LEARNING OUTCOMES
Basic purpose of this course, following that of Photogrammetry I, is to convey to students the necessary adequate knowledge regarding the processes of image block adjustment (aerial triangulation / phototriangulation) and the processes of reconstruction, particularly those involving the modern photogrammetric systems, the photogrammetric products, the planning of photogrammetric projects as well as their accuracies and specifications. At the same time the students acquire deeper insight and familiarity with the mathematical models and adjustment techniques through which the basic photogrammetric processes are performed.
After completing the course, the students:
- Have got to know the concepts and techniques of modern photogrammetric practice
- Have comprehensive theoretical knowledge regarding bundle block adjustment and photogrammetric 3D reconstruction
- Have been practically familiarized with modern systems and the software of photogrammetric processing as well as with today’s photogrammetric products (DTM, 3D scene models, orthomosaics).
- Are in position to address basic photogrammetric tasks via suitable methodologies and systems or software, by adapting the photogrammetric process to the requirements of each particular project.
- Will be capable to develop algorithms for the application of the above methods.
- Will be in position to design photogrammetric studies taking into account the given accuracy levels and specifications.
General Competences
- Search for, analysis and synthesis of data and information, with the use of the necessary technology
- Working independently
- Working in an interdisciplinary environment
- Production of free, creative and inductive thinking
