[0057] Embodiment 1:

[0058] This embodiment provides a three-dimensional digital planning and design method. Figure 1 The three-dimensional digital planning and design method of this embodiment includes but is not limited to the following steps:

[0059] S101, obtaining an input planning and design scheme;

[0060] In this embodiment, the planning and design scheme includes non-modeled data information and design modeling data. Among them, the non-modeled data information can be data that expresses the planning implementation form, planning objectives and other planning information of the planning and design scheme in text form, and its form includes but is not limited to text, table, etc. The design modeling data is a specific three-dimensional graphical planning scheme formed by the technicians based on the needs of planning and design.

[0061] In this embodiment, both the non-modeled data information and the design modeling data are input into the system so that the system can form a corresponding three-dimensional digital real-scene image.

[0062] S102, matching a simplified model for a planning and design solution;

[0063] This process can be carried out through a trained deep learning model. It should be noted that the simplified model is a preset model data that has been pre-formed and entered into the system, so there is no need to regenerate the model when inputting the planning and design scheme, and the simplified model is relatively simplified and has a lower model accuracy, occupies fewer resources and has a very fast import speed. Exemplarily, in some applications, the simplified model can use shapes such as regular cubes as the model shape, and configure basic parameter attributes. When matching, a simplified model similar to the design in the planning and design scheme can be quickly matched, for example, a simplified model with similar morphology and attributes can be matched. For attributes such as size and coverage area, the relevant parameters of the simplified model can also be adaptively adjusted.

[0064] This embodiment mainly implements rough deduction through simplified models to conduct preliminary verification of planning and design solutions, and does not pursue overly accurate matching results. Therefore, in practical applications, the deep learning model used is relatively simple, has fast matching efficiency and consumes low computing resources.

[0065] In some embodiments, Figure 2 As shown, the above step S102 specifically includes:

[0066] S1021. Obtaining non-modeled data information of the planning and design scheme;

[0067] S1022, without importing the design modeling data in the planning and design scheme, matching a simplified model from a preset simplified model library according to the description of the non-modeled data information;

[0068] That is, this embodiment uses non-modeled data information to match the simplified model. The non-modeled data information is mainly in text format, has a fast reading speed, occupies a small space, and can be quickly identified and understood. By pre-matching a simplified model using the description of non-modeled data information without importing specific design modeling data, a planning plan can be quickly formed in some implementation processes, thereby using the existing verification function in the system to perform preliminary solution verification. It should be understood that the import referred to here is to load the design modeling data into the three-dimensional real-scene model.

[0069] Of course, in practical applications, designers need to retain the corresponding design data according to the recognition requirements of the deep learning model and form non-modeled data information in a form that can be recognized by the deep learning model.

[0070] S103, integrating the simplified model into the three-dimensional real scene model to generate a planning plan;

[0071] The simplified model consumes relatively few resources and has a fast import speed. It can be quickly integrated into the 3D real scene model to form a planning plan. The planning plan can be understood as the result of the planning and design initially formed according to the planning and design scheme, in which the planning and design parts involved are replaced by the simplified model.

[0072] S104. Conduct design deduction based on planning plan;

[0073] The planning plan is simulated through the three-dimensional real-scene simulation module to verify whether the planning plan meets the expected design objectives and whether there are obvious design conflicts and non-compliance situations.

[0074] S105, comparing the design deduction results with the planning goals, and integrating the design modeling data in the planning design scheme into the three-dimensional real scene model after the comparison results meet expectations;

[0075] In practical applications, the expected situation of the comparison result can be set and configured according to actual needs. That is, this embodiment does not require that the deduction result of the planning plan can fully meet the final design goal of the planning design scheme.

[0076] like Figure 3 As shown, in some embodiments, the step of comparing the design simulation results with the planning goals includes:

[0077] S1051. Forming a degradation target based on the design planning target corresponding to the non-modeled data information;

[0078] It should be understood that since a simplified model is used for deduction, the deduction results are not exactly the same as the actual results. The degradation target formed is specifically used to verify the planning plan that uses a simplified model. In practical applications, the degradation target can be directly formed by relaxing the original design target to a certain extent according to the preset rules. Of course, design requirements such as compliance red lines do not need to be relaxed. In other words, to form a degradation target, it is only necessary to relax at least part of the design planning targets, which does not mean that every design planning target needs to be relaxed.

[0079] S1052. Compare the design simulation result with the degradation target;

[0080] If the design simulation results can meet the requirements of the degradation target, the comparison results can be considered to be in line with expectations.

[0081] S106, comparing the design deduction results with the planning goals, and integrating the design modeling data in the planning design scheme into the three-dimensional real scene model after the comparison results meet expectations;

[0082] It is understandable that the simplified model matched is a model that is relatively close to the parameters of the design in the planning and design scheme. This embodiment performs matching and preliminary design deduction based on the simplified model, which can achieve rapid verification of the overall planning and design scheme without importing a detailed model, discover problems in a timely manner, and reduce unnecessary loss of resources.

[0083] When the comparison results meet expectations, it means that the planning plan has passed the preliminary verification. At this time, the design modeling data in the planning and design plan is integrated into the 3D real-life model for further design and deduction. The use of the planning plan for preliminary verification can ensure the smoothness of subsequent design and deduction, eliminate obvious errors in advance, reduce the waste of resources caused by the need to constantly modify and import the highest-precision design modeling data, and improve design efficiency.

[0084] In some embodiments, see Figure 4 , after comparing the design simulation results with the planning goals, it also includes:

[0085] S201, after the comparison result does not meet the degradation target, output an alarm message;

[0086] The warning information includes but is not limited to reminding designers which designs do not meet the planning goals. Designers can find problems in time and make adjustments and modifications before the high-precision design modeling data is loaded.

[0087] S202: After outputting the alarm information, obtain the command input by the user and perform operations according to the command:

[0088] The operations performed include but are not limited to at least one of the following:

[0089] Operation 1: Re-matching the simplified model based on the planning and design scheme re-input by the user;

[0090] Designers can modify the planning and design schemes that do not meet the objectives based on the warning information. By inputting the modified planning and design schemes and re-matching the simplified model, it is possible to verify again whether the modified planning and design schemes meet expectations.

[0091] Operation 2: modifying the target simplified model in the 3D real scene model to the simplified model specified by the user's instruction according to the user's instruction;

[0092] Designers can also modify the simplified model directly. This usually happens when the designer believes that the matching simplified model is wrong or inaccurate, which leads to inaccurate deduction results. By the designer directly modifying the simplified model, the deduction results may become more accurate.

[0093] Operation 3: Ignore the comparison result and continue with the subsequent steps;

[0094] If the designer believes that the result of the simulation is wrong or the error prompted by the alarm information can be temporarily ignored, an instruction can be issued to ignore the comparison result and continue to execute the subsequent steps. This allows the planning and design to continue to move forward and ensure production efficiency. It is understandable that for the errors prompted by the alarm information, the designer can still make adjustments in the subsequent production design process, and it is possible that the corresponding alarm errors may be eliminated after the actual design modeling data is imported.

[0095] In some embodiments, Figure 5 , after the comparison result does not meet the degradation target, the steps of outputting the alarm information include:

[0096] S2011, displaying the three-dimensional real scene model after integrating into the simplified model;

[0097] This process places a simplified model of the design plan into position.

[0098] S2012, highlighting in a set manner the areas where the comparison results do not meet the degradation target;

[0099] Emphasis display refers to displaying the simplified model or the corresponding area in a different way from other models in the 3D real scene model. For example, the simplified model is displayed as a special color such as red, or the area where the comparison result does not meet the degradation target is marked in red.

[0100] By displaying a three-dimensional real-scene model, designers can locate anomalies more quickly and have a preliminary impression and intuitive judgment of the results of the planning and design scheme.

[0101] It should be noted that the simplified model in this embodiment can be a single model or a composite model. A single model refers to a single type of building or planning area, while a composite model is a collection of multiple buildings or planning areas. In practical applications, a composite model usually ignores the layout of specific buildings or areas, and expresses the properties of these buildings or areas as a whole.

[0102] In some embodiments, matching a simplified model for a planning and design scheme includes: matching a model with the highest degree of fitness from a single model and a composite model. That is, when performing model matching, a simplified model that is closer to the design in the design planning scheme is matched as much as possible. For example, a building complex formed by multiple buildings in the design planning scheme can be represented by multiple independent building models, or by an area that forms a whole building complex. In the above manner, it is determined which form of the multiple independent simplified models and the composite model is closer to the actual design planning scheme.

[0103] In other implementations, it is also possible to choose to perform in the form of giving priority to matching composite models. That is, it is first determined whether there is a composite model whose matching degree meets the requirements. If so, the corresponding composite model is adopted. If not, matching is performed in a single model. This method can reduce the number of simplified models matched as much as possible, greatly improving efficiency. In other implementations, a single model can also be matched first.

[0104] In some implementation processes, even if a corresponding simplified model is matched, the gap between the simplified model and the actual design in the planning and design scheme may be large. Figure 6 As shown, in some embodiments, after matching the simplified model with the highest fitness from the single model and the composite model, the method further includes:

[0105] S301, determining whether the matching degree of the simplified model with the highest matching degree reaches a set threshold, if not, executing step S302;

[0106] S302, forming a new composite model based on the combination of the single models and saving it;

[0107] According to the design in the planning and design scheme, the single model can be automatically combined to form a new composite model. This greatly improves the matching success rate of the simplified model and makes it more flexible and able to adapt to various design requirements.

[0108] Among them, Figure 7 As shown, forming a new composite model based on the combination of single models may include:

[0109] S3021. Split the requirements of the corresponding planning and design area;

[0110] S3022, extracting a plurality of single models corresponding to different requirements respectively;

[0111] S3023, placing each single model corresponding to different requirements into a temporary model space;

[0112] S3024, scaling the temporary model space as a whole to match the planned design area;

[0113] S3025, saving the temporary model space as a new composite model;

[0114] The temporary model space can be formed into a simplified space of corresponding shape according to the design in the design plan, for example, a regular graphic space with space dimensions that meet the requirements. The temporary model space can be understood as a temporary container, in which multiple single models are placed so that they have the corresponding attributes of these single models. The attributes of the single models corresponding to different requirements can be combined to form a composite model that is more compatible with the design in the design plan.

[0115] In this embodiment, the design deduction based on the planning plan includes at least one of the following:

[0116] Road and traffic status simulation, such as simulation of the overall road layout and traffic status to determine whether there will be obvious conflicts, and simulation of the direction of vehicle and pedestrian flow.

[0117] Compliance determination, such as whether the scope of planning and design exceeds the red line, whether there are obvious problems with the volume ratio, building coverage ratio, green coverage ratio, and building height. In actual applications, these parameters can be entered into the system according to the regulations of relevant departments, and the system will automatically determine based on the entered parameters.

[0118] In addition to the above deduction, other verifications can also be performed, which are not limited by this embodiment. It can be seen that the deduction content in actual applications does not need to rely entirely on the final accurate model. This embodiment can quickly verify and judge a part of the deduction verification content by matching the simplified model for pre-verification, thereby improving production efficiency and saving resources.

[0119] This embodiment also provides a three-dimensional digital planning and design system 100, such as Figure 8 As shown, it includes:

[0120] A matching module 101 is used to obtain an input planning and design scheme and match a simplified model for the planning and design scheme;

[0121] A plan generation module 102 is used to generate a planning plan by integrating a simplified model into the three-dimensional real scene model;

[0122] A deduction module 103 is used to perform design deduction based on the planning plan;

[0123] The result comparison module 104 is used to compare the design deduction result with the planning target, and integrate the design modeling data in the planning design scheme into the three-dimensional real scene model after the comparison result meets the expectation.

[0124] The specific steps that can be executed by the modules in the three-dimensional digital planning and design system 100 of this embodiment can also refer to the description of the three-dimensional digital planning and design method provided above in this embodiment, which will not be described in detail in this embodiment.
