Research on the Protection and Communication Strategy of Cangyuan Cliff Painting Based on Virtual Reality Technology

At present, the protection methods of Yunnan Cangyuan cliff paintings are mainly based on storage and shape protection. Because of the long history and various natural factors, the protection of Cangyuan cliff painting can not be well protected and stored; moreover, as a result of the reality factors that Cangyuan cliff painting has been damaged by many tourists, its integrity has not been as good as before, which has led the relevant departments to protect the cultural heritage. Many scenic spots of Cangyuan cliff painting have not been opened to the public, which has great influence on their transmission and inheritance. In this article, we used digital means to collect the original material of cliff paintings. First of all, we model it in three-dimensional and summarize the common patterns of cliff paintings.
