ESTABLISHMENT OF QUANTITATIVE VALUE CORRESPONDING TO VISUAL PERCEPTIVENESS OF IRREGULARITY : Study on method for evaluating accuracy of finishing of tiled wall from a viewpoint of sense of sight (Part 3)

Abstract

lhe visual perceptiveness of irregularitsr of a tile on tiled walls was in fluenced by 【 he extent of irregularity and the species of tiled walls ， 1凪 he former report ， we presented the quantitative value ( Rmax )correspolldillg to the magnitude of human sense on irregtimlty ． In this paper ， based on the reEati ⊂ ) nship between Rrnax， the species of tiledwalls and the psycho 且 ogical scale re 垣 t血 g tovisual perceptiveness ， we established another q し tiヒ ative value ( AD wl 亘ch indicated the visual perceptiveness of irregu rity ． AI consisted of Rmax ， the 且 ength ofthe t鍾e ， the width of thejo 血 t and the luminance of the tiie andjoint ． Keywords ： ti' ed − att ， accuracy ' offinishing ， evat "ation method ， irregu ' arity ， visuatpercePtivene ∬ ， quantitative va ' ue
