Course contents:
Lectures: The perspective projection. Linearisation and differential formula, formula development. Estimation of external orientation elements, Spatial re-section. Aerial triangulation, bundle block adjustment. Sources of error and quality. Mapping with drone. Relevant standards. Digital elevation models - production and use of, accuracy in DEM. Digital elevation models - interpolation and production of contour lines. Image matching. Ortophotos - production and use, accuracy of ortophotos. Digital aerial cameras - principles and modes of operation, geometrical and radiometric properties. Airborne laser scanning - introduction, instruments, principles, modes of operation, accuracy, fields of usage.
Exercises: Exterior orientation of a single image using bundle adjustment. Image matching. Project: Mapping with drone.
Learning outcome:
The students should have knowledge, understanding and some practical skills related to the orientation of images (taken from airplanes and satellites). This includes knowledge and understanding of the mathematical, optical and photographical basis of photogrammetry, the perspective projection, 3D-transformations and model deformations. Further, knowledge of and an understanding of various types of photogrammetric measurement and digital mapping, through both manual and automated methods, as well as the processing of data for presentation. In addition, practical skills in the use of relevant software. Introductory knowledge of airborne laser scanning is also included.
Learning activities:
Lectures, exercises and project work.
Teaching support:
Teaching support will be given primarily in connection with that part of the structured teaching that is set aside for exercise guidance. It will also be possible to communicate directly with the subject teacher by appointment during office hours.
