The Research On The Influences Of Visual Characteristics With Different Surface Treatments On Pine Wood

In this paper,we take the pine material as the research object,study the visual characteristics of the surface modified pine and its application in furniture design,and take the quantitative visual characteristic research method to study the surface modified pine sample.The visual physical and psychological properties of the surface modified pine bed were studied.Using the method of semantic difference,the visual psychological values of 42 surface modified pine samples were studied under natural light,cold light and warm light in three different light environments,visual psychological quantity and visual psychological value of 12 kinds of surface modified pine beds.The color of 42 pine samples before and after surface modification was measured,and the preference,visual psychology,vision of pine samples were analyzed.Based on cluster analysis,the visual psychological quantity was classified and studied,and the usability and reliability of visual characteristics were investigated.The main results are as follows:(1)in natural light,cold light and warm light,23、25 of 42 samples had higher preference scores,which were mainly concentrated in bleachingⅠ,bleachingⅡ,material,carbonization Ⅰ,carbonizationⅡ,tea cyan,light brown,brown.Black red brown and black brown samples.Samples of natural light and cold light tend to prefer matte materials and semi-matte materials,while warm light samples tend to prefer semi-matte materials.(2)the visual physical quantities(color)of the surface modified pine samples can be divided into the following four categories: in the first category,the values of L * is positive in the range of 20 ~ 30,and a*and b* are positive,The values of L* in the second type are both positive in the range of 80.0 ~ 90.0,and a*and b* are positive;In the third category,the values of L * is positive in the range of 48.0 ~ 58.0,a*and b* are positive,and those of the fourth category are positive in the range of 32.0 ~ 50.0.In the first category,the tonal angle is lower in the region of red tonal(R)to orange(YR),and the value of brightness is lower and the saturation is lower.The second kind of tonal angle is yellow.The light value is higher and the saturation is lower.The third kind of tonal angle is in the yellow(Y)area,the brightness value is higher,the saturation is high.The fourth kind of tonal angle is in the yellow(Y)region,the brightness value is low,the saturation is above the average value.(3)In natural light,cold light and warm light,42 samples can be classified into three groups by clustering.In natural light,class I samples have the highest degree of preference,and their visual psychological quantities represent simple and elegant,natural,modern,concise,delicate,simple,and light colored samples,which are located in low brightness and low purity yellowish white areas and medium wood colors.It is located in the region of low brightness,medium and high purity light brown to reddish brown.Class II sample has medium preference,and its visual psychological weight represents deep,classical,foreign,noble,rough,surface modification sample material color is deeper,located in low brightness,the visualpsychological quantity represents the vocabulary is deep,classical,foreign atmosphere,distinguished,rough,the surface modification sample material color is deeper,is located in the low brightness,Low purity dark reddish brown region;preferences of class III samples The lowest visual psychological amount represents warm,medium color,located in the bright,high purity of the bright yellow region.In cold and warm light,class I samples have the highest degree of preference,and their visual psychological values represent deep,classic,foreign,noble,rough,surface modification samples with deeper color and lower brightness.Low purity dark reddish brown area and medium wood color,located in low brightness,medium and high purity light brown to reddish brown area;Class II samples have moderate preferences,and their visual psychological quantities represent plain,natural,modern,concise,delicate and plain,The color of the sample is light,located in the low brightness,low purity yellowish white area;Class III samples had the lowest degree of preference,and their visual psychological values represented warm words and medium wood color,which were located in the bright yellow region with medium brightness and high purity.(4)in natural light environment,the experimental results are consistent with those of small samples.(5)in the cold light and warm light environment,the results of the verification experiment with the bed as an example are consistent with the results of the small sample study,and there is a slight difference in the classification of the lexical description of the visual psychological quantity,and the result of the classification of the visual psychological quantity in the lexical description of the visual psychological quantity is similar to that of the small sample.Only in the small sample study,the perceptual vocabulary of "foreign" of class I was found to be in class Ⅱ in the verification study,and the rest were consistent.
