Problems trying to build a DEM from aerial photographs
I have some problems trying to build a DEM from aerial photographs. I have a pair of stereo images and 11 GCP (tooked by dGPS on the field) very concentrated in only one valley, and I don't have any real GCP for the rest of the picture.
I've imported the .txt file with the GCP coordenates and I put one by one in one of my photographs, but when I try to link these points to second photo, I can't do it because the software starts to "processing...." for a long time, more than 6 hours.
I entered all the camera data correctly, so I don't know what is happening in this case.
I've tried to do alternative processes (enter data manually, with a geocode image, etc) but is impossible. Always when I run "compute model" is the same case: always appear the "processing..." window for a long time.
What can I do?
