I am attempting to create an orthomosaic in ArcGIS using the Imagery & Orthomapping tools.
When I add my UAV-captured images to a new ortho mapping workspace, I am presented with the following warning errors:
Error: 8004206c: Failures reported while processing specified command item. 
Error: 80042019: Chained Error ID: 0X80042019
Error: 80042019: Could not build mosaic dataset item.
Error: 8004103f: Creation of frame camera model failed.
before the whole thing falls over with:
ERROR 999999: Something unexpected caused the tool to fail. Please refer to the error help for potential solutions, or contact Esri Technical Support http://esriurl.com/support.
Failed to execute (AddRastersToMosaicDataset).
What is causing this error? Could the problem be that ArcGIS Pro does not have my camera model (FC300C) in it's database?
