Re-use Alignment

This short tutorial explains how to go about using a set of parameters over and over again (for example when doing full-body scans) and to make the workflow much faster. That is when extended Metadata (XMP) come into play. Read on.


Camera Poses

This part is especially important, so we will have a closer look at it in a separate paragraph in which you will learn about how a camera pose will be exported for a particular image, depending on your choice in these export parameters:

Depending on how much you trust your registration, you can select the following options or you can also choose not to export camera poses:
Export as draft This will treat poses as an imperfect draft to be optimized in the future. The draft mode functions also as a flight log.
Export as exact if you trust the alignment absolutely. By choosing this option, you are saying to the application that poses are precise, but the global position, orientation, and scale is not known.
Export as locked This is the same as the exact option with the difference that the camera position and calibration will not be changed, when locked.

Further you can choose what more to export:
Merge with existing XMP files When set to True, files in common will be replaced by new ones, and new files will be added.
Export rigging setup Select to export rig membership information. If False, only positions/orientations are exported - like they were not in rigs.
Export camera calibration groups Select to export the information on the created calibration groups. More about calibration groups: here.
Include editor options Export editor states, e.g. enabled/disabled flags for texturing, meshing, and similar.
Replace EXIF GPS with optimized values Force replacing original GPS coordinates with the ones calculated during alignment.
