Description

House type design method and related device

Technical Field

The application relates to a computer technology, which is applied to the field of buildings, in particular to a house type design method and a related device.

Background

In the field of buildings, a building or indoor designer splices different sub-house type area modules by means of a computer, sets relevant parameters such as the area, the approximate shape and size, application labels and the like of the sub-house type areas to obtain a house type sketch (commonly called a bubble sketch), and modifies the house type sketch and draws elements such as walls, area inlets, windows and the like according to more specific requirements such as north-south permeability, reasonable room division, dry-wet separation, high area utilization rate and the like, so that a final house type sketch is designed. Designers often wish to draw inspiration from similar past cases or to consult similar databases to find a custom figure of reference value before drawing the custom figure.

How to efficiently recommend the required reference floor plan to the user is a technical problem that those skilled in the art are studying.

Disclosure of Invention

The embodiment of the application discloses a house type design method and a related device, which can recommend a house type graph similar to an initial house type graph to the initial house type graph drawn by a designer according to the initial house type graph, thereby improving the efficiency of drawing the house type graph by the designer.

In a first aspect, an embodiment of the present application provides a house type design method, where the method includes:

acquiring an initial house type graph, wherein the initial house type graph comprises a house type entrance, a plurality of sub house type areas and a plurality of sub house type area entrances;

determining a first topological relation and a second topological relation of the initial house type graph, wherein the first topological relation of the initial house type graph comprises first reference information of a plurality of sub house type areas in the initial house type graph relative to house type entrances in the initial house type graph respectively, the second topological relation of the initial house type graph comprises second reference information of the plurality of sub house type area entrances in the initial house type graph relative to the house type entrances in the initial house type graph respectively, the first reference information comprises one or more of distance, position and direction, and the second reference information comprises one or more of distance, position and direction;

matching a recommended house type graph similar to the initial house type graph from a house type library according to the first topological relation and the second topological relation of the initial house type graph, wherein the house type library comprises a plurality of house type graphs, and each house type graph in the plurality of house type graphs corresponds to the first topological relation and the second topological relation;

and outputting the recommended user pattern.

In the method, the topological relation can reflect the spatial structure relation among the graphic elements in the overall concept, wherein the first topological relation is used for reflecting the connectivity and the adjacency of a plurality of sub-house type areas in the house type diagram and can be described by using the first reference information, so that the similarity between the plurality of house type diagrams in the house type library and the initial house type diagram can be judged by using the first topological relation. The second topological relation is used for reflecting the relative positions of the entrances of the plurality of sub-house type areas in the house type graph and can be described by using second reference information, so that the similarity between the plurality of house type graphs in the house type library and the initial house type graph can be judged by using the second topological relation.

If two or more house type graphs exist in the house type library, the first topological relations of the two or more house type graphs are the same, but the second topological relations are different, or the second topological relations of the two or more house type graphs are the same, but the first topological relations are different, the similarity between the two or more house type graphs and the initial house type graph is difficult to distinguish by only using a single topological relation, so the method combines the first topological relation and the second topological relation for comprehensively judging the similarity between the multiple house type graphs in the house type library and the initial house type graph, the limitation of matching aiming at the single topological relation can be avoided, and the matching accuracy is improved.

It should be noted that the initial house type graph is a house type sketch drawn by a designer, and when the initial house type graph is continuously changed due to drawing of the designer, the output recommended house type graph is changed, so that the method can recommend the similar house type graph for the designer in real time in the drawing process of the designer, the designer can conveniently obtain design inspiration, and the efficiency of drawing the house type graph by the designer is improved.

With reference to the first aspect, in a possible implementation manner, the determining a first topological relation and a second topological relation of the initial user-type graph includes:

determining the position of a house type entrance in the initial house type graph, and determining first reference information of a plurality of sub house type areas in the initial house type graph relative to the house type entrance by taking the house type entrance as a reference;

and determining a second topological relation of the initial house type graph according to second reference information of a plurality of sub house type area entrances corresponding to the plurality of sub house type areas relative to the house type entrance respectively.

In the method, the element types of different house type graphs may be different, and the house type entries are indispensable elements in the house type graph, so that the house type entries are used as a reference to unify the reference elements of the initial house type graph and the plurality of house type graphs in the house type library, so that the plurality of sub-house type areas in the house type graph respectively determine the first reference information relative to the reference element, and the plurality of sub-house type area entries of the house type graph respectively determine the second reference information relative to the reference element, thereby unifying the content forms of the first topological relation and the second topological relation of the different house type graphs. The method is beneficial to matching the topological relation of the initial layout drawing with the topological relations of the layout drawings respectively.

With reference to the first aspect, or any one of the foregoing possible implementation manners of the first aspect, in another possible implementation manner, the first reference information of each of a plurality of sub-house type areas in the initial house type diagram with respect to a house type entrance in the initial house type diagram includes:

first reference information of center points of a plurality of sub-house type areas in the initial house type graph relative to a center point of a house type entrance in the initial house type graph;

the second reference information of the plurality of sub-house type area entrances in the initial house type graph respectively corresponding to the house type entrances in the initial house type graph comprises:

second reference information of center points of a plurality of sub-house type area inlets in the initial house type graph relative to the center point of the house type inlet in the initial house type graph.

The initial house type graph is simplified by the method, the house type inlets, the plurality of sub-house type areas and the plurality of sub-house type area inlets in the initial house type graph are simplified into corresponding central points, and the house type graph becomes a scatter diagram formed by a plurality of points, so that the calculation process needed for obtaining the first reference information in the first topological relation and the second reference information in the second topological relation of the initial house type graph is simplified.

It should be noted that, when the house type entrance, the plurality of sub-house type areas and the plurality of sub-house type area entrances are irregular patterns, the center point thereof is replaced with the center point of gravity thereof.

Optionally, the direction in the first reference information and the second reference information includes front, back, left, right, left front, left back, right front, or right back, or the direction includes east, south, west, north, southeast, northeast, southwest, or northwest.

It should be noted that, for convenience of calculation, different directions in the above method may correspond to different values.

Optionally, the distance between the first reference information and the second reference information includes a straight-line distance between two center points.

Optionally, the positions in the first reference information and the second reference information include a horizontal distance and a vertical distance between two central points; or the position in the first reference information and the second reference information includes an acute angle formed by a straight line obtained by connecting two central points and a preset reference line.

It should be noted that, considering that there may exist a house type graph completely symmetrical to the initial house type graph in the house type library, the above method does not select a mode of establishing a rectangular coordinate system or a polar coordinate system with the house type entrance center point of the initial house type graph as the origin, but a mode of combining horizontal/vertical distances between two center points or a mode of an acute angle formed by a straight line connecting two center points and a preset reference line, for describing the positions of the center points of the plurality of sub-house type areas and the center points of the plurality of sub-house type area entrances of the initial house type graph relative to the house type entrance center point, and avoids the occurrence of a situation that there exists a house type graph completely symmetrical to the initial house type graph in the house type library without recommendation.

With reference to the first aspect or any one of the foregoing possible implementation manners of the first aspect, in a further possible implementation manner, the matching, according to the first topological relation and the second topological relation of the initial house type graph, a recommended house type graph similar to the initial house type graph from a house type library includes:

determining the comprehensive similarity of each house type graph and the initial house type graph according to the first similarity and the second similarity of each house type graph and the initial house type graph;

and determining a recommended layout similar to the initial layout according to the comprehensive similarity.

In the method, the initial family pattern and the first similarity of each family pattern in the family library to the first topological relation and the second similarity of each family pattern to the first topological relation are comprehensively considered, and the family pattern similar to the initial family pattern can be comprehensively and accurately recommended to the designer by determining the comprehensive similarity.

With reference to the first aspect or any one of the foregoing possible implementation manners of the first aspect, in yet another possible implementation manner, the first topological relation of the initial user-type graph includes a matrix M with a dimension of n \1093m ₁ Wherein:

wherein n represents the number of a plurality of sub-house type areas in the initial house type graph, and m represents the number of data types in the first reference information; a is a _xy Representing the y type data in the first reference information of the x-th sub-house type area in the initial house type graph relative to the house type entrance in the initial house type graph, wherein n and m are positive integers which are more than 1, and x is equal to 1, 2, 3, \ 8230;, n-1, n, and y is equal to 1, 2, 3, \\ 8230;, m-1, m; the matrix A ₁ 、A ₂ 、…、A _n-1 、A _n Respectively said matrix M ₁ The row matrix is used for representing first reference information of an x-th sub-house type area in the initial house type graph relative to a house type entrance in the initial house type graph;

the second topological relation of the initial user type graph comprises a matrix M with the dimension p \1093q ₂ Wherein:

wherein p represents the number of a plurality of sub-house type area entries in the initial house type graph, and q represents the number of data types in the second reference information; b is _ij Representing jth type data in second reference information of an ith sub-house type area entrance in the initial house type graph relative to the house type entrance in the initial house type graph, wherein p and q are positive integers, i is equal to 1, 2, 3, \ 8230;, p-1, p, and j is equal to 1, 2, 3, \\ 8230;, q-1, q; the matrix B ₁ 、B ₂ 、…、B _p-1 、B _p Respectively being said matrix M ₂ A row matrix ofSecond reference information representing the i-th sub-subscriber zone entry in the initial subscriber graph relative to the subscriber entry in the initial subscriber graph.

In the method, different types of data of the first reference information in the first topological relation of the initial floor plan are collected into a matrix form, and the first reference information (such as one or more of distance, position and direction) of a plurality of sub-floor plan areas in the initial floor plan relative to a floor entrance in the initial floor plan can be clearly and intensively represented; similarly, the different types of data of the second reference information in the second topological relation of the initial user type graph are collected into a matrix form, and the second reference information (such as one or more items of distance, position and direction) of the plurality of sub user type area entrances in the initial user type graph relative to the user type entrances in the initial user type graph can be clearly and intensively represented.

Specifically, the first topological relation and the second topological relation of each house type graph in the house type library are also in the same matrix form, so that the subsequent calculation of the first similarity and the second similarity is facilitated.

With reference to the first aspect, or any one of the foregoing possible implementation manners of the first aspect, in yet another possible implementation manner, the comparing the first topological relation corresponding to each house type graph with the first topological relation of the initial house type graph to obtain a first similarity between each house type graph and the initial house type graph includes:

calculating cosine similarity between a matrix in the first topological relation of the initial house type graph and a matrix in the first topological relation of the first house type graph to obtain a first cosine matrix, wherein the first cosine matrix is used for representing the first similarity between each house type graph and the initial house type graph, and the first house type graph is any one of the house type graphs;

comparing the second topological relation corresponding to each house type graph with the second topological relation of the initial house type graph respectively to obtain a second similarity between each house type graph and the initial house type graph, including:

and calculating cosine similarity of a matrix in the second topological relation of the initial house type graph and a matrix in the second topological relation of the first house type graph to obtain a second cosine matrix, wherein the second cosine matrix is used for representing the second similarity of each house type graph and the initial house type graph.

The method quantifies the similarity of the initial house type graph and any house type graph in the house type library into cosine similarity calculation between two different matrixes. It should be noted that, the cosine similarity calculation method is not only simple and convenient in calculation and wide in application range, but also only requires that the number of column matrixes between two different matrixes is equal. In the above method, the number of sub-house type areas of any house type graph in the initial house type graph and the house type library may not be equal, but the number of data types of the first/second reference information is equal, so that the number of matrix row matrices in the first/second topological relation of the initial house type graph and the number of matrix row vectors in the first/second topological relation of the any house type graph may not be equal, but the number of column matrices is equal, and therefore the cosine similarity algorithm is adopted to conform to the usage scenario of calculating the first/second similarity between the any house type graph and the initial house type graph in the above method.

Specifically, each element in the first cosine matrix represents a similarity between a certain sub-house type area in the initial house type diagram and a certain sub-house type area in any one house type diagram corresponding to the first reference information; each element in the second cosine matrix represents the similarity of a certain sub-house type area inlet in the initial house type graph and a certain sub-house type area inlet in any one house type graph corresponding to the second reference information; the comprehensive similarity between any one of the house pattern and the initial house pattern comprises a total weighted value obtained by weighting and calculating the sum value of all elements in the first cosine matrix and the sum value of all elements in the second cosine matrix.

Therefore, the cosine matrix can reflect the partial similarity between a certain sub-house type area or sub-house type area entrance of any one house type graph and a certain sub-house type area or sub-house type area entrance of the initial house type graph, and can also reflect the overall similarity between any one house type graph and the initial house type graph, so that a recommended house type graph with higher similarity can be obtained based on the cosine matrix.

In addition, the method takes the first similarity of any one house type diagram and the initial house type diagram as the primary similarity, and takes the second similarity as the secondary similarity, that is, the contributions of the first similarity and the second similarity to the comprehensive similarity are different, so that the sum of all elements in the first cosine matrix and the sum of all elements in the second cosine matrix are weighted by using the weighting coefficient, the contribution degree of the first similarity and the second similarity to the comprehensive similarity can be reflected, and the comprehensive similarity can be calculated more accurately.

With reference to the first aspect, or any one of the foregoing possible implementation manners of the first aspect, in yet another possible implementation manner, the determining, according to the comprehensive similarity, a recommended user type graph similar to the initial user type graph includes:

if the difference value of the comprehensive similarity of the second house type graph and the third house type graph is higher than a first preset threshold value, taking the house type graph with the comprehensive similarity arranged at the top N positions in the plurality of house type graphs as a recommended house type graph, wherein the second house type graph and the third house type graph are any two house type graphs in the plurality of house type graphs, and N is a positive integer;

if the difference value of the comprehensive similarity of the second house type graph and the third house type graph is lower than a first preset threshold value, comparing the third topological relation of the initial house type graph with the third topological relation of the second house type graph and the third topological relation of the third house type graph respectively to obtain the third similarity of the initial house type graph with the second house type graph and the third similarity of the third house type graph respectively, wherein the third topological relation comprises a polygon obtained by connecting the central points of all sub house type areas in the house type graph;

sequencing the plurality of house type graphs according to the comprehensive similarity to obtain a first sequencing result;

adjusting the house type graphs with the third similarity smaller than a second threshold value in the second house type graph and the third house type graph to the last digit in the first sequencing result to obtain a second sequencing result;

and taking the house type graph with the top N bits in the second sorting result as a recommended house type graph.

Specifically, the third similarity between the second or third house type diagram and the initial house type diagram is the similarity between a polygon obtained by connecting the central points of all the sub-house type areas in the second or third house type diagram and a polygon obtained by connecting the central points of all the sub-house type areas in the initial house type diagram.

In the method, when the positions in the first reference information and the second reference information comprise a horizontal distance and a vertical distance between two central points; or, when the position in the first reference information and the second reference information includes an acute angle between a straight line connecting two center points and a preset reference line, there may be a special house type diagram in the house type library that is far from the initial house type diagram in terms of the spatial structure relationship between the graphic elements, but has a high comprehensive similarity, and then the special house type diagram may be selected as the recommended house type diagram. In order to avoid this, similarity check is further performed on the preliminarily obtained first ranking result, specifically, the second house type graph and the third house type graph with close comprehensive similarity in the first ranking result are compared again by using a polygon similarity algorithm, and the house type graphs which are dissimilar to the initial house type graph in the second house type graph and the third house type graph are filtered out, so that a second ranking result is obtained. Therefore, the second ranking result can more accurately reflect the situation that a plurality of house type graphs in the house type library are similar to the initial house type graph, and the matching accuracy is further improved.

With reference to the first aspect or any one of the foregoing possible implementation manners of the first aspect, in a further possible implementation manner, after the outputting the recommended user pattern diagram, the method further includes:

and outputting the specified custom-type graph.

In the method, after obtaining the recommended house type diagram, the designer can select the house type diagram conforming to the specified condition again from the recommended house type diagram by specifying the condition, such as specifying one or more of the number, area, orientation or type of the sub-house type area or the sub-house type area entrance, which is convenient for the designer to quickly and accurately obtain the house type diagram similar to the initial house type diagram and conforming to the design requirement by combining with the design requirement of the designer.

The initial house type diagram comprises a house type entrance, a plurality of sub house type areas and a plurality of sub house type area entrances, and is generated by a terminal device (such as the terminal device 101 shown in figure 1) in response to an operation instruction of a designer. There are many ways to operate the instruction, which are easy to understand, and two possible ways are listed as follows:

the first method is as follows: a designer places a user-type entrance area block and a plurality of sub-user-type area blocks on a sketch editing interface presented by a terminal device, as shown in fig. 3, fig. 3 is a scene schematic diagram of an operation interface provided in an embodiment of the present application. The designer can edit the attributes of the area block, such as the name, area, size, and the like of the area block, in the right attribute panel 302 by clicking the area block 301, modify the size of the area block in the small floating window 303 of the sketch editing interface, and directly drag a movable point on the area block to modify the shape of the area block. The terminal equipment captures related operations of the editing page in real time, single-line wall changing, overlapping space, gap processing, door and window generation and the like are carried out on a sketch formed by splicing a plurality of area blocks, an initial house type graph is generated by a background, and the initial house type graph is sent to house type design equipment.

Optionally, the designer may return to the sketch editing interface by clicking the continue editing icon 404 on the lower right side of the preview floating window, and further modify the sketch spliced by the plurality of area blocks. As a further alternative, the designer may make further modifications to the details of the initial user-type diagram by clicking on the application icon 405 on the lower right side of the preview pane to enter a detail editing interface.

The second method comprises the following steps: the designer draws the house type drawing through other building design software, such as common automatic Computer Aided Design (CAD), and imports the house type drawing file with the attribute in the format of other building design software into the terminal device. The terminal equipment can convert the house type graph file into an initial house type graph which is suitable for the format of an operating system of the terminal equipment, and sends the initial house type graph to the house type design equipment.

Correspondingly, the house type design device receives the initial house type graph sent by the terminal device. Of course, the house type designing apparatus may also obtain the initial house type diagram through other ways, such as downloading from a network, and the specific obtaining manner is not limited herein.

Step S202: the house type design device determines a first topological relation and a second topological relation of the initial house type graph.

The initial house type graph comprises a first topological relation and a second topological relation, the first topological relation and the second topological relation can reflect the spatial structure relation among graphic elements in an overall concept, and specifically, the first topological relation comprises first reference information of a plurality of sub house type areas in the initial house type graph relative to a house type entrance in the initial house type graph respectively; the second topological relation of the initial house type graph comprises second reference information of a plurality of sub house type area entrances in the initial house type graph relative to the house type entrances in the initial house type graph. The first reference information includes one or more of a distance, a position, and an orientation, and the second reference information includes one or more of a distance, a position, and an orientation.

Optionally, when the house type design device determines the first topological relation and the second topological relation of the initial house type graph, the position of the house type entrance of the initial house type graph may be determined, and the first reference information of each of the plurality of sub-house type areas in the initial house type graph relative to the house type entrance is determined based on the house type entrance; determining a first topological relation of the initial house type graph according to first reference information of the plurality of sub house type areas relative to the house type entrance respectively; determining second reference information of a plurality of sub-house type area entrances corresponding to a plurality of sub-house type areas in the initial house type graph respectively relative to the house type entrance by taking the house type entrance as a reference; and determining a second topological relation of the initial house type graph according to second reference information of the plurality of sub house type area entrances relative to the house type entrances respectively.

The house type design device may sequentially determine, based on the house type entry, first reference information of the plurality of sub-house type areas respectively corresponding to the house type entry and second reference information of the plurality of sub-house type area entries respectively corresponding to the house type entry according to a preset rule, where the preset rule may be clockwise/counterclockwise, or an order of increasing the areas of the plurality of sub-house type areas from large to small or from small to large.

Alternatively, for convenience of data processing, the house type design device may simplify the initial house type diagram, and simplify the house type entry, the plurality of sub-house type areas and the plurality of sub-house type area entries in the initial house type diagram to the corresponding central points, where the initial house type diagram becomes a scatter diagram composed of a plurality of points. It should be noted that, when the house type entrance, the plurality of sub-house type areas and the plurality of sub-house type area entrances are irregular patterns, the center point thereof is replaced by the center point thereof.

In this case, the first topological relation includes first reference information of center points of a plurality of sub-subscriber type areas in the initial subscriber type graph with respect to a center point of a subscriber type entry in the initial subscriber type graph, and the second topological relation includes second reference information of center points of a plurality of sub-subscriber type area entries in the initial subscriber type graph with respect to a center point of a subscriber type entry in the initial subscriber type graph.

Taking the initial house type diagram 403 in fig. 4 as an example, point a is the central point of the house type entry in the initial house type diagram, and points b-h are the central points of the sub-house type areas in the initial house type diagram, respectively. The house type design equipment takes a point a as a center, two mutually perpendicular reference lines are established, namely a south-north (back-front) direction reference line and an east-west (right-left) direction reference line, then a point b, a point c and a point d are all located on the northeast (front right) surface of the point a, and a point e, a point f, a point g and a point h are all located on the southeast (back right) surface of the point a. It should be noted that, for the convenience of calculation, the directions in the above method can be expressed as different values. The house type designing apparatus can store the corresponding relationship between the direction and the value in the first reference information, which is convenient for understanding, please refer to table 1, where table 1 is an optional corresponding relationship between the direction and the value in the first reference information:

Optionally, the positions in the first reference information and the second reference information include a horizontal distance and a vertical distance between two central points; or the position in the first reference information and the second reference information comprises an acute angle between a straight line obtained by connecting two central points and a preset reference line.

It should be noted that, considering that there may exist a house type graph completely symmetrical to the initial house type graph in the house type library, the above method does not select a way of establishing a rectangular coordinate system or a polar coordinate system with the house type entrance center point of the initial house type graph as the origin, but a way of combining horizontal/vertical distances between two center points, or a way of connecting an acute angle between a straight line obtained by connecting two center points and a preset reference line, for describing the positions of the center points of the plurality of sub-house type regions and the entrance center points of the plurality of sub-house type regions of the initial house type graph relative to the house type entrance center point.

Step S203: and the house type design equipment matches a recommended house type graph similar to the initial house type graph from the house type library according to the first topological relation and the second topological relation of the initial house type graph.

The house type design device comprises a house type library, and the house type library is used for storing a plurality of house type graphs and corresponding first topological relations and second topological relations. The house type design equipment compares a first topological relation corresponding to each house type graph in a plurality of house type graphs of a house type library with a first topological relation of the initial house type graph respectively to obtain a first similarity of each house type graph and the initial house type graph; comparing the second topological relation corresponding to each house type graph with the second topological relation of the initial house type graph respectively to obtain a second similarity of each house type graph and the initial house type graph; then, determining the comprehensive similarity of each house type graph and the initial house type graph according to the first similarity and the second similarity, wherein all the house type graphs in the house type library respectively correspond to one comprehensive similarity; and finally, determining a recommended layout graph similar to the initial layout graph according to the comprehensive similarity.

Optionally, the first topological relationship of the first house type graph in the house type library includes a matrix M with a dimension k \1093m ₃ Wherein:

the first house type graph is any house type graph in the house type library.

Wherein k represents the number of a plurality of sub-house type areas in the first house type graph, and m represents the number of data types in the first reference information; c. C _gy Representing the y type data in the first reference information of the g-th sub-house type area in the first house type graph relative to the house type entrance in the first house type graph, wherein k and m are positive integers which are more than 1, g is equal to 1, 2, 3, \8230, k-1, k, y is equal to 1, 2, 3, \8230, m-1 and m; matrix C ₁ 、C ₂ 、…、C _k-1 、C _k Respectively being said matrix M ₃ The row matrix is used for representing first reference information of the g-th sub-house type area in the first house type graph relative to the house type entrance in the first house type graph;

the first topological relation of the first house type graph in the house type library comprises a matrix M with the dimensionality h \ 1093q ₄ Wherein:

wherein h represents the number of a plurality of sub-house type region entries in the first house type graph, and q represents the number of data types in the second reference information; d is a radical of _sj The j-th type data in the second reference information of the s-th sub-house type area entrance relative to the house type entrance in the first house type graph is represented, h and q are positive integers, s is equal to 1, 2, 3, \8230, h-1, h, j is equal to 1, 2, 3, \8230, q-1 and q; matrix D ₁ 、D ₂ 、…、D _h-1 、D _h Are respectively a matrix M ₄ The row matrix is used for representing second reference information of the entrance of the s-th sub-subscriber type area in the first subscriber type graph relative to the entrance of the subscriber type in the first subscriber type graph.

In the matching process, the house type design equipment can calculate the similarity of the initial house type graph and each house type graph in the house type library for the first topological relation and the similarity for the second topological relation by using a similarity algorithm between matrixes. The similarity calculation method of the matrix comprises cosine similarity, euclidean similarity, pearson similarity, hamming similarity and the like, wherein the cosine similarity calculation method is simple and convenient to calculate and wide in application range. The cosine similarity calculation method is to regard the row matrixes of two matrixes as row vectors and respectively calculate the similarity between the row vector of one matrix and the row vector of the other matrix. The similarity between two vectors is measured by the cosine value of the included angle between the vectors, and the more the included angle degree is close to 0, the more the cosine value is close to 1, the more the two vectors are similar; the cosine values of a plurality of vector included angles are integrated into a cosine matrix form to represent the similarity between the two matrixes, and the greater the sum value of all elements in the cosine matrix is, the higher the similarity between the two matrixes is.

The comprehensive similarity of the first house type graph and the initial house type graph is a total weighted value obtained after weighted operation of the sum value of all elements in the first cosine matrix and the sum value of all elements in the second cosine matrix.

For example, the integrated similarity δ may be represented by the following formula:

In the embodiment of the present application, when there exists a house type graph in the house type library that is symmetric to a sub-house type area or an entrance of a sub-house type area of the initial house type graph, that is, there exists a house type graph that is not completely symmetric to the initial house type graph, although the comprehensive similarity of the special house type graph is high, it is far from the initial house type graph in terms of the spatial structure relationship between the graphic elements. Therefore, the house type design equipment compares the house type graphs with the approximate comprehensive similarity in the house type library again by utilizing the third similarity, can make up the defect of matching the house type by utilizing the comprehensive similarity only, and distinguishes the house type graph which is completely symmetrical to the initial house type graph and the house type graph which is partially symmetrical in the house type library, thereby further improving the matching accuracy.

For example, when the first reference information in the first topological relation of the initial house type graph includes horizontal distances and vertical distances between center points of a plurality of sub-house type areas in the initial house type graph and center points of house type entrances in the initial house type graph, and the second reference information in the second topological relation of the initial house type graph includes horizontal distances and vertical distances between center points of a plurality of sub-house type area entrances in the initial house type graph and center points of house type entrances in the initial house type graph, the house type design device determines a recommended house type graph similar to the initial house type graph according to the comprehensive similarity, two situations may occur:

the first condition is as follows: if the difference value between the comprehensive similarities of the second house type graph and the third house type graph is higher than the first preset threshold, the house type design device takes the house type graph with the comprehensive similarity arranged at the top N bits in the plurality of house type graphs of the house type library as the recommended house type graph, it should be noted that the second house type graph and the third house type graph are any two house type graphs in the plurality of house type graphs, and N is a positive integer.

Case two: if the difference value of the comprehensive similarity between the second house type diagram and the third house type diagram is lower than a first preset threshold, the house type design equipment compares the third topological relation of the initial house type diagram with the third topological relation of the second house type diagram and the third topological relation of the third house type diagram respectively to obtain the third similarity between the initial house type diagram and the second house type diagram and the third similarity of the third house type diagram respectively, and it should be noted that the third topological relation includes a polygon obtained by connecting the central points of all the sub-house type areas in the house type diagram; then, the house type graphs are sorted according to the comprehensive similarity to obtain a first sorting result; then, adjusting the house pattern graph of which the third similarity is smaller than a second preset threshold value in the second house pattern graph and the third house pattern graph to the last position in the first sequencing result to obtain a second sequencing result; and finally, taking the house type graph with the top N bits in the second sorting result as a recommended house type graph.

And performing similarity check on the preliminarily obtained first sequencing result, specifically comparing the second house type graph and the third house type graph with close comprehensive similarity in the first sequencing result by using a polygon similarity algorithm, and filtering out the house type graphs which are not similar to the initial house type graph in the second house type graph and the third house type graph so as to obtain a second sequencing result. Therefore, the second ranking result can more accurately reflect the situation that a plurality of house type graphs in the house type library are similar to the initial house type graph, and the matching accuracy is further improved.

Referring to fig. 6, fig. 6 is a scene schematic diagram for calculating comprehensive similarity of a user-type diagram according to an embodiment of the present application, which is used to further describe a second case.

In the initial floor plan 601, point t ₁ Is the center point, point t, of the house type entry in the initial house type diagram 601 ₂ -point t ₅ Is the center point of a plurality of sub-house type areas in the initial house type diagram 601; in the second floor plan 602, point k ₁ Is the center point of the house type entry in the second house type diagram 602, point k ₂ Point k ₅ Is the center point, point k, of the sub-house type areas in the second house type graph 602 ₂ Point k ₅ Are respectively the point t in the initial floor plan 601 ₂ -point t ₅ A symmetry point with respect to a north-south reference line, so that the first topological relation of the second house type graph 602 is the same as the first topological relation of the initial house type graph 601, and the corresponding matrixes of the second house type graph 602 and the initial house type graph 601 are the same; in the third house type diagram 603, point s ₁ Is the third houseCenter point of house type entrance in type diagram 603, point s ₂ -point s ₅ Is the center point, point s, of the sub-house type areas in the third house type diagram 603 ₂ And s ₄ Are respectively the point t in the initial floor plan 601 ₂ And point t ₄ Point of symmetry with respect to the north-south reference line, point s ₃ Point s ₅ Respectively with the point t in the initial floor plan 601 ₃ And point t ₅ The positions are the same, so the first topological relation of the third floor plan 603 is different from the first topological relation of the initial floor plan 601, but the corresponding matrixes of the third floor plan 603 and the initial floor plan 601 are the same.

It should be noted that, in the embodiment of the present application, the case that the first topological relationship between the two house graphs is the same includes a case that the two house graphs are completely symmetric.

Similarly, the second topological relation of the second floor plan 602 is the same as the second topological relation of the initial floor plan 601, and the corresponding matrixes of the second floor plan 602 and the initial floor plan 601 are the same; the second topological relation of the third house type graph 603 is different from the second topological relation of the initial house type graph 601, but the corresponding matrixes of the third house type graph 603 and the initial house type graph 601 are the same.

In the first ordering result of the embodiment of the present application, the second and

third house graphs

602 and 603 have the same and the highest comprehensive similarity with the initial house graph 601, respectively, and the comprehensive similarity difference is smaller than the first preset threshold, but the third house graph 603 is far from the initial house graph 601 in terms of the spatial structure relationship between the graphic elements. Therefore, the house type design apparatus needs to further distinguish the second house type graph 602 from the third house type graph 603, and eliminate the third house type graph 603 from the first sorting result, which can be specifically implemented as follows:

the house layout equipment will initiate the point t in the house layout 601 ₂ -point t ₅ The polygon obtained by clockwise connection is respectively connected with the point k in the second floor plan 602 ₂ Point k ₅ The polygon resulting from the clockwise connection and the point s in the third house view 603 ₂ -point s ₅ Comparing the polygons obtained by clockwise connection, and calculating the similarity between the polygonsAnd obtaining a third similarity, and then adjusting the third floor plan 603 with the third similarity smaller than a second preset threshold value to the last bit in the first sequencing result to obtain a second sequencing result. The house type design device takes the house type graph with the top N bits in the second sorting result as a recommended house type graph. In this way, since the third house pattern 603 is ranked last, the third house pattern 603 is not preferentially selected by the house type designing apparatus as a recommended house pattern, and thus the third house pattern 603 is eliminated.

Alternatively, the similarity algorithm for polygons may include an angle method, an area method, a point-line judgment method, or an arc length method.

Step 204: the house type design equipment outputs a recommended house type graph.

The house type design equipment sends a recommended house type graph similar to the initial house type graph to the terminal equipment, and the terminal equipment displays the thumbnail of the recommended house type graph in a floating window of the operation interface for a designer to select. The designer can view the detail drawing of one recommended user-type drawing by clicking the thumbnail of the user-type drawing and can further edit the detail drawing. It should be noted that, when the initial custom graph is continuously changed due to the drawing of the designer, the output recommended custom graph is also changed.

Optionally, the house type design device may further obtain a screening instruction, where the screening instruction is used to specify one or more of the number, area, orientation, or type of the sub-house type region or the sub-house type region entrance; matching a specified floor plan which accords with the screening instruction from the recommended floor plan according to the screening instruction; the output specifies a custom graph.

After the designer obtains the recommended user type diagram, the designer can set the screening conditions through a screening bar displayed on an operation interface of the terminal equipment; the house type design equipment receives a screening instruction sent by the terminal equipment, then further screens the recommended house type graph according to the content of the screening instruction, and finally sends a specified house type graph matched with the screening instruction in the recommended house type graph to the terminal equipment; the terminal device displays the thumbnail of the designated house type graph in a floating window of an operation interface for a designer to select. The designer can also view the detail drawing of the user-type drawing by clicking one of the thumbnails of the specified user-type drawing and can further edit the detail drawing.

In this embodiment of the present application, the steps S201 to S204 may also be executed by other devices, for example, all the steps are executed by a terminal device, or may also be executed by multiple devices in cooperation, for example, a house type designing device and a terminal device each execute a part of the steps, and for convenience of understanding, the following description will be given by taking the execution subjects in the steps S201 to S204 as the terminal device as an example:

step S201: the terminal equipment acquires an initial user pattern.

In the method, the terminal device can identify the drawing behavior of the designer in the operation interface displayed by the terminal device, so as to generate the initial user-type diagram, and can also directly read the user-type diagrams in other building software formats and convert the user-type diagrams into the initial user-type diagrams corresponding to the own operating system format.

Step S202: the terminal equipment determines a first topological relation and a second topological relation of the initial user type graph.

Step S203: and the terminal equipment matches a recommended house type graph similar to the initial house type graph from the house type library according to the first topological relation and the second topological relation of the initial house type graph.

In the method, the terminal equipment comprises a house type library which is used for storing various house type graphs and corresponding first topological relations and second topological relations.

Step S204: and the terminal equipment outputs the recommended user pattern diagram.

In the method, the terminal equipment displays the recommended user-type diagram in an operation interface displayed by the terminal equipment so as to be selected and checked by designers.

According to the embodiment of the application, the house type design equipment can recommend a recommended house type graph similar to the initial house type graph to a designer in real time when the designer draws the initial house type graph, and the matching accuracy is improved by calculating the similarity of the topological relation between a plurality of house type graphs in a house type library of the house type design equipment and the initial house type graph, so that the design inspiration of the designer is stimulated, and the efficiency of drawing the house type graph by the designer is improved.
