Abstract
Abstract. Aiming at solving the problem of how to obtain the different evidence and deduce the disappeared sections of the Great Wall site, this paper quoted the concept of evidence scale and proposed a virtual restoration framework. In this paper, taking the Nine-eyes watchtower as an example, we modified the evidence-scale from 10 to 3: the existed relic, the direct evidence and the indirect evidence. The framework consisted of three parts, namely, the classification of evidence scale, the evidence checks and the generation of three-dimensional (3D) virtual models. Base on the support of the restoration scheme and 3DMAX technology, the disappeared parts of Nine-eyes watchtower was finally restored to its original appearance. The result of virtual restoration could not only help the tourists to visit the original appearance of cultural heritage, but also experience the culture value and historical vicissitude. Therefore, it was of great scientific significance and cultural value to study how to carry out virtual restoration for the ancient relics.

Summary
The Great Wall with a history of about 2,700 years was one of the most impressive cultural heritages and was well known as one of the greatest wonders in the world. The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, Volume XLVI-M-1-2021 28th CIPA Symposium “Great Learning & Digital Emotion”, 28 August–1 September 2021, Beijing, China and the promotion of the data processing(Pesci et al 2012; Pritchard et al 2017; Li, Zhao 2018), the digital technology played an important role in the protection of the the Great Wall and several researchers have developed a consensus on using this type of methods to promote the protection work for the Great Wall. With the development of the survey technology and computer science, the digital restoration would constitute a long tern support for the spread of Great Wall culture. How to deduce the disappeared sections of the Great Wall should be another key issue to consider. This was because the virtual restoration involved different aspects of the evidence type
