4. CONCLUSIONS
The paper presents a method to use terrestrial panorama
images to detect changes in glacier surface. Series of
concentric images were taken at test fields on Engabreen and
Hintereisferner. The camera places were situated similarly to
normal case of terrestrial stereo photography. Series of
concentric images were combined to panoramic stereo pairs,
which were oriented relatively, absolutely and by single
images. The relative orientation of images was basically
acceptable, excluding the far ends of images, where pixels
stretch.
Movements of the projection centre during the photography
of an image sequence cause difficulties in relative orientation
and distortion to stereo model. In practice the residuals of the
side images of a sequence grow. In this study the residuals
