I am having a hard time trying to process this dataset:
Sony Qx1 5456x3632 25mm lens
100m flight height
Corridor mapping with 4 lines
Photos taken every 25m
This is my last attempt
Options: auto-boundary: true, crop: 0, debug: true, dem-gapfill-steps: 4, dem-resolution: 8, dsm: true, dtm: true, matcher-neighbors: 0, mesh-size: 300000, min-num-features: 20000, orthophoto-resolution: 1

So, my ortho is incomplete, missing several photos and I am trying to improve the results.
What I have noted so far:
- the ortho reconstruction stops around an hard area with dense vegetation. Makes sense, dificult to find good features…
- the GPS errors (8.71) are too high and makes no sense to be, because this was recorded using PPK
- changing --gps-accuracy from default 10 to a lower value (like 0.25) didn’t changed the results
- on previous works, the auto camera parameters gave me “v2 sony ilce-qx1 5456 3632 brown 0.0”, however now I am getting “v2 sony ilce-qx1 5456 3632 brown 0.85” with this dataset.
Could some one please take a look at my data set and give a few hints and advice please?
Is my dataset of bad quality? Is the sobreposition too low?
What is the diferrence of “brown 0.0” and “brown 0.85”?
