Description:

The course is intended for students interested in 3D terrestrial laser scanning. The main topics are basic principles and theory of laser scanning systems, basic types of terrestrial and aerial laser scanners and overview of selected laser scanning systems, influences on measurement accuracy, general procedure of measurement processing (point cloud processing), practical use in surveying, architecture, construction and related fields, introduction to selected software for point cloud processing, economic benefits.

Contents:

1. Theory of operation of terrestrial scanning systems. Physical principles of scanning systems. Safety of work
2. Measurement procedure and processing of measured data
3. Digital Terrain Model. Delaunay triangulation, SLAM
4. Overview of terrestrial scanning systems
5. Airborne Laser Scanning
6. Application of terrestrial systems. Economic benefits

Seminar contents:
