Full textMicro-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

Full textComputer Aided Geometric Design (CAGD) which allows us to design the physical objects from mathematical models is used in many sectors of industry. It is currently a general wish to take advantage of the two these approaches rather than the antagonists : The goal that the continuous geometric model creates the continuous objects represented by the modelof the surfaces B-splines or NURBS) and the discreet geometric model made by eitherthe meshes or the subdivision surfaces. This duality of the approach has many potential industrial applications and therefore submits interesting significant science. The polyhedral surfaces and the subdivision surfaces in particular which offer the intrinsically discretization,are a very simple manipulation, but they do not replace the surfaces B-splines or NURBS.The works presented in this thesis aim to the reciprocal passage from a parametric surfaceto a polyhedral surface. We are more specialy interested to subdivisions surfaces considering as a liaison between the polyhedral surface and the parametric surface, because after a few steps of subdivision, the polyhedron characteristic converges to a parametric surface corresponding.We have proposed the schemas of the inverse subdivision allowing recreating the polyhedral surface coarse of subdivision precedent. We thus presented two methods for there construction of a parametric curve/surface : one for using the schema of uniform inverse subdivision and the other for non-uniform inverse subdivision. To improve the results of reconstruction by the inverse subdivision methods, we associate these methods with the process of adjustment the approximation which allows reducing the error of reconstruction.The results obtained have been compared with a well-known least squares method. Our methods are very promising in terms of approximation and compression

Full textThe study of surface appearance by photometric analysis is an active area of research, with various applications concerning the analysis of surface roughness or appearance ... The subject of this PhD dissertation relates to the study of opaque surfaces, through the acquisition of their geometry. Our study leads us to an analysis of mathematical reflectance models, for representing materials appearance. To provide a physically plausible description of opaque surfaces, the first major contribution concerns the implementation of a model based on Lambertian interfaced microfacets. This model generalizes several approaches often referenced in the literature, and includes flat diffuse or specular surfaces as well as diffuse or specular microfacets with three physically-based parameters: color, roughness and refractive index. It makes it possible to take into account the transmission of the light flux entering below the surface as well as multiple reflections between microfacets, while handling backscattering and anisotropy. The second main contribution of this work concerns the impolementation of a complete acquisition system for estimating geometry and reflectance from HDR images. Our methodology is based on a complete and automatic reconstruction framework, achieving a higher level of precision, a lower cost of implementation and a shorter processing time compared to photometry-based existing methods
