AI Technical Summary

Technical Problem

Existing technologies are insufficient to accurately describe and quantify the three-dimensional urban form, making it impossible to effectively assess and optimize the three-dimensional urban form during the urban design process.

Method used

This paper presents a method for measuring the morphological characteristics of high-density three-dimensional composite cities. By defining the three-dimensional identification boundary, obtaining the original map data, filtering and processing it, extracting the three-dimensional modeling information, calculating the three-dimensional feature measurement indicators such as three-dimensional base surface coverage, floor area ratio, hierarchical degree, connectivity and overlap, and using a hierarchical clustering algorithm for classification, a three-dimensional city database is constructed for comparison and evaluation.

Benefits of technology

It enables precise description and quantitative analysis of three-dimensional urban forms, effectively evaluates optimized schemes for three-dimensional urban design, supports horizontal and vertical comparisons, and improves the scientificity and accuracy of urban design.

Abstract

The present invention relates to a measurement method for high-density three-dimensional composite urban form characteristics, and a computing apparatus and a storage medium. The measurement method comprises: delineating a three-dimensional identification boundary, and acquiring raw map data; performing screening processing on the raw map data, and performing three-dimensional modeling within the identification boundary; calculating three-dimensional characteristic measurement indices; selecting three-dimensional base coverage rate and three-dimensional base plot ratio to construct a coordinate system, and classifying sample indices into hierarchies according to distribution characteristics; using a hierarchical clustering algorithm to constantly perform iteration until all data is combined into one category; and storing the data, building a three-dimensional urban database, and keeping the data updated. The present invention is aimed at the form characteristics of three-dimensional composite urban development during the renewal of high-density cities, and solves the problems in the prior art of it not being possible to precisely express three-dimensional urban forms and it also not being possible to perform effective quantitative analysis on the three-dimensional urban forms during urban design.
