batch editing for camera calibration groups
« on: July 01, 2020, 04:26:35 AM »
Hi, I've been using high-res scans of historical aerial photos and would love to see a couple of changes in a future version of Agisoft. It's possible I just haven't discovered the solution for some of these and they already exist, so sorry if that's the case.

Camera calibration dialogue box:

     - Batch selection of calibration groups for editing: photos get split into many groups with scanned images even if they’re the same survey set because scans may have a slightly different number of pixels. It would be helpful to be able to select all the groups to edit variables that are the same, like focal length, fiducial names/labels and coordinates, etc. If I try to mass-edit the information by selecting multiple groups at once and adding information it causes the program to freeze for a while.
     - The problem mentioned above is fine for checking the “film camera with fiducial marks” box, I can select all the groups and check that box and then run the auto-detect for fiducial.
     - Separate the auto-detect of image border masking from the fiducial recognition in case fiducial types aren't recognized, but the mask extent is.
     - Some fiducial types aren’t supported, such as "dot" fiducials in the center of the image borders (e.g., top, bottom, left, right). For example, from for Zeiss RMK cameras.

Common steps for the scanned images with the fiducial marks are the following:
- in the Camera Calibration dialog select all groups related to the same camera,
- enable "Film cameras with fiducial marks"  option,
- right-click on selected groups and choose Merge Groups option.
After that add and start placing fiducial marks.

If you would like to see additional types of marks supported in Metashape, please send the images with such examples (or links to the public available data) to support@agisoft.com.
