At present, the phenomenon of slow and unsmooth loading display of the three-dimensional mine scene exists, and based on the phenomenon, the invention provides a loading method, a loading device, a server and a storage medium of a three-dimensional mine model, so that the display of the three-dimensional mine scene can be accelerated, and the rendering efficiency of the three-dimensional mine scene is obviously improved.
To facilitate understanding of this embodiment, first, a method for loading a three-dimensional mine model disclosed in this embodiment of the present invention is described in detail, referring to a schematic flow chart of a method for loading a three-dimensional mine model shown in fig. 1, where the method mainly includes the following steps S102 to S106:
and step S102, if the model loading instruction is received, judging whether target model cache data corresponding to the model loading instruction is stored in the database set. The database set comprises a database and a cache, model cache data are stored in the database set, the model cache data are generated based on a pre-established first mine three-dimensional model, the first mine three-dimensional model can be obtained by analyzing data such as coordinates and model parameters under a GIS platform unified geographical (projection) coordinate system through an SDK (Software Development Kit), and the model parameters comprise section shapes, horizontal azimuth angles, inclination angles, lengths and the like. In an embodiment, target model cache data corresponding to a model loading instruction may be searched in a cache, if the target model cache data is not found in the cache or the target model cache data is expired, the target model cache data corresponding to the model loading instruction is searched in a database, if the target model cache data is found in the database, the target model cache data is synchronized into the cache and returned to the target model cache data, and if the target model cache data is not found in the database, a first three-dimensional mine model is reconstructed, and the required target model cache data is obtained based on the first three-dimensional mine model.
And step S104, if so, reading the target model cache data from the database set.
And S106, analyzing the target model cache data to obtain a second mine three-dimensional model corresponding to the target model cache data, and loading the second mine three-dimensional model into the specified three-dimensional scene. The second mine three-dimensional model may be a complete first mine three-dimensional model, or may be a local mine three-dimensional model corresponding to a target service type carried by the model loading instruction. In an implementation manner, the target model cache data may be converted from a binary format to a JSON format, and based on the target model cache data in the JSON format and an association relationship (which may also be referred to as an index), a second three-dimensional mine model corresponding to the target model cache data is generated.
According to the loading method of the three-dimensional mine model, provided by the embodiment of the invention, the corresponding second three-dimensional mine model can be obtained by analyzing the target model cache data, and the real coordinates, model parameters and the like do not need to be analyzed to rebuild the three-dimensional mine model, so that the display of the three-dimensional mine scene can be accelerated, and the rendering efficiency of the three-dimensional mine scene is obviously improved.
Specifically, the embodiment of the present invention provides an implementation manner for generating cache data, which refers to the following steps 1 to 4, in which cache data needs to be generated and stored in a database set when target model cache data corresponding to a model load instruction is not stored in the database set:
step 1, obtaining model basic data corresponding to target model cache data, and constructing a first mine three-dimensional model based on the model basic data; the model basic data comprise coordinate data and/or model parameter data, the first mine three-dimensional model is in a JSON format, the coordinate data are coordinates of a GIS platform unified geographic coordinate system, and the model parameter data comprise section shapes, horizontal azimuth angles, inclination angles, lengths and the like. In one embodiment, the coordinate data and the model parameter data may be resolved by the SDK, thereby enabling dynamic construction of the first three-dimensional model of the mine using the SDK.
And 2, establishing an incidence relation between the first mine three-dimensional model and the model structure data set. The model structure data set is used for representing the geometric structure and/or the model material of the first mine three-dimensional model, the model material comprises texture and/or a map, and the incidence relation can also be called as an index. In a specific implementation, data in a standard JSON format (i.e., 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.
And 3, dividing the model structure data set into a plurality of first sub data sets based on the preset service type, and performing format conversion on each first sub data set to obtain model cache data corresponding to the first mine three-dimensional model. The model cache data is in a binary format, and the preset service types comprise one or more of data of underground roadways, working faces, well field boundaries, ponding areas, three areas, drilling holes, faults, collapse columns, aquifers, geology and the like and ground buildings above the well. Illustratively, taking the service type as a working surface as an example, the working surface has a plurality of working surfaces; the single model refers to one of the working surfaces, and the structure of one working surface comprises a geometric structure and a material. In specific implementation, the model structure data set may be divided by taking the working surface as a unit to obtain a plurality of first sub data sets, and each first sub data set is converted into binary data, so as to facilitate subsequent searching and updating by taking the working surface as a unit.
And 4, storing model cache data corresponding to the first mine three-dimensional model into a database set. In one embodiment, the model cache data corresponding to the first mine three-dimensional model may be stored in a database, and the model cache data may be synchronized into a cache.
In addition, as to the step S102, an embodiment of the present invention further provides an implementation manner of determining whether a database set stores target model cache data corresponding to a model loading instruction, referring to a schematic flowchart of another mine three-dimensional model loading method shown in fig. 2, where the method mainly includes the following steps a to e:
step a, judging whether target model cache data corresponding to the model loading instruction is stored in the cache. If yes, executing step d; if not, executing the step b. In a specific implementation, the model loading instruction carries a target service TYPE and an Identity document (Identity document) to query whether target model cache data is stored in the cache, and the Identity document is also a model identifier.
And b, judging whether target model cache data are stored in the database or not according to the target service type and the model identification carried by the model loading instruction. If yes, executing step c; if not, the process is ended. In practical application, if the target model cache data is not stored in the cache, whether the target model cache data is stored in the database is further inquired according to the target service TYPE TYPE and the single model ID.
And c, synchronizing the target model cache data to the cache so as to read the target model cache data from the cache.
And d, judging whether the validity period of the target model cache data is greater than 0. If yes, determining that the cache data of the target model is not expired, and executing the step e; if not, determining that the target model cache data is expired, and executing the step b. The valid period is randomly generated when the target model cache data is stored in the cache, is a multiple of a specified threshold value, and is reduced along with the time. In one embodiment, when the target model cache data is stored in the cache, an expiration date is randomly generated in units of 30 days, and in addition, an EXPIRE attribute of the target model cache data is used for representing the expiration date of the data, so that whether the target model cache data is expired is judged according to the EXPIRE attribute.
And e, determining that the target model cache data is stored in the database set.
After the target model cache data are obtained, the target model cache data can be analyzed to obtain a second mine three-dimensional model corresponding to the target model cache data, specifically, the target model cache data can be converted from a binary format into a JSON format, and the second mine three-dimensional model corresponding to the target model cache data is generated based on the target model cache data and the association relation in the JSON format. In practical application, binary data acquired from the analysis cache is converted into JSON data, data in a standard JSON format is constructed through model indexes and returned, and finally the data in the standard JSON format is analyzed into a three-dimensional model through the SDK and loaded in a three-dimensional scene.
In order to accelerate the display of a three-dimensional scene and improve the rendering efficiency, the data of the three-dimensional model is simplified, the three-dimensional model is converted into data in a standard JSON format according to a certain rule, and the relationship among the internal geometric structure, the material (texture and map) and the model is established through indexes. However, as the three-dimensional model grows, the data of the three-dimensional model continuously increases, and it is impractical to cache all the huge data in the memory of the client in the face of the huge data, so that the efficient visualization of a large range of scenes puts very high requirements on computer hardware and application software. The main idea of the embodiment of the invention is as follows: when the three-dimensional mine model is loaded in the three-dimensional scene, the analysis of coordinates (x, y, z) of GIS basic data and model parameters (section shape, horizontal azimuth angle, inclination angle and length) is omitted by reading the three-dimensional model data cached by the server, and the process of dynamically creating the model by the SDK accelerates the display of the three-dimensional scene and improves the rendering efficiency.
For convenience of understanding, an embodiment of the present invention provides an application example of a loading method for a three-dimensional mine model, and reference is made to an implementation process of the loading method for a three-dimensional mine model shown in fig. 3, specifically: (1) Firstly, initializing a three-dimensional scene, wherein the three-dimensional scene is used for loading a three-dimensional model of a mine; (2) Judging whether target model cache data exist in the database set or not; (3) If the database set does not have target model cache data, dynamically constructing a three-dimensional mine model through the SDK; (4) Outputting the three-dimensional mine model into data in a standard JSON format through an SDK (software development kit), and associating a model structure through indexing; (5) If the database set has target model cache data, firstly judging whether the target model cache data exists in the cache or whether the target model cache data is overdue; (6) If the target model cache data in the cache does not exist or is overdue, reading the target model cache data of the database, and synchronizing the target model cache data into the cache; (7) If the target model cache data exist in the cache, reading the target model cache data; (8) Converting binary data acquired from the analysis cache into JSON data, constructing data in a standard JSON format through model indexes, and returning; (9) And finally, analyzing the standard JSON format data into a three-dimensional model through the SDK and loading the three-dimensional model in a three-dimensional scene.
The embodiment of the invention converts the three-dimensional model into JSON data, constructs cache data through index association and stores the cache data to the server, thereby realizing the sharing effect of multiple clients. Compared with the method without using a cache technology, the method has the advantages that the dynamic modeling timeliness is guaranteed, the display of a three-dimensional scene is accelerated, and the rendering efficiency is improved.
In an implementation manner, the embodiment of the present invention may further perform snooping on the model basic data, so as to update the model cache data in time when it is snooped that the model basic data is changed. Referring to a flow chart of another loading device for a three-dimensional mine model shown in fig. 4, the method mainly includes the following steps:
and (I) if the model basic data change corresponding to the target model cache data is monitored, establishing a third mine three-dimensional model based on the changed model basic data. In practical application, whether basic data managed by the GIS platform changes or not can be judged, and the GIS platform exits if the basic data does not change.
And (II) establishing an incidence relation between the third mine three-dimensional model and the model structure data set. In one embodiment, if the coordinates, model parameters, etc. of a certain service type (e.g., a working surface) change, the three-dimensional model is dynamically built using the SDK by parsing the data in the GIS platform unified geographic (projection) coordinate system.
And thirdly, dividing the model structure data set into a plurality of second sub data sets based on the preset service type, and performing format conversion on each second sub data set to obtain the changed model cache data. In one embodiment, 3, outputting the three-dimensional model as standard JSON format data through SDK, wherein the model structure comprises a geometric structure and a material (texture and a map), associating the model structure through index, then modularly converting the model structure into binary data, updating corresponding data in the database according to the TYPE of the service (such as a working face) and the ID of the single model, and simultaneously updating the data of the cache database.
And (IV) storing the changed model cache data into a database set.
