Title-deeds of tomb plots provide valuable historical records reflecting the social and historical context of their time. However, these artifacts often suffer from deterioration such as paint peeling, weathering, and discoloration, which can obscure important information. To address this, a digital conservation method combining close-range photogrammetry and hyperspectral remote sensing was proposed. First, close-range photogrammetry was used to generate a true-color orthophoto of the title-deed. Then, minimum noise fraction rotation was applied to identify characteristic bands in the hyperspectral images. Combined with the orthophoto and manual interpretation, faded patterns and texts—difficult to distinguish with the naked eye or standard digital photography—were extracted. Spectral matching and manual interpretation were also used to infer the types of pigments present. Results show that hyperspectral imaging could extract more hidden information compared to visible light photos, enriching our understanding of the title-deeds. This technique offers a new approach to the preservation, study, and interpretation of these fragile documents.
