摘　　要：基于数字图书馆的研究成果,提出了一种虚拟图书馆中飞行器逼真建模与虚拟装配方法。介绍了飞行器三维模型转换、模型编码压缩、真实物体表面材质反射属性的获取与建模等关键技术,在此基础上,介绍了航空设备虚拟装配任务的典型应用示范。研究与实践表明:提出的航空虚拟图书馆藏品逼真建模方法具有进一步改善三维数字化展示和用户交互式体验等方面的能力。给出了航空虚拟图书馆虚实融合及交互应用的工作展望。A method was proposed which could model and assemble an aircraft realistically in the virtual library. The research background and the infrastructure of the system were introduced. Some related key technique of this method were introduced in detail, such as the transformation of 3-D aircraft model, the encoding and compression of the model, and the reflection attribute extraction of real-world objects surface material. A demonstration project--virtual assembling of aircraft engine was constructed based on this method. Experimental evaluation shows it can enhance the effect of 3-D digital exhibition and the experience of user interaction. The future trend in this field was discussed.
