报告题目：
Geodesic reconstruction from orientation data and G2-Hermite interpolation on the sphere.

报告摘要：
The general topic of this presentation focuses on the acquisition and reconstruction of physical surfaces by mean of a ribbon device equipped with micro-sensors, providinggeodesic curves running on the surface. The whole process involves thereconstruction of these 3D ribbon curves together with their global treatmentso as to produce a consistent network for the geodesic surface interpolationby specific filling methods based on Coons-like approaches. This problem of reconstructing surfaces from unstructured orientation data is clearly ill-posed. However, our previous works allowed us to set up a valid reconstruction protocol.So as to be optimal, the ribbon curve reconstruction has to integrate the orientation informations provided by the sensors in their entirety, as well as the mechanical properties of the ribbon that force it to follow geodesic curves on a surface. This last point will be at the heart of this talk.
