What is the background of the project?
The Institute for Evolutionary Medicine is an leading international and globally connected research, teaching and service institute which is part of the medical faculty of the University of Zurich. Following our mission statement "Learning from the past for the present and the future", we analyse ancient biological material and associated data to better understand modern human health issues and diseases. One of our core research areas is the application of modern clinical and experimental imaging techniques to ancient human remains for diagnostic and documentation purposes. Photogrammetry designates a technique to obtain reliable information about physical objects by recording, measuring and interpreting photographic images. Nowadays, photogrammetry allows to create high-resoultion 3 d4imensional models trough multi-stage photogrammetric data processing. Photogrammetry is currently used in bioarchaeological research for excavation documentation as well as for the documentation of cultural heritage. However, its potential for diagnostic applications for the study of pathological features in ancient human remains is still widely unexplored. Non-invasive, yet diagnostically valid, analytical methods are highly desirable for valuable and often unique ancient specimens.
What is the aim of the project?
In this project, using photogrammetry, participants will capture several reference objects from our Institute's paleopathological collection and experimentally determine optimum parameters for generating diagnostically valid 3D models.
What techniques and methods are used?
- Acquisition of photogrammetric raw data. - Adjustment and modification of acquisition parameters. (for example specimen positioning, number of images, illumination, and background) - Post-processing of raw data using specialized computer software. - Evaluation of fidelity in terms of diagnostically relevant macroscopic features. - Reporting of results in a short presentation.
What is the role of the student?
- The tasks of the student will be performed on his/her own
- The tasks will be done under supervision
What are the tasks expected to be accomplished by the student?
- Acquisition of photogrammetric raw data, using professional photographic equipment. - Adjustment and modification of acquisition parameters. (e.g. specimen positioning, number of images, illumination, and background) - Post-processing of the aquired raw data using specialized computer software. - Evaluation of fidelity in terms of diagnostically relevant macroscopic features in collaboration with researches of our Institute. - Reporting of results in a short presentation.
Will there be any theoretical teaching provided (preliminary readings, lectures, courses, seminars etc)
Practical teaching shall be done “on the job”. Furthermore time will be given to read selected literature on the topic. Participants will be assisted for the evaluation and presentation of their results.
What is expected from the student at the end of the research exchange? What will be the general outcome of the student?
- The student will prepare a scientific report
What skills are required of the student? Is there any special knowledge or a certain level of studies needed?
- Interest in working with ancient human remains. - Enjoy working with professional photographic equipment. - Patience and care during data collection. - No worries about using specialised computer software.
Are there any legal limitations in the student’s involvement
No
