高精度定位技术是实现交互式游戏等细粒度定位服务的基础。提出了一种新的定位系统Dragon，该定位系统能够以10Hz的刷新率提供厘米级的定位精度。Dragon使用伪点滤波算法处理非视距测量，使用扩展卡尔曼滤波（EKF）处理测距检测误差和测距噪声。此外，从龙获得的高精度的位置流被利用为基于位置的控制，通过识别运动目标的姿态。特别是龙和手势识别系统的设计方法，建立和性能评估。
High precision localization technology is the basis of fine-grained Location-based Service (LBS), such as interactive games, etc. A novel location system named Dragon is proposed, which provides target location in centimeter-level precision with 10Hz refreshing rate. Dragon uses a Fake-spot filtration algorithm to deal with the NLOS measurements and uses Extended Kalman Filtering (EKF) to handle the mistake of ranging detection and the ranging noises. Further, the high accuracy location stream obtained from Dragon is exploited for location-based control via recognizing the gesture of a moving target. Particularly, the design methodologies, establishment and performance evaluations of Dragon and the gesture recognition systems are presented.
