[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0025] Currently, there are slow and lagging phenomena in the loading and display of mine three-dimensional scenes. Based on this, the embodiments of the present invention provide a method, device, server, and storage medium for loading a mine three-dimensional model, which can accelerate the display of the mine three-dimensional scene and significantly improve the rendering efficiency of the mine three-dimensional scene.

[0026] To facilitate the understanding of this embodiment, first, a method for loading a mine three-dimensional model disclosed in the embodiments of the present invention will be introduced in detail. Refer to Figure 1 The flowchart of a method for loading a mine three-dimensional model shown, and this method mainly includes the following steps S102 to step S106:

[0027] Step S102, if a model loading instruction is received, it is determined whether target model cache data corresponding to the model loading instruction is stored in the database set. The database set includes a database and a cache. Model cache data is stored in the database set, and the model cache data is generated based on a pre-established first mine three-dimensional model. The first mine three-dimensional model can be obtained by parsing data such as coordinates and model parameters in the unified geographic (projection) coordinate system of the GIS platform through an SDK (Software Development Kit). The model parameters include cross-sectional shape, horizontal azimuth angle, inclination angle, length, etc. In one implementation, the target model cache data corresponding to the model loading instruction can be first searched in the cache. If the target model cache data is not found in the cache or the target model cache data has expired, the target model cache data corresponding to the model loading instruction is searched in the database. If the target model cache data is found in the database, the target model cache data is synchronized to the cache and the target model cache data is returned. If the target model cache data is never found in the database, the first mine three-dimensional model is reconstructed, and the required target model cache data is obtained based on the first mine three-dimensional model.

[0028] Step S104, if so, read the target model cache data from the database set.

[0029] Step S106, perform parsing processing on the target model cache data to obtain a second mine three-dimensional model corresponding to the target model cache data, and load the second mine three-dimensional model into a specified three-dimensional scene. The second mine three-dimensional model may be a complete first mine three-dimensional model or a partial mine three-dimensional model corresponding to the target business type carried by the model loading instruction. In one implementation manner, the target model cache data can be converted from a binary format to a JSON format, and based on the JSON-format target model cache data and the association relationship (which can also be called an index), a second mine three-dimensional model corresponding to the target model cache data is generated.

[0030] The method for loading a mine three-dimensional model provided by the embodiment of the present invention can obtain the corresponding second mine three-dimensional model by performing parsing processing on the target model cache data, without parsing real coordinates, model parameters, etc. to rebuild the mine three-dimensional model, thereby accelerating the display of the mine three-dimensional scene and significantly improving the rendering efficiency of the mine three-dimensional scene.

[0031] In the case where the target model cache data corresponding to the model loading instruction is not stored in the database set, it is necessary to generate cache data and store the generated cache data in the database set. Specifically, the embodiment of the present invention provides an implementation manner for generating cache data, as shown in the following steps 1 to 4:

[0032] Step 1, obtain the model basic data corresponding to the target model cache data, and build a first mine three-dimensional model based on the model basic data; the model basic data includes coordinate data and / or model parameter data, the first mine three-dimensional model is in JSON format, the coordinate data is the coordinate in the unified geographic coordinate system of the GIS platform, and the model parameter data includes cross-sectional shape, horizontal azimuth, inclination angle, length, etc. In one implementation manner, the coordinate data and the model parameter data can be parsed through the SDK, so as to realize dynamically building the first mine three-dimensional model using the SDK.

[0033] Step 2, establish an association relationship between the first mine three-dimensional model and the model structure data set. The model structure data set is used to represent the geometric structure and / or model material of the first mine three-dimensional model, the model material includes texture and / or texture map, and the association relationship can also be called an index. In specific implementation, standard JSON-format data (that is, the first mine three-dimensional model) is output through the SDK, and the first mine three-dimensional model and the model structure data set are associated through an index.

[0034] Step 3: Divide the model structure dataset into multiple first sub-datasets based on the preset business types, and perform format conversion on each first sub-dataset to obtain the model cache data corresponding to the first three-dimensional mine model. The model cache data is in binary format, and the preset business types include one or more of the following data: underground roadways, working faces, mine field boundaries, water accumulation areas, three zones, boreholes, faults, collapse columns, aquifers, geology, etc., as well as surface buildings above ground. Exemplarily, taking the business type as the working face, there are multiple working faces; a single model refers to one of the working faces, and the structure of a working face includes a geometric structure and materials. In specific implementation, the model structure dataset can be divided into multiple first sub-datasets with the working face as the unit, and then each first sub-dataset is converted into binary data respectively, so as to facilitate subsequent searching and updating with the working face as the unit.

[0035] Step 4: Store the model cache data corresponding to the first three-dimensional mine model in the database set. In one implementation, the model cache data corresponding to the first three-dimensional mine model can be stored in the database, and at the same time, the model cache data is synchronized to the cache.

[0036] In addition, for the foregoing step S102, the embodiment of the present invention also provides an implementation for determining whether the target model cache data corresponding to the model loading instruction is stored in the database set. Refer to Figure 2 the flowchart of another method for loading a three-dimensional mine model shown in the figure. This method mainly includes the following steps a to e:

[0037] Step a: Determine whether the target model cache data corresponding to the model loading instruction is stored in the cache. If so, execute step d; if not, execute step b. In specific implementation, the model loading instruction carries the target business type TYPE and a single model ID (Identity document). Query whether the target model cache data is stored in the cache. The single model ID is also the model identifier.

[0038] Step b: According to the target business type and model identifier carried by the model loading instruction, determine whether the target model cache data is stored in the database. If so, execute step c; if not, end. In practical applications, if the target model cache data is not stored in the cache, then further query whether the target model cache data is stored in the database according to the target business type TYPE and the single model ID.

[0039] Step c: Synchronize the target model cache data to the cache to read the target model cache data from the cache.

[0040] Step d: Determine whether the expiration period of the target model cache data is greater than 0. If so, determine that the target model cache data has not expired and execute Step e; if not, determine that the target model cache data has expired and execute Step b. The expiration period is randomly generated when the target model cache data is stored in the cache. The expiration period is a multiple of a specified threshold and decreases over time. In one implementation, when the target model cache data is stored in the cache, the expiration period is randomly generated in units of 30 days. Additionally, the EXPIRE attribute of the target model cache data is used to represent the expiration period of the data, so as to determine whether the target model cache data has expired based on the EXPIRE attribute.

[0041] Step e: Determine that the target model cache data is stored in the database set.

[0042] After obtaining the target model cache data, the target model cache data can be parsed to obtain the second mine three-dimensional model corresponding to the target model cache data. Specifically, the target model cache data can be converted from the binary format to the JSON format, and based on the JSON-format target model cache data and the association relationship, the second mine three-dimensional model corresponding to the target model cache data can be generated. In practical applications, the binary data obtained from the cache is parsed into JSON data, the data in the standard JSON format is constructed through model indexing and returned, and finally the standard JSON-format data is parsed into a three-dimensional model through the SDK and loaded in the three-dimensional scene.

[0043] To accelerate the display of the three-dimensional scene and improve the rendering efficiency, the three-dimensional model data is simplified, and the three-dimensional model is converted into the standard JSON-format data according to certain rules, and the internal geometric structure, materials (textures, maps) of the model and the relationships between the models are established through indexing. However, as the three-dimensional model grows, its data continuously increases. Facing such a large amount of data, it is unrealistic to cache all of it in the client memory. Therefore, high requirements are imposed on both computer hardware and application software for the efficient visualization of large-scale scenes. The main idea of the embodiments of the present invention is: when loading the mine three-dimensional model in the three-dimensional scene, by reading the three-dimensional model data cached on the server side, the parsing of the GIS basic data coordinates (x, y, z) and model parameters (section shape, horizontal azimuth, inclination angle, length) is omitted, and the process of dynamically creating the model through the SDK is omitted, so as to accelerate the display of the three-dimensional scene and improve the rendering efficiency.

[0044] For ease of understanding, the embodiments of the present invention provide an application example of a method for loading a mine three-dimensional model. Refer to Figure 3The implementation process of a method for loading a three-dimensional mine model is as follows: Specifically, (1) First, initialize the three-dimensional scene, which is used to load the three-dimensional mine model; (2) Determine whether there is target model cache data in the database set; (3) If there is no target model cache data in the database set, dynamically construct the three-dimensional mine model through the SDK; (4) Output the three-dimensional mine model as data in the standard JSON format through the SDK, and associate the model structure through indexing; (5) If there is target model cache data in the database set, first determine whether there is target model cache data in the cache or whether the target model cache data has expired; (6) If the target model cache data does not exist in the cache or has expired, read the target model cache data from the database, and at the same time synchronize the target model cache data to the cache; (7) If there is target model cache data in the cache, read the target model cache data therein; (8) Parse the binary data obtained from the cache into JSON data, construct data in the standard JSON format through model indexing and return; (9) Finally, parse the data in the standard JSON format into a three-dimensional model through the SDK and load it in the three-dimensional scene.

[0045] In the embodiment of the present invention, the three-dimensional model is converted into JSON data, and through indexing association, cache data is constructed and stored on the server side to achieve the effect of sharing among multiple clients. Compared with not using the cache technology, while ensuring the timeliness of dynamic modeling, the display of the three-dimensional scene is accelerated and the rendering efficiency is improved.

[0046] In one implementation, the embodiment of the present invention can also monitor the model basic data to update the model cache data in a timely manner when it is monitored that the model basic data has changed. See Figure 4 The flow schematic diagram of another device for loading a three-dimensional mine model shown, this method mainly includes the following (1) to (4):

[0047] (1) If it is monitored that the model basic data corresponding to the target model cache data has changed, create a third three-dimensional mine model based on the changed model basic data. In practical applications, it can be determined whether the basic data managed by the GIS platform has changed, and if there is no change, exit.

[0048] (2) Establish an association relationship between the third three-dimensional mine model and the model structure data set. In one implementation, if the coordinates, model parameters, etc. of a certain business type (for example: working face) change, then by parsing the data under the unified geographic (projection) coordinate system of the GIS platform, use the SDK to dynamically construct a three-dimensional model.

[0049] (3) Divide the model structure data set into multiple second sub-data sets based on a preset service type, and perform format conversion on each second sub-data set to obtain the changed model cache data. In one implementation, 3. Output the 3D model as standard JSON format data through the SDK. The model structure includes geometric structure, materials (textures, maps). Associate the model structure through indexing, then convert the model structure into binary data module by module, and update the corresponding data in the database according to the service type (e.g., working face) TYPE and the single model ID. At the same time, update the data in the cache database.

[0050] (4) Store the changed model cache data in the database set.
