Modern high resolution 3D-measuring techniques are widely used in quality control and industrial production, because they allow precise and reliable inspection of objects. Their potential to monitor surfaces, however, must not be restricted to industrial objects. Also in cultural heritage applications a detailed and reliable spatial description of surfaces is often useful and opens up new possibilities for conservation, analysis or presentation of objects. In the actual work we have considered Buddhistic stone inscriptions (8th- 12th centuries) which are important cultural assets of China. They need to be documented, analyzed, interpreted and visualized archaeologically, art-historically and text-scientifically. On one hand such buddhistic stone inscriptions have to be conserved for future generations but on the other hand further possibilities for analyzing the data could be enabled when the inscriptions would be accessible to a larger community, for instance the understanding of the historical growth of Buddhism in China. In this article we show innovative techniques for the documentation and analysis of stone inscriptions located in the province of Sichuan - south-west of china. The stone inscriptions have been captured using high precision 3D- measuring techniques what produces exact copies of the original inscriptions serving as base for further processing tasks. Typical processing might be directed towards an improvement of the legibility of characters or may try to automatically detect individual letters, to automatically identify certain text passages or even to characterize the written elements with respect to a potential style of the monk or the executing stonemason. All these processing steps will support the interpretation of the inscriptions by the sinologists involved with the analysis and evaluation of the texts. The concept and features of the image processing applied on the captured inscription as well as the aims and the effect of an interpretation based on algorithms for identifying and analyzing the inscriptions are demonstrated. In order to present the outcome to a large community, the results of the stone inscription reconstruction, the done interpretation and additional 2D / 3D maps are published within an interactive web platform.
