Abstract: To address the issues of traditional green construction site evaluation methods that overlook subjective feelings and are difficult to present intuitively, the green construction site evaluation research was developed while safety, aesthetics, and efficiency were taken as evaluation dimensions, and a scoring website system based on the TrueSkill algorithm was then constructed to explore the application approach of visual subjective evaluation methods. The mentioned method was conducted by scoring 1500 images collected from two real construction sites by 106 respondents in terms of three evaluation dimensions above. On average, 16 sets of evaluation tests were completed by each subject, yielding a total of 4,086 evaluation data and the experimental data analysis through figure scores, scatter plots and frequency curves on Skill value, shows that the above research method based on visual subjective evaluation reached sufficient credibility. In addition, the ROI (Region of Interest) data collected in the above study can serve as the data foundation for the application research of computer vision in green construction site evaluation, and has reference significance for the study on computer vision in real-time supervision of green construction sites.
