Following on from a similar discussion here I removed any images where there was horizon in the shot and reprocessed.
The chemical towers are much crisper, but still lacking a little higher vertical detail…
The flight path for these looks like this…
And the individual renderings in Pix4D look like…
The top of the dam is much improved…
The treatment tanks have not benefited much. I suspect that these need more oblique to get the detail. That gantry looks pretty wavy for a straight lump of metal.
Again, the flight path, which you will see has an incomplete orbit. That is because some of the images were pulled from the set.
and the Pix4D…
Generally, though, pre-sorting the imagery to pull out anything <45° or containing (significant) horizon has improved the output quality of the model a fair amount.
