Abstract

The invention discloses a comprehensive collection and analysis method for city three-dimensional building high-precision space big data. The method comprises the following steps of (1) establishing abasic geographic and geomorphic database; (2) establishing a city traffic database; (3) establishing a city building-land database; (4) establishing an elevation-contour line database; (5) building acity three-dimensional model, and forming the city three-dimensional building high-precision space big data; and (6) performing data mining and visual display on three-dimensional modeling data. According to the method, the processing of massive space shape data can be coped with; quick and efficient acquisition of the city three-dimensional building high-precision space big data and measurementof space structure elements are carried out; artificial intelligence system-based city space analysis basis data comprehensive collection and information synthesis are realized; and comprehensive, standard and efficient operation of city planning and design is facilitated.

Description

Technical field [0001] The invention relates to an urban space big data mining, collection and analysis, in particular to a comprehensive collection and analysis method of urban three-dimensional building high-precision space 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 difficult access, long period, and small samples. In response to this problem, the use of high-tech informatization and intelligence to obtain a large urban spatial database is of great significance for studying the evolution of urban spatial morphology and the internal development mechanism of the city. Compared with the role of traditional remote sensing satellite maps to distinguish various elements of the city through infrared bands, the large high-precision spatial database of urban three-dimensional...
