[0101] SUMMARY OF THE DISCLOSURE

[0102] The technical solution provided by the embodiment of the present disclosure is used to solve the problem of automatic generation of house design drawings, and can be applied to a variety of business fields, such as home decoration, architectural design, house transactions, etc. The design drawings generated by the technical solution of this embodiment can also be called computer-aided design drawings (CAD drawings). In related technologies, CAD drawings require manual measurement and professional software design and generation, which is cumbersome and time-consuming.

[0103] The technical solution disclosed in the present invention can automatically generate CAD drawings based on the inner wall line vector data without manual intervention, with high efficiency and accuracy.

[0104] Exemplary Methods

[0105] Figure 1 1 is a flow chart of an embodiment of a method for generating a design drawing of the present disclosure; the method for generating a design drawing can be applied to electronic devices (such as computer systems, servers), such as Figure 1 As shown, the method for generating the design drawing includes the following steps:

[0106] In step 101, first representation data of exterior wall lines are generated based on interior wall line vector data of a target house.

[0107] In the present disclosure, the inner wall line vector data includes the second characterization data of the inner wall line and the third characterization data of the wall attachment. Among them, the second characterization data of the inner wall line may include the starting point coordinates and the end point coordinates of each wall corresponding to the inner wall line and the line data of the inner wall line, and the line data of the inner wall line may be described by a sequence coordinate chain with uniform or uneven intervals. The wall attachment may be an object such as a window, door, weak current box, etc. on the wall. The third characterization data of the wall attachment may include information such as the height and width used to characterize the size of the wall attachment, as well as coordinate information used to characterize the position of the wall attachment.

[0108] In this embodiment, the polygon formed by the outer wall line can be obtained by expanding and contracting the inner wall line, and then the third characterization data of the outer wall line can be obtained. Figure 2 The illustrated embodiment will not be described in detail here.

[0109] The first characterization data of the exterior wall line may include the starting point coordinates and the end point coordinates of the exterior wall line corresponding to each wall and the line data of the exterior wall line. The line data of the exterior wall line may be described by a sequence coordinate chain with uniform or uneven intervals.

[0110] In step 102, based on the first characterization data, the second characterization data and the third characterization data, the positional relationship between the wall attachment and the inner wall and the outer wall and the scale data are determined.

[0111] In the present disclosure, a wall attachment, such as a window, may be located on an outer wall or an inner wall. The positional relationship between the wall attachment and the inner wall or the outer wall is used to indicate the position of the wall attachment on the wall. The position of the wall attachment on the outer wall or the inner wall may be determined by judging whether the wall attachment intersects with the outer wall line or the inner wall line.

[0112] In the present disclosure, the scale data may include external scale data and internal scale data. The external scale data is used to indicate the three-layer scale lines and dimension information marked on the outermost side of the CAD drawing, and is composed of dimension lines, extension lines (i.e., dimension boundaries), dimension text (i.e., dimension numbers), etc. The external scale data is usually located at the outermost side of the CAD drawing, with three dimension lines marked in the horizontal direction and the vertical direction, such as Figure 8As shown, the external scale data may include the total dimensions of the house in the horizontal direction, such as the total length and total width, as well as the axial dimensions of the house such as the span and depth, and the detailed dimensions of the wall sections of the house's exterior walls and door and window openings.

[0113] In specific implementation, based on the positional relationship between each endpoint in the first characterization data, the second characterization data, and the third characterization data and the center point of the target house, projection can be performed in the direction of the closest distance to obtain the intersection point with the three-layer ruler line and generate the external ruler data. For example, a point located at the upper left position of the center point of the target house can be projected to the left and upper sides respectively, and fall on the three-layer ruler lines on the left and upper sides. A point located at the lower right position of the center point of the target house can be projected to the right and lower sides respectively, and fall on the three-layer ruler lines on the right and lower sides. See Figure 8 Among them, the target house center point can be understood as the point at the center position of the target house.

[0114] Internal ruler data is used to indicate the annotation information marked inside the apartment area of ​​the CAD drawing. It can be generated based on the size information of each wall attachment (such as the height and width of the window), the location information of the attachment (such as the height of the window from the ground), and the size information of each room of the target house (such as the width, length, and area of ​​the master bedroom). See Figure 8 .

[0115] In this embodiment, the dimension information of the room can be determined based on the point data and line data of the second characterization data of the inner wall line, and the detailed dimensions of the door and window openings, etc. can be determined based on the third annotation information of the wall attachments; the dimension information such as the wall section of the outer wall of the house can be determined based on the first characterization data of the outer wall line. Therefore, the outer scale data and the inner scale data can be determined by combining the first characterization data, the second characterization data and the third characterization data.

[0116] In this embodiment, the specific implementation method of determining the position of the wall attachment according to the first characterization data, the second characterization data and the third characterization data can be found in Figure 5 The illustrated embodiment will not be described in detail here.

[0117] In step 103, the display area of ​​each data in the inner scale data is determined, wherein the display areas of each data in the inner scale data do not overlap with each other.

[0118] In the present disclosure, each data in the internal scale data may include the size information of the wall attachments and the size information of each room, for example, the width (CK: 1007mm), height (CH: 1387mm), height from the ground (CX: 777mm) of window 1, the width (CK: 1307mm), height (CH: 1387mm), height from the ground (CX: 777mm) of window 2, etc. The display areas of the size information of different wall attachments or different rooms cannot overlap to avoid collision of size information.

[0119] In this embodiment, the specific implementation method of determining the display area of ​​each data in the inner scale data can be found in Figure 6 The illustrated embodiment will not be described in detail here.

[0120] In step 104, a design drawing of the target house is generated based on the first characterization data, the second characterization data, the positional relationship, the scale data, and the display area.

[0121] In the present disclosure, the design drawing is a directly usable and editable CAD file, such as a Drawing Web Format (DWG) file and a Drawing Exchange Format (DXF) file.

[0122] In this embodiment, a design drawing can be obtained by drawing according to the first characterization data, the second characterization data, the position relationship, the scale data, and the display areas of the different scale data.

[0123] In the above steps 101 to 104, when generating a design drawing, the first characterization data of the exterior wall line can be generated based on the interior wall line vector data of the target house, and the interior wall line vector data includes the second characterization data of the interior wall line and the third characterization data of the wall attachment; based on the first characterization data, the second characterization data and the third characterization data, the positional relationship between the wall attachment and the interior wall line and the exterior wall line and the scale data are determined; the display area of ​​each data in the interior scale data is determined, wherein the display area of ​​each data in the interior scale data does not overlap; based on the first characterization data, the second characterization data, the positional relationship, the scale data and the display area, the design drawing of the target house is generated. Therefore, the technical solution disclosed in the present invention can automatically generate a design drawing based on the interior wall line vector data of the target house, and the display of each scale data in the generated design drawing does not overlap, the display effect is good, and no manual participation is required, and the generation cost is low.

[0124] In order to better illustrate the scheme for generating the design drawing of the present invention, another embodiment is used below for illustration.

[0125] Figure 2FIG. 1 is a flow chart of determining exterior wall line data in a method for generating a design drawing provided by an exemplary embodiment of the present disclosure; this embodiment takes how to determine exterior wall line data as an example for exemplary description, such as Figure 2 As shown, the following steps are included:

[0126] In step 201, at least one first polygon formed by the interior wall lines is determined based on second characterization data of the interior wall lines.

[0127] In this embodiment, one or more first polygons may be obtained based on the second characterization data of the interior wall line. Multiple first polygons can represent multiple groups of continuous interior wall lines. For example, if there is a patio in the house, there is an independent first polygon inside the house, or if there is an independent space area indoors that is connected to other indoor areas only through windows, then the independent space area can also form a first polygon.

[0128] In this embodiment, in order to facilitate subsequent operations, each first polygon can be corrected to counterclockwise or clockwise, and the starting point and end point of the wall attachment can be adjusted. For example, the first polygon is adjusted to the clockwise direction, and the direction from the starting point to the end point of the window 1 on the first polygon does not conform to the clockwise direction, then the starting point and the end point can be swapped, that is, the starting point is used as the end point, and the end point is used as the starting point. In this implementation, by correcting the order of the first polygons to counterclockwise or clockwise, and adjusting the starting point and end point of the wall attachment accordingly, a group of orderly wall attachments can be obtained, which is helpful for subsequent CAD drawing.

[0129] In step 202, at least one first polygon is expanded by a first distance to obtain at least one second polygon.

[0130] In the present disclosure, the first distance is a distance that exceeds the value of the exterior wall thickness corresponding to the value in the CAD drawing. For example, the exterior wall thickness is a fixed value of 40 cm, which corresponds to 1 cm in the CAD drawing. The first distance can be a value exceeding 1 cm, such as 2 cm.

[0131] In some implementations, the operation of expanding the first polygon refers to expanding each side of a polygon outward by a fixed distance to form a new second polygon.

[0132] In step 203, at least one second polygon is retracted by a second distance to obtain at least one third polygon, and the difference between the first distance and the second distance is a value representing the thickness of the exterior wall.

[0133] In the present disclosure, the second distance is a value smaller than the first distance, and the difference between the second distance and the first distance is a value representing the thickness of the exterior wall. For example, the thickness of the exterior wall is a fixed value of 40 cm, which corresponds to 1 cm in the CAD drawing. The first distance can be a value greater than 1 cm, such as 2 cm. The second distance can be 1 cm.

[0134] In this embodiment, shrinking the second polygon means moving each side of the second polygon inward by a certain distance to form a new, smaller polygon. In this implementation, the buffer tool can be used to set a negative distance to achieve polygon shrinkage, and polygons with an area smaller than a specific value can be screened out.

[0135] In this embodiment, the expansion and contraction operations of step 202 and step 203 can be implemented through buffer operations, thereby generating at least one third polygon corresponding to at least one first polygon formed by the inner wall line, and the obtained third polygon realizes the flattening of the irregular corners of the first polygon, while only expanding the first polygon by 1 times the characterization value of the outer wall thickness cannot achieve the effect of flattening the irregular corners of the first polygon.

[0136] In step 204, first characterization data of the exterior wall line is generated based on at least one third polygon.

[0137] In specific implementation, the third polygons can be optimized according to the number of the third polygons to obtain the first characterization data of the outer wall line. In response to the number of the third polygons being one, the third polygons are optimized to obtain the fourth polygon formed by the outer wall line, and the characterization data of the fourth polygon is the first characterization data of the outer wall line; in response to the number of the third polygons being two or more, at least one third polygon is sequentially subjected to the union and convex hull processing to obtain the fifth polygon, and then the fifth polygon is optimized to obtain the sixth polygon formed by the outer wall line, and the characterization data of the sixth polygon is the first characterization data of the outer wall line.

[0138] In some embodiments, the obtained third polygon may be uneven, which makes the CAD drawing effect poor. However, by optimizing the third polygon to be smooth, a better effect can be achieved. For example, when there are some short and small line segments on the third polygon, the short and small line segments and the adjacent edge lines can be smoothed, such as Figure 3 As shown; or, when the angle of the adjacent edge lines on the third polygon is less than a certain threshold, the adjacent edge lines can be flattened into one edge line, such as Figure 4 In this implementation, by optimizing the third polygon, a better outer wall line polygon can be obtained, thereby obtaining more accurate first representation data.

[0139] In other embodiments, if there are more than two third polygons, the third polygon areas can be unioned and then the polygons after the union can be convex hull processed to obtain the fifth polygon. Some unevenness that may exist in the fifth polygon can be smoothed and optimized to achieve better results.

[0140] In this embodiment, the convex hull processing performed on the polygon refers to an operation of finding the smallest convex polygon that contains all vertices of the original polygon (the polygon after taking the union in the present disclosure).

[0141] In some implementations, after the polygon is optimized, the characterization data of the optimized polygon may be determined as the first characterization data of the exterior wall line.

[0142] Through the above steps 201 to 204, the characterization data of the exterior wall line is determined based on the second characterization data of the interior wall line, and by expanding and then contracting the polygons of the interior wall line and further optimizing the obtained exterior wall line polygons, the contour of the obtained exterior wall line can be made smooth, which is beneficial to improving the effect of the subsequent CAD drawing.

[0143] Figure 5 The present invention provides a schematic flow chart of determining the position of a wall attachment in a method for generating a design drawing according to an exemplary embodiment of the present invention; this embodiment uses how to determine the position of a wall attachment as an example for exemplary description, such as Figure 5 As shown, the following steps are included:

[0144] In step 501, based on two endpoints, a line segment with a length of a set value is drawn in a direction perpendicular to the inner wall line and / or the outer wall line.

[0145] In this embodiment, for each wall attachment, the corresponding third characterization data may include the coordinates of the two end points of the wall attachment, and two line segments with a set length may be drawn along the vertical direction of the wall line from the two end points to the outer wall line and the inner wall line, or the center points of the two end points of the wall attachment may be determined first, and then line segments with a set length may be drawn along the vertical direction of the wall line from the center point to the outer wall line and the inner wall line, respectively. The set value may be determined based on the thickness of the wall attachment, for example, the thickness of the window usually does not exceed the thickness of the wall, and the size of the set value cannot exceed the characterization value corresponding to the window thickness in the CAD drawing.

[0146] In step 502, based on the intersection of the line segment and the inner wall line and / or the outer wall line, the positional relationship between the wall attachment and the inner wall or the outer wall is determined.

[0147] In some embodiments, if the line segment intersects with the outer wall line but not the inner wall line, it can be determined that the wall attachment is located on the outer wall; if the line segment intersects with the inner wall line but not the outer wall line, it can be determined that the wall attachment is located on the inner wall.

[0148] In some optional implementations, it is further possible to determine whether adjacent windows are a continuous window based on the distance between the windows. For example, two windows located on two adjacent walls may be an L-shaped window. Fig. 9 , since the distance between the two windows numbered 91 and 92 is 0, it can be determined that the two windows are a complete continuous window, and the window can be adjusted to a continuous L-shaped window. In this implementation, the display effect and accuracy of the wall attachments can be further improved.

[0149] Through the above steps 501 to 502, the position of each wall attachment can be calculated and the wall attachments can be further grouped and integrated, which provides a good solution for improving the accuracy of the wall attachments in the subsequently generated CAD drawing.

[0150] Figure 6 The present invention provides a flowchart of determining a display area of ​​ruler data in a method for generating a design drawing according to an exemplary embodiment of the present invention. The present embodiment provides an exemplary description by taking how to determine a display area of ​​ruler data as an example.

[0151] In step 601, each data in the internal scale data is abstracted into a component to obtain at least two components.

[0152] In the present disclosure, each data in the internal ruler data can be abstracted into components according to different granularities. In some embodiments, it can be abstracted into components according to the granularity of the object. For example, the ruler data of each wall attachment is abstracted into a component, such as the width, height, and height from the ground of window 1 are abstracted as component 1; the width, height, and height from the ground of window 2 are abstracted as component 2, and the length, width, and area information of room 1 are abstracted as component 3, etc. In other embodiments, it can also be abstracted into a component according to a smaller granularity, such as a text or a legend. For example, the width of window 1 is abstracted as component 1, the height of window 1 is abstracted as component 2, and the height of window 1 from the ground is abstracted as component 3. The present disclosure does not limit the granularity of abstracting each data in the internal ruler data into components.

[0153] In step 602, the display area of ​​each component is determined in sequence, wherein the display area of ​​each component does not overlap with the occupied space area, and the occupied space area includes the space area occupied by the data of the determined display area.

[0154] In the present disclosure, determining the display area of ​​each component in sequence can be understood as determining the display area of ​​each component one by one, and the display area of ​​each component does not overlap with the occupied space area.

[0155] In some embodiments, the method of determining the display area of ​​each component can be seen in Figure 7 The illustrated embodiment will not be described in detail here.

[0156] Through the above steps 601 to 602, the display area of ​​each component can be determined by abstracting each data in the internal scale data into a component. The display areas of each component do not collide with each other, which helps to improve the display effect of the CAD drawing.

[0157] Figure 7 A schematic diagram of a flow chart of determining the display area of ​​each component in a method for generating a design drawing provided by an exemplary embodiment of the present disclosure; this embodiment takes how to determine the display area of ​​each component as an example for exemplary description, such as Figure 7 As shown, the following steps are included:

[0158] In step 701, an occupied space area is created, and the initial value of the occupied space area is empty.

[0159] The occupied space area is used to indicate the space area occupied by each component of the determined display area, and its initial value is empty, that is, before the display area of ​​any component is determined, the occupied space area is empty.

[0160] In step 702, a target component of a display area to be determined is selected from at least two components.

[0161] In some implementations, at least two components abstracted from the inner scale data may be added to a component list in advance, and the target component of the current display area to be determined may be selected by traversing the component list.

[0162] It can be understood that the components in the component list can be sorted in a spatial order. For example, each wall attachment can be added to the component list in a clockwise order on the wall. This allows the display area of ​​each component to be determined in a certain order. For example, if window 1 is in front of window 2 in a clockwise direction, the display area of ​​window 1 can be determined first, and then the display area of ​​window 2 can be determined.

[0163] In step 703, the overlapping state between the initial occupied area of ​​the target component and the occupied space area is determined.

[0164] In the present disclosure, the initial occupied area is the original occupied area generated when the internal scale data is abstracted to obtain the component. The initial occupied area of ​​each component is usually related to the position of the wall attachment corresponding to the component. For example, the initial occupied area of ​​the component corresponding to the scale data of window 1 is located below the position of window 1, and the initial occupied area of ​​the component corresponding to the scale data of room 1 is located in the middle of room 1, etc.

[0165] The initial occupied area can be characterized according to information such as the area center point, width, height, etc. The occupied space area can be composed of multiple discontinuous occupied areas. For example, the occupied space area includes display area 1 of the component corresponding to the scale data of window 1 and display area 2 of the component corresponding to the scale data of window 2. The two display areas may be two isolated space areas, and the characterization information (area center point, width, height) of the two display areas can be recorded separately.

[0166] According to the characterization information of the initial occupied area and the characterization information of the occupied space area, it can be determined whether there is overlap between the two, and the overlapping area can be further determined.

[0167] Further, when the overlapping state indicates no overlap, step 704 may be executed; further, when the overlapping state indicates overlap, step 705 may be executed.

[0168] In step 704, in response to the overlap status indicating no overlap, the initial occupied area of ​​the target component is determined as the display area of ​​the target component, and the initial occupied area is added to the occupied space area.

[0169] The above step 702 is iteratively performed until all components have determined display areas, that is, all internal scale data have determined display areas.

[0170] In step 705 , in response to the overlap status indicating overlap, the display area of ​​the target component is adjusted until it does not overlap with the occupied space area, and the initial occupied area is added to the occupied space area.

[0171] In some embodiments, when the initial occupied area of ​​the target component overlaps with the occupied space area, multiple candidate components can be defined in sequence based on a fixed step size, and the occupied areas of all candidate components can be constituted into a large auxiliary occupied area. The difference between the auxiliary occupied area and the occupied area is determined to obtain an area where no overlap will occur, and the display area of ​​the target component can be adjusted to the area where no overlap will occur.

[0172] In other embodiments, the target component may be moved from the initial occupied area to a direction opposite to the overlapping portion until it no longer overlaps with the occupied space area, thereby obtaining a display area of ​​the target component.

[0173] After the display area of ​​the target component is determined, the display area can be added to the occupied space area to obtain an updated occupied space area.

[0174] The above step 702 is iteratively performed until all components have determined display areas, that is, all inner scale data have determined display areas, and the display areas of all inner scale data will not collide.

[0175] In the above steps 701 to 705, by constructing the occupied space area and iteratively determining the display area of ​​each component based on the occupied space area, it is possible to achieve anti-collision display of all internal scale data and improve the display effect of the CAD drawing.
