Great video, helped me a lot as I'm new to photogrammetry, however I'm having some problems with my research project.

 

None of my images are aligning, even the ones wtih 4 GCPS. ANd no output las file is being generated

 

TIe points

Image quality seems poor, but these are my tie points, and I managed to go through all of them, and they are all accurately placed.

This is the output, and as you can see it is really bad. I have tried for just vegetation images and still can't get images to align despite working hard to get good tie point collection. Is there something I have missed.

I think it is due to the quality and number of tie points extracted. As IMAGINE PHOTOGRAMMETRY does not use detectors like SIFT, SURF, not enough tie points are found. Having a great number of corresponding will increase the robustness of the registration of both image by getting the chance to remove outliers.
