Learning outcomes
The course aims to provide the knowledge and technical-scientific skills necessary for 3D data acquisition and reconstruction of human skeleton and mummified remains retrieved from archaeological excavations or museums, in order to create 3D digital models useful for further specific analysis, 3D printing, enhancement and exhibition. At the end of the course, students will learn to digitally acquire human remains using 3D surface scanner and to use software for post processing surface data and segmenting/visualizing image data from (micro)-CT sources, thus obtaining 3D digital models of the bones, which are essential for their restoration, analysis and exhibition.
Course contents
Introduction to 3D scanning: technologies and working principles; contact and non-contact scanning systems, reflective and transmissive systems; how to choose the 3D acquisition tool, technical considerations and device characteristics; scan protocol. Examples of 3D scans and digital reconstructions.
Introduction to post processing surface data: Geomagic Design X software workflow, set parameters and tools, import point clouds, point clouds alignment, noise cleaning, mesh generation; import meshes, healing defects, 3D model construction, save data, save project, export data; mesh editor, creating cutting planes, sections, curves and measurements (linear, angular, area and volume) of the digital models.

The course is based on lectures dealing with the program’s topics, coupled with practical training of 3D scan of human remains and post-processing of image data using dedicated computer programs.
As concerns the teaching methods of this course unit, all students must attend Module 1, 2 [https://www.unibo.it/en/services-and-opportunities/health-and-assistance/health-and-safety/online-course-on-health-and-safety-in-study-and-internship-areas] on Health and Safety online
Assessment methods
Student evaluation consists of a practical test articulated as follows: 1) align and merge the scans into a single mesh, 2) mesh optimization, 3) virtual restoration, 4) creation of 3D digital models useful for subsequent analysis, 3D printing, enhancement and 3D musealization. The student must show that he/she has acquired adequate general and systematic knowledge of the various topics and has mastered the scientific and methodological tools necessary for the optimization and creation of digital models of human remains.
Teaching tools
Lectures will be supported by power point presentations, osteological materials, 3D surface scanner, workstations with software for post-processing, segmentation and visualization of 3D image data.
