主 题:Underground space Visual comfort Measurable evaluation Machine learning
摘 要:Based on human perception and machine learning methods,this study proposes a measurable method for evaluating visual comfort in underground ***,a comfort evaluation index based on the characteristics of human visual perception is proposed,and color features and segmentation extraction methods for intelligent methods are ***,using probability statistics and machine learning methods,a multi-class intelligent sorting and classification algorithm for ranking visual comfort levels is constructed and a comparison is made of the suitability of different intelligent methods for evaluating visual *** random forest algorithm is then selected as the most effective measurable intelligent evaluation algorithm for underground ***,the proposed method is compared to intelligent methods employed by previous research,and a case study,the Wujiaochang underground space in Shanghai,China,is applied as the *** show that the proposed method can effectively improve the quantification and refinement of human perception and evaluation of comfort in underground spaces;this method will also be useful in computer-aided generative design in the future.
