Quantitative Research On Visual Aesthetic Evaluation Of Single Tree Based On Psychophysical Method

The 5G era is coming,and artificial intelligence has gradually emerged in people’s daily lives."Alpha Dog" has won a lot in the field of Go."Microsoft Xiaobing" won a lot at the International Textile Fabrics Autumn and Winter Expo after publishing poetry collections.Although the public opinion that "human beings will be replaced by artificial intelligence" has brought a certain degree of controversy and debate,the current artificial intelligence technology is not a miracle product that appears in literary works.The essence of it is only to humans.There are still a lot of shortcomings in the functional content of artificial objects constructed by intelligent imitation.To truly realize the projection of human intelligence function,we must first transform the subjective and perceptual content in the human brain into objective and rational data and algorithms that can be recognized by the machine,and put it into the huge database behind artificial intelligence.If artificial intelligence is needed to complete the garden design work,the research and formulation of its related data algorithms will become an indispensable preparation.Therefore,based on the framework of psychophysical research methods,this study studied the evaluation index system,process and method of the visual ornamentality of individual trees.For many years,as a soft material in garden landscape design,plants are indispensable.To create a high-quality garden plant landscape,it is necessary to properly evaluate the existing garden plant landscape and summarize the experience,to determine what kind of plant landscape can be called a high-quality plant landscape.But so far,the visual evaluation of landscape plant landscapes and all landscape visual evaluations are still based on fuzzy random subjective evaluations,and an objective and scientific quantitative system evaluation system has not yet appeared.In view of this,this study selected Phoenix Tree in the urban area of Haikou City as the research object,using psychophysical methods as the frame structure,and refined the objective indicators that have a certain influence on the visual ornamental evaluation of individual trees,and refined to specific Factors and implementation methods.The four indicators are volume,visual complexity,color richness,and seasonal phase richness.The seven influencing factors are plant height,crown width,breast diameter,visual entropy,color richness index,hue,and shape.Then use the SD method to obtain the subjective evaluation results of the tree samples and verify the validity of the relevant indicators through correlation analysis.Quantitative analysis of the objective index values of the tree samples,and finally a regression analysis of the subjective and objective evaluation results,judging that there is a logarithmic relationship between plant height,crown width,breast diameter and body volume,there is a linear relationship between visual entropy and visual complexity,and rich colors There is a power function relationship between the degree index and the color richness,and a logarithmic relationship between the hue and the seasonal phase,all in line with the classic functional formula of psychophysics.According to the research results,a new method based on the psychophysical method framework and with good ordering,which can quantitatively evaluate the visual appreciation of individual trees is established.
