Course detail

3D Optical Digitization and Inspection of Machine Parts

FSI-ZRI-AAcad. year: 2020/2021

The course provides information in the field of industrial metrology with a focus on 3D metrological systems, standardization and measurement errors, digital data processing, inspection of machine parts and reverse engineering in mechanical engineering. Practical and theoretical knowledge in the field of modern metrology increases the interdisciplinary focus of the structural engineer.
