3D Optical Digitization and Inspection of Machine Parts (FSI-ZRI-A)

Academic year 2018/2019
Supervisor: doc. Ing. David Paloušek, Ph.D.  
Supervising institute: ÚK all courses guaranted by this institute
Teaching language: English
Aims of the course unit:
The aim of the course is to provide students with specific theoretical and practical knowledge in the field of 3D optical digitization and their appropriate use in technical practice.
Learning outcomes and competences:
Students will be able to effectively apply the methods of optical digitizing in solving multidisciplinary problems during solution of semester projects, theses and later in practice during development of new products.
Prerequisites:
Knowledge in area of CAD systems (CATIA, Creo Parametric, Rhinoceros, Inventor) and finite element method (Ansys).
Course contents:
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.
Teaching methods and criteria:
The course is taught through lectures explaining the basic principles and theory of the discipline. Exercises are focused on practical topics presented in lectures. Teaching is suplemented by practical laboratory work.
Assesment methods and criteria linked to learning outcomes:
Course-unit credit is awarded on the following conditions: elaboration of semester project, submitting data and the poster in digital form.
Examination: will be granted after successful completion of the test focused on gained theoretical knowledge.
Controlled participation in lessons:
Attendance at lectures is recommended; attendance at practicals and laboratory practicals is obligatory and checked by the lecturer. Compensation of missed lessons depends on the instructions of course supervisor.
