DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solutions and advantages of this specification more clear, the technical solutions of this specification will be clearly and completely described below in combination with the specific embodiments of this specification and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of this specification, not all of the embodiments. Based on the embodiments in this specification, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0019] Geometric structures play an extremely important role in real life. They not only help us understand and describe the world, but are also widely used in various practical engineering, design and scientific research, such as architectural design, mechanical engineering, electronic technology, biomedicine, etc. However, traditional design methods are often limited by the designer's experience and personal perspective, especially in the field of 3D printing technology, where designers still face great challenges when designing geometric structures. For example, in the field of 3D printing technology, designers usually design porous structures by combining multiple geometric structures. However, porous structures usually have complex geometric shapes and contain a large number of tiny holes or channels. Traditional tools often take a lot of time and effort to create and edit such complex geometric structures. In addition, highly accurate models and a large amount of computing resources are required to simulate the behavior of porous materials, such as the flow of fluids through porous media and heat conduction. Traditional finite element analysis (FEA) or other numerical simulation methods may have difficulty in effectively handling such complex geometric details. Therefore, a method that uses algorithms and automated processes to explore the design possibilities of multiple geometric structures, namely generative design, has gradually become an important method for designing complex geometric structures.

[0020] With the development of computer technology, Large Language Model (LLM) has been widely used in various fields, and due to its advantages in logical reasoning, it has gradually become an important tool in generative design. However, the current LLM is more inclined to the processing of natural language, so when generating geometric structures through LLM, the generated geometric structures need to be evaluated to ensure that the generated geometric structures meet the requirements.

[0021] However, currently, the evaluation of geometric structures generated by LLM often relies on manual review, which is not only time-consuming but also likely to introduce errors. Based on this, this specification provides a geometric structure evaluation method, device, storage medium, and electronic device.

[0022] It should be noted that in one or more embodiments of the present specification, the geometric structure evaluation method described can be applied to the testing of various geometric structures, without limiting whether the geometric structure to be evaluated is generated by LLM, and can also be used to evaluate geometric structures generated by other means, such as artificially generated geometric structures.

[0023] In addition, since the generation goals of geometric structures used in different fields are different, and some of them are even very different, in order to facilitate the description of the geometric structure evaluation method, this application specification will use the geometric structure as a porous structure as an example to describe the evaluation method.

[0024] The technical solutions provided by the embodiments of this specification are described in detail below in conjunction with the accompanying drawings.

[0025] Figure 1 A schematic flow chart of a geometric structure evaluation method provided in an embodiment of this specification includes the following steps: S100: Acquire parameters of a geometric structure to be evaluated and a generation target of the geometric structure, wherein the generation target includes generation conditions to be met in order to generate the geometric structure to be evaluated.

[0026] In one or more embodiments of the present specification, there is no restriction on which device the geometric structure evaluation method is specifically executed by, for example, a mobile terminal and a server, etc. However, since subsequent steps involve model training, script calling and other steps, these steps are generally executed by a server. Therefore, this specification also uses the server executing the geometric structure evaluation method as an example for description, wherein the server can be a single device, or composed of multiple devices, for example, a distributed server, a cloud service server, etc., and this specification does not impose any restrictions on this.

[0027] In order to evaluate the generated geometric structure, the server may first obtain the geometric structure to be evaluated and the generation target of the geometric structure to be evaluated, so as to subsequently evaluate whether the geometric structure to be evaluated meets the generation target.

[0028] Specifically, the server first obtains the parameters of the geometric structure to be evaluated, and obtains the generation target corresponding to the generation of the geometric structure to be evaluated. It should be noted that in one or more embodiments of the present specification, the specific shape of the geometric structure to be evaluated is not limited, such as Figure 2 As shown, Figure 2 The schematic diagram of the geometric structure provided for the embodiment of this specification, the geometric structure to be tested can be a conventional geometric structure, such as a cube, a cone, etc., or it can be a combination of multiple geometric structures, or it can be a porous structure, which can be set according to actual needs, and this specification does not limit this. Furthermore, this specification does not limit the generation target. The generation target includes the generation conditions to be met for generating the geometric structure to be evaluated. For example, the generation target is to generate a porous structure with a volume fraction of 0.2, which is connected and has 8 rods. The generation conditions included therein include at least, such as the volume fraction of the geometric structure is 0.2, it is porous and connected, and the porous structure contains 8 rods. It should be noted that there are many generation conditions that can be set, and this specification does not list them one by one. You can set them according to actual needs.

[0029] In one or more embodiments of the present specification, there is no limitation on the specific method used by the server to obtain the geometric structure to be evaluated. It may be to respond to an evaluation instruction and randomly select one from the generated geometric structures as the geometric structure to be evaluated, or it may be to pre-select several from various generation conditions as generation targets according to requirements, and then generate the corresponding geometric structure to be evaluated according to the generation target. The present specification does not impose any limitation on this, and it can be set according to actual needs.

[0030] Furthermore, the specific content of the parameters of the obtained geometric structure is not limited, and can be determined according to the expression method of the geometric structure. For example, if the geometric structure is expressed by an implicit function, the parameters of the geometric structure at least include the implicit function expression of the geometric structure and each weight. If the geometric structure is expressed by a binary tree, the parameters of the geometric structure at least include the parameters of the nodes and edges of the geometric structure. If the geometric structure is expressed by an image, the parameters of the geometric structure at least include the coordinates of the key points of the geometric structure. Since there are many ways to express geometric structures, in one or more embodiments of the present application specification, the specific content of the parameters of the geometric structure obtained by the server is not limited, and can be set according to actual needs.

[0031] In addition, in one or more embodiments of the present specification, there is no limitation on the specific method used by the server to obtain the generated target. It can be determined according to the actual method of obtaining the geometric structure to be evaluated, or it can be set according to actual needs.

[0032] S102: calling a target script from a preset evaluation script library, and using the target script to determine geometric properties of the geometric structure to be evaluated according to parameters of the geometric structure to be evaluated.

[0033] Since the generation target of the geometric structure to be evaluated includes at least one generation condition, in order to evaluate the geometric structure to be evaluated, the server can generate a corresponding evaluation script for each generation condition in advance and build an evaluation script library. Then, when evaluating the geometric structure, the server calls the corresponding evaluation script according to each generation condition included in the generation target of the geometric structure to be evaluated, thereby determining the properties of the geometric structure to be evaluated.

[0034] Specifically, the server calls each evaluation script one by one from a preset evaluation script library as a target script, so that the target script determines the properties of the geometric structure to be evaluated according to the parameters of the geometric structure to be evaluated.

[0035] It should be noted that in one or more embodiments of the present specification, each evaluation script in the evaluation script library is a code logic used to determine the attributes of the geometric parameters to be evaluated based on the parameters of the geometric structure to be evaluated, such as an evaluation script for determining the volume fraction of a geometric structure, an evaluation script for determining the connectivity of a porous structure, etc., which are generally generated in accordance with various generation conditions.

[0036] In addition, the attributes of the geometric structure described in this application refer to the geometric attributes of the geometric structure, and each attribute corresponds to at least one matching generation condition, for example, the volume fraction of the geometric structure, the relationship between the bounding box of the geometric structure and the cylinder of the geometric structure, etc.

[0037] S104: Determine whether the geometric attribute matches the generation target. If so, determine that the geometric structure to be evaluated meets the generation target. If not, determine that the geometric structure to be evaluated does not meet the generation target.

[0038] After determining the properties of the geometric structure to be evaluated, the server can determine whether the geometric structure to be evaluated meets the generation target based on the properties of the geometric structure to be evaluated and the generation target, thereby determining whether the geometric structure to be evaluated can be used in practical applications.

[0039] Specifically, after determining the attributes of the geometric structure to be evaluated, the server matches the attributes of the geometric structure to be evaluated with each generation condition in the generation target. When all the generation conditions and attributes are matched successfully, it means that the geometric structure to be evaluated meets the generation target and can be used in production practice. When at least one generation condition fails to match the attribute, it means that the geometric structure does not meet the generation target and cannot be used in production practice, and the model for generating the geometric structure needs to be adjusted.

[0040] based on Figure 1 In the geometric structure evaluation method shown, the parameters of the geometric structure to be evaluated and the generation target of the geometric structure are obtained, and according to the generation target of the geometric structure, the target script for evaluating the geometric structure is called and run from the pre-set evaluation script to determine the properties of the geometric structure. Then, according to the matching relationship between the properties of the geometric structure and the generation target, it is determined whether the geometric structure meets the generation target.

[0041] In the above method, an automated and unified evaluation of the generated geometric structure is achieved through a pre-set evaluation script, which reduces manual participation and improves the evaluation efficiency and accuracy of the geometric structure.

[0042] In step S100, in addition to obtaining the geometric parameters to be evaluated according to the evaluation instruction, the server may also configure a large model for generating a geometric structure, and then evaluate the geometric structure generated by the large model.

[0043] Specifically, the generation target of the geometric structure to be generated is obtained, and then the generation target is input into the trained large model, so that the large model generates the geometric structure to be evaluated according to the generation target, and then the parameters of the geometric structure to be evaluated are determined according to the geometric structure to be evaluated. The generation target of the geometric structure to be generated can also be a test data set determined according to user needs, and then the large model generates the geometric structure according to the test data set. Then, the semantic extraction of the test data set is performed through the large language model to identify the generation conditions of the geometric structure, so as to judge whether the geometric structure meets the user needs according to the generation conditions.

[0044] Furthermore, in step S102, in order to further improve the evaluation efficiency and reduce the consumption of computing resources, the server may first perform keyword detection on the generation target of the geometric structure to be evaluated, and then match the detected keywords with each evaluation script in the preset evaluation script library to determine at least one evaluation script, and then use at least one evaluation script as a target script and call them in parallel. Of course, they can also be called one by one in sequence. The server can also combine the determined evaluation scripts into a target script for the geometric structure to be evaluated.

[0045] In addition, if the geometric structure to be evaluated is a porous structure, due to the complex structure of the porous structure, the server will generally evaluate the geometric properties of the porous structure based on the relevant characteristics of the porous structure in order to better evaluate the porous structure, which mainly includes the number and volume fraction of rods in the porous structure, the effectiveness, symmetry, connectivity, and conformality of the structure. Based on this, in one or more embodiments of this specification, an evaluation process for the evaluation script of the above-mentioned geometric properties is also provided.

[0046] If the generation target of the porous structure includes that the geometric structure has a cylinders, the server can call an evaluation script for identifying the number of rods, and determine the number of cylinders therein based on the parameters of the porous structure through the evaluation script.

[0047] If the generation target of the porous structure includes the volume fraction of the geometric structure as b, the server can call an evaluation script for calculating the volume fraction of the porous structure, and determine the theoretical minimum circumscribed cube of the porous structure, that is, the volume of the bounding box, according to the parameters of the porous structure through the evaluation script, and then determine the volume of each cylinder in the porous structure, the radius r of the bottom surface of each cylinder, and the number of intersections D between each cylinder, so as to determine the volume of the pores in the porous structure as the sum of the volumes of each cylinder minus , and finally the volume fraction of the porous structure is determined as the ratio of the volume of the pores to the volume of the bounding box.

[0048] In addition, the bounding box generally refers to the theoretical minimum circumscribed cube of the generated porous structure, so each cylinder in the generated porous structure should be within the bounding box, and the bounding box is determined before the porous structure is generated, so when testing the generated porous structure, it is also possible to first determine whether the porous structure has structural validity, that is, whether each cylinder is within the theoretical bounding box. Furthermore, the server can call an evaluation script for determining the structural validity of the porous structure, input the parameters of the geometric structure to be evaluated into the evaluation script, and determine the bounding box of the porous structure and each cylinder in the porous structure. Then, it is determined whether each cylinder is within the bounding box. If so, it means that the porous structure has structural validity, and if not, it means that the porous structure does not have structural validity. Of course, when determining whether the porous structure has structural validity, it is also possible to determine whether the coordinates of each point on each cylinder are within the bounding box to determine whether the porous structure has structural validity.

[0049] If the generation target of the porous structure includes that the geometric structure to be evaluated has symmetry, the server can call an evaluation script for determining the symmetry of the porous structure, and then input the parameters of the geometric structure to be evaluated into the evaluation script to determine the bounding box of the porous structure and each cylinder in the porous structure. With the center of the porous structure as the origin and the direction parallel to the edge of the bounding box, a coordinate system is established to determine whether each cylinder is centered at the origin and is mirror-symmetric along each axis of the coordinate system. If so, it means that the porous structure has symmetry, and if not, it means that the porous structure does not have symmetry.

[0050] In addition, the new coordinates of the symmetric points of the two endpoints in the cylinder can be calculated with the body center as the center: symmetric about the x-axis, the x coordinate changes, the y and z coordinates remain unchanged, symmetric about the y-axis, the y coordinate changes, the x and z coordinates remain unchanged; symmetric about the z-axis, the z coordinate changes, the x and y coordinates remain unchanged. And judge whether the symmetry point exists in the porous structure. If not, it means that the structure is not symmetrical on the axis. Then for each cylinder, the symmetry points of the two endpoints of the cylinder are calculated according to the above process to form a new symmetrical cylinder, and judge whether the newly generated symmetrical cylinder exists in the porous structure. If not, it means that the structure is not symmetrical on the axis. It should be noted that the same two endpoints connected in different orders represent the same cylinder. Among them, the above endpoints can refer to any point on the bottom surface of the cylinder.

[0051] If the generation target of the porous structure includes that the geometric structure to be evaluated has connectivity, the server may call an evaluation script for determining the connectivity of the porous structure, and then input the parameters of the geometric structure to be evaluated into the evaluation script to determine each cylinder in the porous structure. Then, for each cylinder, it is determined whether the cylinder intersects with at least one other cylinder. If so, it means that the porous structure has connectivity, and if not, it means that the porous structure does not have connectivity.

[0052] In addition, each cylinder can be simplified into a line segment, and the connectivity of the porous structure can be determined by judging whether the line segments intersect. The depth-first search or breadth-first search in graph theory can also be used to traverse the graph, that is, if starting from any line segment, all other line segments can be traversed, the structure is connected. If starting from any line segment, all other line segments can be traversed, the structure is connected.

[0053] It should be noted that in one or more embodiments of the present specification, the order in which the server calls the scripts is not limited and can be determined randomly or in a preset order, and can be set according to actual needs.

[0054] Since there are many methods that can be adopted, the above is only one embodiment provided in this specification, and the evaluation script can be set according to actual needs. For example, if the generated geometric structure is used to form a circuit board, the evaluation script may also include circuit conductivity simulation test, etc.

[0055] Furthermore, in the geometric structure evaluation method of one or more embodiments of the present application, the properties between two or more geometric structures can also be evaluated. For example, in the field of three-dimensional printing, the generated porous structures should also have commonality, that is, the two porous structures have the same nodes and edges on the six faces of the cubic unit, i.e., the bounding box. Then, the server can determine which cylinders' edges and bottoms in the two porous structures are exactly on the six faces of the cube when determining that both porous structures have structural validity, and then compare whether the cylinders' edges and bottoms of the two structures coincide on the six faces. If they completely coincide, it means that commonality is satisfied; otherwise, it is not commonality.

[0056] In addition, it should be noted that in one or more embodiments of the present specification, the above-mentioned evaluation method can be specifically used for the evaluation of geometric structures, and can also be performed by the detection layer in the geometric structure generation model, such as Figure 3 As shown, Figure 3 A schematic diagram of a geometric structure generation and evaluation process provided in an embodiment of this specification, wherein the user inputs a generation target into the geometric structure generation model, so that the geometric structure generation model generates a geometric structure, then performs semantic extraction on the generation target, determines the generation conditions of the geometric structure, determines a test script according to each generation condition, determines whether the geometric structure meets the generation condition, and outputs the judgment result. If the generation condition is met, the geometric structure is output; if the generation condition is not met, the geometric structure is regenerated according to the generation target, and the above steps are repeated until a preset number of geometric structures that meet the generation target are generated or at least one stop condition such as a preset time length is reached, the generation of the geometric structure is stopped.

[0057] Based on the same idea of ​​a geometric structure evaluation method provided in one or more embodiments of this specification, this specification also provides a corresponding evaluation device, such as Figure 4 shown.

[0058] Figure 4 A schematic diagram of an evaluation device provided in this specification specifically includes: An acquisition module 400 is used to acquire parameters of a geometric structure to be evaluated and a generation target of the geometric structure, wherein the generation target includes generation conditions to be satisfied for generating the geometric structure to be evaluated; The determination module 401 is used to call a target script from a preset evaluation script library, and use the target script to determine the geometric properties of the geometric structure to be evaluated according to the parameters of the geometric structure to be evaluated; The judgment module 402 is used to judge whether the geometric attribute matches the generation target. If so, it is determined that the geometric structure to be evaluated meets the generation target. If not, it is determined that the geometric structure to be evaluated does not meet the generation target.

[0059] Optionally, the device further includes a generation module 403 for acquiring a generation target of the geometric structure to be generated; inputting the generation target into the trained large model, so that the large model generates the geometric structure to be evaluated according to the generation target.

[0060] Optionally, the determination module 401 is used to extract keywords from the generation conditions through a preset large model to determine at least one target keyword; based on the matching relationship between the at least one target keyword and each evaluation script in a preset evaluation script library, determine at least one target script and call it.

[0061] Optionally, the geometric structure to be evaluated is a porous structure, and the generated target includes that the geometric structure to be evaluated has structural validity; a determination module 401 is used to input the parameters of the geometric structure to be evaluated into the target script, determine the bounding box of the porous structure and the cylinders within the porous structure, wherein the bounding box is the theoretical minimum circumscribed cube of the porous structure; determine whether the cylinders are all within the bounding box, and if so, determine that the porous structure has structural validity, and if not, determine that the porous structure does not have structural validity.

[0062] Optionally, the geometric structure to be evaluated is a porous structure, and the generated target includes that the geometric structure to be evaluated has symmetry; a determination module 401 is used to input the parameters of the geometric structure to be evaluated into the target script, determine the bounding box of the porous structure and the cylinders within the porous structure, wherein the bounding box is the theoretical minimum circumscribed cube of the porous structure; establish a coordinate system with the center of the porous structure as the origin and in a direction parallel to the edge of the bounding box; determine whether the cylinders are mirror-symmetric along the axes of the coordinate system with the origin as the center, and if so, determine that the porous structure has symmetry, and if not, determine that the porous structure does not have symmetry.

[0063] Optionally, the geometric structure to be evaluated is a porous structure, and the generated target includes that the geometric structure to be evaluated has connectivity; a determination module 401 is used to input the parameters of the geometric structure to be evaluated into the target script to determine each cylinder in the porous structure; for each cylinder, determine whether the cylinder intersects with at least one other cylinder; if so, determine that the porous structure has connectivity; if not, determine that the porous structure does not have connectivity.

[0064] Optionally, the judgment module 402 is used to traverse the various generation conditions and the geometric attributes, and respectively determine the geometric attributes that satisfy the various generation conditions; when the various generation conditions are satisfied, it is determined that the geometric attributes match the generation target; when there are unsatisfied generation conditions, it is determined that the geometric attributes do not match the generation target.

[0065] This specification also provides a computer-readable storage medium, which stores a computer program, which can be used to execute the above Figure 1 A geometric structure evaluation method is provided.

[0066] This manual also provides Figure 5 The one shown corresponds to Figure 1 Schematic diagram of the structure of an electronic device. Figure 5 As shown, at the hardware level, the electronic device includes a processor, an internal bus, a network interface, a memory, and a non-volatile memory, and may also include other hardware required for the business. The processor reads the corresponding computer program from the non-volatile memory into the memory and then runs it to achieve the above Figure 1 An evaluation method described.

[0067] Of course, in addition to software implementation, this specification does not exclude other implementation methods, such as logic devices or a combination of software and hardware, etc., that is to say, the executor of the following processing flow is not limited to each logic unit, but can also be hardware or logic devices.

[0068] In the 1990s, it was very clear whether the improvement of a technology was hardware improvement (for example, improvement of the circuit structure of diodes, transistors, switches, etc.) or software improvement (improvement of the method flow). However, with the development of technology, many improvements of the method flow today can be regarded as direct improvements of the hardware circuit structure. Designers almost always obtain the corresponding hardware circuit structure by programming the improved method flow into the hardware circuit. Therefore, it cannot be said that the improvement of a method flow cannot be implemented with hardware entity modules. For example, a programmable logic device (PLD) (such as a field programmable gate array (FPGA)) is such an integrated circuit whose logical function is determined by the user's programming of the device. Designers can "integrate" a digital system on a PLD by programming it themselves, without having to ask chip manufacturers to design and make dedicated integrated circuit chips. Moreover, nowadays, instead of manually making integrated circuit chips, this kind of programming is mostly implemented by "logic compiler" software, which is similar to the software compiler used when developing and writing programs, and the original code before compilation must also be written in a specific programming language, which is called hardware description language (HDL). There is not only one kind of HDL, but many kinds, such as ABEL (Advanced Boolean Expression Language), AHDL (Altera Hardware Description Language), Confluence, CUPL (Cornell University Programming Language), HDCal, JHDL (Java Hardware Description Language), Lava, Lola, MyHDL, PALASM, RHDL (Ruby Hardware Description Language), etc. The most commonly used ones are VHDL (Very-High-Speed ​​Integrated Circuit Hardware Description Language) and Verilog.
