Description

Technical Field

[0001] This invention relates to the field of landscape engineering design technology, and in particular to an automatic design method, equipment and medium for rockery. Background Technology

[0002] Artificial hills serve multiple landscaping functions, such as forming the main scenery or topographical framework of a garden, dividing and organizing garden space, arranging courtyards, revetments, slopes, and retaining walls, and setting up natural-style flower beds. They are an important element of garden design, combining with garden architecture, paths, grounds, and plants to create varied scenery, thereby reducing artificiality and adding natural charm, allowing garden architecture to blend into the natural landscape—a characteristic of Chinese natural landscape gardens. The quality of the artificial hill construction directly affects the overall landscape of the garden.

[0003] The design of artificial mountains must highlight the landscape features while harmonizing with the surrounding scenery, thus often resulting in diverse and flexible shapes. Taking stone artificial mountains as an example, the stones used are all natural materials of varying shapes. Determining whether the stones on site meet the requirements for stacking stones relies on the on-site selection by the craftsman, requiring on-site hoisting to observe the shape and structure of the stones, and pre-installation testing. For large stone artificial mountains, it is often difficult to achieve both the designed effect and structural safety, leading to multiple rework sessions, which is time-consuming and labor-intensive. Multiple hoisting operations increase the workload of on-site stone stacking, and since some large stones weigh several tons, frequent hoisting also poses certain safety hazards.

[0004] In existing technologies, a method is used to create a solid model of the stone using 3D lasers, assemble the proportionally scaled 3D printed model for design, and then create a solid model of the proportionally scaled model again to form the final design scheme, generating design and construction drawings. However, this method is mainly design-oriented and requires two point cloud solid modeling processes and a manual 3D printing assembly process, which is cumbersome. Moreover, the generated construction drawings include plan views, elevation views, section views, and detailed views, which are not convenient for guiding on-site workers to accurately construct and hoist the stone, and cannot ensure that the artificial rockery is formed in one go during construction. Summary of the Invention

[0005] The technical problem to be solved by this invention is that the existing automatic design method for artificial rockery is not convenient for guiding on-site workers to accurately construct and hoist the rockery. This invention provides an automatic design method for artificial rockery that can automatically and quickly generate accurate three-dimensional stacking design schemes for artificial rockery, and generate precise construction guidance documents based on these schemes. This facilitates the guidance of on-site workers to accurately construct and hoist the rockery, ensuring that the artificial rockery is formed in one go during the construction process.

[0016] S14, Based on the acquired point cloud data, identify the coding information of the stone raw material.

[0017] Furthermore, specifically, step S2, which involves constructing the three-dimensional model of the stone, includes the following steps:

[0018] S21, use the Poisson distribution algorithm to reconstruct the surface of the point cloud data to obtain the reconstructed surface;

[0019] S22, the reconstructed surface is smoothed and optimized to obtain the three-dimensional model of the stone.

[0020] Furthermore, specifically, step S4 includes the following steps:

[0021] S41: Import all the described three-dimensional stone models into the three-dimensional software;

[0022] S42: Calculate the volume of each of the three-dimensional stone models, and group all the three-dimensional stone models into large, medium, and small groups based on the calculated volume;

[0023] S43: Obtain the large-scale drawing of the rockery, and establish an overall model of the rockery based on the feature points of the large-scale drawing of the rockery, and calculate the volume V of the overall model of the rockery;

[0025] S45: The grouped 3D stone models are proportionally placed into the simulated stacking container, and the 3D stone models are simulated and stacked based on their gravity characteristics to form a stacked rockery model. The coordinates of the center of gravity of the stacked rockery model and its total volume V' are calculated, and the density P of the stacked rockery model is calculated. i The calculation formula is: P i =V / V';

[0026] S46: Repeat step S45 to obtain the currently stacked rockery model, obtain the centroid coordinates and total volume of the currently stacked rockery model, and calculate the density P of the currently stacked rockery model. i+1 ;

[0027] S47: Adjust the density P of the currently piled-up rockery model. i+1 The density P of the previously piled-up rockery model i Compare;

[0028] If P i >P i+1 Then update the centroid coordinates and orientation information of the three-dimensional stone model in the stacked rockery model;

[0029] Conversely, clear the currently accumulated rockery model;

[0030] S48: Repeat S45~S47 until the number of simulations is greater than m, to obtain the final stacked rockery model.

[0031] Furthermore, specifically, step S5 includes the following steps:

[0035] Furthermore, specifically, in step S44, the bottom surface of the simulated stacking container is determined based on the bottom surface of the overall rockery model. After the bottom surface of the simulated stacking container is determined, it extends upward along the edge to form the simulated stacking container. The height of the simulated stacking container is 2-3 times the maximum height of the overall rockery model. The bottom surface of the overall rockery model is a polygon.

[0037] Furthermore, specifically, in step S45, the grouped three-dimensional stone models are proportionally placed into the simulated stacking container. After simulating the stacking of the three-dimensional stone models based on their gravity characteristics, they are matched with the overall rockery model. Stone models whose center of gravity coordinates are outside the overall rockery model are deleted. Gravity simulation and matching deletion are repeated multiple times until no stone model has a center of gravity coordinate outside the overall rockery model, thus completing the stacked rockery model.

[0038] Alternatively, in step S45, the grouped three-dimensional stone models are proportionally placed into the simulated stacking container, and after simulating the stacking of the three-dimensional stone models based on their gravity characteristics, the maximum displacement of each three-dimensional stone model is less than 3mm when it is in the simulated stacking container under the action of gravity, thus completing the stacked rockery model.

The method automatically and quickly generates an accurate three-dimensional stacking design plan for the artificial rockery, and generates an accurate construction plan accordingly, which facilitates the guidance of on-site workers for precise construction and hoisting, ensuring that the artificial rockery is formed in one go during the construction process, saving construction time and ensuring that the mountain construction achieves the design effect.

[0060] Example 1

[0061] This application provides an automatic design method for artificial rockeries, such as... Figure 1 As shown, the design method includes:

[0062] S1: Collect descriptive parameter data of stone raw materials, preprocess the descriptive parameter data to obtain preprocessed point cloud data, detect the point cloud data, obtain the coding information of stone raw materials, and save it.

[0063] In this embodiment, such as Figure 2 As shown, step S1 specifically includes the following steps:

[0064] S11. The stone raw material is scanned from all angles using a data acquisition device to obtain descriptive parameter data. For example, during transport and loading, the stone raw material is scanned 360° using the acquisition device, which may include, but is not limited to, lidar or image acquisition devices. Each stone raw material has a unique code on its surface, ensuring its uniqueness and facilitating the construction of a 3D model in subsequent steps.

[0065] S12, the description parameter data is cropped and filtered using a bilateral filter. Due to factors such as the acquisition accuracy of the acquisition equipment and the operator's experience and environment, the description parameter data contains irrelevant areas and a large number of scattered points and isolated points. By cropping and filtering the description parameter data, the processed description parameter data achieves the purpose of preserving edges, smoothing noise reduction, and removing obvious outliers, which facilitates the subsequent construction of the stone 3D model.

[0066] S13 optimizes the filtered description parameter data using a voxel filter. The optimized data is point cloud data. The voxel filter is used to downsample the filtered description parameter data, reducing the computational load of surface reconstruction in the subsequent construction of the stone 3D model, improving computational efficiency, and removing noise and outliers.

[0067] S14. Based on the acquired point cloud data, identify the coding information of the stone raw materials.

[0068] S2: Construct a 3D model of the stone based on the point cloud data obtained in S1, save it, and bind the 3D model of the stone with the coded information.

[0069] In this embodiment, step S2, constructing the three-dimensional model of the stone, specifically includes the following steps:

[0070] S21. The Poisson distribution algorithm is used to reconstruct the surface of the point cloud data to obtain the reconstructed surface.

[0071] S22, the reconstructed surface is smoothed and optimized to obtain a three-dimensional stone model. Further, the Laplacian mesh smoothing algorithm is used to smooth and optimize the reconstructed surface.

[0072] S3: Using steps S1 and S2, obtain and save the coding information and three-dimensional models of all stone raw materials. The coding information and the three-dimensional models of the stone are in one-to-one correspondence. The coding information and the three-dimensional models of all stone raw materials are stored in the database.

[0073] S4 imports all the 3D stone models into the 3D software, establishes a simulated stacking container based on the detailed drawing of the rockery, and automatically simulates the stacking of the 3D stone models in the simulated stacking container to form a stacked rockery model.

[0074] It should be noted that during the simulated stacking, the stone 3D model is combined with the gravity characteristics of the stone 3D model for simulation stacking. The stone 3D model will be balanced and adjusted under the action of simulated gravity and the interaction of the surrounding stone 3D models to ensure that the stacked stone rockery can be stable.

[0075] In this embodiment, such as Figure 3-9 As shown, step S4 specifically includes the following steps:

[0076] S41: Import all stone 3D models into the 3D software.

[0077] S42: Calculate the volume v of each stone 3D model. i Based on the calculated volume, all three-dimensional stone models are grouped into large, medium, and small groups.

[0078] Specifically, calculate the minimum cube bounding box (the bounding box is a directed bounding box) of the 3D stone model, obtain the coordinates of its 8 corner points, and calculate the volume V. bi Divide each of the three sides of the bounding box into N parts, resulting in N³ cubes. Dividing each side into 30 parts yields 27,000 cubes. Calculate the number of cubes *m* whose boundary points are all inside the 3D model and the number of cubes *n* whose boundary points are all outside the 3D model. Approximate the cubes on the model boundaries as half the size of the cubes. The volume of the stone 3D model can be approximated as *v*. i =V bi / N3×(n+(N3-mn) / 2).

[0079] S43: Obtain a large-scale drawing of the rockery, and establish an overall model of the rockery based on the feature points of the large-scale drawing of the rockery, and calculate the volume V of the overall model of the rockery; specifically, obtain feature points through image processing, establish an overall model of the rockery that can represent the large-scale drawing of the rockery based on the feature points, and calculate the volume V of the overall model of the rockery using the volume calculation method for the three-dimensional model of the stone in step S42.

[0080] In some specific implementations, feature points can be manually selected to establish an overall model of the rockery that can represent a large-scale drawing of the rockery, thereby improving the accuracy of the overall rockery model.

[0081] S44: Create a simulated stacking container.

[0082] Furthermore, in step S44, the bottom surface of the simulated stacking container is determined based on the bottom surface of the overall rockery model. After the bottom surface of the simulated stacking container is determined, it extends upwards along the edge to form the simulated stacking container. The height of the simulated stacking container is 2-3 times the maximum height of the overall rockery model, and the bottom surface of the overall rockery model is polygonal. Further, the minimum inscribed circle is calculated based on the bottom surface of the overall rockery model. The minimum inscribed circle is used as the bottom surface of the simulated stacking container, forming a cylindrical shape. This minimal stacking container facilitates the stacking of the 3D stone model in subsequent steps, improving the speed of simulated stacking.

[0083] S45: The grouped 3D stone models are proportionally placed into a simulated stacking container. Based on the gravity characteristics of the 3D stone models, the models are simulated and stacked to form a stacked rockery model. The coordinates of the center of gravity and the total volume V' of the stacked rockery model are calculated. The density P of the stacked rockery model is also calculated. i The calculation formula is: P i =V / V'.

[0084] Furthermore, in step S45, the grouped 3D stone models are proportionally placed into the simulated stacking container. After simulating the stacking of the 3D stone models based on their gravity characteristics, the models are placed back into the simulated stacking container, allowing them to accumulate and stabilize under gravity. A maximum displacement of less than 3mm within the simulated stacking container indicates stability. This prevents excessive simulation time and ensures controllable errors in actual stacking, further improving the speed of simulated stacking.

[0085] Alternatively, in step S45, the grouped 3D stone models are proportionally placed into the simulated stacking container. After simulating the stacking of the 3D stone rockery model based on the gravity characteristics of the 3D stone models, the model is matched with the overall rockery model. Stone 3D models whose center of gravity coordinates are outside the overall rockery model are deleted. Gravity simulation and matching deletion are repeated multiple times until no stone 3D model has a center of gravity coordinate outside the overall rockery model, so that the final stacked rockery model and the large-scale rockery drawing are roughly the same.

[0086] S46: Repeat step S45 to obtain the currently piled-up rockery model, obtain the centroid coordinates and total volume of the currently piled-up rockery model, and calculate the density P of the currently piled-up rockery model. i+1 .

[0087] S47: Adjust the density P of the currently piled-up rockery model. i+1The density P of the previously piled-up rockery model i In comparison, the greater the density, the more stable the stacked stone rockery model; if P i >P i+1 Then, update the centroid coordinates and orientation information of the 3D stone model in the stacked rockery model. The centroid coordinates of the 3D stone model are the centroid coordinates of the smallest cubic bounding box of the stone. The orientation information refers to the angle between the center of the bounding box and a certain corner point vector and the coordinate axis. The angle includes α, β, and γ, such as... Figure 9 As shown; conversely, if P i ≤P i+1 Then clear the currently accumulated rockery model.

[0088] S48: Repeat S45~S47 until the number of simulations is greater than m to obtain the final stacked rockery model. Further, the value of m is preferably 500. The more simulations, the higher the accuracy of the final stacked rockery model.

[0089] Steps S41 to S48 can automatically and quickly generate an accurate three-dimensional model of the rockery, facilitating the formation of precise construction plans in subsequent steps.

[0090] S5, derive the construction plan for the rockery based on the stacked rockery model.

[0091] In this embodiment, step S5 specifically includes the following steps:

[0092] S51. Based on the final stacked rockery model, establish a three-dimensional coordinate system with the center point of the simulated stacking container as the origin.

[0093] S52, from the center point outwards and from bottom to top, statistically analyze the three-dimensional stone models in the stacked rockery model to obtain the encoding information of all the three-dimensional stone models used in the stacked rockery model.

[0094] S53, based on the encoded information, exports the center of gravity coordinates and attitude information of the corresponding three-dimensional stone model, determines the top and bottom surfaces of the hoisting and the hoisting method, and generates a list of construction procedures and mechanical configuration requirements according to the construction sequence.

[0095] This invention provides an automatic design method for artificial rockeries. It constructs a three-dimensional model of the stone by collecting descriptive parameter data of the raw stone material. The three-dimensional model is then imported into 3D software to simulate the stacking of the artificial rockery, resulting in a stacked model. Based on this model, a construction plan is developed. For actual construction, an automated and rapid, precise three-dimensional stacking design scheme for the artificial rockery is generated, along with a precise construction plan. Construction is then carried out according to this plan, facilitating precise construction and hoisting by on-site workers. This ensures the artificial rockery is formed in one go during construction, saving construction time and guaranteeing that the rockery achieves the designed effect.
