Description

Technical Field

[0001] The present invention relates to the field of modeling technology, and in particular to a three-dimensional design model optimization method, device, electronic equipment and storage medium. Background Art

[0002] With the continuous advancement of construction engineering and manufacturing technology, three-dimensional design models have been widely used in construction scenarios. However, three-dimensional design model files are usually generated based on standard geometric structures and design data, and do not fully consider the actual needs of specific construction scenarios, so they cannot be directly used in actual construction scenarios. These actual needs may include space limitations at the construction site, installation locations of actual equipment, material selection, load requirements, and environmental conditions. For example, in actual construction, the spatial data of the construction scene (such as the size of the site, the specific location of equipment installation, the geometry of the building, etc.) may differ from the theoretical model in the design stage. Therefore, in the construction scenario, the three-dimensional design model file needs to be adjusted according to the actual data requirements to ensure that it can be implemented efficiently and safely in actual construction.

[0003] However, when adjusting the 3D design model, geometric interference problems between the various parts in the model often occur. Specifically, when the geometric size, volume or position of certain parts are adjusted according to construction requirements, these adjustments may cause spatial interference between the parts and other adjacent parts. For example, when a part is enlarged or moved, it may overlap or contact with other parts, causing assembly interference. If these interference problems are not discovered and properly handled in time, they may have many adverse effects on the construction process, such as installation obstacles, construction delays, material waste, and even affect the safety and accuracy of construction. Summary of the invention

[0004] The embodiments of the present invention provide a 3D design model optimization method, device, electronic device and storage medium. By implementing the present invention, the 3D design model file can be adjusted according to actual data requirements to ensure that it can be implemented efficiently and safely in actual construction, thereby ensuring the safety and accuracy of model construction.

[0005] An embodiment of the present invention provides a three-dimensional design model optimization method, comprising:

[0006] Obtain the 3D design model files to be optimized and the actual data requirements of the construction scene.

[0007] Parse the 3D design model file and generate the geometric data of the part.

[0008] According to the actual data requirements of the construction scene, the geometric data of the parts that need to be adjusted are initially adjusted to obtain an adjusted part.

[0009] Repeat the secondary adjustment operation of the parts until all parts in the 3D design model have no spatial interference, and generate an optimized 3D design model.

[0010] The secondary adjustment operation of the parts includes:

[0011] Get the current one-time adjustment part; wherein the initial one-time adjustment part is any one-time adjustment part that has not undergone a second adjustment.

[0013] According to the size of the current one-time adjustment part and the size of the current part to be compared, the sum of the sizes of the current one-time adjustment part and the current part to be compared is calculated.

[0014] If the first distance is smaller than the sum of the sizes, the current part to be compared is added to the interference part set.

[0016] Furthermore, the parsing of the 3D design model file to generate geometric data of the part includes:

[0018] A representation graph is constructed for the plurality of layers to generate a plurality of representation graphs.

[0019] An information matrix of a three-dimensional design model is generated according to the plurality of representation diagrams.

[0020] The information matrix is ​​parsed to generate geometric data of the part.

[0021] Further, the calculating of the first distance between the current first-adjusted part and the current part to be compared according to the coordinates of the current first-adjusted part and the coordinates of the current part to be compared includes:

[0022] According to the coordinates of the current first-adjusted part and the coordinates of the current part to be compared, the Euclidean distance between the current first-adjusted part and the current part to be compared is calculated, and the Euclidean distance is used as the first distance between the current first-adjusted part and the current part to be compared.

[0023] Furthermore, adjusting the volume of the current one-time adjustment part according to the geometric data of all parts in the interfering part set includes:

[0024] For each part in the interference parts set, the corresponding volume adjustment amount is calculated according to the size and volume of the part.

[0025] The adjusted volume is calculated according to the volume adjustment amount and the current volume of the one-time adjustment part; and the volume of the current one-time adjustment part is updated with the adjusted volume.

[0026] Furthermore, after the geometric data of the parts to be adjusted are adjusted for the first time according to the actual data requirements of the construction scene to obtain the first adjusted parts, the following is further included:

[0027] Parse the 3D design model file and generate the material data of the parts.

[0028] According to the actual data requirements of the construction scene, the material data of the parts that need to be adjusted will be adjusted, and the material data of the parts that need to be adjusted will be updated.

[0029] Furthermore, after generating the optimized three-dimensional design model, it also includes:

[0030] Based on the plurality of representation graphs, a topological relationship between the parts is generated.

[0031] The complexity of the three-dimensional design model is calculated and generated according to the number of topological relationships between the parts and the number of parts.

[0032] The output format of the three-dimensional design model file is determined according to whether the complexity is greater than a preset complexity threshold.

[0033] The three-dimensional design model file is output according to the output format.

[0038] The part initial adjustment module is used to perform initial adjustment on the geometric data of the part that needs to be adjusted according to the actual data requirements of the construction scene to obtain a primary adjusted part.

[0039] The model optimization module is used to repeatedly perform the part secondary adjustment operation until all parts in the three-dimensional design model do not interfere with each other in space, and an optimized three-dimensional design model is generated. The part secondary adjustment operation includes: obtaining the current one-time adjustment part. The initial one-time adjustment part is any one-time adjustment part that has not been adjusted twice. According to the coordinates of the current one-time adjustment part and the coordinates of the current part to be compared, the first distance between the current one-time adjustment part and the current part to be compared is calculated. The part to be compared is the remaining parts in the three-dimensional design model except the current one-time adjustment part, and the initial part to be compared is any one-time comparison part that has not been compared. According to the size of the current one-time adjustment part and the size of the current part to be compared, the sum of the sizes between the current one-time adjustment part and the current part to be compared is calculated. If the first distance is less than the sum of the sizes, the current part to be compared is added to the interference part set. It is determined whether the current part to be compared is the last one to be compared that has not been compared in the current one-time adjustment part. If so, the volume of the current one-time adjustment part is adjusted according to the geometric data of all parts in the interference part set, and the geometric data of the current one-time adjustment part is updated. Clear the interference part set, and reselect a first adjustment part that has not been adjusted twice, and update the current first adjustment part.

[0055] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0056] like Figure 1 As shown, an embodiment of the present invention provides a three-dimensional design model optimization method, which at least includes the following steps:

[0057] Step S1: Obtain the 3D design model file to be optimized and the actual data requirements of the construction scene.

[0058] It should be noted here that the 3D design model file is a data file used to store the geometric information, topological structure and related attributes of a 3D object. It is widely used in industrial design, architecture, manufacturing, game development, virtual reality and other fields to represent the 3D shape and structure of an object and support subsequent visualization, analysis, simulation and manufacturing operations.

[0059] 3D design models are usually generated under idealized conditions based on standard geometry and design data, without fully considering the actual needs of specific construction scenarios, and therefore cannot be directly applied to actual construction. In actual construction scenarios, there may be problems such as space constraints, equipment installation locations, material selection, etc. that are different from the design stage. For example, the spatial dimensions of the construction site, the installation location of the equipment, the geometric shape of the building, etc. may deviate from the theoretical model. Therefore, in order to ensure that the model can be executed efficiently and safely in actual construction, the 3D design model file must be adjusted according to the actual data requirements.

[0060] The actual data requirements of the construction scene mainly include spatial data, equipment installation location, material selection, load requirements, environmental conditions and building geometry;

[0061] The spatial data includes the actual size of the construction site, available space, and locations of obstacles.

[0062] The equipment installation location includes information such as the installation location and installation angle of the specific equipment at the construction site.

[0063] The material selection includes the materials actually used and their physical properties (such as density and strength) may be different from those set during design.

[0064] The load requirements include the load and stress requirements of the building structure or equipment in actual use.

[0065] The environmental conditions include environmental factors such as temperature, humidity, wind speed, etc., which will affect the construction plan and material properties.

[0066] The geometric shape of the building, including the actual building form, may differ from the theoretical model and need to be adjusted based on actual on-site data.

[0067] These adjustments based on actual needs ensure the adaptability and reliability of the model in real construction.

[0068] Step S2, parsing the 3D design model file to generate geometric data of the part;

[0069] In a preferred embodiment, the step of parsing the 3D design model file to generate geometric data of the part includes:

[0070] The three-dimensional design model is constructed in layers to generate several layers.

[0071] A representation graph is constructed for the plurality of layers to generate a plurality of representation graphs.

[0072] An information matrix of a three-dimensional design model is generated according to the plurality of representation diagrams.

[0073] The information matrix is ​​parsed to generate geometric data of the part.

[0074] It should be noted that when optimizing a 3D design model file, you first need to construct the model in layers. Layer construction refers to the hierarchical management of the model's assembly information, where the assembly represents a relatively complete component in the model. This hierarchical management can more effectively organize and process the assembly information in the model, facilitating subsequent analysis and adjustment.

[0075] After completing the layer construction, you need to generate a representation diagram of the layer. The representation diagram contains the information of each part in the model, and it intuitively reflects the structure and layout of the parts in the model. Through the representation diagram, you can more clearly view and understand the relationship between the parts in the model, and provide a basis for the acquisition and analysis of geometric data.

[0076] Next, the information matrix of the 3D design model can be obtained through the representation diagram. The information matrix contains the geometric data of each part in the model. By parsing the information matrix, the geometric data of each part in the model can be extracted for evaluating and optimizing the model. The geometric data includes volume, coordinates, and dimensions.

[0077] Step S3: According to the actual data requirements of the construction scene, the geometric data of the parts that need to be adjusted are initially adjusted to obtain the primary adjusted parts.

[0078] Specifically, according to the actual data requirements of the construction scene, the geometric data of the parts that need to be adjusted will be adjusted for the first time, which means that the geometric data of the parts must first be modified in combination with the actual conditions such as the on-site load requirements, environmental conditions, geometric shape space limitations of the building, and equipment installation location. These adjusted geometric data will generate a primary adjustment part. For example, if the space on the construction site is small, the volume or size of the part needs to be reduced;

[0079] In addition, in a preferred embodiment, after the geometric data of the part to be adjusted is initially adjusted according to the actual data requirements of the construction scene to obtain the primary adjusted part, the method further includes:

[0080] Analyze the 3D design model file and generate the material data of the parts;

[0081] According to the actual data requirements of the construction scene, the material data of the parts that need to be adjusted will be adjusted, and the material data of the parts that need to be adjusted will be updated.

[0082] In actual operation, the material selection of certain parts may also be adjusted due to actual environmental conditions (such as temperature, humidity, etc.). The material data of the parts must be modified and updated once to make them more in line with the actual needs of the construction scenario, laying the foundation for further optimization and interference checking.

[0083] Step S4, repeatedly performing the secondary adjustment operation of the parts until all the parts in the three-dimensional design model have no spatial interference, and generating an optimized three-dimensional design model.

[0084] like Figure 2 As shown, the secondary adjustment operation of the parts includes at least the following steps:

[0085] Step S4.1, obtaining the current primary adjustment part, wherein the initial primary adjustment part is any primary adjustment part that has not undergone secondary adjustment;

[0086] Step S4.2: Calculate the first distance between the current once-adjusted part and the current part to be compared according to the coordinates of the current once-adjusted part and the coordinates of the current part to be compared.

[0087] In an optional embodiment, the first distance between the current first adjustment part and the current part to be compared is calculated according to the coordinates of the current first adjustment part and the coordinates of the current part to be compared, including:

[0088] According to the coordinates of the current first-adjusted part and the coordinates of the current part to be compared, the Euclidean distance between the current first-adjusted part and the current part to be compared is calculated, and the Euclidean distance is used as the first distance between the current first-adjusted part and the current part to be compared.

[0089] In a specific implementation, the coordinates of the current one-time adjustment part are {x1, y1, z1}, and the coordinates of the current part to be compared are {x2, y2, z2}. The first distance between the current one-time adjustment part and the current part to be compared is calculated by the following formula:

[0090]

[0091] Wherein, d is the first distance;

[0092] Step S4.3, according to the size of the current once-adjusted part and the size of the current part to be compared, calculate the sum of the sizes between the current once-adjusted part and the current part to be compared.

[0093] The size of the part can be obtained from the geometric data of the part, and the sum of the size of the current once-adjusted part and the size of the current part to be compared is calculated, and the result obtained is the sum of the sizes.

[0094] Step S4.4: If the first distance is smaller than the sum of the sizes, the current part to be compared is added to the interference part set.

[0095] It should be noted here that if the first distance is less than the sum of the sizes, it is considered that there is spatial interference between the current primary adjustment part and the current part to be compared. Spatial interference means that the two parts overlap or are too close in the actual space, which may lead to incorrect installation or operation in actual construction or assembly. Therefore, it is necessary to optimize and adjust these interfering parts.

[0096] In this case, the current part to be compared is first added to the interference part set, which is used to record all parts that interfere with the current part to be compared. Next, the current part to be compared needs to be analyzed and adjusted according to the geometric data of these interfering parts to eliminate the interference.

[0097] Step S4.5, determine whether the current part to be compared is the last unmatched part to be compared of the current one-time adjustment part; if so, adjust the volume of the current one-time adjustment part according to the geometric data of all parts in the interference part set, and update the geometric data of the current one-time adjustment part; clear the interference part set, and reselect a one-time adjustment part that has not been adjusted twice, and update the current one-time adjustment part; if not, select the next unmatched part to be compared of the current one-time adjustment part, and update the current part to be compared.

[0098] In a preferred embodiment, the step of adjusting the volume of the current one-time adjustment part according to the geometric data of all parts in the interfering part set includes:

[0099] For each part in the interference parts set, the corresponding volume adjustment amount is calculated according to the size and volume of the part;

[0100] The adjusted volume is calculated according to the volume adjustment amount and the current volume of the one-time adjustment part; and the volume of the current one-time adjustment part is updated with the adjusted volume.

[0101] Specifically, for each part in the interference parts set, the volume adjustment amount of the part is calculated based on its size and volume. Specifically, the product of the size of each interfering part and the volume adjustment coefficient is calculated to obtain the corresponding product result; the volume of each interfering part is divided by its corresponding product result to generate the corresponding volume adjustment amount; wherein the volume adjustment coefficient can be selected according to the actual situation. This calculation method aims to determine the degree of interference of the part on the current adjustment part through the geometric proportion of the part. In this way, the influence of each interfering part on the adjustment can be reasonably reflected, ensuring that the volume and size differences of each part are taken into account during the adjustment process.

[0102] Next, based on the calculated volume adjustment, the volume of the current one-time adjustment part is optimized and adjusted. Specifically, the volume of the current one-time adjustment part will be recalculated by combining with these volume adjustments to obtain a new volume value. The formula is: the adjusted volume is equal to the initial volume of the current one-time adjustment part minus the sum of the volume adjustments of all interfering parts. This process ensures that the contribution of each interfering part to the volume optimization of the one-time adjustment part is reasonably considered, and the adjusted volume is finally obtained.

[0103] Finally, the geometric data of the current one-time adjustment part is updated using the adjusted volume, and the new volume data is applied to the model to ensure that it no longer interferes with other parts in space. The key to this optimization process is to dynamically adjust the volume and size of the interfering parts to reduce or eliminate spatial conflicts and ensure the rationality and feasibility of the 3D design model. In this way, the optimized parts can better adapt to the actual needs of the construction scene while avoiding assembly problems caused by spatial interference. The optimization process is completed when the volume, coordinates, and sizes of all parts have been adjusted as necessary and there are no longer any spatial conflicts in the model. At this point, an optimized 3D design model that meets the construction needs is generated.

[0104] In a preferred embodiment, after generating the optimized three-dimensional design model, the method further includes:

[0105] Generating a topological relationship between parts according to the plurality of representation graphs;

[0106] Calculating and generating the complexity of the three-dimensional design model according to the number of topological relationships between the parts and the number of parts;

[0107] Determining an output format of the three-dimensional design model file according to whether the complexity is greater than a preset complexity threshold;

[0108] The three-dimensional design model file is output according to the output format.

[0109] In the specific implementation, the topological relationship between parts is constructed based on the generated representation diagrams. The topological relationship reflects the way in which the parts in the 3D design model are connected, adjacent, and interact with each other. These relationships include not only geometric adjacency, but may also involve structural connections or functional dependencies. By analyzing these relationships, the relative positions and functional associations between parts in the model can be clarified, providing a basis for subsequent complexity calculation and optimization.

[0110] Next, based on the topological relationships between the parts, the number of topological relationships of the model is calculated. This number refers to the number of various geometric or structural connections between different parts in the model. The quotient of the number of topological relationships between the parts and the number of parts is calculated as the complexity of the 3D design model. This calculation formula shows that if the number of parts is small but the number of topological relationships is large, the complexity is high; conversely, if the number of parts is large but the topological relationships are simple, the complexity is low.

[0111] According to the calculated complexity, the output format of the 3D design model file is determined. Taking the output gim format as an example, the complexity is compared with the preset complexity threshold. The complexity threshold is a pre-set standard used to measure whether the model has a high complexity. If the complexity of the 3D design model is higher than the threshold, it means that the connection relationship between the parts in the model is complex and may contain more details and precision. Therefore, it is necessary to select a more refined geometric accuracy and attribute fineness for display, and use a higher quality output format to maintain the integrity and accuracy of the model. On the contrary, if the complexity of the model is lower than the threshold, it means that the structure of the model is relatively simple, the connection relationship between the parts is more intuitive, and a simpler surface subdivision display method can be selected. At this time, a relatively lightweight output format can be used to improve efficiency and facilitate subsequent operations.

[0112] This output method based on model complexity ensures that the output of the 3D design model can be dynamically adjusted according to actual needs, which not only guarantees the accuracy of complex geometric structures, but also takes into account the efficiency of model rendering.

[0113] Based on the above method embodiment, the present invention provides a corresponding device embodiment.

[0114] like Figure 3 As shown, an embodiment of the present invention provides a three-dimensional design model optimization device, including: a data acquisition module 101, a model file parsing module 102, a part initial adjustment module 103 and a model optimization module 104;

[0115] The data acquisition module 101 is used to acquire the 3D design model file to be optimized and the actual data requirements of the construction scene.

[0116] The model file parsing module 102 is used to parse the 3D design model file and generate geometric data of the part.

[0117] The part initial adjustment module 103 is used to perform initial adjustment on the geometric data of the part to be adjusted according to the actual data requirements of the construction scene to obtain a primary adjusted part.

[0118] The model optimization module 104 is used to repeatedly perform the part secondary adjustment operation until all parts in the three-dimensional design model do not interfere with each other in space, thereby generating an optimized three-dimensional design model; the part secondary adjustment operation includes: obtaining the current one-time adjustment part; wherein the initial one-time adjustment part is any one-time adjustment part that has not been subjected to secondary adjustment; calculating the first distance between the current one-time adjustment part and the current part to be compared according to the coordinates of the current one-time adjustment part and the coordinates of the current part to be compared; wherein the part to be compared is the remaining parts in the three-dimensional design model except the current one-time adjustment part, and the initial one-time adjustment part is any one-time adjustment part that has not been compared; calculating the first distance between the current one-time adjustment part and the current one-time adjustment part according to the size of the current one-time adjustment part and the current one-time adjustment part; The size of the part to be compared, calculate the sum of the sizes between the current one-time adjustment part and the current part to be compared; if the first distance is less than the sum of the sizes, add the current part to be compared to the interference part set; determine whether the current part to be compared is the last unmatched part to be compared of the current one-time adjustment part; if so, adjust the volume of the current one-time adjustment part according to the geometric data of all parts in the interference part set, and update the geometric data of the current one-time adjustment part; clear the interference part set, and reselect a one-time adjustment part that has not been adjusted twice, and update the current one-time adjustment part; if not, select the next unmatched part to be compared of the current one-time adjustment part, and update the current part to be compared.
