摘要: 介绍了一种基于双机同步的desktop虚拟现实设备的复杂产品虚拟装配仿真系统,对系统的人机交互技术进行了深入研究,提出了一种基于SOP(Structure of Parts)数据结构的属性类驱动算法的产品信息管理技术以及模型转心匹配法,阐述了一种适用于多部件多场景的、快速的基于扫描线技术的直接操纵交互算法原理,通过系统的实现验证了算法的实用性与效率,有效地提高了系统性能与扩展性.

Abstract: Based on the dual computer synchronized desktop virtual reality equipment, a virtual assembly system for the complex products was introduced. The human-computer interactive technology in the system was studied. The product information management technology was proposed on an algorithm of the SOP (structure of parts) data construction which acted on the attribute class for driving. The DOF (degree of freedom) law for matching the rotation center of models was presented. A direct and fast control interactive algorithm principle which was suitable for the multi-parts and multi-scenes grounded on the LOS (line-of-sight) technology was discussed, and the usability and efficiency of the algorithms were verified through the system realization. It is proved that the performance and extension feature of the system were promoted obviously.
