Technical Field

Background

In modular building systems, facade design is particularly important, not only shaping the appearance of the building, but also having a direct impact on the synergistic efficiency of component manufacturing and installation. Therefore, how to improve the facade generation efficiency on the basis of ensuring the design rationality becomes an important problem to be solved in the building field.

In the prior art, modular facades are typically constructed from a plurality of geometrical units spliced together. In performing facade planning and combining, a plurality of factors such as building orientation, coplanar relation, size and space arrangement among units and the like are required to be integrated.

S10, responding to the building elevation generating instruction, and receiving an input integral building block model.

In this embodiment, the building facade generation instruction may be triggered automatically upon detection of a model upload to a designated interface or platform.

In this embodiment, the integral building block model includes a room module unit and a balcony module unit, which are distinguished according to a layer or a logo.

For example, the integral building block model can be a building model with high modularization application degree such as centralized residence, hotel and the like. Please refer to fig. 2, which is a schematic diagram of the overall building block model of the present invention. The overall building block model in the figure may comprise a plurality of room module units representing rooms (middle part) and a plurality of balcony module units (side parts).

The room module units and the balcony module units can be distinguished in a layered manner, and can be distinguished in other reasonable manners, such as by giving specific identification codes to different module units, so as to more clearly manage and identify different types of module units, and provide convenience for subsequent processes.

S11, identifying the elevation information of the integral building block model.

In this embodiment, the identifying facade information of the integral building block model includes:

recording the coplanarity between all the outer side surfaces;

For example, please refer to fig. 3, which is a schematic view of the outer side of the wall, the inner side of the balcony, and the outer side of the balcony according to the present invention. Fig. 3 shows a room module 1, a wall surface 11, a balcony module 2, a balcony inner side 21 and a balcony outer side 22. When the balcony module unit 2 is not present outside the room module unit 1, the outer side 11 of the wall surface is displayed.

Wherein the non-vertical surfaces are the top surface and the bottom surface.

Wherein, the coplanarity between all the outer sides can be recorded by a two-dimensional array. Specifically, each row of the array represents an outer side surface, the first row records the serial number of the surface, and the second row records the serial numbers of the other surfaces coplanar therewith, so as to clearly record the coplanar relationship.

And (3) determining the outer side surfaces with the included angles smaller than a certain threshold (such as 15 degrees) as having the same orientation by calculating the included angles of the two vectors.

And calculating the coincidence relation between the central point of each surface of the balcony module unit and all the outer side surfaces, namely calculating the inclusion relation of the points and the surfaces. Specifically, the coordinates of the point may be substituted into the plane equation, and if the plane equation is satisfied, the point is on the face.

Through the embodiment, the elevation information can be identified, and a basis is provided for subsequent processing.

And S12, carrying out elevation combination processing on the integral building block model according to the elevation information to obtain elevation combination information.

In this embodiment, the performing, according to the elevation information, the elevation combination processing on the integral building block model, where obtaining the elevation combination information includes:

Carrying out elevation layering treatment on the integral building block model according to the coordinate range and the elevation threshold value to obtain a plurality of layers, wherein when the coordinate range of the elevation model in the vertical direction is 0 to 30 meters, for example, the elevation can be divided into 10 layers by taking the elevation threshold value of 3 meters as one layer;

For example, for a rectangular elevation, the coordinates of the central points are ((x 1 + x 2)/2, (y 1 + y 2)/2), wherein (x 1, y 1) and (x 2, y 2) are the coordinates of diagonal vertices of the rectangle respectively, and further, the central points in the same layer are fitted into the straight line segments by using a least square method, namely, the best function matching of data is found by minimizing the square sum of errors, so that the straight line segments which can most represent the distribution trend of the central points are obtained;

For example, starting from the starting point of fitting a straight line segment, sequentially taking each central point as a dividing point, dividing the straight line segment into a plurality of sub-line segments, wherein the vertical surfaces corresponding to the two end points of each sub-line segment are a group of adjacent vertical surface combinations, so as to obtain the geometric representation of the paired vertical surface combinations;

In the processing process, layering is carried out on the graph, each layer is processed in a circulating mode, the vertical face combination condition of each face is obtained, and the vertical faces which do not participate in combination are classified as independent vertical face types. In the loop processing, a loop structure (such as for loop) in a programming language can be used, and from the first layer, the vertical face combination of each layer is processed in turn, and the combination result of each layer is stored in a list data structure, so that the subsequent unified analysis and processing are facilitated.

The curve feature extraction is performed according to the center point of each rectangular elevation, and the obtaining of the elevation curve feature comprises the following steps:

For example, the curve extraction is performed in a single direction (from left to right or from right to left), one is extracted at a time, and the curve extraction is performed according to a rule that each center point can only be selected once, that is, the starting and ending point of the former curve cannot be covered by the latter curve, so that the curve characteristics in the graph are extracted in this way. In the extraction process, if the point coincidence occurs, the corresponding group is not selected. In the actual extraction, a list can be used to record the already selected center points, and before each new curve extraction, whether the current center point is in the list is checked, if so, the point is skipped to ensure that each center point is only selected once.

According to the principle, the number of single extraction can be increased during curve extraction, and the division of various curved surface unit combinations can be completed. For example, when a module with a complex curved surface needs to be processed, multiple curves can be extracted at the same time, and the curved surface is divided into multiple parts for combination processing by reasonably setting the starting point and the ending point of the curves.

Through the embodiment, the elevation combination information can be determined, and automatic processing of the elevation combination is realized so as to facilitate subsequent classification.

S13, generating the multi-type elevation combination of the integral building block model according to the elevation information and the elevation combination information.

In this embodiment, the generating the multi-type facade combination of the integral building block model according to the facade information and the facade combination information includes:

The balcony is usually a space for people to move and relax from the aspect of building function, and is provided with protective facilities such as railings, the wall body mainly plays roles of bearing, separating the space and the like, and the inner side and the outer side of the balcony are differentiated from the aspects of space position, orientation, enclosure structure and the like from the aspect of geometric and physical characteristics. The inner side and the outer side of the balcony are distinguished from the wall surface, so that module surfaces with different functions and characteristics can be correctly classified when the module surfaces are in coplanar grouping.

For example, please refer to fig. 4, which is a schematic diagram of the multi-type facade combination of the present invention. A in fig. 4 is the coplanar single type of elevation combination, b in fig. 4 is the facing single type of elevation combination, c in fig. 4 is the facing combination type of elevation combination, and d in fig. 4 is the coplanar combination type of elevation combination. Specifically, a has two groups of vertical surfaces which are not coplanar, b has one group of vertical surfaces which have the same orientation, c has different vertical surface combinations because all vertical surfaces with the same orientation are divided according to the orientation and the vertical surface module combination of the module level is considered simultaneously compared with b, and therefore, the color of the side surface of c is distinguished, and the color of the side surface of c is not distinguished, as b has all vertical surfaces with the same orientation divided into one group, but the color of the side surface of c is distinguished (see dark gray part of the side surface), and d has the same principle as the combination of the three outermost vertical surfaces compared with a, and is divided into different vertical surface combinations because all vertical surfaces with the same vertical surface module combination (namely, the vertical surface module combination of the module level is divided).

In the above embodiment, multiple geometric information such as the serial number, the coplanar information, the orientation, the area size, the length, the height, the module combination condition and the like of the vertical face can be determined according to the vertical face information and the vertical face combination information, and multiple types of vertical face combinations can be generated according to different characteristics in different areas of the opposite face, so that the corresponding processing can be performed according to different vertical face combinations.

S14, carrying out elevation detail giving treatment on the integral building block model according to the multi-type elevation combination to obtain the building elevation of the integral building block model.

In this embodiment, the performing, according to the multi-type facade combination, facade detail assignment processing on the integral building block model, to obtain a building facade of the integral building block model includes:

acquiring elevation detail information of the reference surface;

The reference surface has the same size as the reference surface to be endowed with the elevation details. Meanwhile, for geometric objects such as doors and windows, sun shields and the like arranged on the vertical surfaces, the reference surfaces and the reference surfaces keep consistent relative position relation. The reference surface shape may be rectangular or other shape. In selecting the reference surface, a representative and easy to operate surface may be preferentially selected, such as a surface on a major facade of a building that contains a large number of typical geometric objects.

The normal vector angle difference between the reference surface and each reference surface to be processed can be calculated by adopting a vector dot product formula.

The method comprises the steps of determining the position relation between the reference surface and the center point of each reference surface to be processed, and calculating a motion vector for positioning so as to reflect the difference of the reference surface and each reference surface in the space position. In calculating the motion vector, the coordinates of the two center points may be subtracted and the resulting vector determined as the motion vector.

The vertical face objects (such as doors and windows, sunshade facilities and the like) filled on the reference surface can be accurately added to all other reference surfaces needing to be designed. Therefore, the information assignment to other similar vertical surfaces can be completed rapidly by carrying out one-time design or adjustment on the reference surface. When the objects are added, the objects on the reference surface can be rotated, translated and the like according to the calculated angle difference and the calculated movement vector, so that the objects are accurately added on the reference surface, rapid facade detail assignment can be realized, the objects do not need to be copied one by one, and the generation efficiency of the building facade is improved.

For example, please refer to fig. 5, which is a schematic diagram of a building facade according to the present invention. The building facade can be quickly generated by giving the facade details on the basis of various facade combinations.

In this embodiment, after the building facade of the integral building block model is obtained, the integral building model may be output to a designated terminal device or interface for modification and perfection, and put into use.
