摘　　要：高光谱仪作为一种无损检测方法,其"图谱合一"的特性使很多在正射影像上无法区分的类别变得可分。因此,本研究以清代张士保《论道图》为例,利用高光谱相机采集影像,经过最小噪声分离变换、主成分变换、掩膜等处理对画作的墨线进行了提取,实现了图像增强效果,并且发现了两处人眼无法识别的隐含信息。图像增强及隐含信息的发现对书画鉴定、修复提供重要依据,并开拓了新视野。Hyperspectral cameras can simultaneously collect high spatial resolution and high spectral imaging when used for making close-up photographs. As a nondestructive testing method,hyperspectral technology can make some indistinguishable patterns visible. In this article,hyperspectral camera was used to analyze a Qing Dynasty painting,Lundaotu（ ＂Discussion of doctrines＂） by Zhang Shi-bao. Digita land hyperspectral images were collected,using a model VNIR400 H camera. The image and the handwriting were enhanced by using MNF（ Maximum Noise Fraction）,PCA（ Principal Components Analysis） methods and a mask and finally a high-resolution image was created. As a result,it is found in this painting two hidden messages that could not be seen with the naked eye.

关 键 词：高光谱 图像增强 隐含信息
