93668 - 3D Image Analysis and Computer Vision Systems

Learning outcomes

The objective of this Course is to form an engineer able to design computer vision systems working in the real world, even in real time, for industrial, scientific and play purposes. The systems exploit automatic analysis of 3D image sequences in a number of application fields including machine vision, automotive, automatic quality control, zero-defect analysis, predictive maintenance, security, medical and biomedical imaging, aerospace imaging, precision agriculture, cultural heritage. At the end of the Course, students are able to apply the acquired skills:

• To apply computer vision in critical multidisciplinary fields, including medical imaging
• To use cameras to perform high-accuracy 3D measurements
• To realize augmented and mixed reality applications
• To use vision sensors in IoT applications
• To perform 3D scene reconstruction from moving aerial or terrestrial vehicle
• To perform 3D scanning, also for 3D printing
• To perform 3D defect analysis in industry
• To design real time computer vision systems on parallel/distributed architectures

Course contents

Readings/Bibliography

• R. I. Hartley, A. Zisserman: “Multiple View Geometry in Computer Vision”, Second Edition, Cambridge University Press, 2004

Teaching methods

Classroom lessons and practice in lab. Each topic will be treated jointly with significant case studies developed in lab to highlight its meaningful applications. In order to make the students aware of the different topics, many homework exercises will be proposed and publicly corrected afterwards in lab.

Assessment methods

The students will be evaluated on the basis of homework assigned at the end of the main lectures (12/30), a computer vision project (15/30), developed either alone or in a small team, and an oral examination (6/30) regarding the most theoretical aspects of the topics presented. Honours will be marked when proving to use effectively the computer vision theory on a practical problem

Teaching tools

In the teaching material section all the slides shown in class are available for download as well as the software tools for practice in lab
