基于图像识别的长沙历史步道街景色彩研究

Research on the Street Color of Changsha Historical Trail based on Image Recognition

文章旨在基于图像识别技术与街景图像大数据,对长沙历史步道范围内街景色彩进行定量分析与数字化研判。以长沙历史步道的街景数据为依托,通过建筑图像的语义分割、图像色彩特征的提取与统计分析,揭示出长沙历史步道街景的色彩规律和特点,系统地评价了长沙历史步道街景色彩的空间分布现状,并从建筑界面、标志导视、过渡空间三个微观角度,提出长沙历史步道色彩管控和优化的指导建议,为深入探究长沙历史色彩肌理的延续和城市色彩良性发展提供有益的参考。

This paper aims to explore the quantitative analysis and digital evaluation of street scenery colors within the historical trail range of Changsha based on image recognition technology and big data of street scenery images.Based on the street view data of Changsha historical trail,through semantic segmentation of architectural images,extraction and statistical analysis of image color features,the color patterns and characteristics of Changsha historical trail street view were revealed.The spatial distribution of Changsha historical trail street view color was systematically evaluated,and guidance suggestions for color control and optimization of Changsha historical trail were proposed from three micro perspectives:architectural interface,signage guidance,and transition space.This provides useful reference and reference for in-depth exploration of the continuity of historical color texture and the healthy development of urban color in Changsha.
