Delaunay based method
OrthoProof @ LIME
I worked on a project at LIME as part of an internship for 8 weeks.
The project was about the realization of a 3D realtime scanner for a persons teeth and gums or denture.
The scan will produce a high-resolution 3D model enabling professionals to get instant feedback and visualization of medical treatments.
I was tasked to investigate different methods for quick and accurate normal and curvature computations.
The first method was based on Delaunay triangulation and gave good results however it was not fast enough for this application.
The final method was able to correctly calculate the normals of point clouds with up to 5000 data points in miliseconds.
