-
摘要: 针对目前虚拟装配系统交互性差、操作感不强等问题，基于增强现实技术研发一种虚实交互AR装配系统。以减速器拆装为例，结合碰撞器与分离轴定理设计的模型间碰撞检测方法，减少在线计算工作量，可实现快速动态装配仿真；基于图像识别提出的触发式脱卡识别方法，解决了传统脱卡识别过程中虚拟模型位置不可控的问题。实验结果表明，该系统不仅能够实现实时虚实交互的装配仿真，而且增强了装配的交互性和操作感。Abstract: Aimed at the problems of poor interactivity and weak operational experience in current virtual assembly systems, a virtual and real interaction AR assembly system is developed based on augmented reality technology. Taking reducer disassembly as an example, combining collider and separation axis theorem, the collision detection method between models was designed to reduce online calculation workload and realized fast dynamic assembly simulation. Based on the image recognition, the triggered detachment recognition method solved the problem that the virtual model position was not controllable in the traditional detachment recognition process. Experimental results show that the system can not only realize real-time virtual real interaction assembly simulation, but also enhance the assembly interaction and sense of operation.
