3D Accurate Location Stream Tracking and Recognition Using an Ultrasound Localization System
نویسندگان
چکیده
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.

MonoStream: A Minimal-Hardware High Accuracy Device-free WLAN Localization System
Device-free (DF) localization is an emerging technology that allows the detection and tracking of entities that do not carry any devices not participate actively in the localization process. Typically, DF systems require a large number of transmitters and receivers to achieve acceptable accuracy, which is not available in many scenarios such as homes and small businesses. In this paper, we intr...
متن کاملHigh-accuracy ultrasound target localization for hand-eye calibration between optical tracking systems and three-dimensional ultrasound
Real-time target localization in ultrasound is useful in many clinical and scientific areas. For example in radiation therapy tumors can be localized in real-time and irradiated with a high accuracy. To measure the position of an ultrasound target in a global coordinate system or to extend the tracking volume by moving the ultrasound transducer an optical marker is attached to it and observed b...
متن کاملA Hierarchical Face Behavior Model for a 3D Face Tracking Without Markers
In the context of post-production for the movie industry, localization of a 3D face in an image sequence is a topic, with a growing interest. It’s not only a face detection (already done!), but an accurate 3D face localization, an accurate face expression recognition, coupled with the localization, allowing to track a real “living” faces (with speech and emotion). To obtain a faithful tracking,...

A sensor network consists of a large number of sensor nodes that are distributed in a large geographic environment to collect data. Localization is one of the key issues in wireless sensor network researches because it is important to determine the location of an event. On the other side, finding the location of a wireless sensor node by the Global Positioning System (GPS) is not appropriate du...
