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.

Does anyone know if eATE is available in Imaginie Photogrammetry or do I strictly need the Imagine Auto DTM Module to use eATE?
