3D Data Processing

The research group 3D Data Processing focuses on R&D projects and customized development for acquisition, modeling, analysis and visualization of 3D and 4D surface and volume data, targeting related software and system solutions.

Naturally, technical and algorithmic tools resulting from such work are of interest for many purposes and sectors. They are successfully applied for quality control tasks in industrial applications, building surveying, restauration and documentation, in medical, dental and orthopedic engineering, ceramic or apparel industry as well as in art and culture.

The group 3D Data Processing group also organizes the well-established annual GFaI workshop 3D-NordOst (3D-NorthEast).
