影响汽车内饰光导主观均匀性判断的变量研究
Study on the Variables Affecting the Subjective Uniformity Judgment of Automobile Interior Light Guides
摘要
Abstract
The uniformity of direct-illuminated light guides directly affects the user experience.To deeply analyze the variables that influence the subjective uniformity judgment of light guides in the automotive interior environment,this study conducted research and analysis on three characteristic parameters,namely the number of LEDs,luminance tolerance and the luminance at the center of the light guide.Based on image simulation and subjective evaluation experiments,the results revealed that when the number of LEDs increased from 40 to 60,the uniformity score increased by 9.2％;when the tolerance was relaxed from 0％to80％,the uniformity score decreases by22.6％;when the center luminance was adjusted from10 cd/m2 to 2 cd/m2,the uniformity score decreased by 11.5％.In addition,the 丨Δu'丨 and 丨Δv'丨 color coordinates are negatively correlated with the uniformity score.This study reveals the intrinsic correlation between technical variables and user experience,providing a reference for product optimization.关键词
