摘　　要：目前增强现实中的虚实遮挡算法大多数是一般性方法,缺少相关文献针对虚拟装配的特点研究增强现实装配中的虚实遮挡问题。分析了增强现实装配场景中虚实零件、装配特征、上下文导航等元素间的遮挡关系,提出了针对增强现实装配的虚实遮挡方法。原型系统试验证明该方法能够有效解决增强现实装配中虚实遮挡问题。Recently most occlusion handling method in augment reality are general algorithms,more special research on occlusion handling with in augmented reality assembly application is required.Occlu-sion between the virtual/physical parts,visual assembly features and context information in augmented re-ality assembly are analysed,an occlusion handling method aimed at augmented reality assembly is pre-sented.The method is implemented in augmented assembly prototype system and is proved to be efficient in handling the virtual/physical occlusion in augmented assembly.
