Photogrammetry

Introduction


This course introduces photogrammetry as a data acquisition tool, and provides a general overview of its theory and working principles. This course covers the factors that influence the formation of the photographs, and the process of reconstructing the three-dimensional model for the real world.
Students will gain the ability to extract data from aerial photography. The typical geometry of a photograph and the basic mathematical formulations are introduced.

 


Learning outcomes


At the end of the course, students should have a good knowledge on how to acquire different types of remote sensing imagery and the basic algorithms to process and analyze remotely sensed images. Students should to be able to apply and develop photogrammetry for production of spatial data and for non-topographic applications, to plan aerial photogrammetric spatial data production and to analyze the resulting quality. They will also be able to apply the image orientation procedures to generate topographic products such as orthoimages and topographic maps. They will understand how to evaluate and analyze the quality of topographic products such as topographic maps, georeferenced images, orthoimages and DEMs.
