Visual Evaluation System For Night View Lighting Of Pagoda

Due to the development of lighting technology,people's living standards have improved,the scope of activities and activities of the public at night have been expanding,and the demand for night lighting has also increased.Since 2000,many areas in China have been trying their best to improve the urban night lighting environment.In recent years,with the rapid rise of the night travel economy,urban night lighting has received unprecedented attention and importance,but at this stage for the city.Important architectural landscape nodes-the night lighting design of the ancient tower building is not mature enough,the research is not deep enough,the lighting effect can not meet the expectations of the public and the development requirements of the times,so this article has done a lot of experiments,obtaining a large amount of data and using advanced domestic and foreign The data analysis methods,construct,support and improve the whole evaluation system.This research is for the 2019 graduate student innovation ability training project in Hebei Province(Provincial longitudinal research projects,project number: CXZZSS2019079),aiming to form a scientific and reasonable pavilion-style Guta night lighting visual evaluation system.First of all,through the research literature,field measurement,software simulation and other means,this paper firstly investigates the current situation of the night lighting of the ancient tower building,and conducts a preliminary investigation on the key evaluation factors of the night lighting effect,and summarizes the application methods of the current evaluation system.Among them,the focus is on the classification of the pavilion-style ancient tower lighting performance and its simple visual comfort or rationality analysis through expert consultation,visual evaluation and other means.Secondly,on the basis of the above research,based on the nighttime light environment around the ancient towers in the city,select the simple and representative pavilion-type ancient tower main body,reasonably refer to the standard recommendation ratio and combine the actual requirements for the main body and background brightness.The brightness proportional comfort between the main structures is required to carry out the simulation visual evaluation experiment.The multiple linear regression analysis is carried out on the experimental data,and the reasonable brightness convex ratio analysis equation and the brightness proportionalinfluence analysis result are obtained.Then,based on the nighttime light environment around the ancient towers in the city,select the simple and representative pavilion-type ancient tower main body,reasonably refer to the relevant color temperature research and the actual excellent design case recommendation,combined with the above brightness highlighting research,the pavilion-style ancient The color temperature performance requirement is simulated visual evaluation experiment,and the evaluation data is constructed by C-SVM vector machine evaluation model.Finally,the reasonable performance requirement of the ancient tower body for color temperature conditions is obtained.After that,using the structural equation model,the pavilion based on the performance requirements of the pavilion-style ancient tower building,the visual brightness comfort feeling of the night scene,the visual color temperature suitability feeling of the night scene,and the lighting realization requirements are divided into four parts: Guta night lighting visual evaluation system.Finally,using the pavilion-style Guta night illumination visual evaluation system obtained in the above,the field questionnaire was used to construct the fitted model using BP artificial neural network,and the residual value of the fitting result was observed and the final result was compared with the initial evaluation.Value,observe whether the error value set by the model is met,in order to finally verify that the evaluation system is scientifically available.This paper uses literature research method,survey analysis method,simulation analysis method,"SD" method and linear regression analysis,C-vector machine algorithm,structural equation model,BP artificial neural network and other statistical methods to optimize the lighting performance of ancient tower buildings.Demand,nighttime brightness,demand,and lighting color optimization requirements were analyzed,and the nightscape lighting construction of the ancient tower building was strengthened,and the lighting effect of the ancient tower was optimized.It can reshape the city night image,increase the night vitality of the city,and let the ancient The tower "lives" on the basis of "preservation" and plays the role of the ancient tower in another dimension,showing the charm of Chinese ancient architectural culture and Buddhist culture,and complementing the research on the night lighting of the ancient pavilion-like buildings.A scientific and reasonable pavilion-style Guta night lighting visual evaluation system,in order to optimize the effect of the night lighting effect of the pavilion-type ancient tower building.
