A method, device and medium for urban multi-dimensional information interaction and scene generation based on CIM

Abstract

The invention provides a method, device and medium for CIM-based urban multi-dimensional information interaction and scene generation. The method includes: constructing a CIM system model based on multi-sensor data, and mining, judging and processing the collected CIM multi-dimensional real data , associate heavy multi-source heterogeneous data into the CIM system model, when the data collected by at least one of the multi-sensors changes, the real-time dynamic scene 3D reconstruction algorithm based on multi-sensor deep fusion automatically adjusts the CIM based on the CIM system model The environment screen of the system; the CIM system receives the viewing request from the client, and the CIM system generates a three-dimensional graphic based on the viewing data model based on the data in the database of the CIM system and sends it to the client. Based on the information data of various industries generated under the background of smart cities, the present invention summarizes, displays and analyzes intricate and various urban data, establishes a visualization platform, and avoids data loss and inaccuracy caused by time-space rupture as much as possible.

Description

technical field [0001] The invention relates to the technical field of big data processing, in particular to a method, device and medium for city multi-dimensional information interaction and scene generation based on CIM. Background technique [0002] With the rapid development of technologies such as the Internet of Things, Internet communication, virtual reality, and big data, people can easily obtain multi-source heterogeneous data to perceive and express objects. Society interacts and blends, enhancing people's perception of the physical environment of the world. Due to the complexity and large scale of data, how to efficiently and accurately analyze its connotation and use data has become an important focus in the information field. [0003] CIM (City Information Modeling) is based on urban information data to establish an organic complex of three-dimensional urban spatial models and urban information. Urban multi-dimensional information refers to the use of three-dim...

Problems solved by technology

[0005] In the existing technology, the traditional big data project has a large amount of information, low information processing efficiency, and the three-dimensional rendering effect is not good, not accurate enough, and the display effect is poor

For example, WEB3D technology can freely view the entire 3D scene, but it is not fine enough in detail display; due to the huge amount of CIM data, when running on the web page, there are certain requirements for network speed and machine configuration, there are data crashes, scene crashes, Problems such as server crashes are not conducive to customers' viewing; the 3D model scene is too high-quality and the model size is too large, resulting in system freeze problems, which cannot adapt to the client's display and affect the user experience.
