Description

How did you install ODM? (Docker, installer, natively, ...)?

Docker 3.0.5

What is the problem?

Camera orientation isn't being parsed correctly, as evidenced with attached dataset (21 images). Incremental process works fine, triangulation does not.

https://community.opendronemap.org/t/sfm-triangulation-and-orthophotos-very-strange-results/14597/9

What should be the expected behavior? If this is a feature request, please describe in detail the changes you think should be made to the code, citing files and lines where changes should be made, if possible.

SFM triangulation should produce an ortho that isn't 'garbled'.

Examples from sample provided dataset:

Triangulation:
image

Incremental:
image

How can we reproduce this? What steps did you do to trigger the problem? If this is an issue with processing a dataset, YOU MUST include a copy of your dataset AND task output log, uploaded on Google Drive or Dropbox (otherwise we cannot reproduce this).

docker run -ti --detach --rm --tty --name odm_container -v /odm/datasets/project:/datasets/code opendronemap/odm --project-path /datasets
--auto-boundary
--orthophoto-resolution 1.5
--gps-accuracy 0.03
--sfm-algorithm triangulation

Research direction

Start by reproducing the Docker command with the linked 21-image dataset, comparing the SFM triangulation output with the incremental output. Trace how camera orientation is parsed and passed into triangulation; done means the triangulated orthophoto is not garbled.
