ToF-Data-Based Modelling of Skin Surface Deformation

Nowadays, the imaging techniques followed by advanced image processing algorithms become an indispensable part of diagnostic and surgical procedures. During recent years, an increasing demand for intra-surgical modalities can be noticed. The work aims at modelling the deformation of human skin surface caused by a navigated stick based on the point cloud acquired by a Time-of-Flight (ToF) camera. The data acquired by ToF and optical tracker are synchronized. Then, the skin deformation is modelled by applying a physics engine. The model evaluation is based on a Hausdorff distance. The results prove the applicability of the developed workflow.
