Course detail

3D Optical Digitization and Inspection of Machine Parts

FSI-ZRI-AAcad. year: 2018/2019

Students will be introduced to the theoretical part of the course with the basic principles and technologies of optical digitizing and their application in practice. They will be also familiar with digitization using optical system ATOS and TriTop functionality. In practical exercises, students will have the opportunity to experience 3D scanning of machine components and the subsequent adjustment of digital data. Within computer-aided exercises students will prepare semestral project focused on the application of gained knowledge in the field of digitization, editing polygonal data and reconstruction of surfaces.
The course has been upgraded with the support of the OPVK project. Project "The Studio of digital sculpture and new media", reg. No. CZ.1.07/2.2.00/28.0278, is co-financed by the European Social Fund and the statebudget of the Czech Republic.
