基于移动终端的增强现实虚实融合技术

摘要

针对传统移动增强现实系统中虚拟模型和真实背景之间存在较为明显的视觉差异，不能够给予用户良好的真实体验的问题。建立了一种在 Android 系统下虚实融合较为逼真的增强现实装配系统。该系统首先解决三维虚拟模型的解析、渲染、管理问题，然后研究了虚实融合场景图层的关系，最后完成整个系统的虚实融合场景的构建。采用该系统对齿轮油泵模型进行增强现实装配虚实融合场景的构建实验，结果表明：系统可以在真实场景中添加虚拟物体，并且显示结果逼真度高、沉浸感强，能够顺利完成对装配过程的指导。%Because of the obvious visual difference between the virtual models in the traditional mobile augmented reality system and the real background,it is not able to give the user a good authentic experience.An augmented assembly system in Android platform,which has a good integration of virtual and real scenes,has been established.The problems related to the resolution, rendering,management of 3D virtual models were solved first.Then the relationship between the layer of virtual and real scenes was studied.At last,the integration of virtual-physical of the whole system was completed.A construction of the scene of an in-tegration of virtual and real of gear pump model in the augmented assembly was built up by using the system.Experimental re-sults demonstrate that the system could place virtual objects in the real scene with an intensive immersion,and could provide a guidance for the assembly procession successfully.
