With the development of location service technology and the increase of users' demand for positioning and navigation, the development of map technology has been gradually promoted: from two-dimensional to three-dimensional, from outdoor to indoor, from desktop to mobile, map technology has undergone revolutions.
As we all know, due to the low efficiency and high cost of traditional modeling methods, 3D has not been deployed on a large scale in the field of smart cities and Internet maps. The 2.5D maps that were launched in the past two years were gradually abandoned by the market due to factors such as slow update speed and high cost. Since the advent of real-world 3D modeling technology, it has gradually been used in the field of smart cities due to its full-element, fully automatic and other features. At present, through the 3D-Exhibition engine developed by Zhongwei Space, the data can be generated into a three-dimensional visualization management platform.
One of the most important functions of the city's 3D model is the visual expression of the operation status of the elements in the city space. It is represented by 3D city scenes and building information models. 3D city models are commonly used in engineering fields such as urban macro planning and micro design. With 5G With technological development, all walks of life are beginning to apply 3D visualization technology, and three-dimensional expressiveness has become a must for spatial data analysis!
Education: Visualize educational data and flourish!
Tourism: Tourism data visualization, national attention!
Park: The visualization of park data, the sweet pastry of local industry development!
Traffic: Traffic data is visualized, police uncles can also handle cases remotely!
Medical: Medical data visualization, a life-saving route that everyone pays attention to!
Based on the division of urban areas, the Zhongwei Space Development Group has built visual templates based on the basic data of urban operations for different industries, and three-dimensionally displayed regional analysis maps with education, tourism, and parks as the data plane.
From the perspective of data visualization, after the 3D city modeling is completed, real-time sensor data sources are connected to realize the dynamic display of the large screen of the command center for daily operations.
From the perspective of city operators, visualization is just a way of technical realization.
The premise needs to integrate a large number of urban elements to run real-time data, such as traffic, buildings and other information, to reproduce the three-dimensional landscape of the city through real-time interaction, which is equivalent to a real-life simulation process, and then integrates the business data of various departments of the city, based on visualization. Then carry out various analyses.
The ultimate goal of the 3D map is to locate accurately. For example, search for KFC. The 3D map can tell us exactly which building we are on, or even which floor of the building.
We can combine such requirements to seamlessly integrate the indoor and outdoor fine models constructed by real-world 3D models, BIM models, artificial models, and point clouds, and quickly and automatically restore a real world from macro to micro, from outdoor to indoor.
