【摘要】 讨论了一种新型的基于超声波测距的高精度三维定位定向系统的原理与设计。这种三维定位定向系统采用波头计数与零交叉点检测的方法来提高超声波测距精度 ,并通过三角形方法来实现三点所在平面的位置与姿态。这种新型的三维定位定向系统具有精度高、成本低、易于安装、体积小、抗电磁干扰能力强、对光线不敏感、无电磁辐射等优点。本系统不仅可广泛应用于虚拟现实系统头盔和数据手套的三维定位定向 ,还可应用于机器人控制与定位定向和多媒体系统等领域。更多还原

【Abstract】 The principle and design of a high precise 3-D orientation and location system for headpiece and digital glove of virtual reality system are discussed in this paper .The system adopts the method of peak counting and zero-crossing points detecting to improve the precision and makes use of triangulation to get the location and stance of the surface including the three points.. This new 3D location system have a lot of advantages: high precision , low price , easy for installation ,small volume ,high capacity to resist the electric-magnetic interference ,robust to light fluctuation, no electric-magnetic radiation etc.The system can also be used for the control and location of robot and multi-media system etc.更多还原
