贵州傩面具数字化及增强现实技术研究

为保护与传承傩文化与傩面具,构建了一套基于移动端的傩面具增强现实系统。通过快速建模工作流、贴图纹理优化与特征增强算法,实现了傩面具的逼真还原。采用改进的ORB算法对图像特征点检测和匹配,并利用EPnP算法快速匹配当前视角接近的参考图像,确定虚拟模型在真实场景下显示的位置方向。提出的方法,能够在实际场景中对傩面具进行高仿真三维渲染与管理,并完成了移动增强现实系统在安卓手机上的验证,满足了移动性、精确性和实时性的要求。

Digitization of Guizhou Nuo and Its Augmented Reality Technology

In order to protect and inherit the Nuo culture and masks, a set of enhanced reality system of Nuo masks based on the mobile end is constructed. Through fast modeling workflow, texture optimization and feature enhancement algorithm, the realistic restoration of Nuo masks is realized. The improved ORB algorithm is used to detect and match the image feature points. With the EPnP algorithm, reference images close to the current perspective are quickly matched, and the location of the virtual model in the real fusion reality is determined. The proposed approach can realize a high-fidelity 3D rendering and management of Nuo masks in the actual scene and complete the mobile augmented reality system validation on android phones, satisfying the requirements of mobility, accuracy and real time.
