Problems solved by technology

However, the computer image analysis technology based on street view images is not only lacking in interactivity, but also the street view images only contain two-dimensional visual images of the current status of urban streets, which cannot achieve full coverage of viewpoints and make optimal responses
There are currently limited methods for establishing street space evaluations from three-dimensional perspectives on urban streets

Abstract

The invention relates to a street environment quality evaluation method based on VR panoramic visual perception. The invention relates to the technical field of urban design planning, and the method comprises the steps: obtaining main elements and level settings which affect a street environment through pre-investigation; through VR panoramic modeling rendering, a city street environment virtual simulation scheme scene is constructed by means of VR panoramic equipment and a related technology platform; designing a questionnaire, processing questionnaire data by adopting statistical software Stata SEV15.1, and establishing a discrete selection model; constructing a utility function through model fitting, studying and judging the weight relationship of each influence factor, and selecting a walking environment scene with the maximum utility for the pedestrian according to the random utility theory of a discrete selection model; sequentially arranging absolute values of the weight relations from large to small to obtain preference analysis of different types of crowds on street environment element selection behaviors; and ArcGIS software is used for analysis to obtain an overall evaluation map of the actual street environment in the city.

Description

technical field [0001] The invention relates to the technical field of urban design and planning, and relates to a street environment quality evaluation method based on VR panoramic visual perception. Background technique [0002] Streets are an important part of urban landscape, and the evaluation of street environmental quality is of great value for urban planning and renewal. The quality of urban street environment refers to people's subjective preference for daily streets, which provides an important basis for people to understand the interaction between urban environment and residents' mental health. Accurate evaluation of street environmental quality can integrate people's preferences for the environment into scientific urban planning and renewal in the process of urban development, which plays an important role in urban planning and design. [0003] Stated Preference Survey (Stated Preference Survey) refers to the willingness survey method to obtain "people's subject...
