Reconstruction de courbes et surfaces à partir de données tangentielles

Abstract : Micro-sensors developed at the LETI (like microaccelerometers or micromagnetometers) are able to give some information about their orientation. So if we put an array of sensors on a object, they will give data about the local tangency of the object. This work consists in reconstructing the shape of the object thanks to these sensors information. The shape can be a curve lying in a plane, or a space curve, and then a surface. Then we propose the motion capture of a shape in deformation, i.e. we will equip a curve or a surface with sensors, make movements and deformations with it, and reconstruct it in the same time via data from sensors. There is a lot of applications (medical, aeronautic, multimedia, hobbyist - do -it - yourself applications), and some materials will be experimented in the same time to test and validate these algorithms.
