Description

Technical Field

[0001] The present invention belongs to the technical field of applied geophysics, and more specifically, relates to a method for randomly filling mineral particles, an electronic device, a storage medium, and a device. Background Art

[0002] In geological mapping and other engineering drawing software, it is usually necessary to fill different colors or different shapes of particulate matter to represent different information such as minerals, rocks, and strata. However, in all current software, most can only draw the same color or regular patterns in a closed area. Even if there is a random pattern filling scheme, due to limited parameters, only single-factor control can be performed, and the filling particles and sizes are limited.

[0003] In addition, in the research of disciplines such as material mechanics and seismic wave fields, it is also necessary to design models with various filling patterns to carry out finite element numerical research and analyze their mechanical properties or seismic wave field response characteristics. However, there is no random particle filling method constrained by scale distribution.

[0004] The information disclosed in the background art part of the present invention is only intended to deepen the understanding of the general background art of the present invention, and should not be regarded as an admission or any form of suggestion that this information constitutes the prior art known to those skilled in the art.

[0054] The present invention will be described in more detail below with reference to the accompanying drawings. Although the preferred embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0055] As shown Figure 1 in the figure, a method for randomly packing mineral particles according to the present invention includes:

[0056] Establish a size distribution trend chart of mineral particles, and the marked value of each coordinate point on the distribution trend chart represents the size of the mineral particles corresponding to the position of the coordinate point;

[0057] Establish a standard filling graphic database, and the standard filling graphic database stores an array of boundary point coordinates of different contour styles, and each array corresponds to a standard filling graphic;

[0058] Determine the filling quantity of mineral particles, and randomly generate a filling coordinate of a mineral particle;

[0059] Randomly determine the filling graphic of the mineral particle based on the graphic database;

[0060] Determine the magnification factor of the standard filling graphic based on the filling coordinate and the array corresponding to the standard filling graphic, and determine the size of the filling graphic based on the magnification factor;

[0061] Randomly determine the filling angle of the filling graphic, and determine the rotation angle of the filling graphic based on the filling angle;

[0062] Based on the filling coordinate, the coordinate values of adjacent coordinate points, and the marked value, determine whether the filling graphic overlaps with the filling graphics of adjacent coordinate points. If there is an overlap, delete the filling coordinate and randomly generate a filling coordinate of a mineral particle again;

[0063] If there is no overlap, fill the mineral particles into the mineral particle simulation model based on the filling coordinate, the size of the filling graphic, and the filling angle;

[0064] Repeat the filling until all mineral particles are filled.

[0065] Specifically, the present invention takes the trend of rock mineral particle scale as a constraint to control the random filling of rock mineral particles. First, a distribution trend diagram of mineral particle scale is established. The coordinate range of this distribution diagram is consistent with the range. The marked value at each coordinate point on this distribution diagram represents the size of the filling pattern of the filling particles at this position. This trend diagram can be provided by actual measurement or by a mathematical formula, and is in the form of a two-dimensional plane matrix, represented by Z(X,Y), where (X,Y) is the coordinate position of the matrix, and Z represents the size of the filling pattern of the mineral particles at this coordinate point. For example, 30(1,2) represents that the scale of the mineral particles at the coordinate point (1,2) is 30mm; then a standard filling pattern database is established. The standard filling pattern database stores the boundary point coordinate arrays of different contour styles, and each array corresponds to a standard filling pattern; the array coordinate range is between -1 and 1, as the standard size, that is, (x,y) ∈ [-1,1]. It can be considered that the particle center is at the position of (0,0). The number of inflection points of the boundary coordinates of the filling pattern of each particle is not limited. This graphic library can increase or decrease the standard filling patterns as needed; determine the filling quantity of the mineral particles, and randomly generate a filling coordinate of a mineral particle, the coordinate point (X,Y), and the coordinate point range is consistent with the coordinate of the particle scale size distribution trend diagram; read the coordinate array of this particle shape from the standard particle graphic library. This array is in the form of an m×2 matrix, that is, [x i ,y i , i ∈ [1,m], [x i ,y i represents the i-th inflection point coordinate of the polyline of the particle contour, and m is the number of inflection points; determine the size of the mineral particles based on the filling coordinate and the mineral particle scale distribution trend diagram. Read the scale information Z of the point (X,Y) from the particle scale size distribution trend diagram. The Z value reflects the particle scale size range at this point, and can also be understood as the magnification factor of the standard particle graphic library. Determine the magnification factor of the standard filling pattern based on the size of the mineral particles and the size of the standard mineral particles. Magnify the filling pattern based on the magnification factor, and the obtained particle boundary contour size is magnified by Z times, that is, the array Z×[x i ,y i = [Zx i ,Zy i ; randomly determine the filling angle of the filling pattern, and determine the rotation angle of the filling pattern based on the filling angle. The filling angle is θ, θ ∈ [0,2π]. Rotate the particle boundary contour coordinates [Zx i ,Zy i through the following expression to obtain the transformed coordinates [u i ,v i , Based on the coordinate values and marking values of the filling coordinate and adjacent coordinate points, determine whether the filling pattern of the filling coordinate overlaps with the filling patterns of adjacent coordinate points. That is, calculate the shortest distance between the two coordinate points according to the coordinate values of the filling coordinate and the adjacent coordinate points, and then determine whether the filling patterns corresponding to the two coordinate points overlap according to the marking values of the two coordinate points. For example, the filling coordinate is (1, 2), its corresponding marking value is 2, an adjacent coordinate point is (1, 5), and its corresponding marking value is 2. Then the shortest distance between the two coordinate points is 3. The filling pattern is centered on the filling coordinate. Assuming the filling pattern is a circle, the radius of the filling pattern is 1, and the radius of the filling pattern of the other coordinate point is also 1. 1 + 1 = 2 < 3, so the filling patterns of the filling coordinate and the adjacent coordinate point do not overlap; if they overlap, delete the filling coordinate and randomly generate a filling coordinate of a mineral particle again. If they do not overlap, fill the mineral particle into the mineral particle simulation model based on the filling coordinate, the size and filling angle of the filling pattern. Taking the point (X, Y) as the center point, draw the rotated particle contour as above, that is, with the coordinates [X + u i , Y + v i , i ∈ [1, m] as endpoints, draw a closed polyline and fill it with color, and repeat the filling until all the mineral particles are filled; the present invention performs mineral particle filling with the scale trend of rock mineral particles as a constraint, and can achieve a random filling effect with controllable scale distribution and shape.

[0066] In one example, the coordinate range of the array is between -1 and 1 as the standard filling pattern.

[0067] In one example, the generation range of the filling coordinate is the coordinate range of the mineral particle scale distribution trend diagram.

[0068] In one example, it further includes:

[0069] Specify the filling pattern of the mineral particle based on the graphic database.

[0070] Specifically, in addition to randomly determining the filling pattern of the mineral particle from the graphic database, the present invention can also artificially specify the filling pattern of the mineral particle.

[0071] In one example, the array is represented in the form of an m×2 matrix, that is, [x i , y i , i ∈ [1, m];

[0072] Where [x i , y i represents the i-th inflection point coordinate of the polyline of the particle outer contour, and m is the number of inflection points.

[0073] In one example, determining the rotation angle of the filling pattern based on the filling angle includes:

[0074]

[0075] where θ is the rotation angle of the filled pattern, [Zx i , Zy i are the coordinates of the boundary contour of the filled pattern, Z is the magnification factor of the standard filled pattern, [u i , v i are the coordinates of the filled pattern after rotating by θ in [Zx i , Zy i .

[0076] In one example, filling mineral particles into the mineral particle size distribution trend diagram based on the filling coordinates and the rotated filled pattern includes:

[0077] Taking the filling coordinates as the center, draw the rotated filled pattern in the mineral particle size distribution trend diagram based on the size and filling angle of the filled pattern.

[0078] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but it is not intended to limit the present invention. It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other.

[0079] Embodiment 1

[0080] This embodiment provides a method for randomly filling mineral particles, including:

[0081] Establish a mineral particle size distribution trend diagram, and the marked value of each coordinate point on the distribution trend diagram represents the size of the mineral particle corresponding to the coordinate point position; establish a standard filled pattern database, and the standard filled pattern database stores the boundary point coordinate arrays of different outer contour styles, and each array corresponds to a standard filled pattern, and the coordinate range of the array is between -1 and 1 to be used as the standard filled pattern, and the array is represented in the form of an m×2 matrix, that is, [x i , y i , i ∈ [1, m]; where [x i , y i represents the i-th inflection point coordinate of the polyline of the particle outer contour, and m is the number of inflection points; determine the filling quantity of the mineral particles, and randomly generate a filling coordinate of a mineral particle, and the generation range of the filling coordinate is the coordinate range of the mineral particle size distribution trend diagram; randomly determine the filling pattern of the mineral particle based on the graphic database, or specify the filling pattern of the mineral particle based on the graphic database; determine the magnification factor of the standard filled pattern based on the filling coordinate and the size of the standard filled pattern, and determine the filled pattern based on the magnification factor; randomly determine the filling angle of the filled pattern, determine the rotation angle of the filled pattern based on the filling angle, and perform rotation according to the following formula:

[0082] where θ is the rotation angle of the filled mineral particles, [Zx i , Zy i are the coordinates of the boundary contour of the filled pattern, Z is the magnification factor of the standard filled pattern, [u i , v i are the coordinates of the filled pattern after rotating by θ in [Zx i , Zy i ; determine whether the filled pattern at the filled coordinates overlaps with the filled patterns at adjacent coordinate points based on the coordinate values and coordinate numerical values of the filled coordinates and adjacent coordinate points. If there is an overlap, delete the filled coordinates and randomly generate a new filled coordinate for a mineral particle. If there is no overlap, fill the mineral particle into the mineral particle simulation model based on the filled coordinates, the size of the filled pattern, and the filling angle. With the filled coordinates as the center, draw the rotated filled pattern on the mineral particle scale distribution trend diagram based on the size and filling angle of the filled pattern; repeat the filling until all mineral particles are filled.

[0083] Example 2

[0084] As Figure 2 shown, this example provides a method for randomly filling mineral particles, including:

[0085] In the first step, first establish a scale size distribution trend diagram, and the coordinate range of this distribution diagram is the same as the range. The value corresponding to each coordinate point position on this distribution diagram represents the size of the filling particle pattern at this position. This trend diagram can be provided through actual measurement or through a mathematical formula, and is in the form of a two-dimensional plane matrix, represented by Z(X,Y), where (X,Y) is the coordinate position of the matrix, and Z represents the size of the filling particle at this coordinate point.

[0086] In the second step, establish a graphic database of standard particle shapes. This database stores the boundary point coordinate arrays of different contour styles, and the coordinate range is between -1 and 1, as the standard size, that is, (x,y) ∈ [-1,1], and it can be considered that the particle center is at the position (0,0). The number of inflection points of each particle boundary coordinate is not limited. This graphic library can be increased or decreased as needed.

[0087] In the third step, determine the number of particles N, and randomly generate a coordinate point (X,Y), and the coordinate point range is the same as the coordinates of the particle scale size distribution trend diagram, and set the particle number counter to 1, that is, assign the initial value j = 1.

[0088] In the fourth step, randomly or determine the shape of the particle, and read the coordinate array of this particle shape from the standard particle graphic library. This array is in the form of an m×2 matrix, that is, [x i , y i , i ∈ [1, m], [x i,y i represents the coordinates of the i-th inflection point of the polyline of the particle outer contour, and m is the number of inflection points.

[0089] In the fifth step, read the scale information Z of the point (X, Y) from the particle size distribution trend graph. The value of Z reflects the particle size range at this point and can also be understood as the magnification factor of the standard particle shape library.

[0090] In the sixth step, magnify the obtained particle boundary contour size by Z times, that is, the array Z×[x i ,y i = [Zx i ,Zy i .

[0091] In the seventh step, generate a random angle θ, θ∈[0, 2π], and use the following formula to rotate the particle boundary contour coordinates [Zx i ,Zy i to obtain the transformed coordinates [u i ,v i ;

[0092]

[0093] In the eighth step, with the point (X, Y) as the center point, draw the above-mentioned rotated particle contour, that is, draw a closed polyline with the coordinates [X + u i , Y + v i , i∈[1, m] as the endpoints and fill the color.

[0094] In the ninth step, calculate the distance between the center of the particle at (X, Y) and the adjacent particle center, and judge whether there is an overlap according to the sizes of the two particles. If there is an overlap between the two particles, execute the third step above; otherwise, execute the following tenth step; when j = 1 (only one particle), skip this step and execute the tenth step.

[0095] In the tenth step, increment the counter by 1, that is, j = j + 1;

[0096] In the eleventh step, judge the size of j and N: when j < N, execute the third step above; when j ≥ N, the process ends.

[0097] The following uses the random filling method of mineral particles in this embodiment for filling.

[0098] The scale distribution trend graph of the first mineral particle is as Figure 3 shown. The particle size on the left side of this graph is about 30 mm, and the particle size on the right side is 2 mm. The particle size distribution in the graph shows a linear decreasing law from left to right. Among them, the set number is 2000. When using fixed triangular particles for filling, the result is as Figure 4 shown; when using fixed circular particles, the result is asFigure 5 As shown; when adopting random non-fixed particle shapes, the results are as Figure 6 shown. In this random particle design, 7 particle shape styles are designed, and the particle shapes are randomly selected for each point. Of course, the particle shape graphics library can be increased, decreased, and designed according to needs.

[0099] Figure 7 is the second mineral particle size distribution trend graph, obtained by calculating with the following formula;

[0100] Z(x,y) = 30 * abs(sin(4πx / m) + cos(6πy / n))

[0101] Figure 7 The medium scale size is distributed in a periodic pattern. Similarly, for 2000 filling styles, when adopting fixed triangular particles, the effect is as Figure 8 shown; when adopting fixed circular particles, the effect is as Figure 9 shown; when adopting random non-fixed particle shapes, the effect is as Figure 10 shown (using the same 7-particle shape graphics library as above).
