面向电力变压器虚拟装配的多感官融合交互方法

Multi-sensory Fusion Method for Power Transformer Virtual Assembly

虚拟装配技术旨在真实还原设备和物理场景,在真实环境中人们可以通过视觉、听觉、触觉等多种感官与物理世界进行信息交互。针对已有虚拟装配系统的真实感受限于单一感官人机交互方式的问题,提出一种多感官融合的信息交互方法,以提升沉浸感和操作性。提出一种在待装配体零部件体积差异性大的情况下的改进八叉树AABB包围盒碰撞检测算法,提升计算精度的同时极大减少计算量。实验结果表明:该方法在提高操作性和沉浸感方面有优越性。

Virtual assembly technology is to truly restore the equipments and physical scenarios. In the real world, people can interact with the physical world through visual, auditory, tactile and other sense organ. Aiming at the existing virtual assembly system being limited the single sense human-computer interaction mode, so a multi-sense fusion information interaction method is proposed to improve the sense of immersion and operability. An improved AABB Octree bounding box collision detection algorithm of large size diffidence component to be assembled is proposed, which can greatly reduce the amount of calculation and improve the calculation accuracy. The experimental result verifies the operability and the sense of immersion improvement.
