Urban multi-source data-based street space quality measurement evaluation method and system

Abstract

The invention relates to the field of urban planning, and provides an urban multi-source data-based street space quality measurement evaluation method, which comprises the following steps of: obtaining urban road network data and interest point data in a research area, and preprocessing the urban road network data and the interest point data to obtain street view sampling points; obtaining a plurality of groups of streetscape image data through streetscape sampling points; inputting each piece of streetscape image data into the trained semantic feature extraction model to obtain a streetscapesemantic element data table; constructing a measure evaluation index of the urban street space quality through a street view semantic element data table, the interest point data and the urban road network data; and obtaining the distribution rule and the distribution mode of the urban space quality through the measure evaluation index of the urban street space quality. According to the invention,the street quality is researched on the microcosmic scale, the research range is widened, research is carried out on the perspective of the urban macroscopic level, and the accuracy of street space quality measurement can be remarkably improved.

Description

technical field [0001] The invention relates to the field of urban planning, in particular to a method and system for measuring and evaluating street space quality based on urban multi-source data. Background technique [0002] In recent years, my country's urban construction is changing from incremental expansion to stock upgrading and optimization, and the quality of space is becoming an important part of planning and management. Therefore, in future urban construction, we will not only pay attention to incremental development, but also rationally plan and use stock resources. Philosophy is also very important. The focus of urban planning and construction has shifted from "growth priority" to "quality improvement", and gradually shifted from focusing on the speed of urban construction to focusing on the quality of urban development. With the popularization of information and communication technology and the emergence of geographic big data, many experts and scholars have g...
