Description

Multi-source data scene arrangement and visualization method based on configurable template Technical Field The invention belongs to the technical field of data management and visualization, and particularly relates to a multi-source data scene arrangement and visualization method based on a configurable template. Background Along with the deep advancement of informatization construction, a large amount of heterogeneous multi-source data are stored in the application, including process record data, sensor data, image data, document data and the like. The data has the characteristics of various types, complex time-space association, rich semantic hierarchy and the like, and how to effectively organize, dynamically arrange and scene display the data, so that the scene application of the multi-source data is realized, and the data management and application display are important requirements. Currently, application display of multi-source data mainly has the following problems: First, scene construction is inefficient. The traditional scene construction mode needs to design a scene structure, configure data elements and schedule time sequences from scratch for each specific business scene, and is large in workload and high in repeatability. The lack of a reusable scene template mechanism can not quickly respond to scene construction requirements of different types of service requirements, and severely restricts the application efficiency of multi-source data. Second, the data arrangement is not flexible enough. The existing system mostly adopts a static configuration or script programming mode to organize data elements, and lacks visual editing means. The user is difficult to flexibly adjust and preview the scene elements in real time, and interaction modes such as drag editing, time axis management and the like are not supported, so that the scene arrangement process is complex and difficult to modify. Third, dynamic performance is inadequate. The traditional method is used for data visualization in the form of static charts or simple animations, lacks a unified scheduling mechanism for multiple types of data elements, and is difficult to realize collaborative presentation of different data types (such as pictures, videos, audios, vector data, three-dimensional models and the like). Meanwhile, a flexible visual angle control means is lacking, and the requirement of a user for viewing scenes from different observation scales cannot be met. Fourth, there is a lack of differentiated handling policies for different data types. The existing method adopts unified data loading and rendering modes, and cannot fully consider differences of different data types such as pictures, videos, vector data, raster images, three-dimensional models and the like in terms of loading mechanisms, rendering modes, interaction modes and the like, so that the performance of the system is limited, and the performance of the system is poor. Therefore, it is needed to provide a multi-source data scene arrangement and visualization method based on a configurable template, which realizes rapid organization, flexible arrangement and dynamic performance of multi-source data by establishing a standardized scene template mechanism, a multi-track time axis arrangement mechanism, a granularity resource scheduling algorithm and a multi-view observation scale scheduling strategy, and provides an efficient technical means for business process duplication, performance evaluation and auxiliary decision. Disclosure of Invention The invention provides a multi-source data scene arrangement and visualization method based on a configurable template, which is used for solving the technical problems of low scene construction efficiency, insufficient data arrangement mode, insufficient dynamic performance, lack of differentiated processing strategies aiming at different data types and the like in scene application, realizing standardization organization, efficient arrangement and dynamic visualization of multi-source data, and providing technical support for business process duplication, efficiency evaluation and auxiliary decision. The first aspect of the invention provides a multi-source data scene arrangement and visualization method based on a configurable template, which comprises the following steps: step S1, determining a scene template corresponding to a service based on scene requirements of the service; The scene is a plurality of visual arrangement units combined under a unified space-time frame, wherein the visual arrangement units fuse time-varying geographic elements and scene elements; The scene template comprises a template identifier, a plurality of tracks with time attributes, a track configuration mode, a canvas configuration mode, scene element layout rules, a time axis configuration mode and a view angle configuration mode, wherein the tracks are used for arranging a visual arrangement unit; Step S2, determining the types of data elements
