Problem with align of forested images

[Solinko]

Hello,

I have images with continuous forest without leaves (total 55). There is problem with align in Photoscan. Can somebody help me where is problem? When I made images I had set 68% overlap. Is problem with small overlap, or Photoscan has problem with images with continuous forest? I attached 4 images. Thanks for help.

Are those the original images? As in are the made photographs 800x600?

No, I had to resize their because here is allow attach only 768KB.

Original images is possible download here:

I was able to do a forested area similar to yours, however, I think ours was flown a little higher to allow (350m AGL?) for more chance at matching features.  It was tricky and it did not accept all the images for every site, even with known camera position.  I have not excelled in this type of landscape yet.  Still in the trial and error mode with the various settings.  Try low density point cloud if you make it past the alignment part.

We had flight altitude 190m. I want to try connect smaller amount of pictures, but I do not know if it helps. Has anyone any other suggestions?

This suggestions are good for next projects  . But now I need to solve the already finished images and I can't return in those area.
