Abstract

                                           The work in this Project involves Development of a Mobile Locationing  System Using a Wireless Network. That is capable of Estimating Position of a Person and Streaming Video over the Wireless Network. This system can also be used Inside a Building (Indoors) without the need of any external Infrastructure Inside the Building.The system uses multiple sensors like Camera and Inertial Measurement Units. All these modules are connected to the BeagleBoard-xM. The BeagleBoard-Xm collects data from these sensors , processes it and then transmits it to the local station over Wireless Network. The Camera can be placed inside the Helmet and the Inertial Measurement Unit (IMU-OpenShoe) is placed inside the shoe of the Person whose Position is to be Estimated. The Video Stream from Camea is compressed on the BeagleBoard-Xm DSP and Transmitted over Wireless Network to the local host. The IMU is based on the work done under the Project OpenShoe. With the help of IMU we get the position and velocity Estimates, which are then Transmitted over Wireless Network to the Local Station. The main aim of the project is to build a working system that will have the camera Video Codec Running on the DSP Processor of BeagleBoard-Xm and IMU, Working together and transmit the compressed Video stream along with the IMU data (Position and Velocity estimates) to the local station Over Wireless Network. At Local Station, Extracting the Position Data From Received Data Format over Wireless Network,  plotting Position of  a Person on GNU Plot.  IMU Data Streaming over Wireless Network Done by TCP/IP Socket Programming.

Development of the Project First Res-ponder System involves Estimation of Position and Video Streaming In Indoor Environment. System Integrated With BeagleBoard-Xm Board, Video Capture Device, IMU And Wireless Connectivity Modules. Video Compression Done BeagleBoard. IMU gives the Position and Velocity of First Res ponder. BeagleBoard-Xm Collects Data From IMU and Video Capture Device, Process It And Transmit Over Wireless Network.
