Hi again, I have surveyed one of our company’s coal stock yards.
I used several GCP put in place with RTK GPS.
The error I have found is the point cloud is on average 300mm higher than where they should be, when compared to the check survey done on foot with the RTK GPS.
Unlike the previous issue with the camera calibration this has shifted the whole survey up 300mm and NOT a scale problem.
Whats concerning is that the GCP and the check points do not show there being a problem.
