different classes of formation is all not quite similar height, thickness, point are wealthy etc., according to each
The given data of class can construct the frequency that multiple normal distribution model of all categories is actually data vector of all categories,
That is probability-distribution function or probability density function.On this basis, for any one pixel, it can be asked to belong to every in turn
The probability of a classification, it is classification results to take the corresponding classification of maximum probability.People's discernable by eye rate refers to that human eye can differentiate two
The ability of a adjacent point either line is usually with just can be by separated 2 points or two lines and subtended angle formed by eye pupil center
It indicates, the distance that minimum is differentiated is 0.2mm or so.Observe and analyze it is smaller apart from when, just must by specialized equipment,
For example light microscope, the limit of resolution are about that 200nm magnifying powers are 500-1000 times, the electron microscope limit of resolution is about
0.2nm magnifying powers are 200-200000 times, then through photograph amplification up to 1000000 times.Normal eye is about 555nm's to wavelength
Electromagnetic wave is most sensitive.The main natural source of visible light is the sun, and main artificial light source is incandescent object especially incandescent lamp,
The visible spectrum that they are emitted is continuous, and gas-discharge tube also emits visible light, and spectrum is separation, is often utilized various
Gas-discharge tube adds optical filter as monochromatic source.Development in science and technology is to today, and either scanner or digital camera can be compared with
Digital information is converted image information into well by computer identification, storage and output, but in image processing process, often
Once encountering enlarged drawing, the quality especially boundary of exported image becomes blurred, to find out its cause, being exactly aobvious in image
Using prism and RGB three-primary colours during showing, and it is not three colors in natural visible light, but seven colors：Red, orange, yellow,
Green, blue, indigo, purple, wavelength are respectively：Red 750nm-620nm, orange 620nm-590nm, Huang 590nm-570nm, green 570nm-
495nm, indigo plant 495nm-475nm, indigo 475nm-450nm, the light wave between purple 450nm-380nm, 380nm-10nm are ultraviolet light,
And the light between 750nm-1000000nm is infrared ray.That is from 380nm to 750nm, range is visible light, light entirely
Spectrum is a continuous wavelength, only RGB three-primary colours is used to express entire spectrum, some light will certainly be caused to be ignored, institute

Specific implementation mode
Embodiment one：
Spectrum quantifies definite value multi-spectral remote sensing image and divides sensor color collecting device, imitates maximum likelihood point first
Class method is divided into seven kinds of colors in usual people to visible light：Red, orange, yellow, green, blue, indigo, purple, wavelength are respectively：It is red
750nm-620nm, orange 620nm-590nm, Huang 590nm-570nm, green 570nm-495nm, indigo plant 495nm-475nm, indigo 475nm-
Light wave between 450nm, purple 450nm-380nm, 380nm-10nm is ultraviolet light, and the light between 750nm-1000000nm
On the basis of infrared ray, spectrum quantization definite value further will be seen that often 5nm is a color module, each color to light according to wavelength
There are one codes for module, then 74 color modules are shared from 380nm-750nm, using the first of each color English name
A letter is respectively labeled as V1-14, B1-5, C1-4, G1-15, Y1-4, O1-6, R1-26；And the spatial positional information of module is then
It is indicated with L (length), W (width) Y, A, X indicates that length, Y indicate that width, Z indicate height, in this manner it is possible to will obtain
Remote sensing images in the information each put come out with different symbolic indications.Secondly, using K- means clustering methods to specifically dividing
The image information for cutting out carries out clustering ensemble, and arbitrary remote sensing images are split quantization definite value to reach, each to put
One group of data can be corresponded to, is more prone to become the purpose for the signal that computer can identify on the basis of dividing identification.Generally
The specific segmentation standard of image selection of unit area, such as length and width are 1 meter image 5 nanometers of modules of selection, i.e., 5 receive
All color informations one group of specific numerical value of equal fixation mark in metric wave length, is stored with computer, and this requires calculate
Machine has 74 separations, and each to separate corresponding module, once the information of module appears on remote sensing images, computer will
It is stored in a manner of 0 or 1 in corresponding separate, can also be exported in a manner of 0 or 1 when transferring, ensure that image in this way
Original state, and be not in distortion；Afterwards in use, can also continue according to this principle point in the tool of higher precision
It cuts, in order to provide higher precision.It overcomes previous image segmentation and spiced salt phenomenon occurs so that image fidelity is simultaneously clear.Clearly
It completes to reach free conversion between beautiful scenery and number glibly.Seven-colour-light is combined as white light, is then black without light.
Maximum likelihood classification is using Gaussian probability-density function as probability density function.Sufficient sample data is to meter
It is highly important to calculate the mean vector of each classification and variance matrix.But it is one relatively reasonable to select how many data
Number？In theory, if a remote sensing images have m wave band, then the minimum training sample pixel number of each classification is m
+1.For actually, in order to accurately calculate the parameter of each classification, the pixel number of training sample should be higher than that 10 × m.
The probability density function of a certain particular category i has following form in single band,
In formula, P (X/ ωi) it is for vectorial X, the probability density function of classification i；μiIt is the mean value of classification i,σi 2It is the variance of classification i,N is the pixel number of training sample；xjIt is the instruction of classification i
Practice the value of j-th of pixel in sample set.
Probability density function can become complicated with increasing for image band number, at this moment can use a matrix to handle
Probability density function.For a m dimensional feature space, pixel value vector X, the mean vector U of each classificationiAnd covariance matrix
∑iWith following form,
In formula, the element value calculating in mean value and covariance matrix is as follows,
Then m ties up normalized probability density function and is,
Wherein, | ∑i| it is the matrix value of covariance matrix, ∑i -1It is the inverse matrix of covariance matrix, (X-Ui)TIt is vector
(X-Ui) transposed matrix.
When judging which classification some point belong to, maximum likelihood Bayesian decision method is utilized according to formula (6),
P(X/ωi)*P(ωi)≥P(X/ωj)*P(ωj) (6)
If formula (6) is set up, which should be attributed to class i, otherwise should be attributed to class j.However, in practical applications, prior probability P
(ωi) it is ignorant, usually take the prior probability of each classification equal, then formula (6) can be rewritten as,
P(X/ωi)≥P(X/ωj) (7)
Maximum likelihood classification is to obtain probability density function values by calculating the statistical value of sample.For unknown classification
The belonging kinds of pixel should be the classification for obtaining maximum probability density function values.Maximum likelihood classification in practical applications,
One of highest grader of nicety of grading.
The clustering ensemble that spectrum quantifies definite value multi-spectral remote sensing image segmentation sensor color collecting device is equal using K-
It is worth clustering method K-means, also known as C-means.K- means clustering methods are a kind of common clustering methods.Clustering criteria is to make
In each classification, the quadratic sum of pixel to the distance at category center is minimum.Basic thought is by iteration, and movement is each
The center of classification, until meeting the condition of convergence.The condition of convergence is to calculate the pixel value in such for any one classification
With the quadratic sum of such equal value difference.The quadratic sum of all differences is added, value after being added is made to reach minimum.
If total class number is m, mean value of all categories is Ci, the pixel in classification is Ni, pixel value fij, then the condition of convergence be
Formula (8) reaches minimum：
Specifically steps are as follows for calculating for K-means methods：
1st step suitably chooses the initial center Z of m classification1 (1), Z2 (1)..., Zm (1).The selection of initial center is to cluster
As a result it has a certain impact, generally there is following two methods：
1. according to problem property and empirically determined classification number m, from found out in data suitable m classification it is initial in
The heart；
2. all data are randomly divided into m classification, the center of gravity of each classification is calculated, using these centers of gravity as m classification
Initial center.
2nd step is adjusted to it in m classification any one sample X in kth time iteration as follows
In some classification.For all i ≠ j, i=1,2 ..., m, if | | X-Zj (k)| | < | | X-Zi (k)| |, then X ∈ Sj (k),
Wherein Sj (k)It is with Zj (k)Centered on class.
3rd step, the 2nd step obtain Sj (k)The new center Z of classj (k+1),Wherein, NjFor Sj (k)In class
Sample number.Zj (k+1)It is determined according to the principle of formula (9) error sum of squares J minimums.
4th step, for all i=1,2 ..., m, if Zj (k+1)=Zj (k), then iteration terminate, otherwise go to the 2nd step after
Continuous iteration.
