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
