1-Week Short Course

for Post-Graduate Students in Photogrammetry and Remote Sensing

ALTERNATIVE SENSOR ORIENTATION APPROACHES IN PHOTOGRAMMETRY

Date: 6-10 June 2005 (+ later in Autumn a Post-Graduate Student Seminar)

Lecturer: Prof. Clive Fraser, Dept. of Geomatics, University of Melbourne, AUSTRALIA

Venue: TKK, Inst. Of Photogrammetry and Remote Sensing, Hall M1, Otaniemi

Credits: 2,0 cr for the lectures and exercises + 1,0 cr for the presentation + 2,0 cr for the paper

Synopsis:

Digital imaging technology has had a profound impact on the science and technology of photogrammetry. This has been especially the case in two areas: high-resolution satellite imagery (HRSI), and the conduct out photogrammeric surveys using consumer-grade digital cameras. Both these innovations call, for different reasons, for sensor orientation models that constitute alternatives to traditional photogrammetric models. The need for alternative orientation models is driven partly by the characteristics of new HRSI sensors and off-the-shelf digital cameras, and partly by the desire to provide robust, flexible and highly automated product generation systems suited for use by non-photogrammetrists. This 1-week course will cover alternative sensor orientation in HRSI and close-range photogrammetry. It will comprise class-room sessions of theory as well as practical exercises in sensor orientation utilizing specialized, state-of-the-art software systems. At the conclusion of the course the student will understand the theory and practice of alternative sensor orientation modeling in photogrammetry, and will have had practical experience with implementation of the concepts covered.

Later in Autumn there will be a Post-Graduate Student Seminar for student presentations in related subjects. Topics of these presentions must be discussed in advance, students are encouraged to suggest their own topic.
