[0047] Multiple embodiments will be provided below to specifically introduce the data visualization processing method, apparatus, and electronic device.

[0048] Embodiment 1:

[0049] To solve the problem that Cesium in the prior art cannot support the I3S three-dimensional data service of the OGC standard, resulting in the inability to display data in the Cesium framework, an embodiment of the present invention provides a data visualization processing method, which is applied to the visualization processing of the I3S data service in the Cesium framework. See Figure 1 As shown, the method includes:

[0050] Step S102, monitor the visualization range of the map scene, and obtain the service information corresponding to the I3S data service within the visualization range.

[0051] In one implementation, the visualization range of the map can be monitored first, and it is determined whether the waiting time within the visualization range exceeds the waiting time threshold. If the waiting time exceeds the preset waiting time threshold, a request for obtaining data within the visualization range is initiated according to the I3S data service address, and the service information of the visualization range returned after obtaining the response to the acquisition request is obtained. The service information is information related to the service, and may include at least one of the following information: service meta-information, data access path, coordinate system, and coordinate value.

[0052] The above I3S data service is an OGC standard service, and the service address is a url path. The initiated acquisition request can be an HTTP request.

[0053] In one example, when it is determined that the service is an accessible service, then according to the above service information, the service root node information is requested, and after obtaining a node data, the state of the display of the node and its child node data on the map scene is judged based on the visualization range. According to different agreed states, it can be marked as three types: removal, drawing, and displaying child nodes. If it is the removal type, the model is found and removed on the map; if it is drawing, the data is parsed; if it is displaying child nodes, after obtaining the child node content according to the data child node information, the child node is used as a node data, and then judged, and a recursive request is made until all the corresponding operations on the node data and its child node data are completed and then stopped.

[0054] Step S104: Parse the service information to determine the parsed feature information, where the parsed feature information includes at least geometric body information and texture information.

[0055] In an optional implementation, a request can be initiated based on the request path of the service information to obtain geometric coordinate points and texture information, where the geometric coordinate points are represented by a byte array. Then, the byte array is parsed based on the geometric type to determine the target coordinate values corresponding to the geometric coordinate points, where the geometric type includes points, lines, or planes.

[0056] The above request path may include a first request path for the geometric body and a second request path for the texture. For ease of understanding, the flowchart for obtaining the geometric body information and texture information through the two request paths can be seen Figure 2 as shown. Requests are initiated separately through the first request path for the geometric body and the second request path for the texture to obtain the corresponding geometric body information and texture information, and then they are loaded.

[0057] The above target coordinate values may include position coordinates, texture coordinates, and normal coordinates. When parsing the byte array based on the geometric type to determine the target coordinate values corresponding to the geometric coordinate points, the geometric coordinate points can first be divided based on the geometric type (such as points, lines, planes), and then the divided geometric coordinate points are intercepted and calculated to determine the position coordinates, texture coordinates, and normal coordinates.

[0058] When the obtained coordinates are position coordinates, the position coordinate values corresponding to the position coordinates can be further obtained, and the position coordinate values are converted into Cartesian coordinate values corresponding to the Cesium framework.

[0059] Step S106: Perform conversion processing on the geometric body information, and obtain the target object under the Cesium framework based on the converted geometric body information and texture information, so as to perform visual display by loading the target object.

[0060] After determining the Cartesian coordinates, texture coordinates, and normal coordinates as above, an initial object of the Cesium framework can be constructed based on the three types of data corresponding to the Cartesian coordinates, texture coordinates, and normal coordinates, where the initial object includes a Geometry object; then, the Geometry object is rendered based on the texture information to obtain the target object of the Cesium framework; where the target object includes a Primitive object.

[0061] In an optional embodiment, after obtaining the corresponding coordinates and texture information of the data through parsing, it can be converted into the corresponding primitive type through the API of Cesium for display in the map scene. In specific implementation, the Cartesian coordinates, texture coordinates, and normal coordinates obtained by converting the position coordinates can be used to construct a Geometry object of the Cesium framework first, and then the Geometry object and texture information can be used to construct a Primitive object of the Cesium framework. Finally, the Primitive object is added to the scene through the API of the Cesium framework for rendering to obtain the target object.

[0062] Furthermore, before determining the service information of the visualization range in this embodiment, it is also possible to first determine whether the visualization range of the map scene has changed. If the visualization range has changed, update the visualization range based on the changed data, load and display the newly added data in the updated visualization range, and remove the data that is not in the visualization range after the update.

[0063] After the visible range of the map scene has changed, it is necessary to load and display the data according to the data in the visible range and update it. In specific implementation, the API of Cesium can be used to bind the event of map visualization change. When the visualization range of the map scene has not changed for three seconds, it is necessary to process the data in the current visualization range. There are two processing methods: loading and updating. See Figure 3 as shown. Both methods perform the above three steps of request, parsing, and loading. In the link of requesting data, it has been determined the data that needs to be displayed in the current scene, and the data that does not need to be displayed will be removed to achieve the purpose of data update.

[0064] In summary, this solution mainly includes the following four steps:

[0065] The first step is to request the data within the current visualization range and determine the data that needs to be loaded, removed, or updated in the current range.

[0066] The second step is to parse the information such as geometries, normals, and textures in the requested data. The third step is to construct a native object of the Cesium framework based on the information obtained through parsing and load it through the API.

[0067] The fourth step is to bind the corresponding events so that the data in the visualization range can be updated as the map scene is browsed.

[0068] This method realizes the visualization extension of I3S data service supported by the Cesium framework by performing coordinate conversion at appropriate positions, enabling the project to load the I3S data service. It solves the problem that when using Cesium as the development framework for a Web GIS project and needing to display I3S 3D data service while retaining the functional characteristics of Cesium without having to switch the development framework again. This reduces the learning cost of developers and the project development cost. In addition to supporting geographic coordinate system data, it also supports projected coordinate system data. By means of the mutual conversion method between the Cartesian coordinates and WGS84 coordinates in Cesium, and then implementing the conversion method between WGS84 coordinates and projected coordinates, the I3S data service in the projected coordinate system can also be used in the Cesium framework that only supports the WGS84 coordinate system. By leveraging the native Geometry object and Primitive object provided by Cesium, constructing the two types of objects through the I3S node data and loading them through the API of the Cesium framework, the node data in the I3S data service in the map scene is rendered. And this solution does not require any modification to the Cesium framework. Developers can expand it by encapsulating it into an independent component by themselves, which does not affect the original functions and also greatly reduces the development complexity.
