摘　　要：岩画是古代先民生产、生活、祭祀等活动的生动记载,是人类文明的史诗,岩画的断代一直是岩画研究的难点,文中提出了一种基于色度、饱和度和灰度(HSI)彩色模型的数字图像处理技术提取岩画灰度值(I)的方法,利用岩画灰度值与岩画作画年代之间的线性可比关系,测定岩画的年代。此方法能提取整个岩画中的灰度值,避免了手工提取有限个点的缺陷。试验结果表明此方法能为岩画的断代提供一种可参考的、简便的、快速的计算机解决方法,但测定年代的准确性依赖于选取的岩画标尺年代的准确性。Petroglyphs vividly record the production, life, worship and other activities of ancient ancestors. They are epics of human civilization. However, there are great difficulties in dating rock petroglyphs. In the paper, a method using digital image processing based on a Hue, Saturation and Intensity （HSI） color model is presented to date the petroglyphs. In theory, rock Intensity （I） is linearly correlated with the age of the rock and therefore can be used to date petroglyphs. This method can extract the rock intensity in the entire rock, which is much better than using a limited number of points by manual testing. The experimental results show that this method can provide a reasonable, simple and quick solution to the problem of dating rock paintings. It should be mentioned that the accuracy is dependent on the accuracy of the dating of the rock selected.
