Hello,
I have a question regarding photogrammetry using thermal images of a small river bed. While Metashape is (understandably) not able to align the water-parts of the images, it can align features of the riverside.
In a few test images, we were able to get a point could based on one riverside. In the rendered model, it also shows colours for the water part. Since there were no tie points detected in that, I assume the colour is some sort of interpolation. Can someone tell me if those results could be of any use (with regards to tracking temperature differences of the water surface)? How does the interpolation happen?
If we took good care that each photo contains part of the riverside on both sides of the photos, would that possibly give us a model of the water in between as well?
Best regards
Karen
