SIRG: "Being There": User-centric Wireless Image-based Sensor Networks

点击翻译按钮获取中文摘要

This Sensor proposal focuses on addressing the limitations of large scale wireless networks ofimaging sensors, namely limitations of sensor power and network bandwidth and human limitationsin the capability to absorb and integrate large amounts of image data. The ideal system providesthe user with an integrated view from the multiple imagers, providing the feeling of being therealong with the capability to navigate the space while allowing the network to run unattended forlong periods of time. Achieving these goals requires a cross-layer design that encompasses all levelsfrom the application to the hardware.Intellectual Merit: We propose developing adaptable low power imagers, distributed imagefusion algorithms, and an overarching sensor management protocol. The imagers will be able tocapture scenes with adaptable resolution, both spatially and in terms of image bit-depth, andperform compression for a fraction of the power required by existing systems. To present theimage data to the user in a more integrated fashion, we will develop image mosaicking algorithmsthat work with uncalibrated cameras and non-planar scenes. Finally, we will develop intelligentsensor management techniques that use application-level information to appropriately configure thesensors and the network itself.Broader Impacts: (1) Providing a being there experience will have a profound impact ondistance-based viewing applications, from surveillance to tele-presence. (2) The PIs are committedto training students and will integrate this research with their teaching. (3) The cross-disciplinarynature of this research and the potential for high societal impact will hopefully attract studentsfrom under-represented groups. (4) The PIs will develop a sensor network tutorial and use thiswith the demonstration image-based sensor network to spark the interest of the community in thisexciting field of study.
