PARAMETRIC MODELING AND DIGITAL SURVEY
Module DIGITAL SURVEY

Academic Year 2023/2024 - Teacher: CETTINA SANTAGATI

Expected Learning Outcomes

The course aims to provide students with a critical approach to the IT tools for surveying and architectural representation with particular regard to 3D acquisition digital techniques of real objects for proper documentation of the same, data processing techniques, H-BIM approach for Cultural Heritage, Virtual and Augmented Reality for the visualization and communication.

Course Structure

The course consists of theory lessons, envisioned to critically understand the available instruments and the areas of applications, and practical exercises addressed to achieve familiarity with the IT tool. During the course, there will be organized several workshops to deepen some fundamental arguments.

Required Prerequisites

It is recommended that students have already taken Architectural Drawing 2 and Laboratory, History of Architecture 1 and 2 courses.

Attendance of Lessons

Attendance is mandatory. The student is required to attend at least 70% of the course lectures.

Detailed Course Content

The course will address the following topics:

- Numerical modeling techniques;

- reality based 3D acquisition techniques: TOF laser scanner , triangulation , structured light : from the acquisition to data processing;

- Basics of photography;

- Digital Photogrammetry and image based modeling techniques;

- From the 3D model to its Interpretation and representation: generation of elevations, sections and orthophotos;

- Reverse modeling techniques: from the numerical to the mathematical model;

- BIM for Cultural Heritage: Parametric modeling semantics of Architectural elements

Furthermore, there will be organized seminars on specific topics inviting the field Experts

Learning Assessment

Learning Assessment Procedures

The final examination consists of an oral discussion, which can only take place after the delivery of the assignments relating to the exercises carried out during the course. During the oral colloquium, mastery of the IT tool will also be ascertained in relation to the topics covered during the course.
