摘　　要：亮度及亮度均匀度是影响人们对于光环境感受的两个重要的指标。新颁布的《城市夜景照明设计规范》JGJ/T163-2008也对景观照明的建筑表面亮度做出了相应规定,然而利用传统亮度计已经很难满足实际需求。本文着重对利用数码相机进行图像亮度测量中的相关误差源进行了分析。Luminance and luminance distribution are two important factors to affect the persons feeling of the luminous environment.The newly issued specification： code for lighting design of urban nightscape （JGJ/T 163-2008） also makes corresponding specifications about the building surface luminance in nightscape lighting design,but the traditional luminance meters hardly meet the practical requirements.In so in this paper we will focus on the error analysis of image based luminance measurement technology.

关 键 词：数码相机 图像亮度测量 误差分析
