Hello EE,
chunk.crs should correspond to the coordinate system used for cameras/markers coordinate measurement, unless individual .crs are set for markers and cameras.
If you are looking to get the results in the same coordinate system, in which the markers of your project are measured, I suggest to set chunk.crs in accordance to the markers crs. If it is local coordinate system that is not convertible to geographic systems, the workflow might be the following:
- add images,
- load geotags (WGS84),
- set chunk.crs as WGS84,
- align photos,
- uncheck cameras in the Reference pane (for each camera set camera.reference.enabled = False),
- switch chunk.crs to the Local Coordinates (or other system corresponding to markers),
- add markers and load coordinate information for them,
- optimize alignment and proceed with the further processing steps.
