Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The overhead line model processing method provided by the application can be applied to the application environment shown in fig. 1. Wherein the terminal 102 communicates with the server 104 via a network. The terminal 102 obtains the overhead line information and the corresponding model object from the local storage module or the storage module of the server 104, obtains the three-dimensional point data set of the target device, and processes the three-dimensional point data set to obtain the cache model object information. The terminal 102 may be, but not limited to, various personal computers, notebook computers, smart phones, tablet computers, and portable wearable devices, and the server 104 may be implemented by an independent server or a server cluster formed by a plurality of servers.
In one embodiment, as shown in fig. 2, a method for processing a model of an overhead line is provided, which is described by taking the method as an example applied to the terminal 102 of fig. 1, and includes the following steps:
step S201, obtaining line information of the overhead line and a model object corresponding to the target device in the overhead line.
The line information may be a topology structure of the overhead line, equipment information of the overhead line, and the like. The line information can be in the form of three-dimensional model data, point cloud, three-dimensional pipeline, three-dimensional point and line surface, BIM and other data. When the three-dimensional model of the overhead line is constructed, the terminal 102 may obtain line information of the overhead line. The target equipment in the overhead line can be equipment such as a tower, an insulator string and a lead of the overhead line. The target equipment can be all equipment on the overhead line, and can also determine required part of equipment according to the requirements of the overhead line model construction. The equipment on the overhead line is provided with corresponding model objects, and each model object can be used for constructing a three-dimensional model of the overhead line.
In a specific implementation, the terminal 102 may obtain the line information of the overhead line stored in various data forms from a local storage module or a storage module of the server 104, and use the line information as a basis for constructing the overhead line model. The terminal 102 may also obtain a model object corresponding to the target device from a local storage module or a storage module of the server 104 according to the target device on the overhead line.
Step S202, a three-dimensional point data set of the target equipment is obtained according to the line information and the model object.
The three-dimensional point data set may include three-dimensional coordinate points of the overhead line target device, model object hooking information corresponding to the three-dimensional coordinate points, and matrix transformation information for performing form transformation on the model object. The three-dimensional coordinate points are spatial distribution points of the target device on the overhead line and are used for indicating the physical position of the target device on the overhead line. The model object hooking information may be information of a model object to be hooked corresponding to the three-dimensional coordinate point, including a storage path and a name of the model object. The matrix transformation information may be parameters for performing translation, rotation, and scaling on the model object when the model object is hung on the three-dimensional coordinate point, and is used for determining the posture of the model object when the model object is hung on the three-dimensional coordinate point. The terminal 102 may call each model object by calling the three-dimensional point data set, and render a spatial three-dimensional model corresponding to a target device of the overhead line.
In a specific implementation, the terminal 102 may process information of the target device into a three-dimensional point data set including three-dimensional coordinate points, model object hooking information, and matrix transformation information according to the acquired line information of the overhead line and the acquired model object corresponding to the target device.
And step S203, processing the three-dimensional point data set according to the tree structure, and caching the three-dimensional point data set according to the corresponding hierarchy of the tree structure to obtain a cache model object data set.
The cache model object data set comprises cache model objects corresponding to the model objects, and a plurality of three-dimensional coordinate points hung to the same model object map the same cache model object. The tree structure may recursively divide the geographic space into tree structures of different levels to build the spatial index. The cache can be a slice cache, corresponding model objects are processed, the model objects are simplified, and rendering efficiency is improved. When building and rendering the model of the overhead line, it is usually necessary to call a model object corresponding to a device on the overhead line, and a large number of identical target devices exist on the overhead line, and the model objects corresponding to the target devices are identical, for example, there may be thousands of insulator strings with identical model features on the overhead line, and model objects hooked on three-dimensional coordinate points of the insulator strings are identical, so that there is repeated loading of the model. When the three-dimensional model is presented, the position and the importance degree of the object model in the display environment are different. Therefore, according to the characteristics presented by the overhead line three-dimensional model and the characteristics called by the model object, hierarchical division and caching are performed on the three-dimensional point data set, so as to achieve better performance.
In a specific implementation, the terminal 102 may divide the three-dimensional point data set into corresponding levels according to a preset tree structure. And caching the three-dimensional point data set according to the hierarchy corresponding to the tree structure, simplifying the model object, mapping the same cache model object by a plurality of three-dimensional coordinate points which are hung to the same model object in the three-dimensional coordinate point data set, realizing multiplexing of the cache model object and obtaining the cache model object data set which is arranged according to the hierarchy.
In the overhead line model processing method, the three-dimensional point data set of the target equipment is obtained by obtaining the line information of the overhead line and the model object corresponding to the target equipment, processing the three-dimensional point data set according to a tree structure, caching the three-dimensional point data and the levels corresponding to the tree structure to obtain a cache model object data set, wherein the cache model object data set comprises cache model objects corresponding to all model objects, a plurality of three-dimensional coordinate points which are hung on the same model object map the same cache model object, the method has the advantages that the three-dimensional coordinate points hung to the same model object in the overhead line can multiplex the cache model object, the model utilization efficiency in the overhead line is improved, the three-dimensional point data set of the overhead line is cached according to the levels corresponding to the tree structures, and the efficiency of building the three-dimensional model of the overhead line is further improved.
In one embodiment, the step of determining to acquire the line information of the overhead line and the model object corresponding to the target device in the overhead line in step S201 includes:
acquiring target equipment corresponding to the overhead line according to the line information of the overhead line; and acquiring a model object corresponding to the target equipment from the equipment model library according to the equipment information of the target equipment.
In this embodiment, the line information of the overhead line includes distribution, connection relationship, spatial geographic position, model, number, type, and the like of the corresponding target device on the overhead line. The terminal 102 may determine the corresponding target device according to the acquired line information of the overhead line. In some embodiments, the target device of the overhead line may be all devices on the overhead line, or may be some devices selected according to needs. The device information of the target device may be information that can be associated with the model object to produce a certain association, such as the number of the target device on the overhead line. The device model library may be a set of model objects corresponding to devices on a pre-configured regional overhead line, and when performing a three-dimensional model of an overhead line, the model objects corresponding to the devices may be retrieved from the device model library. The terminal 102 may obtain the corresponding model object from the device model library according to the device information in the target device. For example, the terminal 102 may perform model processing on towers and insulator strings of the overhead line, obtain information of the towers and the insulator strings in the line information of the overhead line, and determine model objects corresponding to the towers and the insulator strings from the equipment model library according to the equipment information of the towers and the insulator strings.
According to the scheme of the embodiment, the terminal 102 acquires the target equipment corresponding to the overhead line by acquiring the line information of the overhead line, and acquires the corresponding model object from the equipment model library according to the equipment information of the target equipment, so that the model of the overhead line is associated with the actual line information, and data extraction is performed from the existing information, thereby improving the efficiency of acquiring the relevant data of the overhead line.
In one embodiment, before determining that the three-dimensional point data set of the target device is obtained according to the route information and the model object in step S202, the method further includes:
and performing light-weight processing on the line information and the model object to delete the noise data in the line information and the model object.
In this embodiment, the line information may include various data such as an oblique photography model, manual modeling data, BIM, point cloud, three-dimensional pipeline, two-dimensional/three-dimensional point/line plane, and the like, and the processing of the model may be affected by problems such as data format, data consistency, and missing. The model object information corresponding to the target device may have problems of data loss, data duplication and the like. After the terminal 102 obtains the line information and the model object, the data may be subjected to a weight reduction process, such as deleting the duplication point object, simplifying the triangulation network, compressing, and the like, to delete the noise data therein, thereby improving the quality of the data acquired by the terminal 102.
According to the scheme of the embodiment, the terminal 102 deletes the noise data in the acquired line information and the model object by performing light-weight processing on the acquired line information and the model object, so that the quality of the acquired data is improved, and the efficiency of model processing of the overhead line is improved.
In one embodiment, the step of obtaining the three-dimensional point data set of the target device according to the route information and the model object, which is determined in step 202, includes:
according to the line information, obtaining a three-dimensional coordinate point of the target equipment on the overhead line; acquiring storage path information of the model object as model object hanging information corresponding to the three-dimensional coordinate point; acquiring matrix transformation information of the model object corresponding to the three-dimensional coordinate point according to the line information and the model object; and obtaining a three-dimensional point data set according to the three-dimensional coordinate points, the model object hanging information and the matrix transformation information.
In this embodiment, the three-dimensional point data set may be a three-dimensional coordinate point of a target device on an overhead line, model object hooking information and matrix transformation information corresponding to the three-dimensional coordinate point, and may be obtained according to line information and a model object corresponding to the target device. Specifically, the terminal 102 may obtain a spatial three-dimensional coordinate point of the target device on the physical space of the overhead line according to the line information of the overhead line, and the three-dimensional coordinate point may be used to indicate a position of the target device on the overhead line model. The model object hooking information may include a storage path of the model object hooked by the three-dimensional point, and the storage path may be an absolute path including a storage path and a storage name of the model object entity. The storage path of the model object may be obtained from the device model library according to the determined association of the target device and the model object. When the three-dimensional model of the overhead line is presented, the presentation posture of the target device on the overhead line can be determined through the matrix transformation information, and the terminal 102 can obtain the matrix transformation information of the model object on the three-dimensional coordinate point according to the line information of the overhead line and the model object corresponding to the target device, and determine the presentation posture of the model object on the three-dimensional coordinate point. For example, the terminal 102 may process the acquired information of the tower and the insulator string to obtain a corresponding three-dimensional point data set. The terminal 102 calls the three-dimensional point data set, and can render a three-dimensional model of a tower and an insulator string on the overhead line.
In the solution of the above embodiment, the terminal 102 obtains the three-dimensional coordinate point of the target device through the line information, obtains the model object hooking information through the storage path information of the model object, obtains the corresponding matrix transformation information through the line information and the model object, and finally obtains the three-dimensional point data set of the target device, and the three-dimensional point data of the plurality of target devices are processed in the same manner, so that the normalization and consistency of the data in the three-dimensional point data set of the target device are improved.
In one embodiment, the step S203 of processing the three-dimensional point data set according to a tree structure, and caching the three-dimensional point data set according to a hierarchy corresponding to the tree structure to obtain a cached model object data set includes:
establishing a hierarchy of the three-dimensional point data corresponding to the tree structure in the three-dimensional point data set according to a preset tree structure; and caching the three-dimensional point data set according to the hierarchy to obtain a cache model object data set.
In this embodiment, the terminal 102 may establish a spatial index of the three-dimensional point data set according to a tree structure. The tree structure may be a spatial quad tree structure and/or a spatial octree structure. The spatial quadtree and the spatial octree structure are different in refinement degree, and can be used for layering and displaying requirements of different precisions respectively, and the spatial quadtree and the spatial octree structure can be simultaneously applied. Taking a spatial quad-tree as an example, a geographic space is recursively divided into tree structures of different levels, a space in a known range is equally divided into four equal subspaces, and the recursion is carried out in this way until the levels of the tree reach a certain depth or meet a certain requirement, and then the division is stopped. And dividing the three-dimensional point data set into corresponding levels according to the spatial index determined by the quadtree. After the corresponding tree structure hierarchy of the three-dimensional point data set is determined, caching is carried out on the three-dimensional point data set according to each hierarchy, so that the structure and the mapping relation of the model object in the three-dimensional point data set are optimized, and the rendering efficiency is improved.
In some embodiments, the terminal 102 may perform instantiation processing on the model object in the three-dimensional point data set, so as to repeatedly render the same model, and obtain a cache model object. Instantiation rendering is suitable for a scenario where the same model is used for rendering multiple times, such as the same tower, insulator string, etc. on an overhead line. For a plurality of three-dimensional coordinate points hung to the same model object, the same cache model can be mapped, the reuse of the cache model object is realized, and the model rendering efficiency of the overhead line is improved.
In the scheme of the embodiment, the terminal 102 establishes the levels corresponding to the three-dimensional points in the three-dimensional point data set through the tree structure, caches the levels, establishes the spatial index distribution of the three-dimensional point data set, and improves the efficiency of overhead line model processing.
In one embodiment, the above method further comprises,
and caching the three-dimensional point data set according to the level of the hierarchy according to a level of detail LOD algorithm to obtain a cache model object data set.
In this embodiment, a level of detail lod (levels of detail) algorithm determines resource allocation for object rendering according to a position and an importance of a node of a three-dimensional object model in a display environment, and reduces the number of faces and the degree of detail of an unimportant object, thereby obtaining a high-efficiency rendering operation. In a three-dimensional scene, the system may simplify or no longer display a particular geometric form based on the reference point of the viewer, e.g., as an object is farther from the reference point, the object may be represented with a coarser level of detail, and conversely, with a finer level of detail, the object may be represented with less detail. The level of detail LOD algorithm can process the model through algorithms such as a culling algorithm, mesh simplification and the like. The level of detail LOD algorithm may be used to process models that are simplified to a different degree depending on the level of detail displayed. In some embodiments, each level of detail level of the LOD may correspond to a respective level in the tree data structure. The terminal 102 may cache the model object corresponding to the three-dimensional coordinate point of each hierarchy according to the hierarchy corresponding to the three-dimensional coordinate point determined by the tree structure according to the level of detail LOD algorithm, so as to obtain a cache model object dataset including data corresponding to the three-dimensional coordinate points of all the target objects. The cache model object data set has clear hierarchical structure, simplified model structure and small data storage amount, and improves rendering efficiency.
According to the scheme of the embodiment, the terminal 102 caches the three-dimensional point data set according to the level of detail LOD algorithm to obtain the cache model object data set with clear hierarchical structure and simplified model, so that the practicability of the model of the overhead line is improved.
In one embodiment, the method comprises:
processing model object hanging information and matrix transformation information corresponding to each three-dimensional coordinate point according to a level corresponding to each three-dimensional coordinate point in a three-dimensional point data set and according to a level of detail level LOD algorithm to obtain cache model object information and cache matrix transformation information corresponding to each three-dimensional coordinate point; and obtaining a cache model object data set according to the cache model object information and the cache matrix transformation information corresponding to each three-dimensional coordinate point.
