Courses
3D Modelling for city digital twins based on geospatial information - elective course (starting in November for 10 weeks)
Introduction
This course is suitable for all specializations of ITC and students from UT (e.g., Civil Engineering, Computer Science, or Creative Technology). It aims to provide the student with knowledge of different 3D city/building modelling methods (as a base for Digital Twins), based on geospatial information. The students will be given the opportunity to practice with a variety of applications (e.g., GIS, BIM, image-based, gaming, or Virtual reality and Augmented reality) to develop and interpret their own 3D city/building model. To achieve this, theoretical and practical activities where the student can learn different 3D city/building modelling techniques and methods, used in a variety of applications, based on geospatial data are used. The student will have the opportunity to work on a 3D modelling/Digital Twin assignment.
Content
3D city modelling as a base for Digital Twin creation:
- 3D modelling (geometry, topology, semantics)
- 3D city modelling (categories, standards, methods, formats)
- 3D reconstruction from images
- 3D visualization (Virtual reality/Augmented reality)
- 3D city modelling/Digital Twin applications
- 3D spatial databases
- 3D data integration BIM/GIS (e.g. for infrastructure/utilities, using FME)
- Principles of parametric and generative design (using Dynamo/Refinery)
- CityGML (using FME)
Laser scanning - elective course (starting in April for 10 weeks)
Introduction
Airborne, terrestrial and mobile laser scanning are modern technologies to acquire and monitor the geometry of the Earth's surface and objects above the surface like buildings, trees and road infrastructure. This course provides an overview on the state of the art of these techniques, potential applications, like digital terrain modelling and 3D city modelling, as well as methods to extract geo-information from the recorded point clouds.
Content
- Principles of airborne, terrestrial and mobile laser scanning
- Sensor and point cloud properties
- Point cloud registration, accuracy potential, error sources and correction methods, quality analysis
- Comparison to other data acquisition techniques
- Overview on various applications
- General point clouds processing: visualisation, segmentation, classification
- Digital terrain models: extraction of terrain points and break lines
- Detection and modelling: 3D building modelling, 3D landscape modelling, extraction of vegetation characteristics, change detection with multi-temporal and single epoch data for map updating
