I have invested considerable time and effort manually aligning 6 ground control points with 316 instances across 746 drone-captured images from a remote site in Greenland for my research project. Notwithstanding my frustrations with this process pulling the resulting component into misalignment with the ground plane (where it all looks fine when I auto-align without the survey control). I now have a much bigger problem…
After an overnight PC sw update and restart w/ my RC project open, RC has now lost access to the image files. I cannot run alignment, or texturing without an access denied error, and the images are displayed as pixelated with the ‘wait cursor’ (… in the UI) indicating that RC is trying to access the image file.
I can see the images fine in Windows Explorer and there are no Windows file access restrictions in place. This problem occurs across both previous versions of the saved project (i.e. file save as for a new version as I try something else to improve the ground control alignment, like turning off exif data from the drone images).
I am using the PPI version of RC, which is really frustrating as the licensing for the images seems to not be transportable when I migrate to a different file structure or a new PC.
May have solved this… clear cache didn’t work, but restarting RC with the shift key held down and resetting the application is now accessing the images at high res.
What I would like to know is what this has actually reset? is it the crmeta files in the image folders? what do these files do, store PPI registration data for images? Resetting the application was a leap of faith for me with multiple late nights invested in manually aligning the ground control points and fear that this painful work would be lost.
I was not aware of the download options for the license, does this stay with the images? Can you point me at the procedures.
The PPI licensing has all been a bit of a mystery. I have migrated to a new PC, but couldn’t open the project on the new PC. I tried editing the rcproj file to change the PC name and ran a batch file to change all the image directories in teh rcproj file, but RC then reported the file as corrupted when I tried to open it. I ended up starting the project from scratch again and paying twice for all the same image licenses.
I also have LIDAR and ground camera high res models to merge with my drone model, however, they were produced in a fully licensed RC and don’t seem to be able to be used in the PPI version.
