Abstract:Multi-camera network is a visual sensor network in which cameras are communicated each other to achieve complicated tasks. The effective coverage of the target objects among cameras is critical in order to make the collaborative camera network operate appropriately. Solicitation of solutions to problems such as optimal visual sensor deployment and sensor selection /planning etc, calls for quantitative models for camera behaviors in a network. In this presentation, a coverage model is first presented to describe the coverage feature of networked cameras. Applications are then presented to illustrate how the developed model could be applied to solve various optimization problems for a camera network. In particular, an optimal view planning example is presented for 3-D inspection and a graph-based optimal sensor deployment is also solved using the coverage model. Finally, a new tensor based camera model is proposed based on the idea of camera coverage. It is seen that the tensor based model is mathematically rich and is very sensitive to relative positions of cameras which offers great opportunities for more quantitative optimization on camera sensor network.
Biography: Xiang Chen received his Ph. D. degree in system and control from Louisiana State University in 1998. Since 2000, he has held cross-appointed positions in Department of Electrical and Computer Engineering and Department of Mechanical, Automotive and Materials Engineering at the University of Windsor and is currently a Professor in the Department of Electrical and Computer Engineering. He has made fundamental contribution to Gaussian filtering and control and to the control theory of nonlinear systems with bifurcation. He has also made significant contribution to industrial applications of control and optimization in automotive systems and in vision based sensing systems through extensive collaborative research and development activities with robotic and automotive industries. Some of the deliverables have been patented by relevant companies or became transferred technologies to relevant companies. He is currently an Associate Editor for SIAM Journal on Control and Optimization, a Technical Editor for IEEE/ASME Transaction on Mechatronics, and was an Associate Editor for the Journal of Circuits, Systems and Computers from 2004 to 2008. He received Research Awards (4 times) from the University of Windsor. His research has been well supported by research funds from government agencies at both federal and provincial levels in Canada and from industrial companies in both Canada and USA. He has published more than 100 papers in journals and conference proceedings. His current research interests include optimization and control (robust and optimal) of systems with complexities, graph-/game-theoretic approaches for complex networked systems, as well as applications to automotive control systems and robotic vision sensor networks. He is a registered Professional Engineer in Ontario, Canada.
