The Pro Ortho Mapping App is built on top of Geoprocessing tools and mosaic dataset data model. But from the error message, it seems that you didn't define your camera parameters properly. Creating mosaic dataset outside of Ortho Mapping App might not help. I suggest that you make sure that the camera parameters are correct (the units for focal length, pixel size, and principal point are all in millimeters), if it still does not work, please send your data to technical support and we can investigate.
In case you are interested in building mosaic dataset manually using geoprocessing tools, here are the steps
To create a mosaic dataset from your drone images, you may use:
- Use Create Mosaic Dataset too to create a mosaic dataset
- Use Add Rasters to Mosaic Dataset tool and use UAV raster type to add your drone images to the mosaic.
Please note, in Pro 1.4 release, the mosaic dataset created in outside of Ortho Mapping App will not be able to import to ortho mapping workspace (this will be enhanced in future release). you can use Compute Camera Model GP tool to do further processing.
Hope this helps
