[0038] The present disclosure will be further described in detail below with reference to the accompanying drawings. The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise specified.

[0039] In addition, in order to better illustrate the present disclosure, numerous specific details are given in the following specific embodiments. It should be understood by those skilled in the art that the present disclosure can also be implemented without certain specific details. In some examples, methods, means, components and circuits well known to those skilled in the art are not described in detail in order to highlight the main purpose of the present disclosure.

[0040] The terms "first", "second", etc. in this disclosure are used to distinguish similar objects, and are not necessarily used to describe a specific order or precedence. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, including a series of steps or units. The method, system, product or device is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0041] There are roughly two types of home design software on the market. One type requires all components in the home model to be preset in advance, which can be understood as the need to preset in advance which components the home model consists of, and the need to use parameter expressions or specify specific values ​​based on the size parameters of the home model to obtain the geometric expression of each component in the home model. Then, through the geometric expression of each component, the construction of the entire home model is completed. After the home model is built, if you want to continue adding components, you need to readjust the overall modeling of the home model and update each component of the home model to complete the addition of new components. The other type supports dynamic addition of components, but the user needs to calculate the geometric data such as the size and position of the component, and when adjusting the cabinet geometry data, the geometric data of the component cannot be automatically recalculated.

[0042] In view of this, a method for generating a home model is proposed in the embodiment of the present disclosure, which can make the process of adding components more convenient. Figure 1 As shown, including:

[0043] S101, in response to a first user operation, determining a framework model of a home model.

[0044] Exemplarily, the first user operation may be as follows: Figure 2 As shown in , clicking "Create Empty Cabinet" means that the user customizes the length, depth, and height of the home model, and can also obtain the corresponding finished model from the material library, thereby automatically extracting the length, depth, and height of the finished model to construct a frame model. It can be understood that any operation that can determine the length, depth, height, and other information of the home model can be operated by the first user.

[0045] The frame model can be understood as the smallest cube that can surround the home model. For example, when the home model is a wardrobe, the frame model can be the outer frame of the wardrobe.

[0046] S102: In response to a second user operation, determine a drawing plane and a drawing type created based on a coordinate system of a framework model.

[0047] When implemented, the drawing plane represents the reference plane selected by the user, and the coordinate system and the reference plane are combined to provide a visual display to the user, such as Figure 2 As shown, the drawing plane can be exemplarily any one of the front view, left view, top view, rear view, right view, and bottom view. Among them, the front view can be understood as the visual effect of the home model observed by the user from the front perspective of the home model; the left view can be understood as the visual effect of the home model observed by the user from the left perspective of the home model; the top view can be understood as the visual effect of the home model observed by the user from the top perspective of the home model; other drawing planes are similar to the above content, and the embodiments of the present disclosure will not explain them one by one. Based on the drawing plane, it is displayed to the user so that the user can generate a home model through simple and intuitive visualization operations.

[0048] The drawing type indicates the component type included in the home model. Exemplary drawing types include cabinet panels, skirting boards, drawers, wardrobe ducts, end panels, pull strips, and door panels. Drawing types can be adaptively increased or decreased based on subsequent usage.

[0049] In addition to the above two operations, since each user may have different requirements for components, each user can customize the component material, component color, texture, component thickness and other information based on actual conditions. For example, the component thickness can be set to 18mm, and the component texture can be walnut grain. Each information can be preset based on the visual interface for component-related content in the home model, so that the home model is closer to the user's expectations.

[0050] S103 , in response to the operation track in the screen coordinate system, determining a target component corresponding to the operation track in the drawing type based on the drawing plane.

[0051] During implementation, the operation trajectory is the trajectory from the starting point to the end point drawn by the user.

[0052] When the user uses a computer mouse, the operation track can be understood as the user pressing the left mouse button and starting to drag continuously until the user completes the drawing and releases the left mouse button to obtain the corresponding operation track.

[0053] In addition, when the user uses a touch screen, the operation track can be understood as the user using a stylus to start dragging continuously until the user completes drawing and lifts the stylus to obtain the corresponding operation track.

[0054] It should be noted that no matter what kind of drawing tool is used, any method that can express the user's drawing intention can be applied to the embodiments of the present disclosure, and the embodiments of the present disclosure are not limited to this.

[0055] S104, using the model structure of the framework model as a constraint and referring to the structural process requirements of the target component, installing the target component into the framework model.

[0056] During implementation, the size information of the model structure of the framework model is used as a constraint. The structural process requirements of each target component may be different, so the target component needs to be installed into the framework model based on the structural process requirements corresponding to the target component.

[0057] It should be noted that S101-S104 is the installation process of any target component in the home model. Each home model may include multiple components. When multiple components are installed, a further improved home model is obtained.

[0058] In the disclosed embodiment, the target component desired by the user can be obtained based on a simple operation trajectory, which can lower the operation threshold, so that the user can complete the component adding process based on simple operations. At the same time, combined with the visual drawing plane, the user can intuitively observe the placement of the components in the home model, which improves the flexibility and scalability of the design. Based on the solution proposed in the disclosed embodiment, there is no need to preset the specific parameters of all components in advance or manually calculate the specific parameters of the components (such as position and size), which simplifies the process of adding components and uses a more intuitive and fast interaction method, so that the user can complete the component adding process more quickly.

[0059] In some embodiments, the target component corresponding to the operation trajectory in the drawing type is determined based on the drawing plane, such as Figure 3 As shown, it can be implemented as:

[0060] S301, extracting the starting point and the ending point of the operation trajectory.

[0061] The starting point is the position where the user presses the left mouse button, and the ending point is the position where the user releases the left mouse button.

[0062] It should be noted that the mouse is only used for exemplary description, and gesture touch and stylus touch are both within the protection scope of the embodiments of the present disclosure.

[0063] S302, mapping the starting point and the end point from the screen coordinate system to the coordinate system of the framework model to obtain a 3D line.

[0064] During implementation, the coordinates of the starting point and the ending point need to be mapped from the screen coordinate system to the coordinate system of the frame model first, and the coordinates of the starting point and the ending point in the coordinate system of the frame model are obtained, which can be understood as the starting coordinates and the ending coordinates. By connecting the starting coordinates and the ending coordinates, the 3D line can be determined.

[0065] In addition, for the convenience of users, the starting point and the ending point can be mapped from the screen coordinate system to the coordinate system of the framework model to obtain the starting coordinates and the ending coordinates respectively through Unity (game engine), Unreal Engine (Unreal Engine), OpenGL (Open Graphics Library), etc.

[0066] S303, projecting the 3D line onto the drawing plane to obtain a drawing line.

[0067] For example, Figure 4 As shown, when the user selects the front view as the drawing plane, the black solid line on the right is the drawing line, and the black spheres at both ends are the starting point and the ending point.

[0068] Among them, due to the limited precision of manual operation, the operation trajectory may have jitter or deviation. For the user's intuitive experience, the starting point and the end point can be extracted, and then based on the mapping method, the user can get what he sees, and intuitively feel the drawing line obtained based on the operation trajectory. Figure 4 As shown, the drawn line appears in the form of a line segment.

[0069] S304, identifying the direction attribute and / or position attribute of the drawn line.

[0070] The direction attribute may include horizontal line, vertical line, oblique line, etc.

[0071] In some embodiments, identifying the direction attribute of the drawing line may be implemented as follows: when the angle between the drawing line and the horizontal axis in the drawing plane is less than a first preset angle, determining that the direction attribute of the drawing line is a horizontal line.

[0072] During implementation, the coordinate system in which the drawing line is located is a two-dimensional coordinate system, the horizontal axis is exemplarily the x-axis, the vertical axis is the y-axis, and the first preset angle can be exemplarily 15°. In this case, Figure 4 As shown by the plotted line, assuming Figure 4 When the angle between the drawn line and the x-axis is 10°, since the angle between the drawn line and the x-axis is less than 15°, the direction attribute of the drawn line is determined to be a horizontal line.

[0073] It should be noted that the aforementioned numerical values ​​are only used for illustrative purposes and can be adjusted based on actual conditions.

[0074] In the embodiment of the present disclosure, since manual operation may cause deviations in the angle of the drawn line, a method of using an angle less than a first preset angle with the horizontal axis in the drawing plane is used to achieve recognition of the direction attribute of the drawn line as a horizontal line, thereby ensuring the user's fault tolerance to a large extent. Based on this method, the accuracy is guaranteed while reducing the complexity of the operation.

[0075] In some embodiments, identifying the direction attribute of the drawing line may be implemented as follows: when the angle between the drawing line and the vertical axis in the drawing plane is less than a second preset angle, determining that the direction attribute of the drawing line is a vertical line.

[0076] Based on the foregoing knowledge, the vertical axis is the y-axis, and the second preset angle can be 15° for example. In this case, when the angle between the drawn line and the y-axis is 10°, since the angle between the drawn line and the y-axis is less than 15°, the direction attribute of the drawn line is determined to be a vertical line.

[0077] In the embodiment of the present disclosure, based on the difference information between the angle of the drawing line and the vertical axis, the deviation caused by the user in the drawing process is guaranteed to a large extent. When the difference information is less than the second preset angle, the direction attribute of the drawing line is identified as a vertical line. While ensuring the accuracy, the whole operation is simple and easy to implement.

[0078] In some embodiments, identifying the direction attribute of a drawing line can be implemented as follows: calculating the angle between the drawing line and each coordinate axis in the drawing plane, and determining the coordinate axis with the smallest angle as the first coordinate axis; when the angle between the drawing line and the first coordinate axis is not less than a third preset angle, determining the direction attribute of the drawing line to be a diagonal line.

[0079] During implementation, when the third preset angle is exemplarily 15°, the angle between the drawn line and each coordinate axis is calculated. When the angle between the drawn line and the x-axis is 30° and the angle between the drawn line and the y-axis is 60°, the x-axis is determined to be the first coordinate axis. In addition, if it is determined that the angle between the drawn line and the x-axis is greater than the third preset angle, it is determined to be a diagonal line.

[0080] It should be noted that the first preset angle, the second preset angle, and the third preset angle may be the same or different, and may be adjusted based on actual conditions, which is not limited in this embodiment of the present disclosure.

[0081] In the embodiment of the present disclosure, the direction attribute of the drawn line is identified as a diagonal line based on the angle, and a relatively simple method can be used to ensure the user's error tolerance.

[0082] In some embodiments, identifying the position attribute of the drawing line can be implemented as follows: projecting the drawing line and the frame model of the home model onto the drawing plane; and determining the position attribute of the drawing line based on the positional relationship between the projection of the drawing line and the projection of the frame model.

[0083] The position attribute of the drawing line includes that the drawing line is located inside the frame model of the home model or the drawing line is located on the facade of the frame model of the home model.

[0084] In the disclosed embodiment, the projection-based method can enable the user to draw in a flexible manner so that what the user sees is what the user gets. Guided by the user's operation trajectory, in order to accurately understand the drawing intention, the position attributes of the drawing line can be accurately identified based on the projection method, thereby laying the foundation for accurately identifying the location of the target component.

[0085] In some embodiments, the position attribute of the drawing line is determined based on the positional relationship between the projection of the drawing line and the projection of the frame model. This can be implemented as follows: when the projection of the drawing line does not cross the projection of the frame model and the projection of the drawing line all falls within the projection of the frame model, the position attribute of the drawing line is determined to be inside the frame model of the home model.

[0086] Specific as Figure 5 As shown, when all the drawing lines are located within the projection of the framework model, the position attribute of the drawing lines is determined to be inside the framework model of the home model.

[0087] It can be understood that the components that need to be drawn by the drawing line are shelves, drawers, clothes hangers and other components.

[0088] In the disclosed embodiment, based on the visualization interface, the user can flexibly draw the home model to obtain the drawing line, and then further identify the position of the drawing line based on the projection method, and identify that the position attribute of the drawing line is that the drawing line is inside the frame model of the home model.

[0089] In some embodiments, the position attribute of the drawing line is determined based on the positional relationship between the projection of the drawing line and the projection of the frame model. This can be implemented as follows: when the projection of the drawing line does not cross the projection of the frame model and the projection of the drawing line all falls outside the projection of the frame model, the position attribute of the drawing line is determined to be on the facade of the frame model of the home model.

[0090] Specific as Figure 6 As shown, when all the drawing lines are located outside the projection of the frame model, the position attribute of the drawing lines is determined to be on the facade of the frame model of the home model.

[0091] It can be understood that the target component to be drawn by the drawing line may be a side panel, a finishing strip, or other components.

[0092] In the disclosed embodiment, based on a visualization interface, the user can flexibly and dynamically draw the home model, so that the user can visually obtain the drawing lines, and then further identify the position of the drawing lines based on projection, and identify the position attribute of the drawing lines as being located on the facade of the frame model of the home model.

[0093] In some embodiments, determining the position attribute of the drawing line based on the positional relationship between the projection of the drawing line and the projection of the framework model may be implemented as follows:

[0094] Step A1, when the projection of the drawing line crosses the projection of the framework model, determine the first ratio and the second ratio; wherein the first ratio represents the ratio of the line segment of the drawing line projection falling within the projection of the framework model to the overall line segment of the drawing line; the second ratio represents the ratio of the line segment of the drawing line projection falling outside the projection of the framework model to the overall line segment of the drawing line.

[0095] Step A2: when the first proportion is greater than the second proportion, determine the position attribute of the drawing line to be inside the frame model of the home model.

[0096] Specific as Figure 7 As shown on the left, the projection part of the drawing line falling within the frame is larger than the projection part falling outside the frame. In this case, the position attribute of the drawing line is determined to be inside the frame model of the home model.

[0097] Step A3, when the first proportion is not greater than the second proportion, determining the position attribute of the drawing line to be on the facade of the frame model of the home model.

[0098] Specific as Figure 7 As shown on the right, the projection part of the drawing line falling within the frame is smaller than the projection part falling outside the frame. In this case, the position attribute of the drawing line is determined to be inside the frame model of the home model.

[0099] In the disclosed embodiment, taking into account the user's operating habits and the possible errors in gesture drawing, the position attribute of the drawing line can be determined based on the position ratio of the projection of the drawing line and the projection of the framework model to ensure the accuracy of the position attribute of the drawing line.

[0100] S305 , determining a target component corresponding to the drawing line based on different direction attributes and / or position attributes and the corresponding relationship between different component types in the drawing type.

[0101] In some embodiments, based on different direction attributes and the correspondence between different component types in the drawing type, determining the target component corresponding to the drawing line may exemplarily include:

[0102] When the drawing type is drawer and the direction attribute is horizontal line, the target component is determined to be a horizontal drawer.

[0103] In some embodiments, when the drawing type is a drawer and the direction attribute is a horizontal line, the attribute parameters of the drawer can be customized by the user, and its visual interface is exemplarily as follows: Figure 8 As shown in the figure, the left half is the preset operation of the attribute parameters of the drawer, and the right half is the real-time preview effect of the drawer. The attribute parameters of the drawer may include alignment, drawer height, drawer style, masking method, baffle parameters, etc.

[0104] When the drawing type is a drawer and the direction attribute is a vertical line, the target component is determined to be a vertical drawer.

[0105] When the drawing type is cabinet panel and the direction attribute is oblique line, the target component is determined to be the back panel.

[0106] Other drawing types can have corresponding preset operations of attribute parameters, and the embodiment of the present disclosure does not explain each interface one by one. The attribute parameters corresponding to each drawing type can be set based on actual conditions. For example, the attribute parameters of the cabinet panel can include component thickness, the attribute parameters of the door panel can include door panel style, door panel material, etc., and the attribute parameters of the closing strip can include information such as the width of the closing strip. The specific attribute parameters included in each drawing type can be determined based on actual conditions, and the embodiment of the present disclosure does not limit them here.

[0107] It should be noted that the above is only an exemplary description, and there may be other corresponding relationships, which will not be described one by one in the embodiments of the present disclosure.

[0108] In some embodiments, based on the correspondence between different position attributes and different component types in the drawing type, determining the target component corresponding to the drawing line may exemplarily include:

[0109] When the drawing type is a drawer and the location attribute is inside the frame model of the home model, the target component is determined to be a drawer.

[0110] It should be noted that the above is only an exemplary description, and there may be other corresponding relationships, which are not limited in the embodiments of the present disclosure.

[0111] In some embodiments, based on the correspondence between different direction attributes and position attributes and different component types in the drawing type, determining the target component corresponding to the drawing line may exemplarily include:

[0112] When the drawing type is cabinet panel, the direction attribute is horizontal line, and the position attribute is inside the frame model of the home model, the target component is determined to be the shelf.

[0113] When the drawing type is a cabinet panel, the direction attribute is a horizontal line, and the position attribute is the facade of a frame model of a home model, the distance between the drawing line and the top and bottom surfaces of the frame model can be calculated. When it is determined that the distance between the drawing line and the top surface is closer than the distance to the bottom surface, the target component is determined to be the top panel; when it is determined that the distance between the drawing line and the top surface is farther than the distance to the bottom surface, the target component is determined to be the bottom panel.

[0114] When the drawing type is cabinet panel, the direction attribute is vertical line, and the location attribute is inside the frame model of the home model, the target component is determined to be the middle vertical board, which can be understood as the longitudinal partition in the cabinet.

[0115] When the drawing type is a cabinet panel, the direction attribute is a vertical line, and the position attribute is the facade of a frame model of a home model, the distance between the drawing line and the left and right sides of the frame model can be calculated. When it is determined that the distance between the drawing line and the right side is closer than the distance to the left side, the target component is determined to be the right panel; when it is determined that the distance between the drawing line and the right side is farther than the distance to the left side, the target component is determined to be the left panel.

[0116] It should be noted that the above description is only for illustrative purposes, and there may be other corresponding relationships, which are not limited in the embodiments of the present disclosure.

[0117] In the disclosed embodiment, the starting point and the end point of the operation trajectory are extracted and mapped to obtain an accurate drawing line, and then based on the direction attribute and / or position attribute of the drawing line combined with the correspondence between different component types in the drawing type, an accurate target component is obtained. In addition, considering the errors in the user's drawing process, the positional relationship between the component and the framework model can be automatically adjusted based on the projection of the drawing line and the framework model, avoiding the tedious steps of manual recalculation and adjustment by the user, so that the user can complete the component addition process more quickly. Therefore, on the basis of facilitating user operation, the accuracy of the component installation into the framework model can also be taken into account.

[0118] In some embodiments, the target component is installed into the framework model with reference to the structural process requirements of the target component, which can be implemented as follows:

[0119] Step A1, projecting the panels in the frame model that are perpendicular to the drawing plane onto the drawing plane to obtain a home mapping plane.

[0120] The framework model here may exemplarily be a framework model initially set by the user, or may be a home model in which the user has placed at least one component.

[0121] like Fig. 9As shown, when the drawing plane is a front view, the frame model is projected onto the drawing plane, and the resulting home mapping plane is a rectangular frame.

[0122] Step A2: project the drawing line onto the home mapping plane to determine at least one target sub-component into which the target component is divided by the home mapping plane.

[0123] In some embodiments, when the location attribute of the drawn line is inside the framework model of the home model and there is no intersection with the home mapping plane, the number of target components is determined to be one.

[0124] Specific as Fig. 9 As shown, if there is no intersection between the projection of the drawn line and the projection of the framework model, the number of target subcomponents is determined to be one.

[0125] In some embodiments, when the location attribute of the drawn line is inside the framework model of the home model and there is an intersection with the home mapping plane, the number of target components is determined to be multiple.

[0126] Specific as Fig.10 As shown, the drawn line intersects with the middle vertical board of the home model and is divided into two target subcomponents, which are located on the left and right sides of the middle vertical board respectively.

[0127] Step A3: Install at least one target subassembly into the framework model with reference to the corresponding structural process requirements.

[0128] In the disclosed embodiment, the structural condition of the framework model is taken into consideration, and the drawing lines obtained in a user-visualized manner are combined so that the user can see what he gets, and the free placement of components is realized, making the components more adaptable. In addition, each component has corresponding structural process requirements, and the components are placed based on the corresponding structural process requirements, so that the components are closer to the user's expectations.

[0129] In some embodiments, when the target component is a closing strip, the target component is installed into the frame model with reference to the structural process requirements of the target component, which can be implemented as follows:

[0130] Step B1, determining the center position based on the starting point and the ending point of the operation trajectory.

[0131] During implementation, the center coordinates of the starting point and the end point can be taken and the center coordinates can be determined as the center position. For example, the coordinates of the starting point and the end point on the x-axis are added and then the average is taken as the x-axis coordinate of the center position, and the coordinates of other coordinate axes are determined in the same way to finally obtain the coordinates of the center position.

[0132] Step B2: based on the center position, select the board surface to be adsorbed from the framework model.

[0133] Among them, the distance between the center position and each component in the framework model can be calculated, and the component closest to it is determined as the board to be adsorbed. Among them, the distance between the center position and the center point of each component can be calculated, and the distance between the vertices can also be calculated. It should be noted that the method for calculating the position of each component must be the same. For example, the distance between the center position and the upper left vertex of each component can be calculated, and the embodiments of the present disclosure are not limited to this.

[0134] Step B3, determining the size coordinates of the target component based on the vertex coordinates of the board surface to be adsorbed.

[0135] In some embodiments, when the reference information is the vertex coordinates of each face, determining the size coordinates of the target component in the direction of the second coordinate axis based on the reference information, wherein the second coordinate axis is at least one of the x-axis, the y-axis, and the z-axis, can be implemented as follows:

[0136] Step B31, when the structural process requirements require that the preset distance of the target component is less than or equal to the default value, the candidate coordinates are determined as the size coordinates of the target component in the direction of the second coordinate axis, wherein the preset distance is the distance between the target component and the candidate coordinates, and the candidate coordinates are the coordinates of the reference information on the second coordinate axis.

[0137] Among them, the width of the closing strip can be customized.

[0138] The default value may be 0.

[0139] When implemented, the directions of the x, y, and z axes are as follows Fig.11 As shown, when the closing strip is the left closing strip, the board to be adsorbed is the left board. In this visualization interface, the visualized part of the target component is the front surface, and the visualized part of the left board is also the front surface. When the front surface of the target component and the front surface of the left board are required to be in the same plane. For example, the width of the front surface of the left board is n, and the height is m, then the coordinates of O1 and O2 are (-n, 0, m), (-n, 0, 0), as shown in FIG. Fig.11 The upper right corner and lower right corner of the target component are O1 and O2, and their vertex coordinates are (-n, 0, m) and (-n, 0, 0). Assuming that the custom width of the closing strip is r, the vertex coordinates of the upper left corner O4 and the lower left corner O3 of the target component are (-nr, 0, m) and (-nr, 0, 0), respectively, and the size information of the front surface of the target component is obtained. When the thickness of the custom closing strip is h, the coordinates of the four vertices O1', O2', O3', and O4' on the back surface of the target component are ( Fig.11The vertex coordinates of the front and rear surfaces are (-n, h, m), (-n, h, 0), (-nr, h, 0), and (-nr, h, m). By combining the vertex coordinates of the front and rear surfaces, the size coordinates of the target component can be obtained.

[0140] It should be noted that n, m, r, and h are all numbers greater than or equal to 0.

[0141] Step B32, when the preset distance of the target component is required to be a specified distance in the structural process requirements, the coordinates of the candidate coordinates at the specified distance are determined as the size coordinates of the target component in the direction of the second coordinate axis.

[0142] For example, if the specified distance is 20 mm, Fig.11 For example, the target component is the left closing strip, and the board to be adsorbed is the left board. Then the distance between the target component and the left board needs to be 20mm.

[0143] It should be noted that the aforementioned numerical values ​​are only used for illustrative purposes and are not limited to the embodiments of the present disclosure.

[0144] In the embodiment of the present disclosure, whether there is a requirement for a preset distance of the target component in the structural process requirements can be determined by combining the vertex coordinates of the plate surface to be adsorbed, and this method ensures accuracy while being simple to operate.

[0145] Step B4, filling the target component into the framework model based on the size coordinates.

[0146] In the disclosed embodiment, the board surface to be adsorbed is first screened based on the drawn lines, and then the size coordinates of the target component are determined based on the vertex coordinates of the board surface to be adsorbed. Based on this method, a high degree of adaptability between the target component and the framework model can be achieved.

[0147] In some embodiments, when the target component is a cabinet component other than a closing strip, the target component is installed into the frame model with reference to the structural process requirements of the target component, which can be implemented as follows:

[0148] Step C1, determining the center position based on the starting point and the ending point of the operation trajectory.

[0149] The method of determining the center position has been described above, and the embodiments of the present disclosure will not be described in detail here.

[0150] In step C2, the target space is filtered out from the framework model based on the center position.

[0151] During implementation, searches are performed from the center position in six directions (positive x-axis, negative x-axis, positive y-axis, negative y-axis, positive z-axis, negative z-axis), and when boundaries are found, the target space consisting of the six boundaries is determined. Fig.12 As shown in the figure, the upper part of the frame model where the line is drawn is the target space.

[0152] Step C3, determining the vertex coordinates of each face in the target space.

[0153] Step C4, determining the size coordinates of the target component based on the vertex coordinates of each face.

[0154] In some embodiments, when the reference information is the vertex coordinates of the board to be adsorbed, the size coordinates of the target component in the direction of the second coordinate axis are determined based on the reference information, wherein the second coordinate axis is at least one of the x-axis, the y-axis, and the z-axis, which can be implemented as follows:

[0155] Step C41, when the structural process requirements require that the preset distance of the target component is less than or equal to the default value, the candidate coordinates are determined as the size coordinates of the target component in the direction of the second coordinate axis, wherein the preset distance is the distance between the target component and the candidate coordinates, and the candidate coordinates are the coordinates of the reference information on the second coordinate axis.

[0156] When implemented, the directions of the x, y, and z axes are as follows Fig.12 As shown, when the target component is a layer board, the thickness of the layer board can be customized by the user. If the user does not customize it, the thickness can be determined as the default thickness. An exemplary target thickness is 18 mm. Specifically, the center position determined based on the operation trajectory can be determined as the height of the center point of the layer board, and the z-axis coordinate of the layer board can be obtained by moving the center position determined based on the operation trajectory on the z-axis to obtain the coordinates of the layer board on the z-axis. Exemplarily, the center position determined based on the operation trajectory is amm, and the thickness of the layer board is 18mm, then the coordinates of the upper surface of the target component in the z-axis direction are (a+9) mm, and the coordinates of the lower surface in the z-axis direction are (a-9) mm. In the x-axis direction and the y-axis direction, the coordinates of the top plate or the bottom plate can be determined as the coordinates of the layer board in the x-axis direction and the y-axis direction. Exemplarily, the coordinates of the upper surface of the base plate are A1 (0, 0, 0), A2 (0, b, 0), A3 (c, b, 0), and A4 (c, 0, 0). Therefore, the coordinates of the upper surface of the target component can be, in clockwise order, (0, 0, a+9), (0, b, a+9), (c, b, a+9), (c, 0, a+9), and the same is true for the lower surface. Therefore, the size information of the target component is obtained.

[0157] Among them, a, b, and c are all numbers greater than or equal to 0.

[0158] Step C42, when the preset distance of the target component is required to be a specified distance in the structural process requirements, the coordinates of the candidate coordinates that are the specified distance are determined as the size coordinates of the target component in the direction of the second coordinate axis.

[0159] During implementation, taking the drawer as the target component as an example, when the structural process requirements require that the preset distance of the target component be a specified distance, since the height of the drawer is preset, except for the coordinate axis where the drawer is located, the coordinates in the directions of other coordinate axes need to be away from the corresponding surface in the target space by a specified distance. If there are no other requirements, the coordinate point where the drawer is at a specified distance from the left and right panels can be determined as the size coordinate.

[0160] In the embodiment of the present disclosure, whether there is a requirement for a preset distance of the target component in the structural process requirements can be determined by combining the vertex coordinates of each face in the target space to determine the size coordinates of the target type. This method is simple to operate and ensures accuracy.

[0161] Step C5, filling the target component into the framework model based on the size coordinates.

[0162] In the disclosed embodiment, a target space is obtained by screening based on the center position of a drawn line, so that the target component is fixed within the target space, thereby reducing the calculation range and improving the fit between the target component and the framework.

[0163] In addition, after the user completes the placement of the target component, the user can also modify the component by dragging the component to make the target component closer to the user's expectations.

[0164] In order to facilitate understanding of the method for generating a home model proposed in the embodiment of the present disclosure, the overall flow chart of the method is as follows: Fig.13 As shown, specifically including:

[0176] 3. Improve design efficiency:

[0177] A more intuitive and faster interaction method is achieved, allowing users to complete the component adding process more quickly. In addition, the system can automatically adjust the position and size of components according to the gesture drawing process, avoiding the tedious steps of users needing to manually recalculate and adjust.

[0178] 4. Reduce errors:

[0179] Since users draw directly through gestures, errors caused by human factors can be reduced and the accuracy and consistency of design results can be improved.
