As shown in Figure 1, the present invention provides a kind of methods based on high-definition remote sensing screening dangerous material stockyard, including such as
Lower step:
Step S100, textural characteristics are based on and obtain target area, different textural characteristics are distinguished by gray level co-occurrence matrixes
And architectural characteristic, and target area is extracted according to the uniformity coefficient of gray scale.
Step S101, setting L indicates the gray level of image local area, then gray level co-occurrence matrixes are expressed as in the region
The matrix of LxL,
That is Pθ, d=[PI, j]LxL, wherein matrix element PijIt is θ to be expressed as direction in image local area, and distance is d, gray scale

Co-occurrence matrix feature is extracted by statistical measurement by the frequency of appearance, obtains the grey scale change and line in the region
Manage feature.For example, if intensity profile is uneven in region, the value of the main focusing element of matrix can be bigger.
In the present embodiment, it is also necessary to attention, due in the processing procedure of gray level co-occurrence matrixes, the ash in region
Degree is random distribution, and similar frequency will be presented in the element in co-occurrence matrix, and this frequency will in high-definition picture
Will produce it is serious obscure interference, need to carry out fine processing, be convenient for identification and utilization of the subsequent step to textural characteristics, logical
It is finely extracted, is had by Gabor filtering progress textural characteristics after crossing gray level co-occurrence matrixes extraction spatial frequency and location information
The method of body is:
Step S101, set the functional form of Gabor filter as Wherein x, y are position coordinates, and j is space domain characteristic value, and w is concussion frequency, σxAnd σyRespectively
Standard deviation of the expression filter in the directions x and the directions y;
Step S102, scale parameter u and directioin parameter v is added, then filter function is:
guv(x, y)=a-uG (x ', y '), wherein u, v are integer, a > 1,
And derivative
DerivativeWherein K is total direction number;
Step S103, by filter function input image I (x, y) carry out m scale, the Gabor transformation in n direction,
And it is averaged to obtain m textural characteristics subband to the feature of unified scale different directions to get the characteristic vector work tieed up to a m
For the texture feature information X={ x of each pixel (x, y) in image1, x2..., xm}。
Step S200, feature point extraction is carried out by the method for scale-space, by scale parameter in target area
Convolution, which is carried out, with directioin parameter responds the invariant features of extraction image local maximum and minimum point as image as interest
Point.
The extraction of feature based point is due to detecting characteristic point in the target area, having operational efficiency high, extract feature
The advantages that abundant, convenient for the application in high-resolution remote sensing image.
In step s 200, the specific algorithm of scale-space method is:
Step S201, set the standard deviation Gauss equation of corresponding different scale as L (u, v, σ)=G (u, v, σ) * I (u,

It spends σ and is equal to parameter value, and the reference value of scale σ is 1.6.
Step S300, the space error that invariant features point is eliminated by translation vector is carried out by Hausdorff distances
The matching of model and image, and translation transformation is carried out by invariant features point and eliminates space error, invariant features point is intended
Close matching.
The Hausdor distances are specifically defined as:Set two remote sensing features point A={ a1, a2..., apAnd B=
{b1, b2..., bq, then Hausdor distances are H (A, B)=max (h (A, B), h (B, A)), wherein| | | | it is distance measure.
By above-mentioned definition it is found that Hausdor distances have weighed the whole matching degree of point set A and point set B, it is not suitable for
Therefore the subset of the subset and point set B of point set A when carrying out Hausdor distance calculating, that is, is carrying out scale-sky
Between method calculating when, two-way calculating should be carried out, using two-way Hausdor distances overcome subset cannot participate in calculate lack
It falls into, realizes comprehensive covering, the consistency matching of subset can be realized while point set is matched.
And among the above, the matching of model and image is carried out using the Hausdor distances of two-way part, this is the spy by image
What point determined, because image generally comprises multiple targets, and target in the picture is there may be the shielded situation in part, into
The two-way calculating of row can carry out the feature points of matched image section and model part by being arranged, and then overcome respectively
The above problem.
In step S300, invariant features point carry out translation transformation the specific steps are:
Step S301, two feature point set A={ a are set1, a2..., apAnd B={ b1, b2..., bq, and take characteristic point
Collect the reference set as range conversion;
Step S302, it setsIt is characterized the distance map of point set A, sets D 'It is characterized the distance map of point set B, then there are asked relative to each other when translation transformation between A and B
Take Hausdor distances;
Step S303, the ratio of the ratio of defined feature point set A and feature point set B or feature point set B and feature point set A
To convert threshold value, and sets the distances of the opposite Hausdor between A and B and make during carrying out translation transformation for F (x, y)
It is effective translation transformation to obtain the change threshold that F (x, y) is minimized to be less than 1.
During carrying out translation transformation, by above-mentioned it is found that not all above-mentioned transformation is meaningful,
Therefore it can be calculated in the range that translation collects very limited by acceleration strategy.
Step S400, invariant features point library is established, remote sensing features point is screened one by one, will be fitted matched inconvenient special
Sequence forms invariant features point library to sign point successively, and passes sequentially through contrast characteristic's point and screen, and obtains dangerous material stockyard.
After composition invariant features point library, specific screening step is as follows:
Step S401, setting time coefficient is γ1, cloud amount coefficient is γ2, resolution rate coefficient is γ3, wherein 0≤γ≤
1, and γ1+γ2+γ3=1;
Step S402, the weighted value of remote sensing image is γ=γ1xλ1+γ2xλ2+γ3xλ3, wherein λ1、λ2And λ3Respectively
The weight of coefficient of correspondence;
Step S403, the weighted value of the record per data is calculated according to the weighted value of above-mentioned remote sensing image, and to all
Remotely-sensed data is screened, and the maximum data of weighted value are charged to filter record collection.
In above-mentioned screening step, it is necessary first to according to the condition of retrieval, such as resolving range, geographic area and
Time range etc. retrieves satisfactory all remote sensing image data record sets, and weight system is determined further according to actual demand
Number carries out above-mentioned steps.
Duplicate removal processing is carried out to the filter record collection of acquisition, obtains new result set, retrieve and judges that filter record is concentrated
Data whether in result set, there is no result set is then added, until completing the retrieval of all data.
In conclusion the main characteristic of the invention lies in that:
(1) substantive characteristics of remote sensing images is utilized, image can be overcome to change the shadow brought in imaging process conditional
It rings, the application of correcting algorithm can be overcome, evaded the operation of correction, can also have been generated while having evaded correction calculation
Effect, reliable matching result;
