摘　　要：针对藏式传统建筑色彩艺术分析中以定性分析为主、缺少定量分析的问题,首先介绍了视觉可分函数、色彩可分度、色彩特征张成空间等相关定义,然后给出了以简单集合运算为主要理论依据的藏式传统建筑中色彩特征张成空间的生成方法,将其结果作为藏式传统建筑彩色特征的主要表现形式,最后将数码照片和彩色点云作为验证数据集,利用Matlab编程实现。实验结果证明了该方法的正确性与有效性,而且与已有的定性分析结果一致。This article is focused on the qualitative analysis in the color art analysis of Tibetan traditional architecture（TTA）which is lack of quantitative analysis,the definitions of visual distinguishable function,color distinguishable level and color vector spandistinguishable space（CVSDS）are introduced firstly,method for CVSS is put forward by these definitions and simple set operation about Tibetan traditional architecture,which is used as the main manifestation of the color features of the TTA.Finally,numerical tests are implemented with the digital images and color point clouds being the inputed data set by Matlab programming.The experiments are proved that the method is simple,accurate and effective,and it agrees with the works of the existing qualitative analysis.
