Camera Calibration / Fiducial detection having trouble detecting generic fiducials in b&w imagery.
« on: March 10, 2024, 02:11:23 AM »
Hi,
I am currently working on a project with historical imagery that has been scanned. They all have 4 "generic" style fiducials as shown in the manual. However when I run detect fiducials it is missing a good 80% of the images (about 1500) There are to many images to do it manually is there anyway I can set a threshold or setting to get it to see the fiducial markers? I have never had this issue before with Color/Cir imagery. I have tried it with background mask and without. I am attaching a screenshot as an example of my results. As you can see auto_0, through 3 are no where close to the fiducial markers. I have also attached a close up of the fiducial which according to the manual should be detected as generic. All of my images are in the same calibration group. Any help would be appreciated.
Thanks
