Hi,
I'm very interested in the new fiducial support, as it greatly reduces the effort of using analog imagery. I can however not make it work completely, as marker placement seems non-functional.
If I use the images separately as non-analog, the marker placement works (as bad as it does without fiducials). If I specify the fiducials and place a marker, it ends up on the other side of the solar system. Below is an example of an estimated coordinate I get, from a point added through the sparse point cloud:
East 8 144 283.304 m
North: 13 169 867.186 m
Altitude: 7 982 093 517.095 m
The pixel error is also massive, at 2895.922.
My suspicion is that the internal coordinate system produced by fiducial placement is wrong, creating invalid marker projections and therefore the position. The fiducials I have in the same project are:
X,Y in millimeters, with the focal length: 152.83 mm
Upper left: -106.073, 105.904
Upper right: 105.919, 106.098
Lower right: 106.06, -105.902
Lower left: -105.906, -106.099
I've tried it in several projects, and with different X and Y directions (positive X or negative X etc.). I've also tried the calibrate fiducials tool with no change.
Reproducing the problem is as easy as importing the images, placing fiducials, calibrating them, aligning the images and then placing a marker in the point cloud.
I would love to have the tool working, but evidently it's clearly not!
