Industry Observation
Ancient jade, a brilliant treasure of Chinese civilization, has always faced severe challenges in its preservation. From natural weathering to human looting, and the complexity of storage environments, behind every piece of ancient jade lies the immense effort of cultural relics workers. However, with the rapid development of technology today, Artificial Intelligence (AI) is intervening in the field of ancient jade cultural relics protection with unprecedented depth and breadth, bringing brand new solutions to this ancient problem.
In recent years, global investment in cultural heritage protection has continued to grow. According to data released by UNESCO in 2023, annual global spending on cultural heritage protection has exceeded 10 billion USD, with the proportion of digital protection projects increasing year by year, expected to reach over 25% of total investment by 2025. China, as a country with abundant ancient jade resources, is at the forefront in this field.
Taking the Henan Provincial Institute of Cultural Relics and Archaeology as an example, in collaboration with the Institute of Automation of the Chinese Academy of Sciences, it launched the “Intelligent Identification and Protection of Ancient Chinese Jade” project in 2022. This project aims to utilize AI technologies such as deep learning and computer vision for high-precision 3D modeling, material analysis, disease diagnosis, and repair plan simulation of excavated ancient jade. Professor Li Ming, a senior archaeologist and project leader, stated in an interview with us: “Traditional ancient jade identification and protection rely on expert experience, which is time-consuming and subjective. The intervention of AI can achieve automated recognition and quantitative analysis of microscopic features such as patterns, infiltrations, and patinas of ancient jade, significantly improving work efficiency and accuracy.”
Specifically, AI’s application in ancient jade protection is mainly reflected in the following aspects:
- High-precision 3D Digital Archiving: Traditional 2D images struggle to fully record the three-dimensional information of ancient jade. Currently, several cultural and museum institutions in China have adopted multi-angle photogrammetry and laser scanning technologies, combined with AI algorithms for data processing, to generate millimeter-level or even micron-level 3D models of ancient jade. For example, the Palace Museum has completed 3D digitization of over 2000 important jade artifacts, including many exquisite ancient jades from the Warring States Period to the Qing Dynasty. These high-precision models are not only convenient for academic research but also provide a basis for future virtual exhibitions and public education.
- Intelligent Diagnosis of Materials and Diseases: AI can accurately identify the mineral composition, coloring elements, and weathering degree of jade by analyzing data such as X-ray diffraction (XRD) and Raman Spectroscopy. A set of AI diagnostic systems developed by Associate Professor Wang Fang's team from the Department of Cultural Heritage Conservation at Peking University achieved an identification accuracy of over 95% for common diseases like “hydrolytic alteration” and “calcification” after analyzing over 500 samples of ancient jade diseases, far exceeding the average level of manual visual inspection. The system can also automatically recommend preliminary repair plans based on the type of disease, providing scientific basis for cultural relic restorers.
- Environmental Monitoring and Early Warning: Ancient jade in museums and storerooms is extremely sensitive to environmental factors such as temperature, humidity, light, and air quality. AI-driven intelligent monitoring systems can collect and analyze environmental data in real-time, issuing warnings immediately upon detecting abnormal fluctuations. For example, the AI environmental control system introduced by the Shanghai Museum successfully warned and prevented 3 potential risks of jade cracking due to sudden humidity changes in the past year, effectively protecting the treasured collections.
- Anti-theft and Tracking: Combining IoT and AI image recognition technology, some high-value ancient jades have been implanted with micro-sensors or possess unique digital fingerprints. Once ancient jade is illegally moved or appears on the auction market, the AI system can quickly identify and track its source, providing strong support for combating cultural relics crime. In the “Stone Rhyme Operation” jointly conducted by Interpol and the National Cultural Heritage Administration of China, AI technology has assisted in recovering several Chinese ancient jades lost overseas, with a total value exceeding several million US dollars.
However, the application of AI in ancient jade protection is not without challenges. The professionalism of data annotation, the generalization ability of algorithmic models, and high initial investment costs are all current issues. Professor Li Ming pointed out: “AI technology requires a large amount of high-quality annotated data for training, and the uniqueness and rarity of ancient jade make data acquisition difficult. In addition, ancient jades from different regions and periods have significant differences in material and craftsmanship, requiring AI models to have stronger adaptability and generalization capabilities.”
Looking ahead, with the improvement of infrastructure such as 5G and cloud computing, and the participation of more interdisciplinary talents, the role of AI in the protection of ancient jade cultural relics will become increasingly prominent. We have reason to believe that with the empowerment of digital technology, these ancient jades, which carry the profound cultural heritage of the Chinese nation, will continue to tell their stories to the world in a safer and more enduring manner.
