Course detail
Reconstruction and Analysis of 3D Scenes
FSI-SR0-A Acad. year: 2025/2026 Summer semester
The subject concerns the reconstruction and analysis of 3D scenes that are based on point clouds. This research area is important in the reverse engineering, robotics, geography and autonomous traffic systems. First part of the lectures deals with the data acquisition types and algorithms as registration, edge detection, feature extraction. In laboratory we make the measurement with optical scanner ATOS and other hand scanners. We will process the point cloud with software GOM inspect and Rhinoceros. We will also work with 3D printer Voxelizer.
We will use Arduino Engineering Kit for testing of proposed algorithms.
Students prepare their own implementation of some of the algorithm in the last lectures of semester.

Entry knowledge
elementary knowledge of mathematical analysis and algebra (matrix, derivative), computer graphics, the recommended is the knowledge of programming language (C, C++, Pascal, atd) or programm (e.g. Matlab).
Rules for evaluation and completion of the course
Students will prepare the project and present the project on the end of the semester.
The lecture attendance is compulsory.
Aims
The main gist of the subject is to understand the point cloud and its processing algorithms. The practical part will show the 3D scanning and 3D printing technology and the 3D scene algorithms.
Students will learn about the point clouds, its acquisition (3D scanning), usage (3D printing, Arduino scene analysis) and post-processing (edge or object detection, registration).
