长沙市主城区建筑色彩基因提取与分析研究

Extraction and Analysis of Architectural Color Gene in the Main Urban Areas of Changsha City

以《长沙市城市色彩规划》为依据,运用计算机深度学习和街景图像,对长沙市主城区范围内的建筑色彩进行了可视化分析。长沙市主城区城市色彩的色调以黄红为主,色彩的饱和度均为低值,呈现以低饱和度的色彩为主、高饱和度色彩为点缀的特点,色彩的明度整体偏低,说明了城市内色彩偏暗的现状。此外,长沙市内黄红色调主要运用于居住建筑、低层商业及传统型商业街区的建筑外立面中,蓝绿色调主要运用于现代型商业的高层建筑和底层商业建筑的立面中,存在同一空间内涉及多个色系色彩使用的情况,导致空间内出现建筑色彩混乱的现象。基于长沙市城市色彩的现状和特点、,探讨了城市色彩分析的优化方式。

Based on The Urban Color Planning of Changsha,this study makes a visual analysis of the architectural color in the main urban areas of Changsha by using computer in-depth learning and street view images. The tones of the urban color in the main urban areas of Changsha are mainly yellow and red,and the saturation of the color is low,which shows the characteristics of the color with low saturation as the main body and the color with high saturation as the ornament. It indicates that the current color of the city is dark. In addition,the yellow-red tones in Changsha are mainly used in the facade of residential buildings,low-rise commercial buildings and traditional commercial blocks,and the blue-green tones are mainly used in the facade of modern commercial high-rise buildings and low-rise commercial buildings. The use of multiple colors in the same space results in the confusion of architectural colors in the space. Based on the characteristics of the current situation of urban color in Changsha,the optimization methods of urban color analysis are discussed.
