Research On Optimization And Verification Of Stereoscopic Lighting Of Independent Showcases In Museums

Stereoscopic lighting design research is a classification in museum lighting research.By adjusting the brightness of the light and controlling the ratio of the illuminance on different sides of the exhibit,it enhances the user's visual experience and attention.In recent years,due to factors such as the development of cultural heritage education and the promotion of Internet communication,entering museums has become a part of people's daily life,and research on museums has become more in-depth.Through the literature dynamic research and field visits,this paper summarizes problems such as stereoscopic lighting research vacancies,and practical application-based experience.According to the relationship between lighting,exhibits and viewers,combining the theory of Man-Machine-Environment System Engineering as the basis of research ideas,the author conducted the experiment with "safe,efficient,and economical" as the overall goal of the experiment.Design and test a psychophysical questionnaire for stereoscopic evaluation combining visual factors,user emotion,cognition,behavior,and subjective factors,and use them in subsequent experiments.Based on the theory of SOR stimulus response and visual attention selection theory as the experimental method,combined with virtual reality technology,this experiment takes ceramic ware as the research object,and designs a stereoscopic lighting research experiment of a single object based on a plane and a stereoscopic lighting verification of multiple objects based on VR experiment.The research results of the stereoscopic lighting research experiment of a single object based on a plane show that: the change of stereoscopic lighting effect mainly affects the viewer's visual and emotional changes.The smaller the volume of the exhibit,the less influencing factors;The rule is that the larger the area of the enclosure,the optimal stereoscopic lighting value will decrease.In this experiment,according to the law,the relationship between the area of the enclosure and the value of the best stereoscopic lighting effect is summarized.The results of the stereoscopic lighting verification of multiple objects based on VR experiment show that: before and after the optimization of the stereoscopiclighting,the viewers' positive emotions and attention to the exhibits are significantly improved;after the optimization of the stereoscopic lighting,the viewers are more inclined to pay attention to the details of the exhibits,followed by the shape and color.In this study,two experiments were conducted to explore the subjective influence of stereoscopic lighting changes on viewers,and the factors of viewers' tendency to pay attention to exhibits.We have proposed stereoscopic lighting numerical quantification standards and design guidelines to help practitioners refine lighting in applications so that it can improve the visual experience.We put forward a new questionnaire and a new stereoscopic research method,which provide ideas for subsequent related stereoscopic lighting research.
