Problems solved by technology

[0004] At present, domestic and foreign studies on urban 3D building high-precision spatial large databases mainly focus on the collection, analysis, and visualization of single data, less attention is paid to the mutual influence relationship between various data systems in urban space, and there is even a lack of comprehensive urban space at the level of 3D buildings. Production and dynamic display technology of overlaid three-dimensional building high-precision spatial large database
In the acquisition of high-precision spatial large databases of urban 3D buildings, there is a lack of urban geographic spatial coordinates, data processing in a single dimension, and lagging behind in the field of urban spatial big data acquisition, integration and display of large-scale composite data

Abstract

The present invention disclosed the comprehensive collection and analysis method of high -precision space big data in the city's three -dimensional building.4 Land database; (4) build high -end databases such as high -end ‑; (5) Establish a three -dimensional model of the city to form a high -precision space big data of the three -dimensional building of the city;The present invention can deal with the processing of massive space form data, carry out a fast and efficient urban three -dimensional building high -precision space big data acquisition and the measurement of spatial structure elements, and realize the comprehensive collection and information synthesis of basic data based on urban spatial analysis based on artificial intelligence systems.It helps the comprehensive, standardized and efficient operation of urban planning and design.

Description

technical field [0001] The invention relates to a mining, collection and analysis of urban spatial big data, in particular to a comprehensive collection and analysis method of urban three-dimensional building high-precision spatial big data. Background technique [0002] Urban high-precision spatial big data with three-dimensional buildings as the smallest unit has always been the core foundation of spatial planning and even urban planning, but this database has the characteristics of difficulty in obtaining, long cycle, and small samples. In response to this problem, it is of great significance to obtain a large database of urban space by using a multi-source approach of high-tech informatization and intelligentization for the study of the evolution of urban spatial form and the internal development mechanism of the city. Compared with the role of traditional remote sensing satellite maps in distinguishing various elements of the city through infrared bands, the high-precis...
