Research On Digital Guide Method Of Ancient Architecture

In recent years,virtual reality technology has been gradually applied to all walks of life and achieved some results.In the cultural inheritance and tourism promotion,virtual roaming in ancient architectural scenes is of great significance to people's understanding of Chinese traditional culture and enhancing the attractiveness of tourist attractions.At the present stage,the industry mainly realizes the virtual roaming of ancient architecture scenes by setting up visiting routes artificially through threedimensional modeling of scenes;or lets users roam aimlessly in the scenes by themselves;in addition,it also displays the cultural knowledge of ancient architecture by artificially designing and generating the construction animation of building components.These methods depend on the subjective will of the programmer,or follow some inherent habits and rules in the relevant fields,while it takes a lot of time for practitioners to complete.Therefore,to design an automatic and excellent tour guide for ancient architectural scenes has become the main research objective of this paper.My main work includes:1)To meet the needs of users roaming in ancient architectural scenes,I proposed a path planning method based on image aesthetics quality assessment.Firstly,the raster method is improved with depth map,which can accurately get the travelable area in the scene.Then,the image quality in the view port is analyzed based on the triangulation rule of image aesthetics,and feedback to the path planning algorithm.Finally,the method is used to get the optimal scene roaming route.Compared with the traditional methods of map acquisition and path planning,it is proved that the average landscape quality obtained by this method is higher.2)A rule-based assembly sequence planning method for explosion maps is proposed in view of the characteristics of interconnection and constraints among components of ancient buildings.Firstly,the local explosion diagrams in each direction are generated according to the relationship between components;then the merged precursor sets of each component are generated;finally,the final assembly sequence is generated according to the merged precursor sets and the local explosion diagrams;in addition,the corresponding animation is generated through the final assembly sequence.Experiments show that this method can quickly and accurately get the explosion map of ancient buildings and generate corresponding animation.3)I Designed and developed a virtual tour guide system for Tibetan temples inShannan area,and used the above two methods to generate the tour route of the scene,as well as the explosion map and animation of the independent temples.The system realizes the combination of Tibetan ancient architecture culture and virtual roaming technology,and joins the automatic tour route with the best landscape,which makes users have better experience in roaming process.At the same time,it adds explosive maps and animation of related ancient buildings,which makes users have a deeper understanding of ancient architecture culture.
