Research On National Dynamic Art Display Based On Mobile Augmented Reality

National dynamic art,namely national dance,is an important part of China's intangible cultural heritage.The protection of national dynamic art has always been highly valued by our government.However,image recording and video recording have limitations in the protection of national dances,meanwhile mobile augmented reality is currently a popular technology.Therefore,it is of great theoretical significance and application value to promote the protection of national dances with the help of mobile augmented reality technology.In order to simulate the dance performance of real actors,this paper proposes a method of national dynamic art display driven by motion capture data.Moreover,in order to ensure the authenticity of the composite image of the mobile augmented reality system,this paper designs a method of implementing virtual and real occlusion based on virtual avatars and a method of generating flat shadow based on transparency blending.This paper also designs and realizes the national dynamic art display system based on mobile augmented reality,which achieves the purpose of expanding methods of national dance display.The research work of this paper mainly includes the following parts:(1)A method of national dynamic art display driven by motion capture data is proposed.This method not only effectively plans the motion path of the virtual character model,but also realizes the transition of the animation state of the virtual character model based on the animation state machine,thereby ensuring the fluency of the national dynamic art display.(2)A method of implementing virtual and real occlusion based on virtual avatars and a method of generating flat shadows based on transparency blending are designed in this paper.Furthermore,the virtual character model is superimposed on the real scene according to physical laws of the real world,which improves the authenticity of the composite image of the national dynamic art display system based on mobile augmented reality.(3)The system architecture of the national dynamic art display system based on mobile augmented reality is designed,which adopts layered design.The experimental results show that the method of designing the national dynamic art display system based on mobile augmented reality proposed in this paper can achieve the purpose of expanding methods of national dance display.Furthermore,the system designed in this paper is customizable,and the composite image has high authenticity.
