Recently most AR occlusion handling algorithms aimed at general environment, more special research on AR occlusion handling for application in the context of industrial assembly, such as assembly training and assembly task guidance, is required. An occlusion handling method aimed at video see-through AR-based assembly system is presented based on the analysis of the occlusion between virtual part, visual assembly feature, navigation information, physical part and physical assembly environment in the context of virtual/physical assembly working space. The method was implemented in prototype AR-assembly system and was proved to be efficient in handling the virtual/physical occlusion in augmented assembly scene.}, identifier = {05381422}, }
