增强现实环境下的产品装配引导技术

以增强现实环境下引导产品装配为目标，建立了面向增强装配过程的统一 信息模型，管理文字、几何和产品装配特征等可视化引导信息。采用基于标志物的视觉跟踪 技术实现虚拟零件和视频中真实零件的注册定位，通过建立虚拟和真实装配场景的深度图处 理增强装配场景中虚实物体的遮挡关系。利用虚实零件的注册位置把装配引导信息叠加到装 配视频场景中。并开发了演示系统，分析和说明了增强现实环境下引导产品进行装配的过程。

Product assembly guidance based on augmented reality

Aiming at the assembly guidance in augmented reality environment, an uniform augmented-assembly-oriented information model is build to manage visual text, geometric and feature information during assembly process in augmented reality environment. A marker-based tracking is adopted to realize the registration and localization of virtual and physical product part. The depth images of both virtual and physical scenes are used to handle occlusion between virtual and real objects in assembly process. The assembly guidance information is superimposed on the real time assembly video by using registration information of parts. A demonstration system is developed and the assembly guidance process is analyzed and described in augmented reality environment.
