Reverse Engineering Of Guizhou Minority Material And The National Cultural Heritage Protection And Development Of Technology

Guizhou is the province which more than nationalities live together, various national history is glorious, the culture enhances one another's beauty gorgeously, these rich cultural heritage have the Guizhou national minority characteristic is the Chinese nation cultural heritage essences, also is the precious wealth which only cannot replace, cannot renewably, cannot reappear. Along with society's development and technical progress, the West greatly of propulsion, economical globalization, tourism development, these long brilliant cultural inheritance just face the embarrassing situation that will soon disappear, because of the erosion of the nature changes, Artificial destruction and the protection means of fall behind.The reverse engineering making use of the 3D digitization equipment, accurately and fast measure the three dimensional coordinates points on the surface of object which is the existed components or prototypes, in kind which has, and through the three dimensional geometry modelling method reconstruction material object CAD model process. It is one new design method. This article has applied the reverse engineering technology in the Guizhou national minority material cultural heritage protection and the development research, and has carried on the Guizhou national minority material cultural heritage protection and the development engineering research.The reverse engineering key technologies includes: Data acquisition, data processing and model reconstruction. This article has comprehensively analyzed the theory and each research technique which these key technologies apply, has investigated and studied Guizhou national minority material cultural heritage present situation, and has selected the place play mask and the carved stone bird which have the Guizhou national minority material cultural heritage characteristic as the research sample. Under the reverse engineering research foundation, using the three dimensional laser scanner to obtain the three dimensional point cloud data of the entity, using the reverse engineering software Geomagic Studio 8.0 to carry on the data processing, obtained the entity three dimensional image, again using the Rapid Prototyping equipment to obtain the original entity which the traditional method is unable to reappear precisely.The research indicated utilizes the reverse engineering the Guizhou national minority material cultural heritage in the protection and the development, opened a new mentality in the material cultural heritage protection method. The research results had the vital significance to the Guizhou national minority material cultural heritage protection research, to enhanced the Guizhou traveling product the development speed, promotes the Guizhou tourism development to have certain serviceability.
