Maybe got a breakthrough: The ending in my PS XML was .JPG, in PS the name of the photos was .jpg
Now my cameras are all aligned, but the next problem is waiting for me.
There have not been any tie points created after importing the camera. Also with creating them manually later "Tie Points- Build Point Cloud" no tie points are created. From the console log I can see that there are points, but it seems PS could not match them.
After this I imported some more photos of the object without know external orientation, from a DSLR.
Still no tie points detectable..
I added btw. the PS XML after camera export
How could I get the tie points? I need them for the dense image matching.
