The Impact Mechanism of Urban Built Environment on Urban Greenways Based on Computer Vision

With the development and widespread adoption of smart machines, researchers across various disciplines and fields are exploring the contributions of computers and intelligent machines to human science and society through interdisciplinary collaboration. In this study, we investigated the potential applications of artificial intelligence and multi-source big data in the selection and design of urban greenways, using the city of Nanjing as a case study. Utilizing computer vision technology and the DeepLabV3+ neural network model, we analyzed over 320,000 street view images and 530,000 fine-grained urban data points from Nanjing. We also trained the place space material quantification model using the Street Space Greening Structure (S.S.G.S) dataset. This dataset not only achieved high-precision semantic segmentation but also surpassed previous datasets in predicting greenery at the street level. The performance metrics for this model are as follows: MIoU is 0.6344, Recall is 0.7287, and Precision is 0.8074. Through Robust regression, we identified several micro and macro-level factors influencing the Panoramic View Green View Index (PVGVI). The results indicate that multiple factors have significant positive or negative effects on PVGVI. This research not only provides new decision-making tools for landscape architecture and urban planning but also opens new avenues for applying artificial intelligence in urban environmental studies.
