Through-Wall Vision Project Financement : FEDER / ANR
Bruno Lescalier, engineer, 09/2010 - … • Prototyping and Software development, participation in research. • Projects : • MODECOL : automatic recognition of grass. • Throught-the-wall : Imaging, reduce of noise, target detection,…
Team « Through-The-Wall Vision» • Recent structure in L3i: 2004 • With : • 2 Professors (M. Ménard, G. Louis) • 2 Lecturers (A. Gaugue, J. Khamlichi) • 2 PhD (O. Benahmed, X. Zhao) • 3 engineers (B. Lescalier, O. Chappe, V.Merelle) • Areas of expertise : • UWB (Ultra Wide Band) pulse device. • Signal processing : expertise in inverse filtering, deconvolution, decompositions,… • Processing and computer graphics / 3D. • Ongoingproject FEDER (2010/2011) / ANR (2011/2013)
Objectives of the Project • Development of a portable prototype : • Reliable detection of human presence in the building and enumeration. • Location kidnappers / hostages. • Tracking people movements. • Outline of the topology of place. • Detection of people in rubble.
