If the Project Status Items reports weak camera calibration image coverage (see Camera Calibration) this means the point coverage from the camera’s calibration project is smaller than the threshold listed on the Project Review Settings Dialog.
Assigning a camera with poor calibration coverage can produce a weak project if there are lots of marks placed outside of the area that was covered during calibration. Redo the Camera Calibration to improve the coverage, load the new camera using the Camera Viewer Dialog and then assign the improved calibration to each image using the Photo Properties. Or, if your project has a suitable setup try Field Calibration.
