Description

Technical Field

[0001] The present disclosure relates to the field of image processing, and in particular to a method, device and electronic device for generating a virtual model. Background Art

[0002] With the development of computer hardware, the artistic effects that can be displayed in games are getting better and better. However, in terms of physical effect generation, it is often difficult to achieve a high degree of realism. Taking the generation of concrete crushing effect as an example, the concrete model is usually cut first, and the normal of the cut surface is sampled. Then, the pre-designed steel bar model is directly inserted into the cut concrete model along the sampling point to generate a concrete crushing model. However, this generation process does not conform to the science of building materials, nor does it conform to the performance process of concrete when crushed in real scenes. The physical effect of concrete crushing that can be displayed is less realistic.

[0003] To address the above-mentioned problems, no effective solutions have been proposed so far. Summary of the Invention

[0022] In one possible implementation, the inventors, after practicing and carefully studying methods commonly used in the field of image processing, have discovered that the fragmentation generation process does not conform to real-world scenarios, resulting in poor realism in the fragmentation effect. Therefore, the game scene used in the embodiments of the present disclosure can be a game scene with an object fragmentation model, and the game type targeted is generally a 3D (three-dimensional) game. A method for generating a virtual model is proposed. The technical concept employed comprises obtaining a first virtual model corresponding to a concrete structure and a spline curve corresponding to a support structure within the concrete structure; cutting the first sub-model and the second sub-model to obtain a first cut model and a second cut model; generating a second virtual model corresponding to the support structure based on the first cut model and the spline curve; and combining the second virtual model, the first cut model, and the second cut model to ensure that the generated model conforms to building materials science, making the entire fragmentation process more consistent with the concrete fragmentation behavior in real-world scenarios, thereby further improving the realism of the resulting model fragmentation effect, thereby resolving the technical problem of poor realism in the fragmentation effect of generated virtual models in the related art.

Figure 1 FIG. 1 is a hardware structure diagram of a mobile terminal for a method of generating a virtual model according to an embodiment of the present disclosure. Figure 1 As shown, the mobile terminal may include one or more ( Figure 1Only one is shown in the figure) a processor 102 (the processor 102 may include but is not limited to a central processing unit (CPU), a graphics processing unit (GPU), a digital signal processing (DSP) chip, a microprocessor (MCU), a field-programmable logic device (FPGA), a neural network processor (NPU), a tensor processing unit (TPU), an artificial intelligence (AI) type processor, etc.) and a memory 104 for storing data.

Figure 1 FIG. 1 is a hardware structure diagram of a mobile terminal for a method of generating a virtual model according to an embodiment of the present disclosure. Figure 1 As shown, the mobile terminal may include one or more ( Figure 1 The mobile terminal may further include a processor 102 (only one of which is shown) and a memory 104 for storing data. Optionally, the mobile terminal may further include a transmission device 106, an input / output device 108, and a display device 110.

[0027] Those skilled in the art will understand that Figure 1 The structure shown is only for illustration and does not limit the structure of the mobile terminal. Figure 1 More or fewer components than shown, or with Figure 1 Different configurations shown.

[0028] According to one embodiment of the present disclosure, an embodiment of a method for generating a virtual model is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0029] Currently, the concrete crushing model is generated by directly inserting a pre-designed steel bar model on the sampled normal line after sampling the normal line of the concrete model cutting surface. However, the realism of the crushing effect is not high. Figure 2 is a schematic diagram of a traditional concrete crushing model according to one embodiment of the present disclosure, as shown in FIG. Figure 2 As shown in the figure, the crushing boundary of the concrete model is distorted, and the steel bar model on the crushing surface is disordered, and the steel bars do not have the same directionality, which is inconsistent with the actual building materials science. In addition, since concrete has a process and type when it is crushed, Figure 2 The crushing model generated in the experiment does not have this feature and does not conform to the physical crushing process. This also results in the final concrete crushing model not conforming to the real scene and the crushing effect is poorly realistic.

[0030] In a possible implementation, to address the above-mentioned problem, an embodiment of the present disclosure provides a method for generating a virtual model, providing a graphical user interface through a terminal device, wherein the terminal device can be the local terminal device mentioned above, or the client device in the cloud interaction system mentioned above. Figure 3 is a flow chart of a method for generating a virtual model according to one embodiment of the present disclosure, as shown in FIG. Figure 3 As shown, the method includes the following steps:

[0031] Step S302: Acquire a first virtual model corresponding to the concrete structure and a spline curve corresponding to the supporting structure inside the concrete structure.

[0032] The first virtual model includes: a first sub-model and a second sub-model. The first sub-model is used to represent the sub-model corresponding to the support structure, and the second sub-model is used to represent the sub-models in the first virtual model except the first sub-model.

[0033] The first virtual model mentioned above may refer to an overall virtual model corresponding to concrete, such as a virtual model corresponding to a wall.

[0034] The first sub-model described above may refer to a sub-model corresponding to a supporting structure within the concrete. For example, to ensure the rigidity and toughness of concrete, reinforcement bars and other supporting structures are often added to the concrete. Therefore, in an alternative embodiment of this embodiment, the entire region corresponding to the reinforcement bars within the concrete may be used as the supporting structure to generate the first sub-model. The region corresponding to the first sub-model includes both the reinforcement bar region and the cement region, not just the independent region corresponding to the reinforcement bars themselves.

[0035] It should be noted that the first virtual model is only a concrete model, which does not include a steel bar model for maintaining structural stability. The combination of the steel bar model and the concrete model will be specifically embodied below.

[0036] The second sub-model mentioned above may refer to the model corresponding to other areas in the entire concrete except the supporting structure.

[0037] The above-mentioned spline curve may refer to the curve corresponding to the supporting structure inside the concrete. In the supporting structure, an object with high rigidity and toughness is usually required to ensure the stability of the entire structure, such as the steel bars in the concrete. Since the supporting structure refers to the entire area inside the concrete, the spline curve here may refer to the shape curve corresponding to the object used to maintain the stability of the supporting structure, such as the shape curve of the steel bars in the concrete.

[0038] In an optional solution of this embodiment, in order to ensure that the generated concrete model conforms to the actual building materials science and improve the realism of the concrete model, before generating the concrete crushing model, virtual models corresponding to different parts of the concrete can be first produced according to the characteristics of the concrete material in the real scene, such as a first virtual model corresponding to the entire concrete, a first sub-model corresponding to the supporting structure where the steel bars in the concrete are located, and a second sub-model corresponding to the remaining areas except the supporting structure.

[0039] At the same time, in order to avoid the appearance of a messy steel bar model in the final broken model that does not conform to the real scene, it is also possible to formulate a shape curve that the steel bar model can present in the concrete model when generating the first virtual model, that is, the above-mentioned spline curve, and simulate the position of the steel bar in the concrete model based on the spline curve, thereby ensuring that the first virtual model produced is more in line with the real scene, avoiding the messy steel bar effect in the final presentation, and improving the user's viewing experience.

[0040] Figure 4 is a schematic diagram of a first virtual model according to one embodiment of the present disclosure, such as Figure 4As shown, the entire first virtual model can be composed of two parts. The first part is the support structure, such as the area where the steel bars are located in the concrete. This corresponds to the first sub-model, namely the area corresponding to the dashed rectangle. The dotted line within the dashed line represents the aforementioned spline curve. The second part is the area excluding the support structure, corresponding to the second sub-model, namely the area separated by the dashed rectangle and the solid rectangle. In this embodiment, before generating the crushing model, a specific concrete model is first generated based on the concrete material structure given in building materials science. This ensures that the subsequent crushing process of the concrete conforms to the actual crushing process, thereby improving the realism of the final crushing model.

[0041] Step 304 : Cut the first sub-model and the second sub-model to obtain a first cut model and a second cut model.

[0042] The first cutting model includes a plurality of first cutting blocks, and the second cutting model includes a plurality of second cutting blocks.

[0043] The first cutting blocks mentioned above may refer to the fragments corresponding to the supporting structure generated when the concrete model is crushed; the second cutting blocks mentioned above may refer to the fragments outside the supporting structure generated when the concrete model is crushed.

[0044] After the concrete model is produced, it can be cut according to the crushing effect of concrete in real scenes.

[0045] In an optional solution of this embodiment, since the supporting structure inside the concrete will also be broken and fractured when the concrete is broken, when the concrete model is cut, the above-mentioned first sub-model and second sub-model can be further cut accordingly. Since the rigidity and toughness of cement and steel bars in real scenarios are different, the rigidity and toughness of the supporting structure inside the concrete are higher. Therefore, when cutting the model, different cutting parameters can be used to cut the first sub-model and the second sub-model respectively. For example, a smaller cutting range can be set for the second sub-model, and a larger cutting range can be set for the first sub-model.

[0046] Optionally, the first sub-model and the second sub-model are cut to obtain the first cut model and the second cut model, including: determining the distance between the supporting structure and the outer surface of the concrete structure; dividing the first virtual model based on the distance to obtain the first sub-model and the second sub-model; cutting the first sub-model based on the first cutting parameter to obtain the first cut model; cutting the second sub-model based on the second cutting parameter to obtain the second cut model.

[0047] Since in real-world scenarios, when concrete materials are made, supporting structures such as steel bars are wrapped in cement, in the concrete model, the internal supporting structures will be at a certain distance from the outer surface of the concrete model. Furthermore, due to the support of supporting structures such as steel bars, the rigidity and toughness of the concrete area near the steel bars are higher than other areas. In other words, based on the distance between the above-mentioned supporting structures and the outer surface of the model, the concrete model can be divided into two parts: the outer model and the inner model, that is, the first model corresponding to the aforementioned supporting structure and the second model corresponding to the remaining areas. It should be noted that this distance can be designed based on actual conditions and material requirements, and is not specifically limited.

[0048] In an optional solution of this embodiment, before generating the concrete model, a distance a may be preset as the distance between the above-mentioned support structure and the outer surface of the concrete, and then a concrete model with a double-layer structure may be generated based on the distance a.

[0049] In an optional solution of this embodiment, when a concrete model with an inner and outer double-layer structure is generated according to a preset distance a, the outer surface of the model can be first disturbed using the distance a to obtain a smaller inner layer structure, and then a Boolean operation is further performed based on the disturbance and outer surface information, such as size, shape, etc., to obtain an inner layer structure corresponding to the outer surface of the concrete.

[0050] In an alternative solution to this embodiment, as described above, different segmentation parameters can be set for the first sub-model corresponding to the support structure and the second sub-model corresponding to the remaining area, respectively, to simulate the various fragments produced when concrete is crushed in real-world scenarios. The specific segmentation parameters can be designed based on actual conditions and are not specifically limited.

[0051] Step S306: Generate a second virtual model corresponding to the support structure based on the first cutting model and the spline curve.

[0052] The second virtual model is located outside the first cutting model.

[0053] The second virtual model mentioned above may refer to a steel bar model used to improve the stability of the concrete model.

[0054] Since the above-mentioned first cutting model corresponds to the model of the internal support structure of concrete, and the stability of the support structure is provided by steel bars, in an optional scheme of this embodiment, the required steel bar model, i.e. the above-mentioned second virtual model, can be generated based on the first cutting model and the corresponding spline curve on the model.

[0055] When concrete is crushed, the cement surrounding the rebar will fall off due to inertia and gravity, exposing the rebar outside the cement. This results in the rebar model being partially inside and partially outside the first cut model. To improve generation efficiency, in an optional solution of this embodiment, only the rebar portion outside the first cut model can be considered for generation based on the spline curve. In other words, the second virtual model can be located outside the first cut model.

[0056] Optionally, based on the first cutting model and the spline curve, a second virtual model corresponding to the support structure is generated, including: scaling the first cutting model to obtain a scaled model; cropping the spline curve based on the scaled model to obtain a cropped spline curve, wherein the cropped spline curve is located outside the scaled model; and generating a second virtual model based on the cropped spline curve.

[0057] In order to further improve the realism of the generated crushing model, taking into account that concrete will be lost during crushing, resulting in the crushed part being smaller than before crushing, in an optional scheme of this embodiment, before generating the second virtual model, the above-mentioned first cutting model can be first scaled to obtain a scaled model, and then the spline curve corresponding to the scaled model can be trimmed and adjusted to determine the spline curve outside the scaled model. Finally, the steel bar model is generated according to the trimmed and adjusted spline curve, that is, the above-mentioned second virtual model, to obtain a crushing effect that is more in line with the real scene.

[0058] It should be noted that in order to reflect that part of the steel bars will be exposed when broken, the clipped spline curve needs to be outside the first cut model after scaling.

[0059] Figure 5 is a schematic diagram showing a model scaling adjustment result according to one embodiment of the present disclosure, such as Figure 5 As shown in the figure, from left to right are: the first cutting model, the scaled first cutting model, the scaled model including the spline curve, and the spline curve obtained by cutting and adjusting the scaled model.

[0060] In an optional solution of this embodiment, after obtaining the final trimmed and adjusted spline curve, a steel bar model can be generated according to information such as the shape and size of the spline curve.

[0061] Step S308: Combine the second virtual model, the first cutting model, and the second cutting model to generate a target virtual model.

[0062] The target virtual model mentioned above may refer to the finally generated broken concrete-steel model.

[0063] In an optional solution of this embodiment, after all required second virtual models, first cutting models, and second cutting models are generated, the three can be combined to obtain a target virtual model.

[0064] Optionally, the second virtual model, the first cutting model and the second cutting model are combined to generate a target virtual model, including: determining the distance between the second virtual model and each first cutting block; determining the target cutting block corresponding to the second virtual model from multiple first cutting blocks based on the distance; combining the second virtual model with the target cutting block to generate a combined model; combining the second cutting model with the combined model to generate the target virtual model.

[0065] In order to ensure the integrity of the generated steel bar model and improve the efficiency of generating the steel bar model, the steel bar model can be generated directly according to the spline curve on the surface of the first cutting model instead of directly. However, since there are multiple first cutting blocks in the first cutting model, combination errors may occur when combining the second virtual model and the first cutting model. Therefore, in an optional scheme of this embodiment, each time a second virtual model is generated, the target cutting block corresponding to the second virtual model can be determined according to the distance between it and each first cutting block and the volume of each first cutting block, thereby realizing the combination of the second virtual model and the first cutting model. Finally, the combined model is combined with the second cutting model for a second time to obtain the above-mentioned target virtual model.

[0066] In an optional solution of this embodiment, when performing the above-mentioned model combination, Boolean operations can be used to improve the accuracy of the combination.

[0067] In an optional solution of this embodiment, the distance between the second virtual model and the first cutting block may be a vertical distance between the midpoint of the second virtual model and the surface of the first cutting block.

[0068] Optionally, determining a target cutting block corresponding to the second virtual model from a plurality of first cutting blocks based on distance includes: determining the volumes of the plurality of first cutting blocks; determining weight values ​​corresponding to the plurality of first cutting blocks based on distance and volume; and determining the first cutting block corresponding to the maximum weight value among the weight values ​​corresponding to the plurality of first cutting blocks as the target cutting block.

[0069] The above-mentioned weight value may refer to the attraction weight of the first cutting block to the second virtual model. In an optional scheme of this embodiment, as shown above, the attraction weight of each first cutting block to the second virtual model may be determined based on the distance between the second virtual model and each first cutting block, and the volume of each first cutting block. The larger the attraction weight, the greater the possibility that the first cutting block is the target cutting block of the second virtual model. Therefore, after calculating the attraction weights of all first cutting blocks to the second virtual model, the first cutting block with the largest weight value may be used as the target cutting block.

[0070] Optionally, based on the distance and volume, the weight values ​​corresponding to the multiple first cutting blocks are determined, including: performing a square operation on the distance to obtain a first operation result; performing a power operation on the volume to obtain a second operation result; obtaining the ratio of the second operation result to the first operation result to obtain the weight values ​​corresponding to the multiple first cutting blocks.

[0071] Specifically, the formula for determining the above weight value can be as follows:

[0072]

[0073] Among them, W represents the attraction weight of each first cutting block to the second virtual model; S represents the distance from the first cutting block to the second virtual model; K represents the concrete coefficient, which is a constant and can be determined according to actual conditions, for example, according to the viscosity of concrete; V represents the volume of the fragments of the first cutting block.

[0074] Figure 6 is a schematic diagram of a crushing model according to one embodiment of the present disclosure, such as Figure 6 As shown, the structure of the entire broken model is clear, and the steel bar model in the concrete is not messy or irregular, showing high realism.

[0075] In at least some embodiments of the present disclosure, a method is adopted in which a first virtual model corresponding to a concrete structure and a spline curve corresponding to a supporting structure inside the concrete structure are obtained; the first sub-model and the second sub-model are cut to obtain a first cut model and a second cut model; based on the first cut model and the spline curve, a second virtual model corresponding to the supporting structure is generated; and the second virtual model, the first cut model and the second cut model are combined to generate a target virtual model. First, an overall model including multiple structural sub-models is generated according to the concrete structure to ensure that the generated model conforms to building materials science and improves the realism of the model. Then, the overall model is cut according to the crushing effect. At the same time, the sub-models inside the overall model are adjusted and combined according to the distortion deformation occurring when the model is broken, so that the entire crushing process is more consistent with the crushing performance of concrete in real scenes, thereby further improving the realism of the final model crushing effect, thereby solving the technical problem of poor realism of the crushing effect of generating virtual models in related technologies.

[0076] Optionally, the spline curve is cropped based on the scaled model to obtain a cropped spline curve, including: performing a cross-detection on the spline curve and the scaled model to determine a target line segment in the spline curve located inside the scaled model; and removing the target line segment from the spline curve to obtain the cropped spline curve.

[0077] In an optional solution of this embodiment, before clipping the spline curve in the scaled first cutting model, an intersection check may be performed on the spline curve and the model to determine the portion of the spline curve to be clipped.

[0078] Generally, in order to ensure that the generated steel bar model can have a high degree of fit with the first cutting module, the spline curve part inside the scaled model can be determined as the part to be cut, and then the part to be cut can be removed from the spline curve to obtain the above-mentioned cut spline curve.

[0079] Figure 7 is a schematic diagram of a spline curve cutting process according to one embodiment of the present disclosure, such as Figure 7 As shown in the figure, from left to right are the scaled model and the model of the intersection of the spline curve, the cropped spline curve, and the steel bar model generated according to the spline curve.

[0080] Optionally, the spline curve and the scaled model are cross-checked to determine the target line segment in the spline curve located inside the scaled model, including: obtaining the starting point and the ending point of each line segment in the spline curve; determining the starting position of the starting point in the scaled model, and the ending position of the ending point in the scaled model; and determining the target line segment in the spline curve based on the starting position and the ending position.

[0081] When determining the target portion to be cropped in the spline curve, that is, the above-mentioned target line segment, we can first determine whether there is a spline curve that is inferior to the first cutting model after scaling the first cutting model. If there is an intersection, we can further determine the portion to be cropped in the intersecting spline curve based on the starting and ending points of the intersecting spline curve and the position of the scaled model.

[0082] In an optional solution of this embodiment, since the corresponding spline curve will also be cut when the first sub-model is cut, when determining the starting and ending points of the spline curve, it is necessary to obtain the starting and ending points corresponding to each cut line segment in the spline curve to avoid misjudgment.

[0083] Optionally, based on the starting position and the ending position, a target line segment in the spline curve is determined, including: determining the length of each line segment based on the starting position and the ending position; filtering a preset line segment from the spline curve based on the length of each line segment, wherein the length of the preset line segment is greater than or equal to a preset length; and determining a target line segment among the preset line segments.

[0084] In an optional solution of this embodiment, when the part of the spline curve to be cropped can be further determined based on the starting and ending points of each line segment in the curve, the part to be cropped in the curve can be screened by the length.

[0085] In an optional solution of this embodiment, a screening length threshold can be set. When the length of a line segment is greater than the length threshold, it can be considered that the line segment needs to be clipped and can be determined as the part to be clipped, that is, the target line segment mentioned above.

[0086] Through the description of the above implementation methods, those skilled in the art can clearly understand that the method according to the above embodiment can be implemented by means of software plus the necessary general hardware platform, and of course it can also be implemented by hardware, but in many cases the former is a better implementation method. Based on this understanding, the technical solution of the present disclosure, or the part that contributes to the prior art, can be embodied in the form of a software product, which is stored in a storage medium (such as ROM / RAM, magnetic disk, optical disk), and includes a number of instructions for enabling a terminal device (which can be a mobile phone, computer, server, or network device, etc.) to execute the methods of the various embodiments of the present disclosure.
