摘要
目的:研究用数码摄影方法测量纯钛试件表面色彩的可行性与效果。方法:采用CIEL*a*b*颜色系统,在标准光源下应用数码摄影测色法和分光光度测色法分别测量纯钛试件表面的色彩,对两种方法的测量结果进行比较和统计分析。结果:纯钛试件色彩的数码摄影测量结果与分光光度仪测量结果存在差异,但有相关性,其中CIEa*的相关系数为0.803,b*的相关系数为0.782,L*的相关系数为0.825,它们之间的平均色差为3.14。结论:数码摄影与计算机技术相结合是一种新兴的色彩测量方法,钛试件色彩的数码摄影测量结果与分光光度仪测量结果具有高度相关性。
Objective： To evaluate the feasibility and effectiveness of digital photogralphy in measuring color of pure titanium specimen. Methods： Two methods were used to measure color of Pure titanium specimen under standard light source：digital photography and spectrophotometry, The results were compared and analyzed statistically. The color system was CIEL＊a＊b＊. Results： There was difference between the measuring results obtained from digital photography and that from spectrophotometry, and significant correlation was also found between them.The correlation cocfficent of CIEL＊, a＊, and b＊ was 0.825,0.803 and 0.782 respectively. The mean color difference between them was 3.14. Conclusion： Digital photography combined with computer technology is a newly developed color measuring method.The color measuring results of pure titanium specimen by digital photography correlated with that by spectrophotometry highly.
