摘要
针对沉浸式虚拟维修人机交互中的位置追踪与动作耦合问题,研究并改进了高精度快速位姿估计算法,用于解决维修操作人员骨骼节点在空间中的位姿计算问题,实现了对操作人员的关键节点的位置追踪.研究了维修操作人员与虚拟维修动作之间的耦合技术,包括坐标变换、骨骼绑定以及改进型循环坐标下降算法驱动动作.研究并构建了某雷达设备虚拟维修训练系统,通过测试表明,位置追踪精度和动作的延迟基本能够满足沉浸式虚拟维修训练的需要.
According to the problem of position tracking and action matching for human-computer interaction in immersive virtual maintenance,a high precision and rapid pose estimation algorithm was studied to calculate the position and pose of the operator's skeleton precisely. Besides,a new method was studied to match the maintenance operator's action with the human body model's,which included coordinate transformation,bone match and improved cyclic coordinate descent algorithm. A virtual maintenance system was developed. Test results showed that the precision and time delay fulfilled the requirements of immersive virtual maintenance.
